Description
Technical Field
The invention belongs to the technical field of construction of lunar residential bases, and particularly relates to a lunar surface type manned lunar building structure based on a future lunar base and a construction method.
Background
The exploration of the moon is a starting point of human beings for space environment cognition, adaptation, development and utilization, and is an important way for human beings to strive for wider development space. The moon building is an important foundation for the construction of moon bases, necessary facilities for exploring moon space environment and developing and utilizing moon resources in various countries, and also is an important content for the construction of subsequent moon bases in the fourth phase of Chang' e lunar exploration project in China. The moon building becomes a bottleneck which needs to be broken through urgently in future moon base construction, and the development of moon building research has great significance. China urgently needs to provide scientific, systematic and autonomous lunar building schemes, and basic guarantees are provided for building lunar bases, realizing long-term exploration of lunar environments and developing and utilizing lunar resources.
The moon building scheme can be classified into three types according to the construction mode: prefabricated, expanded, and constructed. The prefabricated building is a complete prefabricated building on the ground and then carried to the surface of the moon for installation, the prefabricated scheme is a rigid cabin made of metal materials generally, the maturity is high on the whole, the technical difficulty is low, but the provided working space and living space are limited, and the prefabricated building is only suitable for the construction of an initial moon base. The expansion type is characterized in that the building core part is prefabricated on the ground, the building core part is expanded on the moon surface, a larger using area can be obtained, the carrying constraint is smaller in size, compared with the prefabricated type, the expansion type is lighter in weight under the same cabin volume, better in expansibility and more flexible in application, the advantages of earth-moon construction can be effectively combined, and the scheme is stronger in feasibility at the present stage. In the construction mode, the building main body is constructed by utilizing the in-situ materials in the moon, the material preparation and construction and installation are required to be completed in the moon, the technical difficulty of the scheme is high, and the key core technology needs to be further broken through.
In the construction of lunar bases, the united states, europe, russia and the sun are in the leading position, various forms of lunar building ideas are proposed, and great progress is made through means such as ground simulation. China has not proposed a systematic design scheme in the field. The existing moon base building form in China is mostly a prefabricated rigid cabin, and the size of the rigid cabin is limited due to the limitation of a carrier rocket fairing, so that the corresponding internal use area is also limited. If the cabin section needs to be expanded, material transportation between land and months needs to be carried out for many times, so that the construction cost is increased, and the use requirement can not be well met along with the gradual development of the technology. Meanwhile, buildings constructed on the moon are different from the earth, the extreme moon environment needs to be considered, and the moon has the characteristics of high vacuum, strong radiation and the like. The gravity of the moon surface is about 1/6 of the earth, no atmosphere exists, the day and night period is as long as 27 days, the temperature difference between day and night is as high as 300 ℃, the moon surface is easy to be directly impacted by space meteorites and continuously bombarded by corpuscles, and the environment is extremely harsh.
Therefore, under the extremely severe lunar environment and the existing lunar relationship conditions, aiming at the existing lunar base, a novel lunar surface manned lunar building structure based on the future lunar base is needed to be designed, wherein the lunar in-situ resource can be fully utilized and the lunar combination in the underground mature building technology is accurately combined.

The earth-moon combination mode can fully combine the dual advantages of earth construction and moon in-situ resources, and comprehensively realizes the effective combination of earth-moon construction by following the construction principle from ground prefabrication to moon construction, from monomer to whole, from low skill to high skill, from passive to active, through prefabrication of a core cabin in the earth, unfolding of a cabin body in the moon and unfolding of a peripheral protective layer in the moon.
