Too hateful, how can Shang Gengyu be so treacherous to dig a trap for her to jump? Bring her to New York. That proves how little she knows about him. Because if it were her? She would never give such a lovely child to anyone else. 。 Why did Shang Gengyu oppose Andrew to take care of his mother-in-law? Because he has no job. Can't afford a child? Only half a day after setting foot in New York, she was convinced by what was in front of her that she really didn't understand Shang Gengyu at all! He Xuwei looked at the hot water that began to smoke on the stove and felt so confused. She was puzzled by the enigmatic Shang Gengyu and why she lied just now-she didn't tell Andrew honestly, but casually said an English nickname because of her English name. Also known as Vivian! For the sake of some kind of selfishness, Xu Wei did not want to use the same name as Shang Gengyu's wife who had passed away. Jealous of a dead person feels immoral, but she can't control it. Is she really jealous? FM1046 FM1046 FM1046 FM1046 FM1046 FM1046 FM1046 He Xuwei thought that a child's birthday party was. A simple birthday party. It's a pity that she was so wrong. She should have guessed that Andrew's birthday party would not be just a child's party, judging from the one-piece red dress Andrew gave her, which was full of silver highlights with refraction effect. Andrew gave her a dress that was as formal as if she was going to some big award ceremony. He even prepared a pair of Burgundy heels for her to match the dress, as well as a set of white diamond hair accessories and necklaces. Xuwei received these things from Andrew this afternoon. She hesitated to accept them. She was afraid that if she accepted them and really wore them, it would be too formal. Shang Gengyu assured her that those clothes and accessories were absolutely appropriate to wear to Andrew's party. Shang Gengyu also said that because he forgot to remind her to prepare a dress for the banquet, he wanted to take her to rent one, but Andrew said he wanted to buy one for her as a gift. The dress, shoes and accessories were all chosen by AndreW. Shang Gengyu said Andrew liked her very much. Anyway, she has a lot of clues to follow, and AndreW's party should not be too unusual. However, when the car that picked them up arrived at the luxury house, He Xuwei was shocked for a long time. Because what she saw in front of her didn't look like a nine-year-old's birthday party at all! Among the adults who entered the party, the men were all wearing formal suits; the women's gowns were one after another. As for the children, the little boys were all dressed like little princes, and the little girls were dressed like little princesses. Compared with the clothes of those people, Xu Wei's dress is simple and generous. The party was held at seven o'clock in the evening. The venue was many long trellises set up outside the house. There was a large stage in front of it. A black singer was singing. When she got out of the car, she took Shang Gengyu's hand and saw Andrew walking towards them. Didi, you look beautiful tonight! The clothes I sent you. Do you still like it? I love it! Thank you for the gift. But I insist on giving you back the money for these things. You're still a child, radio shuttle racking , and you can't make money yet. It doesn't matter, Didi, all my money is Daddy's pocket money. If I buy it for you, Daddy will buy it for you. And as you said, I am still a child, I can not use so much money, it is better to use the money to buy things for the people I like. Daddy said he was embarrassed to buy it for you because he was afraid that you would misunderstand that he had bad intentions. If I buy it, you won't misunderstand. Is that so? So you Daddy has his moments of embarrassment too! Yes! The man of our business. When you meet someone you like, you feel embarrassed. "Imp!"! You talk too much. 。」 Shang Gengyu rubbed Andrew's head, then crouched down and gave Andrew a big hug, saying in his ear, "Happy birthday, son.". 」 Seeing that Shang Gengyu loosened his arms and stood up, Xu Wei also bent over and kissed Andrew twice on both cheeks, saying to Andrew, "Happy birthday." "Didi, thank you for coming all the way to my party with Daddy. Those two kisses will make Daddy jealous." What is jealous of me? You should say you are jealous of me. 。 Besides, your father wasn't that mean. Shang Gengyu corrected Andrew's language. All right. Be jealous of me. You go in first, and I have to wait for a girl who makes me embarrassed. By the way, Daddy, there are a lot of people in the head office. They are looking forward to seeing you today. You will be busy later. Don't neglect Didi then. Yes! You are the birthday girl You're the oldest today. I'll do whatever you say. Wait for your Vivian to come. Remember to bring it to Didi and me. Yes, sir. Didi, I hope you have a good time. If Daddy is not well treated, you must forgive him. He's been away from New York for so long that a lot of people miss him and want to take this opportunity to talk to him. I don't mean to ignore you. FM1046 FM1046 FM1046 FM1046 FM1046 FM1046 FM1046 Andrew is not exaggerating. He Xuwei holds Shang Gengyu's hand and walks slowly from the gate to the lawn where the party is held. Shang Gengyu is immediately surrounded by several Westerners. At first, he thoughtfully introduced her to others. Xuwei was not unaccustomed to such a business occasion, but it happened at a child's birthday party, which was a little hard for her to imagine. After maintaining a certain degree of politeness and greeting the friends whom Shang Gengyu seemed to be very familiar with, she went to fetch the food and left Shang Gengyu to his "friends.". She is extremely curious about her surroundings, but rather than being curious about everything around her, she is curious about "Shang Gengyu.". This room should be the mother's home of his deceased wife. omracking.com

Small circle confused, confused for two seconds, replied: "One by one to check the project to do the past, there are many instruments are not a day to produce results..." "Oh." Coming out of the building that Chu Wenzhou had inspected, Xiao yuan said, "Are you very nervous, Miss?" "Why do you think so?" "Your hands have been rubbing the corners of your clothes." “……” Nanyan bowed her head. Today she was wearing clothes and trousers, a rare casual dress. Hot pants were nothing. The silk vest and the hem of the jacket were rubbed out by her hands. Nan Yan stroked the corner of his coat and coughed lightly. "I'm not used to being in a strange place," he said without looking at Xiao yuan. Small circle; "… …" Second young lady, don't look at the scenery. Look at me. Do I look like an Ako who can believe it? The small circle does not expose, the south smoke also no longer moves the claw, all the way to the diagnosis room, the south smoke sits down, changed the posture four times in a row, after several times repeatedly licks the lip, Fang said: "Doctor Hello." The potbellied fat doctor sitting opposite held his glasses, and after Xiaoyuan translated, he nodded back: "Hello." Next, under the quick translation of Xiaoyuan,warehouse rack manufacturer, the communication between the two people is on the right track. Fat Doctor: "What is the relationship between the patient and you?" Nan Yan: "I am her niece. She has no children. I am the only relative." The fat doctor nodded, flipped through the cases, and stopped at one of them. By the way, we can see that the patients in China have already started taking the new drugs we developed, right? "Yes." "And then the disease was under control, not bad?" "Yes." The fat doctor nodded his head. As for our understanding of the condition, let me tell you about the medical records, our analysis,Pallet rack supplier, and the follow-up recommendations for treatment. "The patient has not yet undergone surgery, which is a very correct decision. After surgery in this area, the probability of diffusion is too high. It is right to carry out conservative treatment first." "The control of targeted drugs is very effective in patients, and there are no obvious sequelae and other reactions, which is also a very good effect in our clinical trials." "The medical record shows that the patient is currently in the first stage, which shows that the drug has delayed the development of the disease, and the follow-up.." South smoke is stupefied, the upper part of the body leans forward, interrupt: "What do you say, she is in a few period now?" Xiaoyuan and Nanyan looked at each other. They had never seen Nanyan so urgent before. They translated to the doctor. They looked back and said firmly, "You are in the first stage, Miss." "No!" Nan Yan murmured, "How can it be the first phase? Shouldn't it be the second phase?" Confused, Cantilever Storage rack ,Industrial pallet rack, the doctor took another look at the case and nodded: "No, the result of the last examination in Huaguo Hospital showed that it was the first stage. This examination was two weeks ago. It should be relatively accurate." "And if you look at the results of her examination, the condition of the cells is still some time away from the second stage of development." Nanyan stood up and could not believe that from the doctor's medical record, although the handwriting was scribbled and difficult to distinguish, the last line of the diagnosis was indeed written in the first issue. At that time, Nanyan was busy and was preparing for the wedding, so she didn't go to the hospital. Last time she went to the clinic, she boasted that she knew the result. In the chat with the doctor, the doctor didn't mention it again, and she didn't ask about it. Nanyan seemed to be hit by something, his mind was blank for a moment, his eyes blinked a few times, which made Xiaoyuan and the doctor a little stupefied. Xiaoyuan poured a glass of water for Nanyan, and Nanyan held it for a long time. She was really, really surprised. I can't come to my senses for a while. But Nanyan has always had strong self-control, but after a few moments of breathing, he blinked, took a sip of water, and asked questions calmly. If we follow the previous speed and do not use your medicine in the middle, is it the second phase now? The doctor is asked by south smoke: "I look." After looking through the medical records several times, the doctor was proud: "Yes, after the intervention of targeted drugs, the patient's condition has been effectively controlled." Nanyan was ecstatic. "What about the back of her?" The doctor, Nahananyan, was suddenly excited. He coughed lightly and continued: "This is the result of half a month ago. Today, we have an examination in our research Institute. The result will come out almost a week later. If the patient is also in the first stage after a week, we have the follow-up treatment of this drug here." "It is also a treatment that has not yet been fully marketed by our research Institute." “Nirvana？” Nan Yan blurted out. Nirvana. It stands for rebirth. The doctor was stupefied, say slowly: "Look Madam, you have very deep understanding to our project!"! But this is only the internal name, after the listing, definitely need to change the name, now the draft is Nirva. Nan Yan covered his mouth with his hand, his eyes turned red, Xiao yuan couldn't figure it out, and the doctor was confused by Nan Yan's reaction. Can she, can she attend? Nan Yan's voice trembled uncontrollably. If the disease is still in the first stage, it is possible. The doctor's words made Nanyan's heart sink again, and he pinched his fingers tightly. The doctor observes words and expressions, comfort a way: "This development of the patient, if do not have accident, should not arrive 2 period, still relax state of mind please." South smoke Leng Leng nodded, Zhang Huang but a moment, and gather up the spirit to ask questions. What is the recovery rate of this new project? The doctor did not hide his pride: "It can reach 60%. The three-year survival rate of the patients involved is 70%. It can be said that we are the only one in the world to reach this parameter for the current disease." Think of what complexion is dark: "Regrettablly,Narrow aisle rack, it is the condition that treats is too harsh." Nan Yan knows. How could she not know? Since she decided to treat her aunt, Nan Yan has repeatedly recalled her known plot in the book. Aunt's illness develops very fast, and it is almost impossible to recover in the later stage. The main hope of survival is in the early stage. omracking.com

Xiao Yijian is running for his life, and at this time it is proceeding as expected. Bai Bingru is so happy tonight that he doesn't care about what's going on outside the bed. After a while, Xiao Yijian panted like an ox, and Bai Bing was like a pile of mud, unable to move! Moments later, Xiao Yijian said in a low voice: "Jiu Niang, go inside. I'm going to fall!" Bai Bingru wanted to promise, but she couldn't make a sound. She also wanted to move inside, but she didn't even have the strength to suck the breast, so she couldn't move again. The anger in her heart rose, knowing that she had been plotted against, but it was too late, so she had to endure the incomparable hatred and anger, and quickly tried to restore the dark wound with her own True Qi. Xiao Yijian said again: "What's the matter with you, Jiu Niang? Didn't you hear me?" Bai Bingru thought in the dark, is it not Xiao Yijian's ghost, otherwise why did he ask himself again why he did not move? Before she finished thinking about it, Xiao Yijian burst out laughing. Bai Bingru was afraid and hated. She was determined to clean up Xiao Yijian well after her physical strength recovered, so that he was in a dilemma of life and death! After Xiao Yijian stopped laughing, he said coldly: "It's easy for me to kill you now, but we have been in love for ten years, and I can't do it,Pallet rack beams, but I know that one day I will fall into your hands, and you will kill me without mercy, so I have to fly away to a place where you can't find me anymore.". Of course, I will not endure forever, so during my invisibility, I will practice several rare skills, not to deal with you, but to protect my own safety. From Ouyang Yi's words tonight,Steel racking system, I realized a lot of things. If you are not determined to kill me, I still don't want to leave you. In this way, I will tell you a few things before I leave. Although I don't know what oath and secret agreement Mei Sanfeng and you have, but I know that the inner secret is so complicated that it is hard to predict, but you should think of one thing, that is, Ouyang Yi said that in the Wanmei Villa, the matter of "Dongzhongdongtian", if it is true that "Jingtian Gong Jue" has been destroyed, only the one written by Mei Sanfeng is left. Why should Mei Aoshuang travel to Emei to explore the'Valley of No Return '? On the small building of Gaobin Inn, the young man whom you had intended to kill because of you did not die. I saved him. The reason was very simple. I suddenly felt that your means and heart were too ruthless. I saved him with the sorrow of the fox after the death of the rabbit. This man is not Gu Yuecang, nor my Xiao Yijian. Sooner or later, he will become a unique skill and find you at the ends of the earth. You should be careful! Since you and I have known each other, I do not know who you are, but you do not know my origin, heavy duty warehouse rack ,Narrow aisle rack, and now I tell you. In the past, there were three world-famous underworld masters in Jianghu, who were known as the Three Birds of Tianpeng. I am the disciple of the third generation of the Three Birds of Tianpeng, and now I should be regarded as the master of the three birds. However, the disciples of the third generation of the three birds have already died, and my master is just an empty seat. Since I left a message to my first teacher and traveled to Emei, I lost the news. It is said that the three masters once came to the'Valley of No Return '. I vowed to find out the details, so I began to walk in Jianghu. Unexpectedly, I would throw myself under your seat and be the best minister beside you. But I almost died tragically at your hands, which was unexpected! Nine Niang, finally there are two things to tell you, Xiao Yijian other may be a lot of difference between you, but in tact, I am more confident than you, I infer that you are Bai Bingru, yes, but there are many strange medicines in the world, just to stay in the face, maybe it can make sixty old people look like twenty people, but the body given by God can't be changed by any medicine. You have been greedy for the first thing between men and women. How can it be that a man in his seventies should.. Nine Niang, who are you? I don't want to know now, but sooner or later, I will uncover your false face and make you show your true face. Now there is only one thing left. The medicine you have taken is the secret of my Tianpeng Gate. It must break out every few days. When it breaks out, it is the same as you are now. You can't open your mouth or move your body. There is no medicine to cure it. You must endure for two hours. So I advise you to stay in the cave for about a year from the Ming Dynasty. You will experience the day of the onset of the disease, and then as long as you find a place to rest the day before the onset of the disease, you will not be hurt by the outside world when the disease occurs! Jiu Niang, our fate has come to an end. Forgive me for not accompanying you any more. Listen to me. Anyway, you can't move. Why don't you sleep at ease? Bai Bingru only hates his teeth, but he has no alternative. Xiao Yijian uncovered the quilt steeply, revealing the body of Bai Bing like a little white sheep! He looked again and again, and finally bent over and kissed enough from head to foot before he began to float up. He, too, was naked, and as soon as he had picked up his clothes, a cold breath suddenly came from the back of his neck. He was so frightened that he flashed into the corner of the cave in a panic! Staring intently, a dark shadow was blocking the entrance of the corridor. He did not know what to do for a moment, and the wood stood there motionless. The shadow said coldly: "Put on your clothes, quickly!" Only then did Xiao Yijian return to his body and hurriedly put on his clothes: "And the upper body and the long gown, all wear it." Xiao Yijian hurriedly took his clothes and put them on three or two. Go and dress the man in the bed! Xiao Yijian did not dare not listen, immediately obeyed, for Bai Bingru also dressed. In fact, Xiao Yijian's skill is very high, but he does not know why, simply did not think of fighting with this person, perhaps this person suddenly appeared without a sound, has shocked Xiao Yijian. Save her with the antidote! Xiao Yijian this can be difficult, of course he has the antidote, but after saving Bai Bingru, he must die,Warehouse storage racks, so he hesitated and did not start. Didn't you hear me? Xiao Yijian immediately answered: "I dare not save her." "Oh, you're afraid she'll kill you, aren't you?" "She will." "Are you afraid of death?" "It's not a question of fear." 。 omracking.com

"I'm not forcing you," Father snapped. "I'm giving you a chance to be reborn. Shouldn't they know the truth when you almost killed them?" Sophia's whole body shook. She looked at her father in a misty way and said, "The chance of rebirth?"? I "Sophia," said Lucifer, "I want to know very much why you listened to the slander and framed the Diomandus brothers. Even though I begged you, you wouldn't change your mind. You weren't like this before. When we were just created by the Father God, you were like the elder sister of our six first-level gods, taking care of us and leading us to get familiar with the divine world. At that time, I only had great respect and admiration for you. We all sincerely regard you as the king of the divine world, and our loyalty to you can only be expressed by heaven. Even at the time of the first war between the gods and the underworld, we all supported you unreservedly and attacked with all our strength to suppress the underworld. If it hadn't been for the timely appearance of the Father God, I'm afraid we would have destroyed the underworld. Why? Why did you change later? Originally wise and wise, you became so unreasonable that you went to frame our brothers. The more Lucifer spoke, the more excited he became, his fists clenched tightly, and his body emitted a black mist. Yes, mother, why? Why is all this? Phil Yun asked sadly, "Ziyan and I are your own daughters, but why do you want to deprive us of the right to happiness and not give us the freedom to love?" Sophia stood up slowly. She looked at the Father and then at some of her men. Michael, the battle angel, Rafael, the charming angel, and Solent, the army angel, all asked questions. They also wanted to know why. He turned to us,Pallet rack upright, sighed slightly, and said to Phil Yunna and Ziyan, "It's my fault. I'm sorry for you. Since you want to know, I won't hide it any more today. All this has been weighing on my heart like a heavy burden. Father, I don't ask you to forgive me, but please forgive Gabriel. All this is really my fault." The Father said indifferently, "Come on, tell all the secrets in your heart, and everything will be judged by yourself." Sophia nodded her head. She took a complicated look at the dead angel Gabriel and said faintly,pipe cantilever rack, "Since I was created by the Father God, I have become the master of the divine world. In the divine world, I have absolute authority. I am the king of God.". Born after me, in addition to Hades, are your six first-level gods. At the beginning, I treated you as a brother, took care of you, and even loved you. But when the Father created us, he gave us one of the most precious things, that is, emotion. Although I am a God king, I also have feelings. All six of you are so excellent. Lucifer, the angel of freedom, is bohemian, Michael, the angel of battle, is upright, Rafael, Drive in racking system ,heavy duty racking system, the charming angel, has the same incomparable charm as his title, Solent, the military angel, is full of amazing vitality, and Diomandus, the mad God, has the ability to lead. Among you, only Gabriel, the death angel, does not have remarkable characteristics, but everything about him is still so excellent. In constant contact, I gradually fell in love with two people, one is the mad God without wings, Diomandus. She looked at the stunned Diomandus and said with a smile, "Are you surprised?"? I'm telling the truth. At that time, I really fell in love with you. And the other one I love is Gabriel, the angel of death. Gabriel, who had been sealed by the Father, was stunned. He stared at Sophia, apparently unable to accept the fact for a moment. Sophia then said: "At that time, I was very painful, as a God king, how can I easily fall in love with their subordinates?"? However, the feelings of this thing came to the body, but how can not be abandoned. Later, because of the wingless gods, Diomandus left me to lead them. As time went on, my heart gradually shifted to Gabriel. My feelings for him kept increasing. Even I was almost out of control. I suppressed my heart every day so that I didn't think about him, but his shadow kept flashing in my mind. The longer I suppressed it, the more terrible it was when it broke out. Finally, one day, I could no longer control my feelings. She looked at Gabriel crazily and said sadly, "You don't even know now. Yes, I've been holding back and never said it.". I don't know if you still remember that time when you were in seclusion, you lost consciousness for a short time. It was not because of the practice, but because I deliberately caused it. At that time, I, I was blinded by the expectation and gave myself to you without reservation. Sophia's words shocked us all. Although we all guessed that he had an unusual relationship with Gabriel, none of us thought that she loved Gabriel so much. Sophia looked at the dull Gabriel and said with a wry smile, "Am I mean? It was at that time that I changed. As Lucifer said, I became unreasonable." She turned to Phil Yunna and Ziyan and said, "Children, you are all my own flesh and blood, but you have a completely different place.". Sifiya was indeed born by me with energy, but Yunna, you are not. You, you are my child with Gabriel! There was a brief silence in the colorful energy, which was very terrible. Not knowing when the Father had lifted the seal on Gabriel, he rushed to Sophia's side, grabbed her shoulder excitedly, and lost his voice: "You, what did you say?"? Phil Yun, how can that be my child? Our first-level gods can't bear children! Phil Yuna's body shook and nearly fell. Diomandus quickly supported her. They never thought that Gabriel, the angel who had killed them, was Phil Yuna's father and Diomandus's father-in-law. "No,long span shelving, it's not true, it's not true," Phil Yun said in a trembling voice. 。 omracking.com

Original Title: Occupational Hazards and Protection of Carbon Tetrachloride Carbon tetrachloride (CCL) Also known as tetrachloromethane, it is a colorless, transparent, volatile and non-flammable oily liquid at normal temperature and pressure, with a slightly sweet odor similar to chloroform. Its molecular weight is 153.84 and boiling point is 76.8 C | C. It is slightly soluble in water and miscible with ethanol, ether, chloroform and petroleum ether. Carbon tetrachloride has been widely used as solvent, fire extinguishing agent, chlorinating agent of organic matter, leaching agent of spice, degreasing agent of fiber, cooking agent of grain, extracting agent of medicine, organic solvent, dry cleaning agent of fabric, lubricant in metal cutting, etc. It can also be used to synthesize the monomer of Freon and nylon, and can also be used to make chloroform and medicine. At present, it is clear that it has strong hepatotoxicity. Carbon tetrachloride poisoning is a legal occupational disease in China, which is mostly caused by inhaling its high concentration vapor in productive labor, and is characterized by central anesthesia symptoms and liver and kidney damage. Toxicity characteristics and hazards Carbon tetrachloride can be decomposed into carbon dioxide, hydrogen chloride, phosgene and chlorine when exposed to fire or hot substances. Carbon tetrachloride and its decomposition products can be absorbed into the body through respiratory tract and skin contact, and metabolize rapidly in the body. After inhalation, about 50% of them are discharged from the lungs in their original form, 20% of them are oxidized and transformed in the body, and the final product is carbon dioxide. Carbon tetrachloride vapor has a mild stimulating effect on the mucosa, an anesthetic effect on the central nervous system, and serious damage to the liver and kidney. Acute carbon tetrachloride poisoning: Inhalation of high concentrations of carbon tetrachloride vapor in a short period of time can quickly lead to coma, convulsions and other central nervous system symptoms, as well as pulmonary edema and respiratory paralysis. Inhalation of a slightly higher concentration can cause dizziness, headache, fatigue, staggering gait or mild disturbance of consciousness. Signs of liver and kidney damage were observed on the 2nd to 4th day of poisoning. In severe cases, ascites, acute liver necrosis, and renal failure occur. The main manifestations of chronic poisoning are neurasthenic syndrome and gastrointestinal dysfunction, and a few may have hepatomegaly and abnormal liver function. Poisoning causes and preventive measures Inhalation of high concentration carbon tetrachloride vapor is mainly seen in the chemical industry manufacturing dichlorodifluoromethane, trichlorofluoromethane and chloroform, etc. Due to the lack of good ventilation in the workshop and accidental leakage of equipment pipelines, a large amount of high concentration carbon tetrachloride vapor is inhaled in a short time. It can also occur when carbon tetrachloride extinguishers are used to extinguish fires in stuffy rooms, or when carbon tetrachloride is used to fumigate, dry clean, and scrub guns or machines. It is rare to take carbon tetrachloride liquid by mistake and absorb it through digestive tract or contaminated skin. When carbon tetrachloride contacts flame or hot metal,Medical Full Body Coverall, it is easy to decompose a large amount of phosgene and hydrogen chloride, and phosgene hazards can occur at this time. Precautions The production process shall be kept closed as far as possible, and the equipment shall be overhauled regularly to prevent leakage, leakage, dripping and leakage, and to prevent steam leakage into the air of the workplace. The production site shall be provided with good ventilation facilities. Operators must be specially trained and strictly abide by the operating procedures. It is recommended that operators wear direct gas mask (half mask), safety goggles, anti-poison penetration work clothes and anti-chemical gloves. Handle with care to prevent damage to packages and containers. Store in a cool and ventilated warehouse. Keep away from kindling and heat sources. The temperature of the storehouse shall not exceed 30 ℃ and the relative humidity shall not exceed 80%. Keep the container sealed and store it separately from oxidants, active metal powders and edible chemicals. Do not mix them. The storage area shall be equipped with spill emergency treatment equipment and suitable containment materials. Smoking, eating and drinking are prohibited on the work site. After work, wash the hands, face and other parts that may be contacted thoroughly. Store clothes contaminated by poisons separately and wash them for later use. Carry out pre-employment and regular physical examination, and those who suffer from neuropsychiatric system and liver and kidney organic diseases are not allowed to work. Strengthen the special storage of this product, and the label should be clear and eye-catching to prevent misuse and misuse. Emergency rescue and disposal principle Expand the full text First aid measures Quickly remove the poisoned person from the scene to a place with fresh air. Keep the airway open. Uch as dyspnea, oxygen. If breathing stops, give artificial respiration immediately. Seek medical treatment in time. In case of skin contact, immediately remove contaminated clothing and rinse skin thoroughly with soap and water. In case of eye contact, lift the eyelids and rinse with flowing water or normal saline. When ingested by mistake, drink enough warm water to induce vomiting. Gastric lavage. Seek medical treatment in time. Fire protection measures Carbon tetrachloride will not burn, but in case of open fire or high temperature, it is easy to produce phosgene and hydrogen chloride smoke with strong irritation and corrosiveness. Firefighters must wear filter gas masks (full face masks) or isolation respirators, wear full-body fire-proof and gas-proof suits, and put out the fire in the windward direction. Extinguishing agent: atomized water, Medical Quickly Delivery Antivirus Coverall ,KN95 Mask for Epidemic Prevention and Control, carbon dioxide, sand. Emergency treatment of leakage Emergency treatment: quickly evacuate the personnel in the leakage contaminated area to the safety area, isolate them, and strictly restrict access. Emergency response personnel are recommended to wear self-contained positive pressure respirators and protective clothing. Do not make direct contact with the leak. Cut off the leakage source as far as possible. Small amount of leakage: absorb with activated carbon or other inert materials. Large amount of leakage: build a dike or dig a pit for shelter. Spray water to cool and dilute the steam to protect the personnel in the open field, but do not spray water directly to the leakage point. Transfer to tank car or special collector by pump, recycle or transport to waste treatment site for disposal. Cases of poisoning Case 1 From December 25, 2004 to January 5, 2005, 39 workers in the inspection workshop of a weaving factory had different degrees of dizziness, nausea, vomiting, fatigue, loss of appetite and other symptoms, and were sent to the local health center for treatment. The on-site occupational hygiene investigation found that the factory used organic solvent "gun water" in the decontamination process of the inspection workshop, more than 30 employees were directly exposed to it, only ceiling fans were installed in the workshop, there were no ventilation and detoxification facilities, and the operators did not use effective personal protective equipment. The windows are closed due to the cold weather, and the working hours are 10 to 12 hours a day. The packaging container of "Gun Water" is marked as "1,1,1 trichloroethane, with a content of more than 96%." The daily consumption of the accident workshop is more than 10 liters. The sample of "gun water" was taken on the spot for composition analysis, and the results showed that it contained 57.4% carbon tetrachloride and 42% dichloromethane. The results showed that the concentration of carbon tetrachloride in the air of 10 detection points exceeded the national occupational health standard, and the highest concentration was 192 mg/m3, which exceeded the standard by 6. 6 times. According to the clinical manifestations, laboratory examination results and occupational health survey results of the workers, and according to GB242-2002 Diagnostic Criteria for Occupational Acute Carbon Tetrachloride Poisoning, 18 of the 39 workers were diagnosed as occupational mild acute carbon tetrachloride poisoning. Analysis of the causes of poisoning: At present, the market of cleaning agents is not standardized, the management is disorderly, the varieties are complicated, there are many "three noes" products, and the content of highly toxic chemicals is high. What's more, some people use foreign languages or codes to conceal the true names of chemicals, and there are no instructions and Chinese labels for toxicity. The main components of the so-called "gun water" in this accident are 57.4% carbon tetrachloride and 42% dichloromethane, while the factory container is labeled "1. The content of 1,1-trichloroethane is more than 96%, which misleads users and buries hidden dangers of accidents. In addition, poor equipment, imperfect detoxification facilities and lack of effective protective measures are the main causes of poisoning accidents. It is suggested that the factory should improve the production environment, separate the toxic and non-toxic processes in the production workshop, and reduce the hazardous area of poisons. Improve ventilation and detoxification measures, strengthen personal protection, and reduce the occurrence of occupational poisoning incidents. At the same time, efforts should be made to strengthen occupational safety and health education for workers and enhance their awareness of self-protection. Case II Patient 1: Male, 30 years old, ship engine worker, one day in the engine room of a small cargo ship, the ship engine was cleaned by spraying and scrubbing. The volume of the engine room was about 40 ITl3, and the ventilation in the cabin was poor. After half an hour, he felt dizzy, weak and uncomfortable. He went to the deck to ventilate and rest for about 10 minutes. After the symptoms improved, he returned to the cabin to continue working. About 2 H in total, more than 10 kg of carbon tetrachloride was used. Immediately, the patient found that the urine was brown and there was no blood clot. Nausea and vomiting occurred the next day, and self-perceived urination gradually decreased. On the evening of the third day, when the ship arrived at the dock, there was no urine in one day, and he was diagnosed with carbon tetrachloride poisoning, renal failure and uremia after visiting the hospital. Patient 2, male, 54 years old, was operated at the same time as patient 1, but the time was longer, about 4 hours in total, and the symptoms were similar to patient 1. He was also hospitalized and diagnosed with carbon tetrachloride poisoning, renal failure and uremia. The above two patients were discharged after hemodialysis and symptomatic treatment. Poisoning cause analysis: Workers did not understand the toxicity and hazards of carbon tetrachloride, did not pay attention to personal protection at work, worked for a long time without detoxification facilities, and absorbed a large amount of carbon tetrachloride through respiratory tract and skin,Antivirus Disposable Mask with CE Certificate, resulting in poisoning.

Original Title: New Rules for Wearing Medical Masks! The third edition of "Guidelines for the Prevention and Control of Novel Coronavirus" is coming Compared with the previous edition of the guide, what are the differences in the third edition and what are the main adjustments? On September 13, 2021, the National Health Commission issued the Technical Guidelines for the Prevention and Control of New coronavirus Infection in Medical Institutions (the third edition) (hereinafter referred to as the "Guidelines"), only five months after the publication of the second edition. The first edition of the guide was released on January 23, 2020. Compared with the previous edition, the new edition of the guidelines mainly increased the contents of "medical staff protection" and "closed-loop management of fever clinics and designated hospitals". The content structure has not been greatly adjusted, which is divided into four chapters: "overall requirements", "prevention and control strategies", "basic requirements" and "technical requirements of key departments and departments". Since this year, there have been many hospital infection incidents, requiring hospitals to refine the sensory control program. Since this year, hospital infection incidents have occurred in many places, which has sounded the alarm bell for hospital infection control. On January 19, the official website of the National Health Commission issued a circular on the inadequate prevention and control of COVID-19 in Gaocheng People's Hospital of Shijiazhuang City and Xinle Hospital of Traditional Chinese Medicine in Hebei Province, which included 14 positive cases, including a 70-year-old hospital nurse who was diagnosed. Problems such as confusion in hospital management, failure of health departments and local prevention and control command departments to perform their duties have been exposed, and Hebei Province and Shijiazhuang City have held relevant personnel accountable. At the end of July, a large-scale hospital infection broke out in the Sixth People's Hospital of Zhengzhou, and nearly 150 hospital staff and patients were infected. As a former "anti-epidemic star" of Henan Infectious Disease Hospital, Ma Shuhuan, Secretary of the Party Committee of the hospital,KN95 Mask with Fast Shipping, was dismissed after the hospital infection occurred. The Sixth Hospital of Zhengzhou is still in the period of recovery and reconstruction, and has not yet been opened. Expand the full text In September, the epidemic broke out again in Yangzhou, Jiangsu. Then came the epidemic centered on Putian City and Xiamen City in Fujian Province. Yesterday, the First Affiliated Hospital of Xiamen University announced that the nucleic acid test results of a logistics service staff of a third-party company in the hospital were positive. These incidents are reminding medical institutions to guard against weak links in the work of sensory control. Especially after the occurrence of large-scale nosocomial infection in Zhengzhou Sixth Hospital, the Joint Prevention and Control Group of the State Council issued three documents on strengthening the sensory control of designated hospitals, improving the sensory control mechanism of medical institutions, and strengthening the management of sensory control personnel in medical institutions within a month, which provided more norms for hospital sensory control work. The contents of these documents are also reflected in the guidelines released this time. The guidelines require strict implementation of the requirements of the above documents,free shipping disposable coverall, including equipping a team of highly professional infection control personnel according to the requirements; medical institutions should formulate detailed training programs for all staff of infection prevention and control in their institutions, and further strengthen the awareness that "everyone is a practitioner of infection control". To strengthen protection, some medical staff masks should be tested for tightness. "Proper Use of Personal Protective Equipment" is part of the "Essential Requirements" section of the guide. The content of the old guide is: Medical institutions should strengthen the management of personnel protection and reserve protective materials of good quality and sufficient quantity. Medical staff should correctly and rationally use medical surgical or medical protective masks, goggles or protective screens, gloves, isolation clothes or protective suit according to exposure risks and diagnostic and therapeutic operations, so as to ensure that personal protection of medical staff is in place. At the same time, they should guide and supervise patients and their accompanying personnel, as well as other personnel entering medical institutions to do a good job of personal protection. The latest edition of the guidelines adds a paragraph to the above content, requiring some medical staff masks to be tested for tightness: In isolation wards, fever clinics, nucleic acid sampling points, nucleic acid testing laboratories and other key places, medical staff who are more likely to come into contact with the novel coronavirus should strengthen protection and strictly implement the requirements of wearing medical protective masks. The personnel working in the fever clinic and the isolation ward of the designated hospital shall be tested for the suitability and tightness of the medical protective mask, and only those who are qualified shall be allowed to work; before entering the fever clinic and the isolation ward of the designated hospital, the tightness of the medical protective mask shall be tested. What should I do if the mask falls off carelessly in the polluted area? Guidelines require posting of disposal procedures For the contaminated areas of designated hospitals and wards for COVID-19 treatment, Virus Prevention Mask 3 Ply with Earloop ,Full Body Disposable Coverall, the old version of the guidelines requires that "the contaminated areas should be equipped with individually packaged personal protective equipment and occupational exposure emergency disposal boxes for emergency use", while the new version of the guidelines also requires that "the disposal procedures after respiratory occupational exposure (see Annex 4) should be posted in obvious places". Annex 4 reads as follows: Disposal process after respiratory tract occupational exposure 1. Respiratory exposure Close contact with patients diagnosed with COVID-19 due to lack of respiratory protective measures, damage to respiratory protective measures (such as loose masks, falling off, etc.), use of ineffective respiratory protective measures (such as use of masks that do not meet the requirements of the specification); contact with mouth and nose by hands contaminated by COVID-19, etc. II. Disposal Process (1) When occupational exposure to respiratory tract occurs in a medical staff, measures shall be taken immediately to protect the respiratory tract (covering the mask with the hand after the implementation of standardized hand hygiene or adding a layer of mask urgently, etc.), and the contaminated area shall be evacuated according to the prescribed procedures. (II) Pass through the unloading area in an emergency, and unload the protective equipment according to the requirements of the specifications. (3) Clean and disinfect the oral cavity or/and nasal cavity with clean water, 0.1% hydrogen peroxide solution and iodophor according to the situation, and leave after wearing a medical surgical mask. (4) Timely report to the director of the department concerned, the head nurse and the competent department of the medical institution. (5) Medical institutions shall organize experts to conduct risk assessment as soon as possible, including confirming whether isolation medical observation, preventive medication and psychological counseling are needed. (VI) Persons with high risk exposure shall be managed as close contact persons, and shall be isolated for medical observation for 14 days. (7) Fill in the occupational exposure record form of COVID-19 medical staff in time, especially the causes of exposure, and carefully summarize and analyze them to prevent similar incidents. Some fever clinics also need closed-loop management. The technical requirements for key departments and departments in the guidelines are independent. These key departments and departments are: fever clinics, emergency departments, departments/departments where patients need to remove masks when receiving diagnosis and treatment measures, hemodialysis centers (rooms), general wards (rooms), designated hospitals and wards for the treatment of COVID-19 infected persons, and COVID-19 nucleic acid testing laboratories. Among them, the new guidelines have greatly increased the contents of the two sections of "fever clinics" and "designated hospitals and wards for the treatment of novel coronavirus infected persons". For fever clinics, the new guidelines put forward more specific requirements for protection: medical staff entering and leaving fever clinics and observation wards should wear medical protective masks, work caps, gloves, boots or shoe covers (protective suit do not need to wear boots if they already have boots), wear isolation gowns or protective suit (observation wards should wear protective suit), and wear goggles or protective screens according to the operation of diagnosis and treatment. And part of the fever clinic staff to strict closed-loop management, this part is: reception entry, domestic high risk areas and focus on the isolation point of fever patients and other high-risk groups of fever clinics. All personnel in the isolation ward travel at two points and one line. In the old version of the guidelines, the isolation wards of designated hospitals were required to carry out closed-loop management, while the new version of the guidelines put forward one more point: "strict implementation". Specifically, during the working period, a single person will be arranged to live in a single room, and all personnel will travel between the station and the designated hospital at two points and one line, with fixed commuting vehicles, and no station will be arranged in the designated hospital. The new guidelines also specify the scope of "all staff" in the isolation wards of designated hospitals. Including: medical, management, security, cleaning, catering, medical waste collection and transportation personnel and other staff who directly or indirectly contact with COVID-19 infected persons (including medical staff such as imaging examination and closed-loop management personnel who provide services for COVID-19 infected persons). In addition, for designated hospitals, the new guidelines also have several provisions that the old version did not have: in principle, the reserve should meet the needs of designated hospitals to operate at full capacity for 30 days; fever clinics should immediately transfer new coronavirus infected persons to designated hospitals; For the management of accompanying and visiting, the expression of "in principle" has been deleted from the old version of "no arrangement for visiting and accompanying in principle", that is,KN95 Face Mask, "no arrangement for visiting and accompanying".

Original title: Origin of the "Five-storey Building" Prospecting Model The author searched many network and geological business books, watched the team annals of a unit, interviewed many geological predecessors, and found that they had a high evaluation of the "five-storey" model and the "five-storey + basement" as a prospecting model, which was praised as "the pioneer of the world's prospecting model". But the "five-storey" model is formed by summing up the laws of which mine? Which unit does it come from? Which geological senior engineers? When did this theory take shape? Network Books do not express it, and many people do not know it. The author recently solved this "mystery" from the letters of a senior geologist. The "five-storied building" model is derived from the vertical spatial variation law of veinlet belt deposit veins summarized by the geologists of the 909 Team during the exploration of the Piaotang Tungsten Mine in 1965, namely: downward variation: ① surface line vein belt — ② veinlet belt — ③ mixed belt of veinlet and large vein — ④ large vein belt — ⑤ single large vein (inserted into granite). According to the above law, the surface is a mineralization marker zone without industrial value and develops downward into a concealed industrial ore body, which broadens the horizon for geologists to prospect on the surface, and the summary of this law has enlightening significance for finding industrial tungsten ore bodies. "Five-layer zone division" ( "five-layer zone division" was first used by geologists of 909 Team) was put forward by two geological technicians of 909 Team, Zhu Yanling and Lu Xianrong, who wrote a paper on the law summarized in the prospecting practice of Piaotang Tungsten Mine. At that time, Piaotang Tungsten and Tin Mine was known as the treasure house of tungsten minerals and the model of the "five-storey" structure of tungsten mines, which was of great scientific significance to tungsten mineralogy and ore deposit science. In March 1966,Full Body Disposable Coverall, the State Science and Technology Commission held the "Gannan Tungsten Mine Geological Work Site Conference" in Dayu, Jiangxi Province. On behalf of the 909 Team, Wu Yongle (then the chief engineer of the 909 Team and later the vice-chairman of the Jiangxi Provincial Political Consultative Conference) read out the paper "Experience in Revealing the Distribution Law of Mineral Resources by Using the Method of Structural System Analysis". The representatives of 932 Metallurgical Geology Team of Guangdong Province also attended the meeting. Its representative also made a speech: According to the law summarized by the 909 team, they were guided to find the Meiziwo veinlet belt tungsten deposit in northern Guangdong (the straight line distance between the Piaotang Tungsten Mine in Dayu, Jiangxi Province and the Meiziwo Tungsten Mine in Shixing County, Guangdong Province was only 50 kilometers,Medical Disposable Coverall, and as early as before 1966, the two units had exchanged experiences), and the metallurgical geology of Guangdong Province changed the name of "five-layer belt division" to "five-layer building". Meiziwo Tungsten Mine is promoted as a classic mine of Guangdong's "five-storey building" model. Wu Yongle, the representative of the 909 team, read out the first paper at the "Gannan Tungsten Mine Geological Work Site Conference", which became the central paper of the whole conference. The representative of the 932 Metallurgical Geology Team of Guangdong Province only made an oral speech. The representative also made it clear at the meeting that it was inspired by the experience of the 909 Team that he found the Meiziwo Tungsten Mine in Shixing, Guangdong Province. In that year, Meng Xianmin, Yu Jianzhang, Sun Yunzhu, KN95 Face Mask with Five Layers ,CE Certificate KN95 Mask, Xie Jiarong, Guo Wenkui, Xu Keqin, Wu Leibo and Ma Xingyuan, who are well-known in the geological circles of the whole country and even the world, came to attend the "Gannan Tungsten Mine Geological Work Site Conference". At this meeting, the "five-storey" model was formally confirmed by the geological community and formally formed. After the conference, the Ministry of Geology submitted five papers to the State Council under the general title of "Discovery of Muziyuan Concealed Tungsten Deposit", including "Experience in Revealing the Distribution Law of Mineral Resources by Using the Method of Structural System Analysis" and "Prediction of Muziyuan Concealed Granite", which were listed as one of the major scientific and technological achievements of the People's Republic of China in 1965. Fortunately, geologists in southern Jiangxi have successively discovered six similar small and medium-sized concealed and semi-concealed tungsten deposits in Dayu Jiulonao, Yudu Shangping, Dayu Shilei, Chongyi Gaocha and Xin'anzi areas by using the "five-storey building" model, and the prospecting results are amazing. After the reform and opening up, the state attaches great importance to academic theory, and there are two voices in the geological circles: Jiangxi Geological Bureau calls it "five-layer belt division", and Guangdong Metallurgical Geological 932 Team calls it "five-layer building". To this, Zhu Yanling talked about his own views: "To put it nicely, a son was named by his father and named by his mother.". To put it bluntly, it is to steal the rules summarized by others and give them another name. ” Nearly 50 years have passed, Zhu Yanling, who summarized and put forward the "division of five layers and zones", Wu Yongle, who read the paper at the "Gannan Tungsten Geological Work Site Conference", and Miao Shuping, Li Yidou, Li Chongyou and other geological predecessors who have made outstanding contributions to the search for tungsten deposits have all passed away. They have made great contributions to the cause of geology and mineral resources of the motherland and mankind, and the model prospecting theory they have created is like the sun and the moon shining together. So far, they have been guiding the new generation of geology to make breakthroughs in prospecting. Happily, after half a century, generations of geologists, on the basis of summing up the "five-storey" prospecting model of their predecessors and according to the new progress of deep prospecting in recent years, have expanded the "five-storey" model to "five-storey + basement". As a prospecting model,Medical Full Body Coverall, "five-storey building + basement" is not only suitable for the southern Jiangxi-northern Guangdong area, but also for many quartz-vein-type tungsten deposits, tin-polymetallic deposits and other types of minerals and deposits throughout the country. This model is a great contribution made by Jiangxi geologists to the world geological community. Return to Sohu to see more Responsible Editor:. zjyuan-group.com

Original title: As the epidemic continues, medical staff must master the graded protection standards. Prompt: "Medical Law Online" ↑ Easy to follow us Let the Law Know More About Medical Care Let Medical Care Know More About the Law In the process of medical practice, medical staff need to protect themselves according to different diseases and different modes of transmission, and at the same time, they need to ensure the safety of patients to avoid two-way transmission, so medical workers need to do a good job of corresponding protection to block the occurrence and development of diseases. Move forward and implement standard prevention and graded protection standards. 01 Standard prevention knowledge points Standard precautions mean that the patient's blood, body fluids, secretions, and excretions are considered to be infectious and need to be isolated, regardless of whether there is obvious blood, contamination, or contact with incomplete skin and mucous membranes. Precautionary measures must be taken in case of contact with the above substances. 1. Standard precautionary principle It is the basis of medical staff protection and is applicable to all medical staff in different working areas and posts. 2. Standard Prevention Core It refers to a group of prevention and control measures taken to reduce the risk of nosocomial infection based on the principle that the patient's blood, body fluids, secretions (excluding sweat), excreta, incomplete skin and mucosa may contain infectious factors. Including hand hygiene, use of personal protective equipment, cough etiquette and so on. 3. Standard precautions include the following ： (1) The blood, body fluids, secretions, and excretions of all patients are considered infectious and must be isolated, and protective measures must be taken for contact with substances with obvious blood, body fluids, secretions, and excretions, or contact with incomplete skin and mucous membranes. (2) It is necessary to prevent the spread of blood-borne diseases and the spread of non-blood-borne diseases. (3) Two-way protection is emphasized. It is necessary to prevent the transmission of diseases from patients to medical staff, and to prevent the transmission of diseases from medical staff to patients. 4. Specific measures of standard prevention include ： (1) Hand cleaning and disinfection is an important measure to cut off contact transmission. Hand cleaning and disinfection should meet the requirements of the Hand Hygiene Standards for medical staff. (2) Gloves should be worn when contacting blood, body fluids, secretions, excreta and other substances and articles contaminated by them. (3) Wash hands immediately after removing gloves. (4) When the work clothes, face and eyes of medical staff may be splashed by blood, body fluids, secretions and other substances, they should wear surgical masks, protective glasses or masks, and wear isolation clothes or waterproof aprons. (5) When handling all sharp instruments, special attention should be paid to prevent being stabbed. (6) Correct disinfection and sterilization measures shall be taken for medical devices and appliances used by patients. 02 Expand the full text Exposure risk classification of medical staff 1. Exposure Risk Classification Standard Take protective measures of droplet isolation, contact isolation and air isolation, and take appropriate personal protection according to different exposure risks: (1) Low risk: indirect contact with patients, such as guidance, inquiry, general outpatient and ward rounds, etc. (2) Moderate risk: direct contact with patients, such as physical examination, puncture, injection, etc. (It is recommended to have physical examination with mucous membrane or body cavity contact, and invasive operation without the risk of body fluid splashing, such as ultrasound-guided breast puncture, deep vein puncture, etc.). (3) High risk: operation or surgery with splashing of blood, body fluid, secretion,3 Ply Disposable Protective Face Mask, etc. Or that may produce aerosol, such as throat swab collection, sputum suction, oral care, tracheal intubation, non-invasive ventilation, tracheotomy, cardiopulmonary resuscitation, manual ventilation before intubation, endoscopy, etc. 2. Protection selection based on risk level (1) Low-risk operation: work clothes or wear isolation clothes, surgical mask, work cap and hand hygiene. (2) Medium risk operation: work clothes plus isolation clothes, medical surgical mask/medical protective mask, work cap, protective face screen/goggles, gloves and hand hygiene.

Original Title: Finding Water and Drilling Wells for Poverty Alleviation in Southern Jiangxi: Case Analysis and Process Record (Part II) Part 1 Indoor comprehensive research and judgment, accurate well determination in the field Click to Read: Gannan Poverty Alleviation Water Search and Well Drilling: Case Analysis, Process Record (Part I) Part 2 Fast drilling verification and intelligent water pumping First, rapid drilling verification, chopsticks inserted tofu 2017.1.8, Sunny, Sunday At the foot of Yangshan Mountain, the national flag rises in the west of Xixia Village. At 16:58, the first well (xgzk1) in Xingguo County, Gannan Poverty Alleviation and Water Exploration of Shuihuan Center was drilled, with a designed hole depth of 120 m. Expand the full text At 18 o'clock, the footage was 7.5m, the loose layer was penetrated, the bedrock was entered, and the 325mm retaining pipe was lowered for 8m. In the morning, go to the construction site and make disclosure with the second drilling team. At 4:30 in the afternoon, the drilling rig was ready. At 17:00, the drilling was spudded. The bedrock was found at 7.5m, and the 8m long, 325mm steel retaining pipe was lowered. The drilling speed is so fast. Photo 23, 24 Open the first drill, and the machine is roaring. Implementation of hydrogeological drilling 1. Device configuration Drilling rig model: SL-800 A crawler power head drilling rig. Type of derrick: mast type. Power machine type: diesel engine. Other equipment: DWQ1200 XXH air compressor, submersible pump, ultrasonic flowmeter, 50 kw generator set, automatic recorder for pumping test, etc. 2. Drilling technology and drilling parameters (1) Drilling process Pneumatic Dth hammer is used to drill XGZK01 hole, Ф350mm Dth hammer bit + TH10 impactor + 114 drill pipe is used for opening, Ф305mm Dth hammer bit + TH8 impactor + 114 drill pipe is used after reducing, reducing depth is 7.50 m, and final hole depth is 120.00 m. (2) Drilling parameters Pneumatic Dth hammer is used for full drilling with positive circulation. The technical parameters are as follows: ① Air volume: 34m 3/min. ② Wind pressure: 3.3 MPa. ③ Weight on bit: 16-18k N. ④ Speed: 20 ~ 50r/min. 3. Coring One rock debris sample is taken every 4.5m in the whole hole, and 35 rock debris samples are taken in total. The cores taken shall be arranged in turn, filled in and labeled in time, and recorded by hydrogeologists in time. In the process of logging, in addition to the description according to the general hydrogeological requirements, the geologists have made a detailed study and description of the physical properties of the rock strata. In particular, the minerals in the rock formation are described in detail, such as the main mineral components and their contents, sand, clay, powder and organic matter contents. For sandy and gravelly soil, the contents of sand and gravel are distinguished, and the roundness of gravel is described; for clayey soil, the color, natural state, clay powder content and water content of the sample are described. In addition, the rock strata exposed by drilling are described and divided in detail to determine the lithology of aquifer, aquiclude and basement. 2017.1.9 The first drill likes to come out of the water. Look at my acupoint work. With the mission of poverty alleviation, the Ministry and the Bureau send warm care to the old liberated areas; sweat turns into spring water and moistens the red earth. After 8 hours of down-the-hole hammer drilling, the first drill in Xingguo County of Gannan Poverty Alleviation and Water Exploration of the Water Ring Center successfully produced water, with a rough water volume of 30m ³/H. This once again shows the technical strength of water exploration in the bedrock mountain area of Shuihuan Center, the synergistic advantages of multi-professional and multi-method integration in tackling key problems, and the "acupoint" magic of the iron triangle team in water exploration. The No.1 well is located in the determined Cretaceous glutenite water exploration target area. The drilling equipment entered the site on January 8, 2017 and spudded at 16:58 on the same day. Bedrock is found in the shallow loose layer at 7.5m, and a small amount of shallow water is found at 14.5m; quartz sandstone is initially found when drilling to 102.5m, and the fault is exposed, with a water yield of about 5m ³/H, above which are purple argillaceous siltstone, sandstone and mudstone; quartz sandstone is found when drilling to 129m, with a water yield of 8 m ³/H; When drilling to 133.5m, the granite formation is exposed, and the water volume increases to 10m ³/H; when drilling to 135m and 139m, the water volume increases to 30m ³/H, and the water yield is the highest in this area; when drilling to 155.5m, the final hole is completed. The stratum exposed by the borehole is basically consistent with the stratum predicted by the previous team, and a new breakthrough has been made in the understanding of the regional geological water-rich law, which provides a new direction for water exploration in similar areas in the future. The preliminary investigation shows that the water required for drinking water and tobacco field irrigation in Qixia Village is about 10m ³/H. However, the local stratum has poor water-rich conditions and complex structure. The township government and the masses have doubts about whether an ideal water source can be found in the local area. In addition, the local economic conditions are poor, and no deep water drilling has been carried out. The successful implementation of the borehole basically met the water demand of the local people, and also played a good demonstration role for the local search for follow-up water sources. Arriving at the construction site at nine o'clock, the drilling speed of the down-the-hole hammer was really fast. In the Cretaceous sandstone and mudstone formation, it took almost ten minutes to drill a 4.5m drill pipe at the beginning. To 50m, the red mudstone was blown up, 60m or 70m, red soil, 80m, red soil, 84.5m, still the same, we rushed back to the county for dinner, we were a little uneasy, although we did not say it. More than two o'clock, the phone told the water, everyone rushed to get on the car, on the way, everyone's words obviously increased. He got out of the car and met the drilling personnel. He said that there was estimated to be ten cubic meters of water. In front of the drilling rig, I asked the captain and learned that there was water at 102.5m. I checked the rock debris and found that it was a layer of crushed coarse sand. I judged that it was granite weathering crust or fault zone. With the increase of depth, the water volume was increasing. Li Gong proposed to deepen from 120m to 140m, and to 129m, the water volume suddenly increased, 20 cubic meters, 30 cubic meters. It continued to surprise people's hearts. We returned at six o'clock and told them to continue to deepen to 155m. Everyone rejoiced, went to the kitchen on the 7th, added food, served wine, and drank a little wine. All of a sudden, everyone's pressure was relieved and they had a good time. Tell the leaders of the center that they are as happy as we are. Tell the leaders of Xingguo County to visit you at the scene tomorrow afternoon. Photos 25, 26 and 27 show that the first borehole successfully produced water, which verified the geological and geophysical exploration results. 2017.1.10, sunny, windy The drilling rig is transferred to the new well location, and the wind spreads the red flag hunting sound. After xgzk1 hole in Xixia village, Xingguo county successfully produced water yesterday, the drilling rig was transferred to xgzk2 hole today and is now ready to start drilling tomorrow. The geological conditions of this hole are similar to those of the hole No.1 just completed, and it is also a secondary structure of the nearly north-south compresso-shear fault in front of the Yangshan Mountain, with a design hole depth of 120m. This afternoon, Wang, deputy head of Xingguo County, visited the comrades of the project team at the construction site. After the project team reported on its work and achievements, he praised the national team for achieving such rich results in such a short period of time. At the same time, he inquired in detail about the amount of groundwater, the development and utilization plan and the impact of exploitation on the environment. I also introduced the legend of Zhu Li. After listening to the introduction at the No.2 hole, he went to the No.1 hole for investigation. He instructed the cadres of Baocun Village in the township to consider the funds for drinking water projects and bring the benefits of wells into full play. At 17:15, the work summary meeting invited Zhu and Li to review and analyze the objectives and achievements of the previous work deployment, and also put forward suggestions for future work. According to the observation, the buried depth of water level of xgzk1 hole rises from 14.9 m at 8 o'clock to 13.7 m at 16 o'clock today. Simple Hydrological Observation of Hydrogeological Drilling In the process of drilling, the aquifer was found in time, and the hydrogeological problems such as water abundance of the aquifer were preliminarily determined. It mainly observes the groundwater level, water temperature, water gushing and leakage. In addition, detailed observation records shall be made for the drilling conditions (such as drill dropping, drill sticking, drill burying, hole wall collapse, sand gushing, gas escape, etc.) and the positions of layer change and hole change. Measure the water level after lifting the drill and before tripping in. During the drilling of XGZK01 hole, it was slightly wet at 12.00 m, a small amount of water was seen at 16.50 m, continuous water was seen at 25.50 m, no water leaked during drilling, water burst at 103.00 m, the water inflow was about 20.00 m ³/H, the water volume increased at 135.00 m, and the visual water volume was about 35.00 m ³/H. Photo 28 The commandos took a group photo. Photo 29 Water level observation of No.1 hole Photo 30 No.2 hole drilling machine in place 2017.1.11, Wednesday, light rain Xingguo, light rain. In the morning, the first group of members of the Gannan poverty alleviation and water search commando team withdrew from the base camp and set off. Rain, farewell? Retain? Rain is the accumulation of water vapor in the first well? Happy and grateful for the liberation to see the light of day and serve the world? Wake up at six o'clock and revise the special report. Before seven o'clock, they went downstairs to see Li, Zhu, and Xiao Wang off to Nanchang and then returned to the insurance high-speed railway. At 7:20, the two drivers, Li and Yang, followed by Geophysical Prospecting Company and Yang, returned to the insurance. After getting on the bus with breakfast, he and Liu went to the Ningdu Mining Administration Bureau to communicate about the problems in the land quality investigation area of another project, and rushed back to Xingguo at 12:20. The No.2 hole was drilled at 8 o'clock,Mining Drilling Equipment, with a footage of 50m at noon and a water yield of 3m ³/H at 2 o'clock. After half an hour, the water yield suddenly increased to 50-70 m ³/H. I will no longer change the special report, and I will write it together after determining the approximate water output of No.2 hole. When I arrived at the construction site at 3 o'clock, I saw that the smoke field covered with film was soaked in water, and it was a vast ocean. The captain estimated that the current water volume was 100m ³/H. Because of the large amount of water, the drilling speed is affected. By 3:30, the footage is 97m, and the estimated water volume is conservatively 70-80m ³/H. Far more than we expected. Report to local leaders and central leaders by phone or SMS. The water volume is too large. The pipe of 219 mm originally planned is a little thin and needs to be increased to 245 mm. The pump of 50 square meters is also small and needs to be replaced with a large pump. The captain was happy, General Manager Liao was surprised, and Manager Hu smiled. In the evening, Xingguo TV broadcasted the news that the county magistrate Wang went to the construction site. Extra: "Yin River" found, found!!! Hole xgzk2 in Xingguo county was drilled at 8 o'clock today. At present (note: 15:30), the drilling depth is 97m, and the water output during the drilling process of the down-the-hole hammer is estimated to be 70-80m3/H, which is twice that of hole 1? Twice..! It is 20 times of the maximum water yield (102m 3/d per day) of the known boreholes in the Cretaceous strata of the Xingguo Red Bed Basin! It's so big that it affects the drilling speed! During the period of field investigation and geophysical prospecting, an old man told us that there was a Yin River flowing through Yangshan in the west of Xixia Village. Today, we have found, we have found, that the Yin River is this water-rich tectonic zone, this is no longer a legend! The Iron Triangle Team of Water Search in Bedrock Mountain Area casts a new legend in the poverty alleviation and water search in southern Jiangxi! Have a long tassel in hand, today again bound black dragon! Technical Summary of No.2 Hole Gannan Poverty Alleviation and Water Exploration Project reported another success. During the construction of XGZK2 borehole, the water yield was roughly measured to be more than 80m ³/H. Combined with XGZK1 borehole, the local villagers' traditional understanding of "no available water source in Qixia Village" was completely overturned, which provided a strong guarantee for local economic development and industrial planning. GZK2 borehole encountered water at 80.5m, the lithology is Cretaceous gravel layer, the water volume at 84-85m increases sharply to 80m ³/H, the lithology is granite, sharp and poorly sorted quartz debris can be seen in the rock debris, and there is drill dropping in this section during drilling. It is concluded that 84-88 m is the structural fracture zone, which is the groundwater catchment corridor and the main runoff channel, and can be called the "Yin River" of the local villagers' legend. According to the interpretation results of remote sensing and geophysical exploration in the early stage, the logging information of the cuttings taken is analyzed, the 107 m variable diameter of the borehole is designed, and the final hole is expected to be 134 m, and the following two understandings are obtained: 1. Secondary structural fracture zone and its intersection zone of the main controlling structure in the north-south direction It is the main occurrence area of vein groundwater. 2. Contrast Borehole XGZK1 shows that the water production horizon moves upward and the water volume is more abundant, which reveals that the well location is close to the water-blocking structure under the new house and is located in the mesh area where the secondary structure intersects with the main control structure, which is a typical type of water storage structure on the edge of the mountain basin. Photo 31-32: Flooded tobacco fields 2017.1.12, Thursday, light rain Two demonstration wells have been drilled by down-the-hole hammer drill, and the second drilling team is awesome! Today, we detect the well, observe the water level and prepare for the pumping test. In the morning, the special report on the results of poverty alleviation and water search was revised and issued. Then he went to the construction site, and when he got there, he had drilled 120m and reached the quartzite vein. Li suggested to drill another 10m in order to find out the situation of the vein. He proposed to drill three drill pipes, 13.5m. I arrived at the construction site again before two o'clock in the afternoon, and I had finished three in an hour, with a total of 133.5m. In the rain, the drilling rig is shut down, and the pipe is pulled out for fear of slipping,dth drill bits, which is unsafe. The pipe is pulled out after the rain stops. During the drilling of XGZK02 hole, the rock at the hole depth of 79 m was relatively wet, and water gushing was found at 80.50 m. The water gushing continued after the rod was added, with a water inflow of about 80 m ³/H, and water leakage was found at 120 m. At the same time of abundant water in No.2 hole, the water level of No.1 hole continued to drop by more than 30 meters, and the water level at 14 o'clock was 40.58 m deep in No.1 hole and 69 m deep in No.2 hole (7:20 in the morning, 21.14 m), which indicated that the two were related, or directly related, or the recharge area was one. When selecting water pumps, it is necessary to conservatively select a small pump capacity to avoid excessive exploitation, after all, the area of the recharge area is small. The 245 mm well pipe was originally planned to be purchased. On the one hand, because it is a non-national standard pipe, the supply cycle is long. On the other hand, in view of the large water level drop, the pipe diameter is returned to 219 mm, which can ensure that the pump with a diameter of more than 50 m ³/H can not be lowered due to the large diameter of the pump head, so as to limit the exploitation. Logging will be started for No.1 hole this morning, and No.2 hole will be logged tomorrow after completion. The pumping test of No.1 hole will start tomorrow, and we need to wait for the water level to basically return to the initial level. The pump capacity of No.1 hole is 50m ³/H, and that of No.2 hole is 80m ³/H. After well completion, the pump capacity of No.1 hole is 20m ³/H, and that of No.2 hole is 50m ³/H. Photo 33 Rain Logging Photo 34 Water Level Observation 2. Intelligent pumping test to pull out rare lithium mineral springs 2017.1.13, Friday, light rain, 5-8 degrees Prepare for pumping test In the cold rain in winter, in the muddy water with sticky shoes, under the cloudy twilight, prepare for the pumping test. After getting out of the water and cheering, complete the follow-up work according to the specifications. Follow the headlights and go back. Thank you, thank you, the rain did not fall during the field investigation and geophysical prospecting work, otherwise the construction period would be longer. I miss the sunshine at that time, although the temperature reached 24 degrees at noon for four or five consecutive days, which blackened our skin. Pray for a sunny day, even if the high temperature comes again, as long as the mud is dried; pray for no rain, even if it is cloudy, windy and cold, as long as it is convenient to work, complete the task as soon as possible, go home for the New Year as soon as possible, and give it to the people to use as early as possible. When I went to the construction site in the morning, the second team was carrying a small drilling rig. At 5 p.m., the pumping equipment was ready. After arriving at the site, it was found that the height of the outlet made of drill pipe above the ground was too small to bind the ultrasonic flowmeter. The pumping test cannot be started tonight due to the repair of the motor failure. Geophysical Logging Integrated geophysical logging mainly includes tests of 3 laterolog resistivity (or apparent resistivity), natural potential, artificial gamma, natural gamma, acoustic velocity, well fluid resistivity, well temperature, hole diameter and hole deviation. According to integrated geophysical logging interpretation, XGZK01 hole mainly has three aquifers: 103.00-103.65 m, 104.65-105.00 m and 141.25-143.25 m, all of which are tectonic fissure water. According to comprehensive geophysical logging interpretation, XGZK02 hole mainly has two aquifers: 82.55-83.35m and 104.05-104.35m, both of which are tectonic fissure water. Pumping test 1. Pumping equipment 150Q150-60/12 submersible pump, FLUXUS F601 ultrasonic flowmeter, triangle weir box, water level meter, etc. 2. Test method The single-hole steady flow method is used for the test, and the test is carried out according to 2-3 drop paths from large to small. 2017.1.15, Sunday, December 18, cloudy day Pumping starts at thirteen o'clock, the water volume fluctuates between 27-31 m ³/H, and the water temperature is 25 degrees. After forty minutes, the amount of water decreased significantly and the water level rose. Smoke was seen coming out of the wellhead, and the generator was shut down immediately. It is judged that the cable is overloaded and burnt. Comprehensive analysis shows that the cable is a little thin and needs to be replaced. Communicate with the person in the equipment department and send a large cable. In this way, it is a big project to raise the water pump under 100m. Time, time.. 2017.1.16, Monday I contacted the second team at seven o'clock in the morning. I didn't finish it last night. It's estimated that it will take an hour to get off the pump today. We had dinner at half past seven, and then we went there together. When we got there, we saw that the pump was still running, one drill pipe after another. At half past three in the afternoon, there were still some problems after the generator was turned on. Considering the time problem, I decided to rent the generator. We rushed back to the county town for dinner and returned to the construction site after dinner. The rented generator arrived at the construction site and was tested. The water output was 45m ³/H. At 10 o'clock, the water was pumped at 32m ³/H. The water level could not be measured. There was no problem with the water gauge. It was suspected that the probe was stuck in the middle when it was lowered. As the self-gauging water level gauge was placed at the position of 80m, it was feared that the drawdown would exceed the depth, so the water yield was adjusted to 25m ³/H, and returned after basically stabilizing at 72m at 11:00, and arrived at the base at 11:30. A tense, hurried day. 2017.1.17, Monday, light rain, 8-12 Go to eat at half past seven, and then go to the construction site. Water samples of drinking water, mineral water and sanitary indicators are taken and sent to Nanchang regularly. Subsequently, Wang and Gong returned to their residence to put the annual implementation plan into the Ministry of Land and Resources. The reconciliation workers continued to observe the pumping situation. At 11:40, the frequency conversion is started, gradually changing from 46 to 41.5 Hz, and the water yield is basically stable at about 15m ³/H. The technicians and leaders of Gannan Geological Brigade went to the construction site to inspect the down-the-hole hammer drilling technology. Technical summary: Dth hammer drilling, over 100 meters in a day After nine days of rapid determination of five alternative well locations, the pneumatic down-the-hole hammer positive circulation drilling technology was used, and the cumulative drilling time was 28 hours, and two boreholes with a diameter of 305 mm and a depth of 155.5 m and 133.5 m were completed. Down-the-hole hammer drilling technology is powerful, the second team of brothers are capable and able to bear hardships, cattle! Hole 1: 155.5m, dth drilling hammer ,dth button bits, 0-7.5m loose layer, 7.5-129m Cretaceous argillaceous sandstone, 129-155.5m tectonic zone and granite. The drilling was spudded at 16:58 on January 8, stopped after the bedrock was seen, and the 8m retaining pipe was run in and finished at 18:00; the drilling was started at 8:00 on January 9 and completed at 18:30; the drilling time was 11.5 hours. Hole 2: 135.5m, 0-4m loose layer, 4-84m Cretaceous glutenite, 84-135.5m tectonic zone and granite. On January 10, the drilling rig was transferred to No.2 hole; on January 11, the drilling was spudded at 8 o'clock with 107 m diameter change and finished at 18:30; on January 12, the drilling was spudded at 8 o'clock and completed at 14 o'clock; the drilling time was 16.5 hours. Crawler drill with full hydraulic power head is selected for this drilling; the diameter of Dth hammer bit is 305 mm, and it is equipped with medium and high pressure impactor, and the diameter of drill pipe is 114 mm; the air compressor has an air volume of 35 m ³/min, and the air pressure is 3.1 MPa. The choice of Dth hammer drilling is based on three considerations. First, the purpose of drilling is mainly for poverty alleviation and water supply, which needs to be put into use before the seasonal spring drought, and the time is tight. Secondly, the stratum lithology of the working area is Cretaceous argillaceous sandstone and Caledonian granite, which is relatively simple. Thirdly, the lithology and water intake section can be divided by the combination of cuttings fishing logging and logging. Pneumatic Dth hammer positive circulation drilling is a traditional process method of Dth hammer. The working process is as follows: compressed air is transmitted to the down-hole hammer through the inner hole of the drill pipe to drive the down-hole hammer to do work; the discharged waste gas is discharged through the exhaust hole of the drill bit, washes the hole bottom, cools the drill bit, and carries rock debris to return to the surface along the annular gap between the hole wall and the drill pipe. It is suitable for hard bedrock formation, Quaternary cemented and semi-cemented formation, and gravel formation, especially for areas with water shortage or water supply difficulties, and is often used for non-coring drilling. Its advantages are high drilling efficiency, low cost, no pollution to water-bearing layer, easy flushing and high water output. Photo 35, 36 Dth Hammer Drilling Photo 37 People digging earth wells at the mouth of the ditch Photo 38 Banana 2017.1.17 Time is easy to throw people, red plantain, green plantain. 2017.1.18 Start pumping of No.1 hole in the morning. In the evening, the problem of making the steel bar triangle, which acts as a centralizer for the lower tube, was solved, and General Manager Liao came to do it himself. The pumping equipment has been assembled at No.2 hole, and the drilling tower to be lifted will be erected tomorrow. Time, time! Pumping test start intelligent mode The frequency conversion cabinet regulates and controls the drawdown of three falling distances, and the equipment automatically records and monitors the water level and quantity. In the specification of 1:50000 hydrogeological survey, the steady flow pumping test "should be carried out three times of water level drawdown, the maximum drawdown value should be determined according to the hydrogeological conditions and the capacity of pumping equipment, and the other two drawdown values should be 1/3 and 2/3 of the maximum drawdown value respectively". The so-called hydrogeological conditions are similar to the groundwater type, water-bearing rock group and the estimated water yield of trial pumping, for example, "when three drop pumping tests are carried out, the maximum drawdown phreatic water should be equal to 1/3-1/2 H (H is the height of the water column from the bottom of the aquifer).". For incomplete wells, the water column height is calculated from the bottom of the hole); for confined water, it should be as far as possible to the top of the aquifer " (Hydrogeology Manual (Second Edition), p. 450), which is the basis for selecting the appropriate pump type. The capacity of pumping equipment should match the estimated water output, instead of using existing pumps to pump water regardless of the water output, regardless of the size of the pump, resulting in too small drawdown, or even converting the maximum drawdown of 1 meter into the unified drawdown of 10 meters, resulting in data distortion and misleading results; For particularly water-rich areas, the pump type close to the estimated water yield should also be selected as far as possible. The adjustment of the tertiary drawdown value is based on the control of the water yield. At present, there are three methods. The first is to install a "tee" at the water outlet of the wellhead to adjust the water yield and control the dynamic water level. The second is to replace the pump with different water yield to pump water, so that the pumping time is prolonged, especially in the case of a deeper hole; Thirdly, the frequency conversion cabinet is used to adjust the frequency of the current to control the water output of the water pump, which can conveniently realize three water level drawdown pumping. During the preparation of the pumping test, considering the estimated water yield of 30m ³/H for No.1 hole and 70-80m ³/H for No.2 hole during Dth hammer drilling, pumps with water yield of 50m ³/H and 60m head and pumps with water yield of 80m ³/H and 100m head were prepared respectively, and the frequency conversion cabinet was used for three drawdown pumping tests. In order to ensure the accuracy of the measured data and parameter calculation of the pumping test, the water level at the outlet of the weir box is measured manually to determine the water yield, and an ultrasonic flowmeter is bound on the outlet pipe for automatic measurement, real-time display and data storage; and a wireless self-gauging water level meter is placed for observation and data storage while the water level is measured manually at a specified time interval. The pumping visualization monitoring technology and equipment developed by the Water Ring Center have realized the automation and visualization of water level and water temperature monitoring during the pumping test, facilitated the real-time monitoring and control of the pumping test, reduced the labor intensity of the previous pumping monitoring equipment which needs to be attended, avoided the error of manual operation, and improved the observation accuracy; The equipment includes a wired self-gauging water level gauge, a computer and a water level and temperature real-time display software, and the data sampling time interval can be set freely; the waterproof performance of the underwater cable connector reaches 4Mpa, and the underwater cable connector can work normally under 400m water. The system has been successfully developed in the hydrogeological survey project of Heihe River Basin in Gansu Province, and has been applied in the stratified pumping test, which has achieved the effects of ensuring quality, improving work efficiency and optimizing working environment.

More than half of No.1 hole is under the pipe, and No.2 hole starts pumping test. In order to ensure the service life of the water supply well and serve the water supply needs of the people in the old area for a long time, after the pumping test of No.1 hole, the well pipe will be put down today. At the same time, the pumping test of No.2 hole was prepared. After a day's efforts, the pumping test was finally started at 19:45. Victory is in sight.. I hope everything goes well! In the morning, I heard from Manager Hu that refueling in the morning could complete the construction of the drilling tower. After dinner, the reconciliation workers went to the construction site. First, I went to No.1 hole to see the progress of the pipe, then to No.2 hole to see the construction of the drilling tower, only to see blue arm-thick iron pipes scattered on the slope beside the borehole. It is planned to use a crane to install it. In the morning, I found three cranes, but they all said that they could not get in because of the muddy rain. When I found the fourth one, I agreed to come here. It is suggested that the drilling rig should suspend the pipe running in hole 1 and run the pump in hole 2 first. At half past three, we set out for the scene and saw that the drilling rig was still running down the pipe. Manager Hu was preparing the generator and assembling the water pump while waiting for the drilling rig to come. Around 4:30, the drilling rig was transferred. The pump began to run, and by seven o'clock, the pump was in place. Then he began to adjust the weir box, and Gong, Wang and Fu, who went back to see the house, rushed back to install the ultrasonic flowmeter and measure the water level. The pump depth is 96.5m, the water inlet position is 95.5m, and the water level gauge position is 89.5m. At 7:45, the pumping officially begins. The current frequency of the frequency conversion cabinet was adjusted to 47Hz, and the maximum water output was 120m ³/H at the beginning, and then it dropped. At 8:30, it was roughly stable at 96m ³/H, so we went back to the county for dinner. Turning to the main road of the county town, the traffic police stopped our car and checked drunk driving. We joked that we hadn't had dinner yet. We will discuss the matter of going home during the meal, and we will see the pumping test tomorrow morning. Return to the station after eating at 9:30; eat at 7:00 tomorrow morning, collect water samples, and send them to Nanchang. On the way back, Wang Cha said that the high-speed railway from Nanchang to Baoding on the 24th was still available. Is it decided first. Considering the normal progress, it should be OK. After arriving at the station, it was found that there was a ticket from Jinggangshan Airport in Ji'an to the Capital Airport on the 24th, which took off at 12 o'clock and arrived before 3 o'clock. The fare was lower than the high-speed railway, so reconciliation and Wang tentatively booked the flight. The other four are back in two cars on Sunday morning. At 10:45, the water volume and water level of the pumping test continued to drop, the water level dropped to 82 m, and the water volume dropped to 60 m ³/H. Gong suggested using a frequency conversion cabinet to reduce the amount of water, and the result of our discussion was to wait another half an hour to see the changes. Time in the difficult driving, 10 minutes to measure a data, 11:20, the water level is roughly stable, continue to pump. At twelve o'clock, the amount of water dropped and the water suddenly became turbid. Discuss the countermeasures together: one is to stop pumping, worrying about the collapse of the well wall; the other is to reduce the water yield. It is judged that the turbid water is due to the falling off of the Cretaceous red bed after the water level drops and the pressure of the well wall loses balance, which will not collapse the hole, and at most it will be difficult to pull out the pump. So, continue to maintain the status quo, continue to smoke! I didn't go to bed until half past one, praying that nothing would happen and everything would go well!

Good news. Lithium mineral water. Found it. At 11:10, good news came from the WeChat group of the project. The test results of mineral water in No.1 hole came out. The strontium content was 0.205 mg/l and the lithium content was 1.578 mg/L. The national standard of strontium in mineral water was 0.2-0.4mg/L. The water temperature was 25 degrees, and the lithium content was 0.2mg/L. The metasilicic acid content was 24.68 mg/L, and the national standard was 25 mg/l. The No.1 hole was finished and returned to the station at 4:30. The laboratory called to inform that the drinking water analysis results met the national standards and could be determined to be rare lithium mineral water. Today is the 23rd day of the 12th month of the lunar year, which is a small year in the north. (Note: I didn't know until the next day that it was the 24th day in the south.) The county magistrate Wang from the north invited the project team members to get together in the evening to celebrate the small year for us, and he felt very warm. At the same time, he thanked us for our breakthrough in finding water. At the climax of the dinner, we thanked the local government for its support. Now we added a dish to the small gathering, sent a gift for the Spring Festival, and told everyone the news of the discovery of lithium mineral water. There was jubilation during the dinner. Back at the hotel, he reported the good news about lithium mineral water to the head of the center, who said it was a major breakthrough and asked us to reconfirm the results. Get up at half past six and gather downstairs at seven. Gong said that he had just asked the staff on duty that the water level was basically stable and the water volume was still decreasing. On the way to the construction site, news came that the water volume had dropped to 34m ³/H, and bubbles began to appear. At the construction site, the personnel were divided into two teams. The first team measured the water level, which was still at 83m, while the flowmeter had read 0. The other team checked the water quality of the weir box. It looked a little muddy, but it was not serious. They fished out the sand at the bottom of the weir box with a shovel. There was no muddy sediment. Only a small amount of crushed granite particles were fished out. The well wall should not be damaged. At the same time, they discussed, or they used a drill to try to lift the pump to see if it was silted, and then they adjusted the pump capacity to be small, or they adjusted the pump capacity to be large to see the. First, increase the pump capacity, and the outlet pipe will soon have more bubbles, and finally the flow will be cut off; then, decrease the pump capacity, and gradually the full pipe will be ejected, the flowmeter will return to normal, and the water level will remain unchanged. It gradually stabilizes at 20m ³/H, and the water level gradually rises. Successful rescue! It may be that the flowmeter cannot work when the pipe is not full and there are bubbles; the water level gauge may fall down from the wall of the well at about 83m, causing the water level gauge to ring at this point; the bubbles in the outlet pipe increased and the flow was cut off just now, indicating that the actual water level has dropped to near or below the water inlet of the pump. When I went to the construction site at 2:30 in the afternoon, the water volume rose to 25m ³/H. After discussion, we decided to start the frequency conversion at 12:36 in the evening and draw the third drop. Piping of No.1 hole is completed. A change from cloudy to sunny Since entering Jiangxi, after ten days of sunshine and strong ultraviolet disinfection and blackening when the well location was determined in the early stage, from the hydrogeological drilling construction to yesterday, we have experienced the wet and cold rain outside in the southern winter for ten days, and the anxious mud after the carnival of double-well in the interior. Today, the sun finally came out again! Suddenly I feel the sunshine is brighter and warmer than before! Just in time to dry clothes in the shade, just in time to dry the wet mood of the past few days and yesterday. 2017.1.21 Gannan Poverty Alleviation and Water Search: Continue The gravel filling of No.1 hole is completed. Because of the continuous rain in the early stage, the car did not dare to get off the road, fearing that it would be trapped in the mud, so it could only rely on the old watch to carry gravel to the well location. The third drop pumping test of No.2 hole has been completed, and the water sample has been sent to the laboratory; the water level is being observed again; the pump will be lifted down the well pipe tomorrow. Tomorrow, the second group of members of the commando team will withdraw to the base camp with the vehicle, and the remaining members will continue to hold on until the No.2 hole is filled with gravel and sealed. The cars on the street are crowded, the pedestrians are thick, and the reason why all the migrant workers who have been away from home for a year come back. At dinner, what we saw in the restaurant we often went to was sparsely populated, almost our special show. Ask the waiter, only to know that the custom here is to celebrate the small New Year on the 24th day of the twelfth lunar month, and people have dinner at home. In the morning, the conciliator instructed them to fill gravel in No.1 hole at the construction site; at the same time, he prepared to lower the pipe in No.2 hole, and Li Si prepared to make a reducer with gas welding in hand, 273 to connect 219 well pipes. The floormen began to prepare the welded well pipe in pairs for the quick running of the pipe tomorrow, and the preparation work was very orderly and efficient. It is difficult to find clay here, so it is decided to seal the well section above 10 m of No.1 hole with cement and clay. In the afternoon, the leader of the center called to tell us that we had reported the matter of lithium mineral water to the leader of the Bureau, and the leader praised us. He also told us to make the results authoritative and verify them again. At the same time, it has also been reported to Deputy Director Wang Yan, who accompanied Vice Minister Ling in the investigation in southern Jiangxi. Director Wang will inform the leaders of the Ministry and the province at the forum tomorrow. It is planned to take mineral water samples and send them to more authoritative institutions for re-testing, and contact the person in charge of the laboratory. In order to do the work carefully, after discussion, it was decided to fill the No.2 hole with gravel to the top of the water outlet section, and after the festival, the clay ball made by our unit was used to stop the water. In this way, the work can be done carefully, and the work pressure before the year can be reduced. Photo 54-57 Hole 1 Cap and Gravel Fill Photo 58 Pumping test of No.2 hole 2017.1.22 Sunny, 3-14 degrees We had dinner at seven o'clock in the morning. Today, Gong, Fu, Chang Si and Li Si drove back to the base camp. We and they were all happy and excited. After the meal, I went to the construction site to do two things, one is to take water samples from the mountain spring under the Longhua Temple in Yangshan for analysis of drinking water and mineral water, and the other is to load and transport the test equipment from the construction site back. The well pipe of No.2 hole is basically welded in advance, that is, the original two 4m pipes are welded together, so that the speed will be doubled when the pipe is lowered. At 11 o'clock, the crane came. Fortunately, the crane boom was long enough to lift four pipes 12 m at a time when the pump was started. At 2 o'clock, the pump was finished and the speed exceeded expectations. After a little preparation, the pipe was lowered at 2:30. After the pipe was lowered, there was a difference between the reducing depth of 107m and 104m. After that, the total number of pipes was calculated and the well pipe above the orifice was measured and verified. The crane lifted the whole well pipe to a certain height, and then fell freely to see if there was a feeling of bouncing after the well pipe fell. Carry out gravel filling at 104-84 m, completed at 4:30; then go to hole 1, and carry out water stop for the upper ten meters, cement and sand 2:1, sodium clay powder and cement and sand 3:97. Mix the three into a batter and pour down. Finish at six twenty. When the solid pipe is welded, it should be welded according to the sequence number when leaving the factory, that is, the rotating seam on the coiled pipe should be connected up and down. When lowering the pipe, weld the steel plate across the weld vertically at the joint of two pipes, about 4 cm wide and 10 cm long. The vertical curved bridge centralizer shall be welded with steel bars above and below the filter pipe to avoid the deviation of the well pipe center and the uneven width of the annular gap around the pipe, which will affect the gravel delivery. At the wellhead, a steel bar with a length that can support the well pipe in the middle should also be used between the wall protection pipe and the well pipe, which is also convenient for gravel filling. In the process of gravel filling, in order to check whether there is dislocation between the well pipe base and the 104m variable diameter borehole, which may cause the leakage of interstitial gravel, a measuring rope with a heavy object is placed in the well to measure the depth before gravel filling and compare it with the depth after a certain thickness of gravel filling; At the same time, the measuring rope is used to measure the depth of the gravel filling layer in the annular gap to find out whether it is stuck and has a false height. In this process, a hammer is used to knock the wall of the well, and the stuck gravel is vibrated to fall smoothly to the bottom. With the knocking sound, there is a clattering sound of gravel falling. Listening to this sound, which indicates that the work is about to end, is like the most exciting music. The thickness is 20 m, the outer diameter of the well pipe is 219 mm, the outer diameter of the wall protection pipe is 325 mm, and the inner diameter is 310 mm. Calculate its volume, then calculate the volume of the bucket, and calculate the amount of 32 buckets, so as to have a good idea of gravel throwing. Cheng Jing Borehole XGZK01 was drilled to a depth of 155.00 m, with two 4.00 m-long φ219 mm sediment pipes at 155.00m-147.00 m and eight 4.50 m-long φ219 mm filter pipes at 147.00m-111.00 m. 111.00 m-Orifice is 28 solid pipes φ219 mm 4.00 m long. Borehole XGZK02 was drilled to a depth of 104.00 m, with one 0.70 m long φ219 mm to φ245 solid pipe (104.00 m-103.30 m) and five 4.50 m long φ219 mm filter pipes (103.30 m-80.80 m). 80.80m-Orifice is 20 pieces of 4.00 m long φ219 mm solid pipe and one piece of 0.80 m long solid pipe. 2017.1.23, December 26 For me, a special day, 29 years, thank you. 2017.1.24 Gannan Poverty Alleviation and Water Search: The First Stage, Perfect Finish According to Xing News Agency, the last group of members of the Gannan Poverty Alleviation and Water Search Commando Team of the Water Ring Center will bid farewell to Xingguo County, which has been struggling for a month, and will return to the base camp. Over the past month, the commando team has experienced the test of two days of ice and fire, fixed wells, drilled wells, pumped water, completed two demonstration wells for water supply, with astonishing water volume and gratifying water quality, far exceeding the expected target, and finished work perfectly. After 2020, the poverty alleviation work will continue to rely on the project in an orderly manner, looking forward to more heavy achievements and news, especially from the official release. Green is the precious wealth of rejuvenating the country, and green development is the fundamental guarantee for the sustainable development of rejuvenating the country. Goodbye, Xingguo! We also went home for the Spring Festival. I would like to thank my colleagues and friends for their continued concern, concern and support for the commando operation.
