Doomsday Bunker Upgrade

With several support columns as the warp and dozens of rings as the latitude, a cylinder composed of grids quickly stood in the snow pit.

This is the main structure of the heating hub. All the rings are nested on the support columns and connected to the support points by welding and bolts. The whole is quite stable, even if Chen Xin pushed it twice with the power armor , and no shaking was seen.

The stability of the main support frame also means that the subsequent construction has a good foundation.

After placing the brackets and horizontal plates on the main support frame and the pit wall of the snow pit, the workers started the second stage of construction, installing the evaporative cooling device for the main support frame and installing the related pipes.

There are four stages in the whole installation work, and the remaining two stages are the installation of the outer cooling plate and the overall assembly.

Compared with drilling and clearing snow, the entire installation work is relatively simple. According to the original construction plan, the workers can complete all the installation work within two days.

However, thanks to the high morale of the workers, these energetic workers have already advanced the construction period a lot. According to the current construction progress, the entire construction period has been moved forward by almost half a day, and the entire construction period has been shortened by 30%, which can be said to be an achievement. Quite gratifying.

It's just that compared to the gratifying progress of the construction period, Chen Xin is worried about whether another matter will delay time.

That's about the location of the backwater well.

Obviously, this backwater well cannot be drilled anywhere. As for the reason, it has already been said that the construction of the backwater well cannot be carried out until the geologist arrives.

So Chen Xin is very worried now. It is very likely that the pumping well here has been completed, the heating hub can be operated, and the location of the return well over there has not yet been selected.

In that case, unless Chen Xin decides to directly discharge the hot spring water that can be recycled from the pumping well, otherwise, the construction period will inevitably be delayed.

Fortunately, Chen Xin's worries did not come true. When the workers were installing several core components of the steam radiator on the main support frame, another train entered the railway station in Linshi.

In addition to the relevant disaster relief materials allocated by the state after learning about the situation in Linshi, this train also brought Chen Xin the materials he needed, as well as the most important geological experts.

And it is not just a geological expert, but a geological exploration team composed of several geological experts.

"Are you Comrade Chen Xin? Hello, hello! I'm from the Geological Bureau of Hunan Province. My surname is Zhang. You can call me Lao Zhang." Chen Xin's palm greeted him warmly: "These are my colleagues. According to the instructions of the superior, we will cooperate with your work. Just tell me if you need anything."

The old man who claimed to be Lao Zhang is obviously old, but his body is very healthy. Even if he is wearing protective clothing, Chen Xin can feel the spirit and energy emanating from the old man in front of him, as well as his high-spiritedness. Upward fighting spirit.

Chen Xin was a little surprised at the age of this old man, but he thought that it takes time to do scholarship, and that geological work requires a lot of time to collect geological data in the field, so he is not very surprised about the age of this old man. .

As for the other members of the geological exploration team who came with Lao Zhang, they are relatively young, but this is only relative to Lao Zhang. Except for two young people who should be college students, the remaining three team members are also All are in their forties.

Through Lao Zhang's introduction, Chen Xin learned that these three middle-aged people were all Lao Zhang's students. They have been engaged in geological work after graduating from university and have been working with Lao Zhang for more than 20 years. Two young teenagers like college students have become today's middle-aged uncles.

Looking at these geological experts, Chen Xin deeply felt what it means to dedicate his life to his career.

Chen Xin did not greet the few geological experts too much. After saying hello to them and introducing himself, Chen Xin directly projected the design of the heating hub with the mechanical arm of the power armor. The person explained: "This device is a device that uses hydrothermal geothermal resources buried at a depth of about 400-800 meters to obtain thermal energy. The main working principle is to pump up the geothermal hot spring water with a temperature much higher than the ambient temperature and dissipate heat through evaporation. The device radiates heat energy to the outside.

Although it is not impossible for the device to operate independently, the direct extraction of underground hot spring water is undoubtedly a great waste of underground water resources and geothermal resources, and it will also affect the stability of the underground geological structure. A backwater well will re-inject the hot spring water that has been pumped up and cooled down into the ground.

Because of our lack of relevant geological knowledge and lack of relevant data, we have no way to determine where the backwater well should be drilled, so we need your assistance from Professor Zhang to help us locate the water-bearing well we have hit now. The distribution and direction of the layers, and at the same time determine the location of the backwater well, so that we can start the construction of the backwater well as soon as possible. "

"Your equipment is very convenient! You can directly project the drawings. If we had this equipment when we were doing geological work in the past, we would not have to carry a lot of blueprints that were heavy and took up space. The technology is really advanced now. Ah!" Lao Zhang sighed with emotion, nodded to Chen Xin and said, "I already understand the situation, and the superior department also told me about the relevant situation before coming here, so I put the exploration of geothermal resources in Hunan Province over the years. All the data have been brought, through which we only need to conduct a field survey to determine the distribution of the aquifers you need, Comrade Chen Xin, and the appropriate construction site for the backwater well."

Lao Zhang should have developed the habit of acting resolutely during his work in the past few years. While talking to Chen Xin, he let two young college students open the luggage they brought and took out the relevant map from it. , spread out in front of Chen Xin.

Lao Zhang pointed to the picture marked on it and said to Chen Xin: "Comrade Chen Xin, look here, this is the mountainous area where Linshi is located, this mountainous area is a fissure zone, and the geothermal resources here are actually very rich and very rich. Dense.

The location where you are drilling the well should be a geothermal layer covering the entire urban area of ​​Linshi. The underground thermal energy reserves are quite rich. It would be great if it could be used effectively! "

Lao Zhang's expression was full of a positive fighting spirit, even though his eyebrows were already white, he was far more motivated than the young college student who was in charge of moving things next to him.

After explaining the relevant situation to Chen Xin, he left two young college students in charge of arranging the luggage and building their accommodation, while he himself, his three students and a city-based job recruited by Chen Xin The personnel set off with the required exploration equipment.
