Doomsday Bunker Upgrade Chapter 379: Pipeline construction

Because we already have the experience in the construction of the first heating hub, when the second heating hub was built, both Chen Xin and Cao Daren learned relevant experience and improved the construction process so that the second The construction of a heating hub became smoother.

For example, when building the first heating hub, Chen Xin and the others first dug out the snow and laid the foundation underground before starting the assembly of the heating hub, but they were building the second heating hub. When they did, they didn't.

Instead, the heating hub is assembled while digging downwards. After the pit is dug and the equipment is assembled, 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 always good to save some time.

The workers are working intensively. Wang Hai led his combat team to spread out around and set up guards. Chen Xin and Cao Daren were discussing the next construction plan.

The two heating hubs are now considered to be built, but under the two heating hubs, one is a pumping well and the other is a return well. If they want to perform their respective functions and operate, two towers are needed. Pipes are laid between them, and the water pumped from the pumping well is re-injected into the ground through the return well.

However, the laying of this pipeline is a hassle.

First of all, the bottom of the heating hub is at the original height of the ground, which means that they are more than ten meters shorter than the current snowy surface.

The laying of pipelines needs to be close to the ground, not on the snow. After all, the heating hub will melt the surrounding snow. The snow itself is also affected by natural factors such as wind and temperature. Possibly, it is not stable enough.

And this also means that the pipeline between the two heating hubs must be drilled under a dozen meters of snow for construction.

As for digging out the snow, Chen Xin rejected this plan without even thinking about it. It would not be worth mentioning that the amount of construction was too great.

The distance between No. 7 Middle School and the train station is not too far, and the terrain is relatively flat. If you want to lay a pipeline, it is very simple without snow.

But once more than ten meters of snow is added as a premise, simple construction will become very troublesome and difficult.

"Although it is feasible for workers to dig holes, it is too inefficient and too slow. Although it does not seem to be far away, the digging will not be completed after ten and a half months! This is too time-consuming. That's it." Cao Daren took the map, measured the distance between No. 7 Middle School and the train station on it, frowned and said to Chen Xin.

Chen Xin also nodded. For such a long distance, even if you want to lay a pipeline before the disaster, it will take several days to construct. Now you still need to dig a hole under the snow that is more than ten meters deep. Even if the snow is easier to dig than the soil, it is not an easy job, and the inefficiency can be imagined.

"But no matter what, this pipe must be laid! Even if workers were to dig with their hands in the end, they would have to be dug." Chen Xin first set the tone for this matter, and then he told Cao Daren. Says: "Are there any other simpler construction methods? Like melting snow, or using tools to save time?"

"Unless it’s a shield machine, but where can I get a shield machine in a small place like the city? You don’t have anything in the city, you can only get it in the provincial capital, and now even if you do it I don’t know if I can bring it here.” Cao Daren still knows about the shield machine, but he doesn’t think it is realistic. This kind of large-scale equipment specially used for underground drilling is not so good.

"A shield machine? If you really want it, it's not impossible to get one..." Chen Xin knew that if he needed it, he could get it as long as he opened his mouth, but it was not Chen Xin's. Preferred option.

It's not that Chen Xin is hypocritical, but he thinks it's just laying a pipe under the snow, and there is no need to use large equipment such as a shield machine.

They are not building a subway, nor are they facing any hard rock formations, but snow. If it were not for the snow to be more than ten meters thick, and he also wanted to shorten the construction period, let the workers dig it by hand. just dig.

Insert a sentence, [mimireadingapp\] is really good, it is worth installing, after all, there are many sources of books, all books, and fast updates!

You must know that a shield machine costs tens of millions, and it can be used to lay pipes while excavating, which is really overkill to deal with snow.

Cao Daren didn’t know what Chen Xin was thinking. When he heard that he couldn’t get a shield machine, he was a little surprised: "Writer, don’t you really want to get a shield machine? That’s too wasteful. Now, if you have the skills to get a shield machine, you might as well find a few more workers to split the construction to increase efficiency!"

"This is also a way, but is there no better way?" Chen Xin can certainly think of it~IndoMTL.com~This is also a practical solution, but Chen Xin still thinks There should be an easier way.

However, he is not a **** temper. He didn't think of a suitable method but didn't force it. So he said to Cao Daren: "Now that I can't think of a good method, I can only use the method of segmented construction. I Go back and contact the staff in Linshi to see if they can send us some more workers."

"Okay, as long as there are enough manpower, I can guarantee that the tasks will be completed on time according to the quality and quantity!" Cao Daren agreed and assured Chen Xin, patting his chest.

This kind of thing is actually simple and easy to say. As long as there are enough people to do the construction in sections, it is not difficult to save time.

It’s just that Cao Daren looked at the special forces guarding around, and couldn’t help but ask Chen Xin: “Writer, can these soldiers come to help? I think they all have exoskeletons, and they must be better than ordinary workers. Lisuo, with their help, our construction will be much faster!"

"These are all special forces. They are different from ordinary soldiers. Besides, people are here to protect me. I don't want to ask them to help with the construction!" Chen Xin shook his head and rejected Cao Daren's idea.

"In this way, I can only rely on ordinary workers. I really envy them for having exoskeletons. That thing is a magical tool for work!" There is no regret in Cao Daren's words, looking at the exoskeleton on the special soldiers next to him. envy.

When Chen Xin saw him like this, he couldn't help but smile, and smiled at him: "If you are really envious, I will look back and find a way. The shield machine can't be obtained, and a few sets of exoskeletons are fine. "

When Cao Daren heard Chen Xin say this, his face also showed a surprised expression: "That feeling is good! If there is an exoskeleton, the worker's work efficiency can at least double!"
