Chapter 380: Tunneling

The construction of the second heating hub went smoothly, but even if the construction is completed, this heating hub cannot be put into use immediately like the first heating hub.
The return well below is used to inject water into the ground, so this heating hub cannot directly extract heat from the underground, but can only rely on pipelines from the first heating hub at the railway station. Only the extracted hot water can play the role of a heating hub.
As for whether the hot water extracted from the first heating hub can be supplied to the second heating hub after its own evaporative heat dissipation and pipeline transportation, it depends on the first heating hub. The total amount of heat energy carried by the extracted groundwater.
"As long as the hot water extracted by the first heating hub can provide enough heat, there is absolutely no problem in supplying the two heating hubs." When faced with this question asked by Wang Hai, Chen Xin planned pipeline construction. He explained to him:
Moreover, each heating hub is equipped with an isotope temperature difference battery. The output power of the battery can maintain the heating hub operation as far as there is surplus, and the electric heating mode can be turned on when necessary. of."
After listening to Chen Xin's explanation, Wang Hai seemed to understand, he was just a soldier, and he didn't understand this kind of thing, so he was just a casual question.
Chen Xin naturally knew that Wang Hai didn't understand this kind of thing, but he just explained it smoothly, adjusting his mood after work.
Otherwise, working so boring all the time will make people very tired.
"In that case, the heating hubs to be built in the future will be in this two-two-group mode?" Wang Hai looked at the standard points on the map in front of Chen Xin, and after a little analysis, he judged that these points should be the future supply The place of the hot hub.

"Not necessarily, I may adopt a more effective method in the future." Chen Xin shook his head, opened the projection on the power armor, and projected the drawings of the heating hub and energy tower.
However, what Chen Xin projected this time was not a plan, but a three-dimensional image.
"This is the energy tower that I plan to build to mine deep geothermal energy. It will extract geothermal resources from a depth of more than 3,000 meters underground, transport a large amount of heat energy to the surface, and then transport it to various heating hubs through pipelines, and then pass The pipes under the heating hub were re-injected into the ground.
Chen Xin explained while controlling the projection to demonstrate, allowing Wang Hai to intuitively understand what kind of system it is and how it works:
This is me. The designed heating network, now the two heating hubs are just a test unit, to verify the feasibility of my assumptions, and the real heating network will not be built until the problems related to this technology have been verified. ."
Wang Hai looked at the projection demonstration in front of him, and couldn't help raising his eyebrows. Although he didn't understand well, he probably still knew the benefits that such a heating network could bring, which made him quite unconscious. feel.
But Chen Xin told Wang Hai these things, of course, not just to show him.
Limited by the troubles and troubles caused by pipeline construction, Chen Xin said this to Wang Hai, but he wanted to use his own thoughts while explaining these things to Wang Hai, so that he could use his brains and think carefully. I wonder if there is a way to complete the work of laying pipelines in a short period of time without using a lot of manpower.
Of course, part of the reason for this is also because Chen Xin himself is a person with a strong desire to express himself. He belongs to the performance personality and likes to show his ideas and ideas to others, which makes him feel very fulfilled.
This is like saying that a performer performing on stage will always need the audience to appreciate it. As a novelist, even if only an online novelist, Chen Xin hopes that more people can read and appreciate his works.
Even if he no longer writes books now, he hopes that the things he has created can be praised by others.
However, apart from the show off, Chen Xin is really thinking about how to solve the pipeline laying problem.
Now there is only such a short distance of several kilometers. It is a solution to the problem by investing a lot of manpower to dig, but it is indeed a dumb way.
If possible, Chen Xin hopes to have a more efficient and smarter way to solve the problem.
After all, if you want to build a heating network in a real sense, the laying of pipelines will inevitably become one of the difficulties in the construction process.
Rather than saving the trouble for later, it is better to think about how to solve this problem once and for all.
The optimal solution to this problem is of course the shield machine ~EbookFREE.me~ Although the use of shield machine has many problems such as high cost and unsuitable snow, but in the matter of tunneling, the shield machine does Is the best solution to the problem.
As for the problems of the shield machine, this is very easy to solve for Chen Xin, and it is good to use the system to carry out targeted upgrades.
As long as there is a system, Chen Xin has the confidence to transform a suitable shield machine.
Chen Xinzheng thought this way, but suddenly reacted. Since he can upgrade the existing shield machine, why not just design a shield machine that can be used here?
The real shield machine is used to build tunnels, not to mention its huge size, because it has to face complex topographical conditions such as rock formations and has extraordinary requirements for materials, and naturally the cost is very expensive.
But what Chen Xin needs to use here is different. First of all, what Chen Xin needs to face is not hard rock formations and complex soil layers, but just homogeneous and soft snow. In terms of material, even if Chen Xin uses wood A shield machine can also dig snow.
Moreover, Chen Xin doesn’t need to dig the hole as much as it needs to be able to lay the pipe in. Even considering the construction of the pipe laying, it’s just a diameter that can stand two people working in it. Up.
Even Chen Xin didn't need to dig the tunnel how strong it is, as long as it can be supported until the pipeline construction is completed, it does not matter to Chen Xin even if it collapses later.
And for digging such a tunnel, naturally the requirements for digging tools are not so high.
In short, Chen Xin does not need to build a real shield machine. All he needs is a tunnel boring tool, which is actually not difficult to build.
