Abstract

The sealing structure and sealing method of the small-section deep hole on the civil air defense wall of the present invention belong to the field of civil air defense engineering. The through-wire screw connects the resistance plate and the non-resistance plate by pulling knots. After the whole sealing process is over, the steel plates and bolts on both sides of the hole are retained inside the structure and cannot be taken out. The unevenness of the threads on the surface of the through-wire bolts can effectively combine with the grouting material to generate greater friction and improve the gripping effect. The structural strength and sealing reliability are favorable. The invention has less work load on the original concrete structure in the structure treatment stage, and has little influence on the damage to the original concrete structure. The grouting plugging is easy to operate and can complete the corresponding required plugging work at one time. After the plugging measures are completed, the traces of the surface treatment of the structure are not obvious, which is conducive to the later decoration work.

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 ...
