Crossing the Western Tianshan Mountains

Wu Yongjie looks carefree, but he is actually very attentive. Fang Ya's subtle expression did not escape his eyes. He confidently gave her a wink, "Miss Fang, have you fallen deeply in love with me?"

Fang Ya suddenly became serious at this moment, looking at Wu Yongjie with a half-smile and said, "Love is something that can be controlled by reason. In the end, you have to choose who to love. But the heart is still difficult to control. My heart is not clear yet, and I am not in love with you, Captain Wu. I am very sorry."

Fang Ya packed up her medicine box and left. Wu Yongjie digested her words carefully, then gave her a thumbs-up from behind, "Lie! You're worthy of being the woman I like!"

Then he added, "I'll wait until you clear your mind. I have plenty of time!"

Yan Zhuoyu was studying the backfill materials at this time. In fact, there are many materials suitable for backfill, such as sand, gravel, etc. Even the debris that had previously poured in from the cavity is suitable for backfill. According to general methods, it should be based on the thickness of the material, such as thirty to fifty centimeters, and spread on top of the cavity.

Repeat this method to fill the cavity, and inject cement slurry or other chemical slurry into the cavity through the grouting pipe. The slurry will have a solidifying and reinforcing effect, fill all the gaps in the cavity, and have a good combination with the natural rock layer, thereby increasing the stability of the formation.

It seems quite simple, but the control of details will indeed affect the subsequent quality issues. Yan Zhuoyu called Li Jianguo and asked Li Jianguo for the test results of the slag layer of the 14th section.

Then, Wu Yongjie was given some very bad news. "Captain Wu, the debris and rubble that were dumped from the cavity cannot be used. We have to prepare our own sand and gravel for backfill."

"The investment is huge, so why can't the original one be used?"

"The soil that poured out of the cavity contains a special type of crystal that makes it soft and lubricated. Furthermore, this place is so close to the underground aquifer, so there are many smooth pebbles. The large rock that hit your back earlier is similar to this kind of pebble, making it very unstable. With these two factors combined, even if we use grouting, it will be difficult to ensure the stability of this soil layer."

Wu Yongjie stood up and ran into the cave to observe.

At this time, in order to backfill the cavity, a steel frame has been erected, and steel anchors have been used to support and reinforce the dome, greatly improving the safety of workers' operations.

The final work on the steel frame hadn't been completed yet; workers were welding. The smell inside the cave was extremely unpleasant and choking, and workers could be heard coughing from time to time. Wu Yongjie couldn't help coughing after only two minutes in. The sparks from the welding were also quite unpleasant, and for anyone without a welding mask, the mere sight of them could bring tears to their eyes.

Wu Yongjie covered his mouth and nose with a handkerchief and carefully observed the hole that needed to be backfilled. It was very large, as if a mountain had opened a huge mouth.

Wu Yongjie felt very uncomfortable after staying in the cave for a while and said to Lin Jinghui, "Let's stop here today. The environment in the cave is not good."

Lin Jinghui had actually felt it a long time ago, and he felt very uncomfortable too. At a command, everyone came out of the cave and stood outside the cave together, breathing deeply.

Wu Yongjie scolded Lin Jinghui, "You are experienced. Why didn't you lead everyone out earlier when you encountered this situation? If I hadn't gone in just now, who knows what terrible consequences would have occurred today."

Lin Jinghui coughed, clutching his chest. "Boss, what should we do? Logically speaking, the tunnel entrance has only just been opened, and it's less than twenty meters wide. It's not even close to the point where tunnel ventilation is needed. Should we stop and start the ventilation project?"

"Something's very wrong in the cave. Is it related to the void?" Wu Yongjie said. "Hold a meeting!"

"Yes!"

Everyone left the 14th site and returned to the camp to prepare for the meeting. Before the meeting, Wu Yongjie went to the medical room first. "Doctor Fang, there's something wrong with the environment in the cave today. Many workers are coughing. Do you have any medicine to remedy it? I don't want these young people to suffer from any health problems."

"In this case, we might need to urgently prepare a batch of salbutamol aerosols to prevent sudden respiratory spasms and casualties. Also, I have plenty of cough and expectorant medications like ambroxol. Workers can come to the medical room in batches and take the medication twice a day. The medical room will administer the medication per person for three days."

"Okay, I understand. Thank you, Dr. Fang."

Cheng Yue quickly stretched her head and asked, "Is Lin Jinghui okay?"

Wu Yongjie laughed at her, "Little girl, you're in love, and the only one in your heart is your Lin Tou'er. He's fine, but he has to come to the infirmary to take medicine. You can meet now."

Cheng Yue's face suddenly turned red.

Ling Fengxi naturally knew about this. He also entered the cave to feel it. Indeed, after staying there for less than a minute, he felt dizzy, short of breath, and coughing, as if he had been in a place smoked by fireworks.

Ling Fengxi didn't attend the meeting. He wrote a small diary in his tent, "The West Tianshan Tunnel can open up the north-south traffic in western China. I applied to take over this project, naturally with selfish motives. I promised Ayala that we would cross the West Tianshan Mountains, and I wanted to make sure that the West Tianshan Mountains would not become an obstacle to our love.

But now it seems that it is not easy at all. The construction of the West Tianshan Tunnel is a hurdle at every step, and it involves risking lives. Can we really succeed?"

At noon, Ye Minglang was not there. He was still worried about leaving his parents in the county, so he set out at noon to find his parents.

Later, they found Ye's parents in a shop selling Ailai silk skirts. Ye's mother was standing in front of the mirror, twisting back and forth in a uniquely patterned Ailai silk skirt. When she saw Ye Minglang coming over, she said happily, "Does your Kazakh girl often wear this? The people here aren't very good, but their clothes are quite unique."

Seeing them happy, Ye Minglang felt a little happier himself and said, "The people here are very nice too."

Ye's mother didn't intend to argue with him and continued, "I also bought a few sheets and pillowcases, and the hat they embroidered is so beautiful..."

She took out a hat from her bag and showed it to Ye Minglang. It was a "Chiman Dopa" worn by Uyghur women. It was a flower hat that was very gorgeously decorated and colorful.

This hat needs to be worn with a "veil" to cover the hair and part of the face.

Ye's mother had indeed bought a veil, which was now covering part of her face, looking at her husband and son with amusement. Her appearance also made Ye's father laugh, and he imitated the locals and praised: "Yaksimu!"

After leaving the clothing store, the family went out to eat.

This time, they chose a shop that specializes in milk tea and steamed buns, and also serves the local famous "braised pigeon." Father Ye ordered three servings, one for each of them, and two baskets of large steamed buns.
