Doomsday Bunker Upgrade Chapter 406: Ready to start work

"After our discussion after synthesizing the opinions of all parties, the final design plan is like this." In Chen Xin's living room of the refuge, the designer in charge of submitting the design plan is introducing the whole design plan to him: "The ecological dome's The maximum diameter of the main part is 512m, the arc of the dome itself is 1.1rad, and it is a perfect circular structure. The diameter of the ground part is 496m, and the maximum height of the dome is 41.2m. The whole building is divided into three floors above ground and one underground floor.

The interior adopts a circular layout, with a central atrium consisting of a small ecological circle and a heating hub that provides heat for the entire building. The main part of the building is distributed in a circular shape around the atrium.

The above ground part is mainly used for the placement of various laboratories, and the underground part is used as a weapons testing ground and storage warehouse, and space for experimental institutions that may need to be placed underground is reserved for emergencies. "

After listening to the designer's introduction to the structure of the main part of the ecological dome, Chen Xin was quite satisfied with the design, but he thought about it and asked, "Where are the military camp and the planting greenhouse I mentioned earlier? Are you planning to use a heating hub to heat the eco-dome?"

"Yes, the heating hub and energy tower technology is a very efficient way of using geothermal heat, and can be directly converted into electricity, compared to building another power plant to supply electricity and building a boiler for heating, building geothermal power generation The factory can not only obtain high-efficiency and clean energy, but also provide heating for the ecological dome, which requires much less investment than other schemes." The designer obviously considered many schemes comprehensively before finally choosing the current design scheme.

Chen Xin didn't say much about this. Although the technology came from him, he didn't feel proud or had any other emotions about it. He just nodded and said affirmatively: "If you use a heating hub, It is enough to heat the ecological dome, but it seems that the electricity supply is another thing to hear?"

"Yes, according to our design, an energy tower should be built near the ecological dome to extract underground heat, mainly for power generation, and the remaining energy will be sent to the heating hub in the ecological dome for heating, And the circulating medium is re-injected into the ground through the return well under the heating hub." Since the designer will adopt this scheme, of course, he has a detailed understanding of the relevant technology.

"Well, this is a good application. It can generate electricity as well as heat. It's very good." Chen Xin nodded and was very sure of the design of this scheme, but he flipped through the design drawings and continued to ask Dao: "So you put the greenhouse and the military camp outside the ecological dome? Although they are connected together, they are not placed inside the main body of the ecological dome?"

"That's right, because according to our calculations, it's not impossible to put planting greenhouses and military camps in the ecological dome, but it will squeeze a lot of internal space, which is very cramped, so it is still possible to spread out in this way. The design is better." The designer explained his design concept, and also explained on the drawings: "We designed the direction of the military camp as the main entrance. If you want to enter the ecological dome area, you must pass through the area where the military camp is located. , which can also play a role in security and inspection.

The other two sides are the geothermal power plant and the planting greenhouse area, which are located on both sides of the ecological dome, so that the whole presents a triangular layout, so that each part can get enough space, and at the same time, the arrangement is relatively close. "

"You know better than me in this regard. Just follow your design. As long as it can meet my needs, there will be no problem with other things." Continue to ask: "What do you plan to do in construction? Use the heating hub to bake the snow before leveling the ground for construction?"

This is the method Chen Xin used in Linshi Railway Station before, and it is also his original intention to design the heating hub. Considering that there is also a dozen meters of snow in front of his house, Chen Xin first thought of this construction method .

"Yes, so we will first complete the construction of the geothermal power plant and heating hub, and then proceed with the construction of the ecological dome and other buildings." Facing the inquiries of Party A, Chen Xin, the designer answered in great detail His question can be said to know everything and say everything: "After the construction of the geothermal power plant and the heating hub, we will first lay the foundation for the ecological dome and start the construction of the military camp at the same time.

After the foundation is laid, the 3D printing robot provided by Academician Chen will carry out the construction of the main steel structure supporting part of the ecological dome, and the glass outer wall and internal structure of the dome will be laid after the overall completion. "

"Is the glass outer wall reliable? Although the frequency of meteorite falls has been reduced a lot, you still occasionally see sporadic meteorite debris falling to the surface, right? What do you think about this piece?" No wonder Chen Xin There is this doubt, after all, Blue Star's current disasters all come from meteorite impacts.

In the past year or so, even if the Yan Kingdom was not the main disaster-affected area by the meteorite impact, it was common to see bolides falling from the sky.

Under such circumstances ~IndoMTL.com~ does not say whether it can withstand such sporadic meteorite impacts, but at least it should be guaranteed that after the impact, the entire exterior wall of the building will not be completely broken, and the whole thing must be reconstructed.

“We use a multi-layer composite structure glass exterior wall, the main material is tempered glass, and the interlayer is made to prevent shattering. At the same time, the glass itself has a heat-absorbing coating, and the light transmittance can be adjusted according to the light intensity. To ensure maximum access to natural light and light radiation, and to achieve the effect of keeping warm." The designer obviously took this into full consideration, and deliberately pulled out the design of the glass exterior wall from the drawings, which Chen Xin is very proud of. The introduction: "Considering the possible meteorite impact, we used a hexagonal honeycomb splicing design for the glass outer wall. If the impact occurs, although a part of the glass may be shattered, it will not completely shatter the glass.

In addition, we have also made adjustments to the internal structure of the building. Even if there are many factors such as explosions or meteorite impacts, the impact on the glass outer wall will not be very strong, and it will not cause all the glass in the entire building. The outer walls are shattered. "

"If this is the case, then I have no other opinion. Let's start the construction according to your design plan." Chen Xin felt that he knew enough, so he made a final decision: "As for the 3D printing robots required for construction , I'll deliver it to you before work begins."
