[0002] At present, with the development of the national economy, prefabricated technology is a policy strongly advocated by the national government. A large number of prefabricated products are being built or under construction. At the same time, it will significantly simplify the installation operation, the assembly speed is fast, which is conducive to promoting the industrialization process, simpler construction, and industrial disassembly is very convenient and easy to install. In addition, at this stage, various flammable and explosive petrochemical products often cause huge casualties and economic losses due to explosions. In order to maximize the control of losses caused by fire and explosion, it is necessary to develop explosion-proof structures with good explosion-proof effects, especially in warehouses, shooting ranges, dormitories, ammunition depots, command posts, garages, Aircraft hangars, oil depots, equipment rooms, temporary warehouses, bomb disposal sites, field hospitals, checkpoints and other military fortification bases, as well as various inflammable and explosive petrochemical and other product processing plants, often cause huge casualties and economic losses due to explosions. In order to control the losses caused by fires and explosions to the maximum extent, it is necessary to build a series of projects such as military safety explosion-proof structures, three-dimensional fortification explosion-proof structures, training base explosion-proof structures, field material warehouse explosion-proof structures, field camp explosion-proof structures, dangerous goods warehouse explosion-proof structures, chemical plant explosion-proof structures, refinery explosion-proof structures, firecracker factory explosion-proof structures, storage warehouse explosion-proof structures, and barracks explosion-proof structures. In response to this series of problems, explosion-proof structures need to have high crack resistance, strong impact resistance, ability to withstand great impact pressure, good explosion resistance, extremely strong explosion resistance, high strength, great deformation ability, good buffering performance, can absorb the energy generated by the explosion impact to the maximum extent, can significantly control the disasters caused by the explosion, and can effectively play a fire and explosion prevention effect. At present, the problem of terrorism is becoming increasingly fierce internationally. All countries regard preventing terrorist bombings as an arduous task. my country's political form is relatively stable, but we cannot be careless either. In some special places, such as oil depots, airports, railway stations, etc., it is necessary to check the vehicles and personnel entering and leaving to prevent accidents, especially to prevent the huge harm caused by explosions, such as protecting against terrorist attacks in public areas. Therefore, it is necessary to develop an explosion-proof structure that can play a protective role in order to protect against and respond to terrorist attacks, especially in the case of terrorist explosions, it can effectively protect the personal safety of anti-terrorism personnel such as the military and police.
