Crossing the Western Tianshan Mountains

After dinner, Wu Yongjie and Ling Fengxi both entered the tunnel. The construction during this period was really too difficult.

December isn't actually midwinter at the foot of the mountain, but in the Western Tianshan Mountains, it's already deep winter. Extremely low temperatures cause frequent mechanical malfunctions, such as freezing lubricating oil and hydraulic system failures. This not only affects equipment operation but also makes it difficult to control force parameters.

When solving the problem of active fault zones, this impact will be maximized. Due to the instability of the force parameters, it is very likely that the active fault zone will suddenly collapse locally during drilling or grouting.

It not only has a great impact on the overall project, but also poses a threat to the lives of workers.

Moreover, such temperatures will also cause "frost heave" in the strata, resulting in worse stability of the tunnel surrounding rock and increasing the risk of collapse. Groundwater may also freeze, and the volume will eventually destroy the rock structure.

Two days ago, Li Jianguo and Yan Zhuoyu mentioned the issue of groundwater in their report. It turned out that since using the side-level pilot tunnel technology, they can actually detect the situation of the upcoming heading face in advance.

It is said that there may be "frozen" areas ahead.

At this time, Ling Fengxi and Wu Yongjie were no longer shocked by the "something location" suddenly reported by Li Jianguo and Yan Zhuoyu.

They have realized that this tunnel is really too long and will encounter problems and sections that have never been encountered in the tunnels built before.

As long as no one is killed, no matter what problem we encounter, we just need to solve it properly.

Of course, they also understood that this idea was too optimistic, because what they were doing could result in loss of life at any time.

The two of them tacitly stopped arguing and discussing, and instead personally monitored the construction. Ling Fengxi was more familiar with the machinery, so when he had nothing to do, he would watch over the workers who were responsible for maintenance, asking them to adjust the performance and status of the machinery to the best. At the same time, he paid special attention to the lighting and ventilation equipment in the cave. In any case, he had to ensure the normal operation of the basic facilities.

In order to control the strength of the project, Wu Yongjie personally worked on it for several hours almost every day. The reason was not other than that he wanted to be as familiar with the project as the workers and know what it was like.

What does each stone and layer of soil feel like under your hands? Because only by being as familiar with every inch of the project as the workers, and mastering the professional knowledge and control of the project, can you sense danger before the workers do.

So one day, when he was grouting with all his heart, he suddenly felt his hands stop moving, and there was a sense of looseness. His voice came out even faster than the thoughts in his mind, "Back off!"

He did not retreat himself, but only ordered the workers to stop the grouting machine. However, he still held the grouting machine carefully because it could not be moved at this time.

His feeling told him not to move!

Li Jianguo and Yan Zhuoyu were also nearby. When they heard the shouting, they immediately rushed over and lowered their voices, "Retreat, retreat, everyone retreat ten meters!"

Ling Fengxi also came. He said nothing, but stared at Wu Yongjie closely, then asked Li Jianguo in a low voice, "What's wrong?"

Li Jianguo said, "It might collapse."

Ling Fengxi's mind buzzed for a moment, but he immediately calmed down and said, "Think of a solution quickly."

At this time, Wu Yongjie was unable to speak at all. The two workers who were operating the grouting machine with him also stood there. They also felt the danger. One of them was so scared that he wet his pants. There was a faint smell of urine in the air, but no one laughed at him, because everyone saw that near the head of the grouting machine, slurry was slowly seeping out from the gap, and it looked like it was about to "explode".

Li Jianguo said, "Put up the support."

Yan Zhuoyu added, "Move slowly and put up the iron net at the same time."

But both of them knew that this was actually useless and had no effect on protecting the project. They just hoped that no one would die.

To ensure no tampering during the installation of the shoring, experienced worker Lin Jinghui led eight people, two each, toward Wu Yongjie and his team. The shoring was essentially a triangular steel frame that provided support. The key was that Wu Yongjie and two other workers were working together to support the grouting machine.

The stability of this grouting machine also has a certain effect on the stability of the surrounding rock at this moment.

Once Wu Yongjie and his team let go, the surrounding rock would inevitably crack and loosen, leading to "explosion".

Time passed by minute by minute, and no one dared to breathe. At the same time, they couldn't think of any good solution. Finally, Lin Jinghui said, "How about using a construction vehicle to block it?"

The only engineering vehicle nearby is a rock drill, which is mainly used to drill holes in the tunnel face for the installation of blasting equipment, and is also used for the preliminary drilling of holes for drilling and grouting.

The two drilling rigs they are using now are very expensive. Due to the special nature of the construction of the West Tianshan long tunnel, they paid a high price in the summer to get a fully computerized multi-arm drilling rig imported from Sweden. The other is the "Atlas" three-arm drilling rig that was once used in the Yunyang section of the Zhengzhou-Wanzhou High-speed Railway. Each one costs more than 10 million yuan.

Wu Yongjie objected immediately, his eyes reddening as he said, "No, these two cars are the lifeblood of this project. If they get blocked here today, who's going to compensate for the damage?"

Lin Jinghui's eyes were also red, "But human life is important."

No one knew the cost of these two cars better than Ling Fengxi, but he didn't hesitate at all. "If this is the only way, then do it. Save the people first."

He ordered, "People must be the priority, no one can be left behind!"

Ling Fengxi usually speaks very little, and everyone is afraid of him to speak except in meetings. But at this moment, his words were so powerful that many people at the scene suddenly had tears in their eyes.

Some workers began to discuss solutions in whispers.

The two workers who were holding up the face of the work with Wu Yongjie trembled and said, "Captain Wu, we are running out of time. We can't hold on any longer..."

Seeing the cracks on the palm surface getting bigger and bigger...

Wu Yongjie said, "Don't move, please, don't move, hold on a little longer, and don't speak."

The vibrations generated by their conversation now seemed to have an impact on the palm of their hand.

At this moment, Lin Jinghui suddenly exchanged glances with several workers and made gestures. Then Lin Jinghui signaled the other workers to continue to retreat carefully and leave some space. Ling Fengxi also retreated with the workers because he knew that having more people would be useless at this time.
