On the evening of returning to the project department, Shu Cheng convened the members of the leadership team of the project department and the leaders of the two tunnel construction teams to hold a meeting in the small conference room of the project department.

The content of the meeting is very simple, that is, to discuss the problem of geothermal problems in the Devil's Cave tunnel.

Cooling tunnels is now crucial. At this time, sitting in the small conference room were Shu Cheng, secretary Zhan Yuntian, deputy managers Lin Xiaoyong, Wu Batian, Yan Yuyang, chief engineer Xu Jin, safety director Chang Kai, and Zhao Ritian and Qiao Ganglie's tunnel leaders Zhao Hong and Qiao Jun.

"This is not a real meeting, just let everyone discuss how to cool down the Devil's Cave tunnel, and everyone will express their opinions." Shu Cheng sat in the boss's chair and said to everyone.

Now it is only more than ten meters under construction, and the temperature is as high as more than 30 degrees, you know, the temperature outside the tunnel is only a dozen degrees during the day.

In the highland area, the amount of oxygen in the air is already low, and once the temperature is too high, it is easier for people to suffocate.

"Manager Lin, come first!" Shu Cheng looked at Lin Xiaoyong and said.

"My idea was to use ice, but it doesn't seem to be suitable now, because the ice in the river here in the project department has almost melted." Lin Xiaoyong said.

With May approaching and the weather getting hotter, the frozen rivers are now melting, and there is very little ice left, so it is obviously not practical to use this ice to cool the tunnels.

In addition, after a while, the temperature continued to rise, and the ice in the river melted by then, so what was used to cool down at that time?

"Manager Lin, this is not realistic, it's not winter now, where to find ice, if it's winter construction, you can also take ice directly from the river next to the project department." Wu Batiandao.

"Is it really possible to get ice cubes from the top of Kunlun Mountain to cool down?" Yan Yuyang said with a smile.

"You're trying to cause an avalanche!" Zhan Yuntian glared at Yan Yuyang and said.

Although Kunlun Mountain is not far from the Devil's Cave Tunnel, this ice cube has to go up to more than halfway up Kunlun Mountain, which is not so easy to do.

Obviously, Yan Yuyang's words are at least joking.

"It's really not good, use air conditioning! Build a large chiller outside the tunnel, and then bury air-conditioning sprinklers along the stone walls on both sides and top of the tunnel to cool down the tunnel! Wu Batian proposed.

"Don't freeze the migrant workers by then." Zhan Yuntian interjected.

In fact, the function of air conditioning is similar to that of air conditioning, but with the tunneling of the tunnel, how big does the machine to make air conditioning have to be satisfied?

This is not just a few hundred square meters of house, with an air conditioner can be done. In the case of a refrigerator, how much power is needed and other issues have to be considered.

"If you use water to cool the sides of the tunnel, I don't know if it will work." At this time, Xu Jin spoke.

"Tell me how to do it." Shucheng Road.

"Around the tunnel, we bury sprinklers facing the tunnel and spray water on the stone walls of the tunnel to lower the temperature around the tunnel, and this measure is also less expensive in all aspects." XU Jindao,

"Mr. Xu, the effect of this thing is not very ideal, during the construction, we also arranged people to splash water around, but in this way, special drainage ditches must be built on both sides of the tunnel to lead the water to the outside of the tunnel. In addition, the water freezes at night. Zhao Hong, the leader of Zhao Ritian's team, said at this time.

"Yes, during the previous construction, the construction team did use this method, but the effect was not great." Lin Xiaoyong also said.

In fact, the main problem is how to drain the water, constantly spraying water on the stone wall, which will inevitably lead to the difficulty of water discharge, and who will discharge it, a night, the water discharged to the outside of the tunnel, it is easy to freeze, the ditch at the mouth of the tunnel, the height will be higher and higher, it must be cleaned every day, otherwise, there is no way to continue to drain out.

"Qiao Jun, tell me what you think." Seeing that everyone was discussing for a while, and there was no good result, Shu Cheng said to Qiao Ganglie's construction leader.

Qiao Jun is a middle-aged man in his forties, who came out to do tunnels at the age of sixteen, and has rich experience in tunnels.

"Manager Shu, in fact, in my opinion, the most traditional cooling method is to use ice cubes to cool down." Qiao Jun said.

"But where are you going to get so much ice?" Wu Batian asked.

"In fact, whether it is refrigerant or water spraying, the cost of the project department is not small, especially the water is not easy to get and transported. Instead of that, it is better to make ice cubes and transport them in a car and place them on both sides of the tunnel. In addition, after the ice melts, a lot of water is slowly evaporated, unlike spraying water, which is sprayed all over the ground, so that there is much less water left on the ground. Qiao Jun explained.

Shu Cheng didn't expect Qiao Jun to say the truth as soon as he opened his mouth, but Shu Cheng had to admit that what Qiao Jun said had a certain amount of truth.

"The point is, how much does an ice-making machine cost?" Zhanyun Heavenly Dao.

"The large ice machine is the kind that makes ice bricks, and the price on the market is about one million now." Qiao Jun said: "It just so happens that I have a friend who is doing business in this area, and if the project department needs it, I can introduce it." ”

When Qiao Jun said this, he couldn't help but be stunned, he didn't expect Qiao Jun to be familiar with this aspect, no wonder just now, Qiao Jun recommended using ice cubes to cool down.

"Okay, why don't you give me your friend's number, and I'll get in touch with him." Shu Cheng pondered for a moment and spoke.

If there is a large ice machine that continuously supplies ice bricks to the Devil's Cave tunnel, the temperature in the tunnel will definitely be controlled.

And the ice brick cooling is not like water, he can be sustainable, an ice brick, as long as it is placed in the tunnel, if it has not melted, he is still absorbing the heat in the tunnel 24 hours a day.

In this way, the process of cooling down has been going on.

After all, the construction headquarters has ordered that starting from May 1, according to the requirements of the construction headquarters, the Tianli route will be carried out for up to six months, and strive to complete all the offline projects.

The task of the Shucheng project department is to complete the bridge substructure, subgrade filling construction and tunnel breakthrough work, and then withdraw from the site.

In other words, if nothing else, at the beginning of December, once the offline project in Shucheng is completed, as long as a small number of people are left here to do the finishing work next year, he can move on to other projects.

In the future, the construction of beams, laying ballast, lines and electrification projects will not be constructed by the Shucheng Project Department.

Because these works are all constructed by the beam project department, the paving project department and the electrification project department, the project department of Shucheng is only the construction project department in front of the station.

In the previous life, the day route was also constructed like this, and after the construction of the project department in front of the station was completed, it was directly withdrawn.

The next day, Shucheng arranged for the material department to contact the ice machine manufacturer, so that the other party could come to the project department, and there was also a price aspect, and further negotiations were required.

As for the on-site construction of the Devil's Cave Tunnel, it is still carried out slowly by using oxygen tanks to absorb oxygen, after all, the construction period cannot be delayed.

On the third day, Shu Cheng was in a meeting, and the little lord called Shu Cheng again.

"Manager Shu, the matter of the stone factory, I have encountered some trouble, why don't you come to Golmud in the evening?" The little lord said.

Hearing what the little lord said, Shu Cheng couldn't help but be stunned, the little lord was in Golmud, and he would actually hit a wall.

"What's going on?" Shu Cheng asked in a low voice.

"Someone else has their eyes on this piece of fat!" The little lord explained.

"I'm in a meeting, let's talk about it in Golmud in the evening!" Shucheng Road.

Although the meeting is held in the project department, it is better not to make a noise about this kind of thing.

In the afternoon, Shu Cheng drove to Golmud, ready to talk to the little lord about the stone factory.

The little lord is still waiting for the arrival of Shucheng in a four-star hotel in Golmud.

After parking, Shu Cheng walked straight into the hotel, and after explaining who he was looking for at the front desk, the waiter personally took Shu Cheng to find the little lord.

Before that, the little lord had already arranged people to receive Shucheng here.

Follow the waiter to the elevator to the fourth floor, and finally enter a luxury private room.

After pushing the door, I saw four people in the box, in addition to the little lord, there were two other young people, judging by their clothes, they should be rich children.

"Manager Shu is here!" Seeing Shu Cheng enter the door, the little lord hurriedly stood up.

At the same time, the other two young people just glanced at Shu Cheng, nodded slightly, and did not stand up, Shu Cheng knew that these two guys were probably not small.

"Little sir." Shu Cheng shouted.

"Manager Shu, let me introduce you, this is Ma Hao, the son of Deputy Director Ma of the Industrial and Commercial Bureau, and Liu Fa, the friend of Young Master Ma!" The little lord introduced: "Young Master Ma, this is the person in charge of the project department of the Devil's Cave Tunnel, Manager Shu Chengshu. ”

As soon as Shu Cheng listened to the introduction of the little lord, he felt that today's matter was not easy to handle.

The son of a deputy director of the Industrial and Commercial Bureau came to find the little lord, I'm afraid it's not so simple.

You must know that when a young lord builds a new stone factory, he must sign and seal the industrial and commercial bureau and the like, even if he is a little lord, he must have more than a deputy director to nod his head.

Obviously, the son of the deputy director of the Industrial and Commercial Bureau appeared here, obviously not wanting Shu Cheng and the little lord to swallow the fat of the stone factory and want to get a piece of the pie.

"Hello Young Master Ma!" Shu Cheng stretched out his hand.

At this time, Ma Hao stood up and shook Shu Cheng's hand gently, his eyes were very arrogant, and Shu Cheng didn't care.

Afterwards, Shu Cheng shook hands with Liu Fa and greeted each other.

"Sit down, everyone!" The little lord said. (To be continued.) )
