    The construction of the second heating hub was very smooth, but even after the construction was completed, this heating hub could not be put into use immediately like the first heating hub.

    Due to the fact that the return well below is used to inject water into the ground, this heating hub cannot directly extract heat energy from the ground, but can only rely on the first heating hub transported by pipelines from the train 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 it has undergone its own evaporation, heat dissipation and pipeline transportation, it depends on whether the hot water extracted from the first heating hub can be used by the second heating hub.  The total amount of heat energy carried by the pumped groundwater.

    "As long as the hot water extracted by the first heating hub can provide enough heat, there is no problem in supplying it to the two heating hubs." When facing this question from Wang Hai, Chen Xin planned the pipeline construction  line, while explaining to him: "And each heating hub is equipped with an isotope thermoelectric battery. The output power of the battery is still sufficient to maintain the operation of the heating hub. When necessary, the electric heating mode can be turned on.  of."

    After listening to Chen Xin¡¯s explanation, Wang Hai seemed to understand. He was just a soldier. He didn¡¯t know much about this kind of thing, so he just asked casually.

    Chen Xin naturally knew that Wang Hai was half-understanding about this kind of thing, but he just explained it casually to adjust his mood after work.

    Otherwise, working so dull all the time will make people very tired.

    "In that case, the heat supply hubs to be built in the future will all be built in pairs?" Wang Hai looked at the standard points on the map in front of Chen Xin, and after a brief analysis, he judged that these points should be the heat supply hubs that will be built in the future.  Hot hub place.

    "Not necessarily, I may take a more effective approach in the future." Chen Xin shook his head, turned on the projection on the power armor, and projected the drawings of the heating hub and energy tower.

    But this time, what Chen Xin projected was not a plan view, but a three-dimensional image.

    "This is the energy tower I plan to build to mine deep geothermal energy. It will mine geothermal resources from a depth of more than three thousand meters underground, transport a large amount of thermal energy to the surface, and then transport it to various heating hubs through pipelines, and then through  The pipes under the heating hub are re-injected into the ground." Chen Xin explained while controlling the projection to demonstrate, allowing Wang Hai to intuitively understand what kind of system this is and how it works: "This is what I  The designed heating network, the two heating hubs are now just a test unit to verify whether my idea is feasible. The real heating network will not be constructed until all the related issues of this technology have been verified.  .¡±

    Wang Hai couldn't help but raise his eyebrows when he looked at the projection demonstration in front of him. Although he couldn't understand it clearly, he probably knew the benefits that such a heating network could bring, which made him feel quite uneasy.  Feel.

    But of course Chen Xin told Wang Hai these things, not just showed them to him.

    Limited by the troubles and troubles caused by pipeline construction, Chen Xin said this to Wang Hai just to explain these things to Wang Hai and smooth out his own thoughts so that he could use his brain to think carefully.  I wondered if there was a way to complete the job of laying pipes in a short time without using a lot of manpower.

    Of course, part of the reason for this is that Chen Xin himself is a person with a strong desire to express himself. As a performer, he likes to show his ideas and ideas to others, which gives him a great sense of accomplishment.

    This is like saying that when a performer performs on stage, he always needs an audience to appreciate him. As a novelist, even if he is just an online novelist, Chen Xin hopes that more people will read and appreciate his works.

    Even though he no longer writes books, he still hopes that what he creates can be praised by others.

    However, apart from the ostentatious display, Chen Xin was really thinking seriously about how to solve the pipe laying problem.

    Now that there is only such a short distance of a few kilometers, investing a lot of manpower to dig is a way to solve the problem, but it is indeed a stupid way.

    If possible, Chen Xin hopes to find more efficient and smarter ways to solve the problem.

    After all, if you want to truly build a heating network, the laying of pipelines will inevitably become one of the problems during the construction process.

    Rather than leaving the trouble to solve later, it¡¯s better to think about it now.How to solve this problem once and for all.

    The optimal solution to this problem is of course a shield machine. Although using a shield machine has many problems such as high cost and incompatibility in snow, the shield machine is indeed the best solution to the problem when it comes to tunneling.  plan.

    As for the problems with the shield machine, it is easy for Chen Xin to solve them. Just 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 Xin was thinking this, but suddenly he realized that since he could upgrade the existing shield machine, why not just design a shield machine that could be used here?

    The real shield machine is used to build tunnels. Not only is it huge in size, it has to face complex landforms such as rock formations and has extraordinary requirements for materials. Naturally, the cost is very expensive.

    But what Chen Xin wants to use here is different. First of all, what Chen Xin needs to face is not hard rock layers and complex soil layers, but just homogeneous and soft snow. In terms of material, even if Chen Xin uses wood,  Making a shield machine can also dig out snow.

    And Chen Xin doesn't need to dig the hole as big as it needs to be, he just needs to be able to lay the pipe in it. Even if he takes into account the construction problems of laying the pipe, it only needs to be a diameter that is big enough for two people to stand in it and work.  .

    Even Chen Xin doesn¡¯t need to know how strong the tunnel he dug is, as long as it can support it until the pipeline construction is completed, it doesn¡¯t matter to Chen Xin even if it collapses afterwards.

    And when digging such a tunnel, the requirements for excavation tools are naturally not that high.

    In short, Chen Xin does not need to build a real shield machine, all he needs is a tunnel boring tool, and this is actually not difficult to build.  (Remember the website address: www.hlnovel.com
