Doomsday Bunker Upgrade

With several supporting columns as the warp and dozens of large and small rings as the weft, a cylinder composed of a grid quickly stood in the snow pit.

This is the main structure of the heating hub. All the rings are nested on the support column and connected to the support points by welding and bolts. The whole is quite stable, even if Chen Xin uses the power armor to push it twice. , And there is no shaking.

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

The brackets and horizontal plates were mounted on the wall of the main support frame and the snow pit, and the workers started the second stage of construction, installing the evaporative heat sink for the main support frame and installing related pipes.

The whole installation work has four stages, and the remaining two stages are the installation of the outer heat sink 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 childcare workers, these highly motivated workers have already advanced the construction period a lot. According to the current construction schedule, the entire construction period has been advanced by almost half a day, and the entire construction period has been shortened by 30%, which is an achievement. Quite gratifying.

Compared to the gratifying progress of the construction period, Chen Xin was worried about whether another matter would delay his time.

That is about the location of the return well.

Obviously, this return well cannot be found anywhere to be drilled. As for the reason, it has already been said that the construction of the return well cannot be carried out before the geologists arrive.

So Chen Xin is now very worried. It is very likely that the pumping well here has been completed, the heating hub is already operational, and the return well over there has not been located.

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

Fortunately, Chen Xin's worries did not become a reality. When the workers were installing several core components of the steam radiator on the main support frame, another train drove into the railway station in the city.

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

And it was not just a geologist who came here, but a geological exploration team composed of several geologists.

"You are Comrade Chen Xin? Hello! I'm from the Geological Bureau of Hunan Province. My surname is Zhang. You can call me Lao Zhang." A gray-haired old man held it with his powerful hands. Chen Xin greeted him warmly with the palm of his hand: "These are my colleagues. According to the instructions of the superior, we will cooperate with your work. Just tell me if you need it."

This old man who claims to be Lao Zhang is obviously very old, but his body is very healthy. Even in protective clothing, Chen Xin can feel the spirit and spirit of the old man in front of him, and his high spirits. Upward fighting spirit.

Chen Xin was a little surprised by the age of this old Zhang, but he thought that it would take time to learn, and geological work required a lot of time to collect geological data in the field, so he was not so surprised about the old man’s age. Up.

Under the recommendation, [\\mi\\mi\\reading\\app\\\\] is really good, it is worth installing, after all, there are many books, complete books, and fast updates!

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. In addition to two of them who should be college students, the remaining three team members are also They are all in their forties.

Through Lao Zhang’s introduction, Chen Xin learned that these three middle-aged people were all Lao Zhang’s former 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 became today's middle-aged uncle.

Looking at these geologists, Chen Xin deeply felt what it means to devote his life to his career.

Chen Xin did not make too much politeness with a few geologists. After greeted them and introduced himself, Chen Xin directly projected the design drawing of the heating hub with a mechanical arm of power armor. The person explained: "This device uses hydrothermal geothermal resources with a buried depth of about 400-800 meters to obtain heat. The main working principle is to pump up geothermal hot spring water whose temperature is much higher than the ambient temperature to dissipate heat through evaporation. The device radiates heat energy outward.

Although it is not impossible for the device to operate independently, the direct extraction of underground hot spring water in this way is undoubtedly a great waste of underground water and geothermal resources, and it will also affect the stability of the underground geological structure, so it needs to be in the same aquifer. A return well will re-inject the hot spring water that has been pumped up and passed through the heat into the ground.

Because of our lack of relevant geological knowledge and the lack of relevant data, we have no way to determine where this return well should be drilled, so we need your assistance from Professor Zhang to help us locate the water we have hit. The distribution and direction of the layers, and determine the location of the return well~www.ltnovel.com~ so that we can start the construction of the return well as soon as possible. "

"Your equipment is very convenient! The drawings are projected directly. If we had this equipment when we were engaged in geological work before, we don’t need to carry a lot of drawings that take up a lot of space. The current technology is really advanced. Ah!" Lao Zhang sighed, and Chong Chenxin nodded and said: "I already understand the situation. The higher-level department also told me about the situation before I came here. So I took the geothermal resource exploration that Hunan Province has done over the years. I have brought all the data. With these data, we only need to conduct an on-site survey to determine the distribution of the aquifer that Comrade Chen Xin needs and the appropriate construction site for the return well."

Lao Zhang should have developed the habit of vigorous and resolute in the past years of work. While talking to Chen Xin, he asked two young college students to open the luggage they had brought, and took out the relevant map from it. , Spread out in front of Chen Xin.

Lao Zhang pointed to the icon marked above and said to Chen Xin: "Comrade Chen Xin, look here. This is the mountainous area where the city is located. This mountainous area is a fractured zone. The geothermal resources here are actually very rich and very rich. Dense.

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

Lao Zhang's expression is full of positive fighting spirit. Even though his eyebrows are already white, he is far more motivated than the young college student who is responsible for moving things next to him.

After explaining the relevant situation to Chen Xin, he left two young college students responsible for arranging the luggage and building their residences, while he himself and his three students and Chen Xin hired a job in the city. The personnel set off with the required exploration equipment.
