Abstract

The invention relates to a plugging structure and plugging method for a small-section deep hole in a civil air defense overhead wall, and belongs to the field of civil air defense engineering. A resistance plate and a non-resistance plate are arranged in reaming areas at the two ends of a preformed hole in a manner of being attached to a wall body, and the resistance plate and the non-resistance plate are connected in a pulling manner through a harness cord screw rod. After the whole plugging process is finished, steel plates on the two sides of the hole and bolts are reserved in the structure and cannot be taken out, the thread concave-convex characteristic of the surface of a harness cord bolt is effectively combined with a grouting material to generate larger friction force, the holding and wrapping effect is improved, and the structure strength and plugging and sealing reliability are guaranteed. The shaving and chiseling workload on the original structure concrete in the structure treatment stage is small, and the damage influence on the original concrete structure is small. Grouting plugging operation is simple and convenient, and plugging work of corresponding requirements can be completed at a time. After the plugging measures are completed, the surface treatment traces of the structure are not obvious, and later decoration work is facilitated.

Description

technical field [0001] The invention belongs to the field of civil air defense engineering, in particular to a sealing structure and a sealing method for small-section deep holes on a civil air defense wall. Background technique [0002] The air wall of the civil air defense project is a wall that directly bears the shock wave load of a nuclear explosion, and needs to be able to resist a strong instantaneous load. At the same time, the airtight performance needs to be considered. After the shock wave of the nuclear explosion is completed, the wall structure cannot be damaged or cracked. [0003] At present, the country's current "Design Specifications", "Construction Quality Acceptance Specifications", and "Technical Measures" related to civil air defense projects do not involve providing standard practices on how to repair such holes. [0004] When this kind of construction treatment is involved, it generally requires relevant engineering and technical personnel to design ...
