Problems solved by technology

[0004] 1) The space between the inner wall of the reserved hole and the pipe is filled with cement, and it needs to be tamped with a wooden mallet, which may cause the pipe to break, and there is a hidden danger of leakage. Pipes made of cement, plastic, steel, etc. cannot be completely sealed, and water seepage may occur Phenomenon, can not be completely waterproof
[0005] 2) After the water-swelling material swells with water for many times, the swelling effect will become worse, which will affect the waterproof and moisture-proof effect
[0006] 3) The currently used sealing, waterproof and moisture-proof measures are to fix and block the pipeline opening, which often causes damage to the pipeline during excavation operations, and is not conducive to pipeline expansion

Embodiment 1

[0056] Embodiment 1: The present invention is a prefabricated wall self-sealing waterproof cover with reserved holes, including a wall, a reserved hole is set on the wall, a pipe is arranged in the reserved hole, and a flexible pipe is arranged on the pipe. Liquid-filled self-sealing capsule, the liquid-filled self-sealing capsule is flat and covers the outer wall of the pipe. The liquid-filled self-sealing capsule is filled with antifreeze liquid and then expands to fill the gap between the inner wall of the reserved hole and the pipe, which can seal the reserved hole. The gap between the inner wall and the pipe is effectively sealed, which can achieve the purpose of waterproof and moisture-proof. The liquid-filled self-sealing capsule is provided with a long strip of Velcro, which can fix the liquid-filled self-sealing capsule. Protrusions are provided on the side of the liquid-filled self-sealing capsule close to the pipeline, and the protrusions are a plurality of strip-sh...

Embodiment 2

[0067]Embodiment 2: The present invention is a prefabricated wall self-sealing waterproof cover with reserved holes, including a wall, a reserved hole is arranged on the wall, a pipe is arranged in the reserved hole, and a flexible pipe is arranged on the pipe. Liquid-filled self-sealing capsule, the liquid-filled self-sealing capsule is flat and covers the outer wall of the pipe. The liquid-filled self-sealing capsule is filled with antifreeze liquid and then expands to fill the gap between the inner wall of the reserved hole and the pipe, which can seal the reserved hole. The gap between the inner wall and the pipe is effectively sealed, which can achieve the purpose of waterproof and moisture-proof. The material of the liquid-filled self-sealing capsule is rubber, which has the characteristics of good elasticity and acid and alkali resistance, which can make the use of the present invention not be affected by the acid and alkali environment, and has the characteristics of st...

Abstract

The invention discloses a prefabricated wall preformed hole self-sealing waterproof jacket and an implementation method and mainly relates to the technical field of architectural engineering installation. The prefabricated wall preformed hole self-sealing waterproof jacket comprises a wall. A preformed hole is formed in the wall, a pipeline is arranged in the preformed hole, and a flexible charging self-sealing bag is arranged on the pipeline. A strip hook-and-loop fastener is arranged on the charging self-sealing bag, protrusions are arranged on the surface, close to the pipeline, of the charging self-sealing bag, a thread seal nozzle is arranged at one end of the charging self-sealing bag, a liquid outlet is formed in the end, away from the seal nozzle, of the charging self-sealing bag, separable ferrules are arranged on the seal nozzle, and threaded holes matched with the seal nozzle are formed in the ferrules. The prefabricated wall preformed hole self-sealing waterproof jacket and the implementation method have the advantages that the interval between the inner wall of the preformed hole and the pipeline can be effectively sealed, so that the waterproof and damp-proof purposes are achieved, the sealing durability is improved, and later maintenance cost is reduced; construction cost is low, installation is convenient and quick, detachment is convenient, the pipeline cannot be damaged, enlargement is convenient, and high adaptability is achieved.

Description

technical field [0001] The present invention relates to the technical field of construction engineering installation, in particular to a self-sealing waterproof cover with a reserved hole in an assembled wall and an implementation method. Background technique [0002] With the rapid development of my country's economy and the gradual improvement of various urban infrastructures, prefabricated buildings and urban underground pipe corridors have become a trend in urban development. Prefabricated building wall reserved holes, power distribution rooms and basements generally reserve some casing holes on the wall for pipes to enter through the wall, but there is no seal, waterproof and moisture-proof treatment between the inner wall of the reserved hole and the pipe. can be effectively resolved. [0003] The currently used sealing, waterproof and moisture-proof measures mainly include cement plugging and setting water-swelling water-stopping materials around the pipeline. These ...
