Abstract

The invention provides an air-raid shelter backfilling and plugging device and a construction method thereof. The air-raid shelter backfilling and plugging device comprises a shelter body, a first stud is arranged on the inner side of the lower end in the shelter body, a positioning assembly is arranged at the lower end in the shelter body, and a formwork is movably connected to the interior of the shelter body through the first stud and the positioning assembly. The strength of the segmented concrete can be improved by additionally installing the angle steel framework, so that the segmented concrete can resist side pressure generated in the pouring process of the hole body backfill concrete, and when the segmented concrete is poured, the positions of the first supporting column and the second supporting column are stabilized through the installation assembly, so that the first supporting column and the second supporting column can stabilize the position of the formwork; and after subsection concrete pouring is completed, the formwork and the like can be removed for lower end plugging construction, materials are recycled, the plugging cost is greatly saved, and the backfilling mode is suitable for reinforcing the plugging device under the conditions that the geology of the bottom of the hole body is poor, and sludge exists and the like and suitable for hole body backfilling work under different actual conditions.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an air-raid shelter backfill sealing device and a construction method thereof. Background technique [0002] Civil air defense projects, also called civil air defense projects, refer to underground protective buildings built separately to protect personnel and material shelter, civil air defense command, and medical rescue in wartime, and basements that can be used for air defense in wartime built in combination 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] In today's society, due to the need to build new buildings on the air-raid shelter, the air-raid shelter must be filled densely,...
