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

Abstract

The invention discloses a civil air defense door based on high barrier effect, relates to the technical field of civil air defense doors, and comprises a door frame main body, the door frame main body is mainly composed of a pre-embedded layer, a lining frame and a sealing frame, wherein the lining frame is arranged on one side of the sealing frame The side and the sealing frame are integrally formed. The side of the lining frame is equipped with a pre-embedded layer, and the pre-embedded layer is connected to the installation position through concrete pouring. The middle position inside the sealing frame is provided with a filling sealing groove along the sealing frame. , the edge of the front side of the sealing frame protrudes forward and forms a sealing protrusion, the top and bottom of one side of the sealing frame are provided with chute rods, and the outer edge of the sealing protrusion is provided with a sealing groove, which can not only effectively resist The impact force generated by explosions and blasting and the damage of armor-piercing projectiles, while the door body has a strong seal, can effectively prevent water seepage and the flow of poisonous gas and smoke, and greatly improve the convenience of the people.

Description
