A pre-embedded casing of civil air defense mouth and shear wall and its reinforcement method

Abstract

The invention relates to the technical field of civil air defense engineering, and discloses a civil air defense mouth and a shear wall pre-embedded casing, including a shear wall body, two fixed steel plates are arranged symmetrically inside the shear wall body, and the surfaces of the fixed steel plates are uniform There are a plurality of rectangular sockets, the rectangular sockets are inserted with rectangular steel sheath tubes, the opposite ends of the symmetrical two rectangular steel sheath tubes are uniformly connected with a first conical connecting cover, and the opposite ends of the two first conical connecting covers The same first circular steel sheath pipe is integrally connected, and the opposite ends of the two rectangular steel sheath pipes are integrally connected with a second conical connection cover. The pre-embedded casing of the civil air defense mouth and the shear wall and its reinforcement method can make the connection of the embedded casing of the shear wall more stable and durable, make the subsequent pipeline setting standard and convenient, and at the same time ensure the precise location of the pipeline. The relative position of the overall pipeline is reasonable, which improves the efficiency of on-site operations.

Description

technical field [0001] The invention relates to the technical field of civil air defense engineering, in particular to a pre-embedded casing of a civil air defense mouth and a shear wall and a reinforcement method thereof. Background technique [0002] The air defense mouth is the main body and the ground surface of the air defense basement, or the connection part with other underground buildings. For anti-aircraft basements with anti-virus requirements, the mouth refers to the part other than the innermost airtight door, such as diffusion chambers, airtight passages, anti-virus passages, decontamination rooms (simple decontamination rooms), dust removal rooms, poison filtering rooms and shafts, Passages other than protective airtight doors, etc. [0003] In modern architecture, reasonable and flexible space layout is emphasized, and pipeline settings require standardization, simplicity, and beauty; construction operations require improved efficiency and quality assurance. ...

AI Technical Summary

Problems solved by technology

The traditional setting of shear wall pipelines at civil air defense mouths adopts rear openings or reserved openings (rear openings or reserved openings are used for pipelines passing through later), and the reserved openings often have a large error in the overall elevation of the opening, and the rear openings It often causes inconvenient construction and high labor intensity. Both methods cause the overall structure to be uncoordinated, resulting in messy layout of the subsequent pipeline space; at the same time, the concrete strength and effective waterproofing of the reserved opening or the rear opening cannot be guaranteed.
