Chapter 380

Because of the construction experience of the first heating hub, when building the second heating hub, both Chen Xin and Cao Daren learned the relevant experience, improved the construction process, and made the construction of the second heating hub more smooth.

For example, when they built the first heating hub, Chen Xin dug up the snow and laid a good foundation underground before they began to assemble the heating hub. However, when they built the second heating hub, they did not do so.

Instead, we use the method of digging down and assembling the heating hub at the same time. After the pit is dug, the equipment is also assembled, and it only needs to be fixed to the foundation.

This construction method undoubtedly saves a lot of time. Although the installation period of a heating hub is not long, it is good to save some time.

The workers are working nervously. Wang Hai and his combat team spread out around to set up a guard. Chen Xinze and Cao Daren are discussing the next construction plan.

The two heating hubs have been built now, but under the two heating hubs, there is a pumping well and a return well. If they want to play their respective roles, they also need to lay pipelines between the two towers to re inject the water from the pumping well into the ground through the return well.

However, the laying of this pipeline is a troublesome thing.

First of all, the bottom of the heating hub is at the original ground level, that is to say, it is more than 10 meters lower than the current snow level.

The pipeline needs to be laid close to the ground, not on the snow. After all, when the heating hub works, it will melt the surrounding snow. The snow itself may be affected by wind, temperature and other natural factors, and it is not stable enough.

This means that the pipeline between the two heating hubs must be drilled under more than ten meters of snow before construction.

As for digging up the snow, Chen Xin vetoed the plan without even thinking about it. It's not worthwhile to say that the amount of construction is too large.

The distance between the seventh middle school and the railway station is not far, and the terrain is relatively flat. If you want to lay a pipeline, it is very simple without snow.

But once plus more than ten meters thick snow as the premise, simple construction will become very troublesome and difficult.

"It's feasible to let workers dig holes, but the efficiency is too low, and the speed is too slow. Although it doesn't seem far away, it can't be finished in ten days and a half months! It's a waste of time. " Cao Daren took the map and measured the distance between the seventh middle school and the railway station. He frowned and said to Chen Xin.

Chen Xin also nodded. For such a long distance, even before the disaster, it would take several days to lay a pipeline. Now it is still necessary to dig a hole under the snow more than 10 meters deep. Even if the snow is easier to dig than the soil, it is not an easy job, and the efficiency is low.

"But no matter what, the pipe must be paved! Even if we really let the workers dig by hand in the end, we still have to dig. " Chen Xin first set the tone for this matter, and then said to Cao Daren, "is there any other simple construction method? Like melting snow, or saving time with tools? "

"Unless it's the shield machine, but where can we get the expensive shield machine in a small place like Linshi? Things that don't exist in the urban area can only be obtained by the provincial capital, and now even if you can, you still don't know if you can deliver them. " Cao Daren knows about shield machine, but he doesn't think it's realistic. This kind of large-scale equipment specially used for underground drilling is not so ideal.

"Shield machine? If you really want one, it's not impossible... " Chen Xin knows that he can get it if he needs to, but this is not Chen Xin's first choice.

It's not that Chen Xin is hypocritical or anything, but that he thinks it's just to lay a pipe under the snow, and there's no need to use the shield machine.

They don't want to build a subway. What they are facing is not hard rock. It's just snow. If it's not that the snow is more than ten meters thick, and he also wants to shorten the construction period, so that workers can dig it by hand.

We should know that the cost of a shield machine is tens of millions, and it can lay pipes while driving, which is a real overkill to deal with snow.

Cao Daren didn't know what Chen Xin was thinking. He was surprised to hear that he could not get a shield machine: "writer, you don't really want to get a shield machine, do you? That's too wasteful. If you have the time to use shield machines, it's better to find more workers to work separately to increase efficiency! "

"It's also a way, but is there no better way?" Segmented construction can improve efficiency. Of course, Chen Xin can think of it, which is also a practical solution, but Chen Xin still thinks that there should be some simple methods.

However, he was not a sharp minded man. He didn't come up with a suitable method, but he didn't demand it. So he said to Cao Daren, "now that he can't think of any good method, he can only use the method of sectional construction. I'll go back and contact the staff in Lincheng to see if we can send some more workers to us. "

"OK, as long as there are enough people, I can guarantee to finish the task on time according to the quality and quantity!" Cao Daren agreed, and made a promise to Chen Xin.In fact, this kind of thing is simple and easy. As long as there are enough manpower to carry out the construction in sections, it is not difficult to save time.

But Cao Daren looked at the special forces on guard around him and asked Chen Xin, "writer, can these soldiers come and help? I think they all have exoskeletons, and they are certainly more efficient than ordinary workers. With their help, we can build much faster! "

"These are all special forces. They are different from ordinary soldiers. Besides, they are here to protect me. It's hard for me to ask them to help with the construction." Chen Xin shook his head and rejected Cao Daren's idea.

"In this way, we can only rely on ordinary workers. I really envy them for having exoskeletons. It's an artifact to work with." Cao Daren's words are full of regret. Looking at the exoskeleton of the special forces nearby, he is full of envy.

Seeing this, Chen Xin couldn't help laughing and said to him, "if you really envy me, I'll come back and find a way. I can't get the shield machine, and several sets of exoskeletons are still OK."

Cao Daren heard Chen Xin say so, his face also showed a surprise expression: "that feeling is good! If we can have exoskeletons, we can at least double the efficiency of workers! "
