A kind of air defense basement structure

Abstract

The invention relates to a civil air defense basement structure, which includes an underground passage, a basement adjacent to the underground passage, an explosion-proof wall arranged between the underground passage and the basement, and an explosion-proof wall connected to the underground passage and the first door opening of the basement; a closing system for closing the first door opening is installed in the first door opening and the basement, and a camouflage system is installed on the first door opening on one side of the underground passage; the closing The system includes an explosion-proof door that can be opened or closed from the first door opening, and the camouflage system includes a billboard installed on the first door opening on one side of the underground passage. The present invention increases the concealment of the first doorway by arranging a billboard on the side of the first doorway located in the underground passage, and improves the time for the enemy to find the basement entrance, thereby gaining more time for the people to escape.

Description

technical field [0001] The invention relates to the technical field of basements, in particular to an air defense basement structure. Background technique [0002] Civil air defense projects are referred to as civil air defense projects, also known as civil air defense fortifications. They refer to underground protective buildings built separately to ensure the shelter of personnel and materials in wartime, civil air defense command, and medical rescue, as well as basements that can be used for air defense in wartime when combined with ground buildings. . The civil air defense project is an important facility to prevent sudden enemy attacks, effectively cover personnel and materials, and preserve war potential; it is an engineering guarantee to persist in urban combat and long-term support for anti-aggression wars until victory. [0003] At present, the patent document whose authorized notification number is CN107227794A discloses a kind of civil air defense basement. Temp...

AI Technical Summary

Problems solved by technology

[0003] At present, the patent document whose authorized notification number is CN107227794A discloses a kind of civil air defense basement. Temporary columns and steel plates are set up to form an explosion-proof wall. This technical solution solves the problems of low protection performance of the existing civil air defense basement and the greater impact of the superstructure on the civil air defense basement.

[0004] But above-mentioned a kind of air defense basement has following defect: because the door opening of air defense is usually exposed on the body of wall, the enemy is easy to find the position of door opening of air defense, thereby the explosion-proof wall at the door opening of air defense is broken down, so just reduces The escape time of the people
