Doomsday Bunker Upgrade

"After our discussion after synthesizing the opinions of all parties, the final design plan is like this." In the living room of Chen Xin's refuge, the designer responsible for submitting the design plan is introducing the whole design plan to him: "The main part of the ecological dome is the largest. The diameter of the dome is 512m, the curvature 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 41.2 meters.

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, and the main part of the building is distributed in a circular shape around the atrium.

The aboveground 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, and what are your plans? Using 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 it can be directly converted into electricity. Compared with building another power plant for power supply and building a boiler for heating, building a geothermal power plant can not only Obtaining high-efficiency and clean energy, it can also heat the ecological dome, and the investment is much smaller than other schemes." The designer obviously considered many schemes comprehensively, and finally chose 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 a heating hub is used to provide ecological The dome heating is enough, but it sounds like the power supply is something else?"

"Yes, according to our design, an energy tower should be built near the ecological dome to extract underground heat, which is mainly used for power generation, and the remaining energy will be sent to the heating hub in the ecological dome for heating, and through the supply The return well under the thermal hub re-injects the circulating medium into the ground." 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: " 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, although it is not impossible to put greenhouses and military camps in the ecological dome, it will make the interior space crowded out and appear very cramped, so it is better to adopt such a design that can be spread out. Some." 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. It 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 others." Chen Xin did not express any different opinions or views on this, and continued to ask after nodding his head. : "What are you going 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 complete the construction of the geothermal power plant and heating hub first, and then proceed with the construction of the ecological dome and other buildings." Facing the inquiries of Party A, Chen Xin, the designer answered his questions in great detail. , it can be said that we know everything and say everything: "After the construction of the geothermal power plant and the heating hub, we will 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 you, 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 it is said that the frequency of meteorites falling has been reduced a lot, you can still occasionally see sporadic meteorite debris falling to the surface, right? How do you think about this piece?" No wonder Chen Xin has this question , 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 of ​​the meteorite impact, it was often seen that bolides fell from the sky.

Under such circumstances, it is not to say whether it can resist such sporadic meteorite impacts, but at least it should be ensured that after the impact, the entire exterior wall of the building will not be completely broken, and all reconstruction will happen.

"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 Obtain natural light and light radiation, and have 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, and introduced to Chen Xin very proudly: "Considering the possible meteorite impact, we used a hexagonal honeycomb splicing design for the glass exterior wall. If an impact occurs, although part of the glass may be shattered, it will not completely shatter the glass.

Moreover, 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 exterior wall will not be very strong, and it will not cause all the glass exterior walls of the entire building to be damaged. broken. "

"If that's 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 decided: "As for the 3D printing robots needed for construction, I will Delivered to you before work started."
