Chapter 407

"After our discussion after synthesizing the opinions of all parties, the final design is like this." In the living room of Chen Xin's refuge, the designer in charge of submitting the design scheme is introducing the whole design scheme to him: "the maximum diameter of the main part of the ecological dome is 512M, the arc of the dome itself is 1.1rad, which is a round 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 the ground and one floor underground.

The central part is a small ecological circle and a heating hub which provides heat for the whole building. The main part of the building is distributed in a ring around the atrium.

The above ground part is mainly used for the placement of various laboratories, while the underground part is used as a weapon testing ground and storage warehouse, and space may be reserved for underground experimental institutions in case of emergency. "

After listening to the structural introduction of the main part of the ecological dome by the designer, Chen Xin was quite satisfied with the design, but after thinking about it, he still asked, "where are the military camp and the planting greenhouse I mentioned earlier, and do you plan to use the heating hub to heat the ecological dome?"

"Yes, the heating hub and energy tower technology is a very efficient way of geothermal utilization, and can be directly converted into electric energy. Compared with another power plant for power supply and the construction of a boiler for heating, the construction of geothermal power plant can not only obtain efficient and clean energy, but also heat the ecological dome, which is much less than other schemes." Obviously, the designer considered a lot of schemes before finally choosing the current design scheme.

Chen Xin didn't say much about it. Although the technology came from him, he didn't feel proud or other emotions about it. He just nodded his head and said, "it's enough to use the heating hub to heat the ecological dome, but it seems that power supply is another calculation according to your opinion?"

"Yes, according to our design, we should build an energy tower near the ecological dome to extract underground heat, mainly for power generation, and the remaining energy will be transmitted to the heating hub in the ecological dome for heating, and the circulating medium will be 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, it's a good application. It can generate electricity and heat. It's very good." Chen Xin nodded and was sure of the design of the scheme, but he looked at the design drawing and continued to ask, "so you put the planting greenhouse and military camp outside the ecological dome? Although connected together, it is not placed in the main body of the ecological dome? "

"That's right, because according to our calculation, it's not impossible to put the planting greenhouse and military camp in the ecological dome, but it will make the internal space crowded out and appear very cramped, so it's better to adopt such a design that can be spread out." The designer elaborated his design concept and explained it on the drawings: "we design the direction of the barracks as the main entrance. If we want to enter the ecological dome area, we must pass through the area where the barracks are located. In this way, it can also play the role of security and inspection.

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

"You know better than me in this aspect. Just follow your design. As long as you can meet my needs, nothing else will be wrong." Chen Xin did not express different opinions and opinions on this. After nodding, he continued to ask, "what are you going to do in construction? Use heating hub to bake snow and then level 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 more than ten meters of snow in front of his home, Chen Xin first thought of this construction method.

"Yes, so we will complete the construction of the geothermal power plant and the heating hub first, and then the construction of the ecological dome and other buildings." In the face of Chen Xin's question from Party A, the designer answered his question in great detail, saying everything: "after the construction of the geothermal power plant and the heating hub, we will first lay the foundation for the ecological dome, and at the same time start the construction of the military camp.

After the foundation is laid, the supporting part of the main steel structure of the ecological dome will be constructed through the 3D printing robot provided by academician Chen. After the overall completion, the glass exterior wall and internal structure of the dome will be laid. "

"Are glass walls reliable? Now, although the frequency of meteorite fall has been reduced a lot, but still occasionally see scattered meteorite debris fall to the surface, right? How do you think about this? " No wonder Chen Xin has such doubts. After all, the disasters of Bluestar are all caused by meteorite impact.

More than a year ago, even though Yanguo was not the main disaster area hit by meteorites, we could often see firestars falling down from the sky.

In such a case, it is not necessary to say whether it can resist the sporadic meteorite impact, but at least it should be ensured that after the impact, the whole building's external walls will not be completely broken, and all the things that need to be rebuilt will not happen.

"What we use is a multi-layer composite structure of glass exterior wall, the main material is tempered glass, and the sandwich is made to prevent crushing. At the same time, the glass itself has a heat absorbing coating, and the light transmittance can be adjusted according to the light intensity, so as to ensure maximum access to natural light and light radiation, and to have the effect of keeping warm." Obviously, the designer has given full consideration to this. He specially found out the design of the glass exterior wall from the drawings and said to Chen Xin with pride: "considering the possible meteorite impact, we adopt the hexagon honeycomb splicing design for the glass exterior wall. If the impact occurs, although some of the glass may be broken, it will not let the glass break through The bottom is crushed.Moreover, we have also made adjustments to the internal structure of the building. Even if there are many factors such as internal explosion or meteorite impact, the impact on the glass exterior wall will not be very strong, and it will not lead to the fragmentation of all the glass exterior walls of the whole building. "

"If so, I have no other opinions. Let's start the construction according to your design." Chen Xin felt that he knew enough, so he clapped his hand and said, "as for the 3D printing robots needed for construction, I will deliver them to you before we start."
