[0002] Civil defense doors are the doors at the entrances and exits of people's defense projects. Civil defense doors are used by the government to mobilize and organize the masses, take anti-air raid, disaster relief measures, implement rescue and reduce the harm of disasters, and protect the refugees. The classification of civil defense doors is relatively clear, including ordinary single-leaf and double-leaf protective closed doors and closed doors, single-leaf and double-leaf protective closed doors and closed doors with movable thresholds, and other civil defense equipment. Most of the civil defense doors currently seen are made of solid or honeycomb steel plates or concrete with simple structures. Due to its structural material, although it has a certain degree of protection, its protection effect is often limited when dealing with high-intensity impact or blast waves, and it is easy to lose its function due to deformation.
