Civil air defense door based on high barrier effect

Abstract

The invention discloses a civil air defense door based on a high barrier effect, and relates to the technical field of civil air defense doors. The civil air defense door comprises a door frame main body, the door frame main body is mainly composed of pre-buried layers, a lining frame and a sealing frame, wherein the lining frame is arranged on one side of the sealing frame and is integrally formed with the sealing frame, the pre-buried layers are arranged on the side surfaces of the lining frame, the pre-buried layers are connected with the installation position through concrete pouring, a filling sealing groove is formed in the middle position of the inner side of the sealing frame along the sealing frame, the edge position of the front side of the sealing frame protrudes forwards to form a sealing protrusion, sliding groove rods are arranged at the top and the bottom of one side of the sealing frame, and a sealing groove is formed in the edge of the outer side of the sealing protrusion. The impact force generated by explosion and damage of armor-piercing bullets can be effectively resisted, the sealing performance of the door body is higher, water seepage, toxic gas and toxic smoke flowing and the like can be effectively prevented, and the use convenience by people is greatly improved.

Description

technical field [0001] The invention relates to the technical field of civil defense doors, in particular to a civil defense door based on high barrier effect. Background technique [0002] Civil air defense projects are also called civil air defense fortifications, which refer to underground protective buildings built separately to protect personnel and material shelters, civil air defense command, and medical rescue in wartime, and basements that can be used for air defense in wartime when combined with ground buildings. Civil air defense projects are It is an important facility for guarding against sudden enemy attacks, effectively covering personnel and materials, and preserving war potential; it is an engineering guarantee for persisting in urban combat and long-term support for anti-aggression wars until victory; [0003] For excavated civil air defense projects, it refers to the civil air defense projects constructed by first excavating the earthwork of the foundation...

Problems solved by technology

[0003] For excavated civil air defense projects, it refers to the civil air defense projects constructed by first excavating the earthwork of the foundation pit to the design level, then pouring the project, and then backfilling with soil. That is, the tunnel, the civil air defense door of this digging type tunnel often has higher design requirements, and the existing civil air defense doors in this aspect often cannot meet the existing requirements, first of all, the part outside the door, the impact force of explosion and blasting needs to be improved , and more importantly, the airtightness of the civil air defense door cannot be improved, resulting in water seepage and gas flow. If the aggressor uses poisonous gas and flooding, it will not be able to effectively resist it
