Anti-explosion closing part of wall bushing and plugging method of wall bushing

Abstract

The invention discloses an anti-explosion closing part of a wall bushing. The anti-explosion closing part comprises an elastic soft extrusion block, wherein clamping plates are arranged on two sides of the extrusion block, at least one pipeline hole and at least one connecting hole are evenly distributed at corresponding positions of the extrusion block and the two clamping plates, and fastening parts which are used for fastening, connecting and extruding the two clamping plates and the extrusion block are arranged inside connecting holes. The device has the advantages of being flexible and simple to construct, convenient to disassemble and change, capable of conducting construction after cables are fed through and the like. According to the device, matched closing parts can be used for plugging according to the inner diameter of the corresponding wall bushing and outer diameters of penetrating cables and pipelines after the arrangement of all pipelines and cables which penetrate through a wall is finished on site, so that the problem that construction sequences of different working shifts are disordered during pipeline construction is solved; besides, in the later usage process, when pipelines and cables are required to be added or reduced, only corresponding closing parts are required to be replaced, and then plugging can be finished, so that the replacement is convenient; and the closing part is attractive in appearance and free from construction pollution.

Description

technical field [0001] The invention relates to an explosion-proof sealing part of a wall-piercing casing and a sealing method for the wall-piercing casing. Background technique [0002] In the process of construction in various civil air defense areas, all kinds of wall-penetrating pipelines will be encountered. At present, civil defense projects, even major projects, cannot block the pipelines in a long-term, reasonable and effective manner according to the requirements of civil air defense. The most common treatment method in the process is to smear the pipe hole with a cement-like substance, and seal it after the substance hardens. However, this construction method is extremely unscientific and unreasonable, and cannot achieve the purpose of long-term air defense sealing. Because the cement will gradually deform under the action of gravity, the upper half of the pipe hole will not be sealed tightly, and even the cement will partially melt with the increase of temperature...

[0002] In the process of construction in various civil air defense areas, all kinds of wall-penetrating pipelines will be encountered. At present, civil defense projects, even major projects, cannot block the pipelines in a long-term, reasonable and effective manner according to the requirements of civil air defense. The most common treatment method in the process is: smear the pipe hole with a cement-like substance, and seal it after the substance hardens. However, this construction method is extremely unscientific and unreasonable, and cannot achieve the purpose of long-term air defense sealing

Because the cement will gradually deform under the action of gravity, the upper half of the pipe hole will not be sealed tightly, and even the cement will partially melt with the increase of temperature, which will lead to the failure of sealing

Moreover, the method of cement plugging is complicated in construction and ugly in appearance. It is very difficult to remove the cement construction in the future when adding or subtracting pipelines
