High-performance bionic blast wall

Abstract

The invention discloses a high-performance bionic blast wall member. The member consists of an FRP (Fiber Reinforce Plastic) protective layer and a high-performance wall body, wherein the FRP protective layer comprises a scaly FRP layer, a rubber layer and a polyurethane foaming plastic layer; the high-performance wall body is an ultrahigh-performance reinforced concrete wall or a prestressed block masonry shear wall; the scaly FRP layer is formed on the outermost layer of a blast wall; the rubber layer is adjacent to the FRP layer; the polyurethane foaming plastic layer is adjacent to the rubber layer; the high-performance wall body is adjacent to the polyurethane foaming plastic layer. The design concept of overcoming hardness with hardness in the conventional design is abandoned, and multiple defensive lines are adopted to couple hardness with softness. The scaly FRP outer layer is designed in reference to the lamination structure and mechanics principle of scales, and is an anti-impact layer of the member, the rubber layer is an energy consumption layer of the member, and the polyurethane foaming plastic layer is an energy attenuation layer of the member. The member has the characteristics of light weight, high strength and rapidness in building, blast impact waves can be resisted effectively, and the problems of wall breakage and even splash of scraps in an ordinary blast wall are solved.

Description

technical field [0001] The application relates to a high-performance bionic explosion-proof wall. Background technique [0002] The accuracy and power of conventional weapons in modern high-tech warfare have been greatly improved. The accuracy of precision-guided weapons is within 1 meter, and the accuracy of long-range precision-guided weapons is also within 10 meters, and it is still improving. The quality of conventional ammunition charges is improving. , The amount of charge is also increasing, especially the penetration technology for underground engineering has been greatly improved. The command system and key target protection projects are subject to more precise strikes, and the survivability of underground projects is seriously threatened. In addition, accidental accidents and terrorist activities also pose a threat to safety. Therefore, the risk prevention requirements for buildings are further improved. Existing solutions are usually to build blast-proof walls ...

AI Technical Summary

Problems solved by technology

Existing solutions are usually to build blast-proof walls such as brick walls or reinforced concrete walls. When these walls are subjected to strong shock waves, there is a risk of wall rupture and debris flying

Moreover, the attenuation ability of the single-layer explosion-proof wall to the explosion shock wave is very limited. The air overpressure caused by the shock wave passing through the wall will cause the destruction of other targets behind the explosion-proof wall and the injury of personnel.
