According to the emergency construction plan formulated by China Railway, a large amount of concrete will be poured into the artificial lake through two ZXLS-1911s of Zhengxin, and the funnel-shaped lake bottom formed by water injection and sediment invasion will be flattened.

Then, after the initial setting of concrete at the bottom of the lake. The simple steel plastic is built in the way of stepped operation, and a bottom shell is artificially made for the bottom of the lake with an area of 1,800 square meters!

This amount of work is actually not a big job for China Railway, which is used to doing big projects. It can be said that such a project is put in ordinary times, and the engineering team of any subordinate company of China Railway Twelfth Bureau is too lazy to do it.

But!

Today, this artificial lake injection and seepage prevention project has made the construction department of China Railway on the entire site like a great enemy.

Engineering is not a challenge in itself.

The temperature, which keeps dropping over time, is the worst enemy for everyone!

Lake construction site.

After detailed measurements and determination of the load-bearing structure of the lake, China Railway urgently allocated several small conveyor belts. In addition, six 2.5-meter-square openings were opened on the surface of the lake, and a large amount of quicklime began to be poured evenly into the lake from six directions of the artificial lake.

The main ingredient of quicklime is calcium oxide, which is absorbent and can be used as a desiccant. When used on this occasion, it can quickly absorb the water contained in the bottom of the lake.

What's even better is that this game reacts with water after encountering water to produce hydrated lime, which is mainly composed of calcium hydroxide and is relatively chemically stable.

At the same time, a lot of heat is generated!

Under the strong allocation capacity of China Railway, more than seven tons of quicklime have been poured into the bottom of the lake in just one and a half hours.

At this time, the temperature at the bottom of the lake has reached 15 degrees Celsius. Looking from the surface of the lake, three artificially dug holes are rising under the reflection of the engineering searchlight.

At the same time, the construction site of the tunnel under the lake.

The EPBM, which is worth more than 40 million yuan, has barely reached a working state after the technicians have drained the water.

After Shoshin ZXLS-1911 drained the lake and stopped the leak. The Yongdao that had been dug according to the "instructions" of the Russians finally played its role. With the coordinated efforts of the technical personnel of the 12th Bureau and the 3rd Company of China Railway, the damaged cutter head of the shield excavation machine has been replaced at the fastest speed, and the new cutter head has been replaced.

Wang Yuming, led by Zhao Fangshan, who was waiting to be dealt with, had already gone down to the tunnel and was giving a lecture to the engineers and technicians at the construction site.

"Now that the cutter head has been replaced, I ask you to get all the pebbles through by tonight. So that the construction unit behind him can do drainage and seepage prevention work!"

"But Wang, now the shield machine has just finished draining and has not yet dried. If, as you say, digging through the entire pebble layer tonight will cause irreversible damage to the EPBM. ”

"I don't care what method you use! In short, at 3 o'clock tomorrow morning, before the outside temperature reaches minus 26 degrees, I must dig through this pebble layer! During this period, the shield machine must not be shut down or replaced. As long as you survive tonight, this shield machine will be scrapped, and the group will replace it with a new one! But if you give me even one more fork tonight, you will automatically give me a fuck tomorrow morning!"

"Yes, we see!"

Above the man-made lake embankment, people who have been standing in the cold wind of the night for hours are still talking. Citizens, journalists, and foreign guests who are interested in water seepage in underground projects are all standing by the lake and watching the hot construction site with different faces.

Below the embankment in front of the crowd, Han Zhaojun, Wang Mingxuan, and the CEOs of a construction engineering company were also waiting for an impossible miracle.

By the artificial lake, two ZXLS-1911s, which look like monsters out of hell in the dark night, are also waiting.

In the nearby temporary commercial concrete station, a huge amount of concrete has been accumulated. As the mixing equipment inside kept making the noise of grinding teeth, several engineers from Zhengxin were also waiting. Wait for the desiccant at the bottom of the lake to finish reacting, so that we can start work early and go back to the hotel to sleep early.

Evening, eight twenty.

At this point, a full twelve hours had passed since the leak occurred at the bottom of the lake!

At night, the temperature has become very cold, and some of the citizens who watched the excitement have dispersed. The traffic flow on the road in front of the convention and exhibition center at night is not very large, and many traffic policemen who have been busy for an afternoon have also changed their guards.

But at this moment.

The China Railway Inspector, who entered the lake in a gondola with a desperate spirit, climbed up from the lake. used the walkie-talkie to excitedly convey an exciting news to the outside;

"The desiccant reaction has been completed, and the first waterproof layer has been constructed! At present, the temperature under the lake has reached 18 degrees Celsius! According to the current temperature drop rate, the temperature reached by the final setting of concrete can be completely maintained! Anti-seepage construction can be carried out! Repeat, the lake bottom environment can be constructed!"

"Okay!" Wang Yuming, who received the news, waved his fist fiercely, and then picked up the walkie-talkie, "Dong Li, let's start!"

Li Fanyu was about to fall asleep.

Woken up by the walkie-talkie, he lazily sat up from the seat in the ZXLS-1911's spacious control room and kicked Liu Qing, who had fallen asleep as a dead pig.

"Hey. Work. ”

……

Next.

At seven o'clock in the morning, the people who had left last night by the artificial lake, driven by curiosity, gathered again at the lake.

At this time, all the construction equipment has been removed from the lake. Only a long line of transport convoys was left by the lake, and the two ZXLS-1911s that had changed their parking spots.

Seeing this scene, people couldn't help but let out bursts of discussion;

"Did you make it? Why does it look the same as last night?"

"yes, it hasn't changed. I don't know if the bottom of the lake was blocked and seepage prevention was done last night. ”

"I look suspenseful. Think about it, how big is this artificial lake? The surface of the lake is 2,000 square meters, and no matter how small the lake is, it is still curvature. The area cannot be lower than the lake level. Can the construction of this dead cold day be done in one night?"

"yes, if it can be done. Hasn't that man become a god?"

"Head to head, let's disperse, let's come back in a few days. It is estimated that this is not a one-day or two-day project. ”

"I think it's the same, I'm gone, and the buns are cold for a while. ”

Several foreign merchants also shook their heads;

"The best time to deal with deep water is within 36 hours, but in winter temperatures, I'm afraid they can't repair it. ”

"Yes, in such a situation, we must stop work in our country and wait for the weather to get warmer. ”

"You can't say that, don't the Chinese say that their infrastructure technology is the best in the world? They will definitely think of a way. ”

"What's the solution? Let God cast a spell to warm up the temperature, or do you want to turn back the clock to the time when the subway line is planned to bypass this section of the death route?"

"Let's go, Miki, let's go back to the convention center. ”

But before everyone could turn their heads, there was a sound of machinery at work by the lake.

That's when people found out that the two big guys by the lake were ...... It doesn't look like it was yesterday!

Yesterday, when I was doing the card talk homework, the upper part was the kind of arm that resembled the tail of a scorpion. But now, I don't know when it has been replaced by that long, more than forty-meter long lifting boom!

At the end of the boom, there is a large, anchor-like barb-like device.

With the sound of hydraulic transmission, the boom of the two ZXLS-1911 slowly stretched out, reaching high above the lake.

Then, there was a "buzzing" sound of steel cables being released. The "anchors" raised by the two giant beasts smashed into the lake with lightning speed!
