Because we already have the experience of building the first heating hub, when building the second heating hub, both Chen Xin and Cao Daren have learned relevant experience and improved the construction process to make the construction of the second heating hub smoother.

For example, when building the first heating hub, Chen Xin and others first dug up the snow and laid the foundation underground before the heating hub was assembled. However, when building the second heating hub, they did not do so.

Instead, we use digging down while assembling the heating hub, digging the pit and assembling the equipment, and only need 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 were under intense construction, and Wang Hai led his combat team to spread warnings around him, while Chen Xin and Cao Daren were discussing the next construction plan.

The two heating hubs are now considered to be built, but one is a pumping well and the other is a return well. If they want to play their respective roles, they also need to lay pipes between the two towers and re-inject the water pumped from the pumping well into the ground through the return well.

However, laying this pipeline is a troublesome thing.

First of all, the bottom of the heating hub is at the original ground level, which means they are more than ten meters shorter than the snow-covered surface of the current snow.

The laying of pipes needs to be placed close to the ground, and cannot be placed on the snow. After all, when the heating hub works, it will melt the surrounding snow. The snow itself may be affected by natural factors such as wind and temperature, and it is not stable enough.

This means that the pipeline between the two heating hubs must be drilled under the snow that is more than ten meters thick before construction can be carried out.

As for digging up the snow, Chen Xin rejected the plan without even thinking about it. Not only would the construction volume be too large, it would be unpaid.

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 pipe, it is very simple without snow.

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

"Although it is feasible to let the workers dig holes, it is too low in efficiency and too slow. Although it doesn't seem to be far, it can't be dug in less than ten days or half a month! It's too time-consuming to do this." Cao Daren took the map and measured the distance between the train stations on it. He frowned and said to Chen Xin.

Chen Xin nodded. After such a long distance, it would take several days to build a pipeline before the disaster. Now it still needs to dig holes under the snow 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 how it is, this pipeline must be laid! Even if the workers are really digging with their hands in the end, they still have to dig it." Chen Xin first set the tone for this matter, and then said to Cao Daren: "Is there any other simple construction method? For example, melting snow, or using tools to save time?"

"Unless it is a shield machine, but where can I get a valuable thing like a shield machine in a small place like Lin City? Things that are not even in the city can only be obtained by going to the provincial capital. And even if you can get it now, I don't know if you can transport it." Cao Daren still knew about the shield machine, but he felt it was not realistic. This large-scale equipment specially used for underground holes is not that easy to think about.

"Is the shield machine? If you really want it, it is not impossible to get one..." Chen Xin knew that if he needed it, he could get it as long as he spoke, but this was not Chen Xin's first choice.

It’s not that Chen Xin is pretentious or something, but that he thinks that laying a pipe under the snow is not necessary to use large equipment like a shield machine.

They were not trying to build a subway, nor were they facing hard rock layers, but just snow. If it weren't for the snow that was more than ten meters thick, and he wanted to shorten the construction period and let the workers dig with their hands.

You should know that a shield machine costs tens of millions of yuan. You can dig in and lay pipes while laying them. It is really a waste of money to deal with snow.

Cao Daren didn't know what Chen Xin was thinking. When he heard him say that he couldn't build a shield machine, he was surprised: "Writer, don't you really want to build a shield machine, right? That's too wasteful. If you have the skill of building a shield machine, it's better to find a few more workers to work separately to increase efficiency!"

"This is also a method, but is there no better method?" Chen Xin could certainly think of improving efficiency in section construction, which is also a practical solution, but Chen Xin still thinks there should be a simpler method.

However, he is not a stubborn person. He did not come up with a suitable method but did not force it. So he said to Cao Daren: "Since you can't think of any good method now, you can only use sectional construction. I will contact the staff in Lin City to see if you can send some workers to us."

"Okay, as long as there are enough personnel, I can guarantee that the task will be completed on time according to quality and quantity!" Cao Daren agreed and made a guarantee on Chen Xin's chest.

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

But Cao Daren looked at the special forces guarding around him and couldn't help asking Chen Xin: "Writer, can these soldiers come and help? I think they all have exoskeletons, and they will definitely work more easily than ordinary workers. If they help, then our construction will be much faster!"

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

"In this way, you can only rely on ordinary workers. I really envy them for having exoskeletons. That thing is simply a magical tool for working!" Cao Daren's words were full of regrets, and he looked at the exoskeleton on the special forces next to him.

Seeing his appearance, Chen Xin couldn't help but smile and said to him: "If you are really envious, I will think of a solution. If you can't get a shield machine, there will be no problem with a few sets of exoskeletons."

When Cao Daren heard Chen Xin say this, his face also showed a surprise expression: "Then the relationship is good! If there is an exoskeleton, the worker's work efficiency can be at least doubled!"
