Doomsday Bunker Upgrade

Because we already have the construction experience of the first heating hub, when building the second heating hub, both Chen Xin and Cao Daren absorbed relevant experience, improved the construction process, and allowed the second heating hub to supply heat. Hub construction 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 when building the second heating hub, They didn't.

Instead, the heating hub is assembled while digging downwards. 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 were busy in construction. Wang Hai led his fighting team to spread out vigilance around, while Chen Xin and Cao Daren were discussing the next construction plan.

The two heating hubs are now completed, but one of the two heating hubs is a pumping well and the other is a return well. If they want to play their respective roles, they need to be laid between the two towers. Pipes, the water pumped up by the pumping well is re-injected 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, which means that they are more than ten meters lower than the current snow surface.

The laying of the pipeline needs to be 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 also be affected by natural factors such as wind and temperature. Not stable enough.

This also means that the pipeline between the two heating hubs must be drilled under a dozen meters of snow before construction can be carried out.

As for excavating the snow, Chen Xin rejected the plan without even thinking about it. It would not be worth it if the amount of construction would be too large.

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 when there is no 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, the efficiency is too low and the speed is too slow. Although it doesn't seem to be far, it can't be finished in ten days and a half months! This is too time-consuming." Cao Daren took the map and 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, it would take several days to build a pipeline even before the disaster. Now it is necessary to dig a hole under the snow that is more than ten meters deep. It is easier to dig than soil, but it is not an easy job, and the low efficiency can be imagined.

"But no matter what, this pipe must be laid! Even if the workers are really forced to dig by hand, they have to dig it." Chen Xin first set the tone for this matter, and then said to Cao Daren: " Are there other simpler construction methods? Like melting snow, or using tools to save time?"

"That's unless it's a shield machine, but in a small place like Linshi, where can you get such a precious thing as a shield machine? Things that are not available in the urban area can only be obtained in the provincial capital, and even if you can get it now, you can still get it. I don’t know if it can be transported.” Cao Daren still knew about the shield machine, but he thought it was unrealistic. 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 this was not Chen Xin's first choice.

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

They are not trying to build a subway, and they are not facing any hard rock formations, but just snow. If the snow is not more than ten meters thick, and he also wants to shorten the construction period, the workers will dig it by hand. .

You must know that a shield machine costs tens of millions. It can be used to lay pipelines while excavating. It is really overkill to deal with snow.

Cao Daren didn't know what Chen Xin was thinking. He was a little surprised when he heard that he couldn't get a shield machine: "Writer, don't you really want to get a shield machine? That would be too wasteful. It's better to find a few more workers to split up the construction to increase efficiency!"

"This is also a method, but is there no better method?" Of course, Chen Xin can think of improving the efficiency of segmented construction. This is also a practical solution, but Chen Xin still thinks that there should be a simpler way. .

However, he is not a sharp-headed man. He didn't come up with a suitable solution but he didn't force it, so he said to Cao Daren: "Since I can't think of a good solution now, I can only use the method of construction in stages. I will contact you later. The staff in Linshi, see if they can send us some more workers."

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

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

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

"These are all special forces, and they are 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.

"That's it, then we can only rely on ordinary workers. I really envy them for having exoskeletons. That thing works like an artifact!" Cao Daren's words were full of regret, looking at the exoskeletons on the special forces next to him, full of envy.

Seeing him like this, Chen Xin couldn't help but smile, and smiled at him: "If you are really envious, I'll look back and think of a way. If the shield machine can't get it, a few sets of exoskeletons are still fine."

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