Problems solved by technology

And after the plugging is completed, the curing strength is high, the moisture resistance is poor, and it is easy to harden and fall off. If you need to add pipelines, you need to drill holes on site, and the construction is not convenient enough
In addition, the current double-sided sealing technology not only has a complicated sealing structure and cumbersome construction

Abstract

The invention discloses a modular pipe hole sealing device for civil air defense projects and a use method thereof, and mainly relates to the technical field of civil air defense project pipelines andthrough-wall hole protective closing devices for the pipelines. The modular pipe hole sealing device structurally comprises a front pressing plate, a rubber pipe, sealing modules, a rear pressing plate, bolts and nuts. The front pressing plate and the rear pressing plate are respectively connected to two sides of the rubber pipe; the front pressing plate, the rubber pipe and the rear pressing plate are connected and fixed through multiple bolts; a rectangular fillet sealing space is formed inside the rubber pipe; multiple sealing modules are arranged inside the sealing space; and the sealingmodules comprise a plurality of solid unit rubber blocks having fan-shaped, square or rectangular-pore cross sections. The modular pipe hole sealing device disclosed by the invention has the beneficial effects that the sealing modules can be combined in various specifications, so that the modular pipe hole sealing device is wide in application range, convenient for construction, economical and environmentally friendly; a gap between the pipeline and the sealing space is effectively blocked to fulfill the aims of resisting striking of water, poisons, fire, nuclear weapons and conventional weapons; and the sealing effect is outstanding.

Description

technical field [0001] The invention relates to the technical field of civil air defense engineering construction, in particular to a modular pipe hole sealing device for civil air defense engineering and an application method thereof. Background technique [0002] In peacetime, use the sealing device to seal the pipeline passing through the civil defense wall. In wartime, it can not only resist the shock wave, but also ensure the normal operation of the pipeline and realize the wartime function. Usually, when laying pipelines inside the civil air defense project, it is necessary to pass through the protective airtight wall, and protective airtight measures are set at the perforated position, in order to meet the building's ability requirements for waterproof, anti-virus, anti-nuclear weapons, and conventional weapons. The traditional sealing method is to pre-embed a galvanized casing inside the wall, and weld a closed rib in the middle of the casing, and then weld it firmly...
