Description

Pre-buried facility that blocks water

Technical Field

The utility model relates to a pipeline is worn and is separated subassembly, especially a pre-buried facility that blocks water.

Background

Wall bushings are commonly used to pre-embed the pipeline within the wall. Generally, a wall bushing is installed in a wall hole of a wall body in advance, then cement concrete and the like are used for sealing, and the cement concrete is knocked off when a cable is laid subsequently. However, due to the expansion with heat and contraction with cold of the sleeve and the concrete, a gap may be formed between the sleeve and the wall, and the concrete is easily layered, thereby affecting the waterproof effect. Certainly, in the prior art, there is also a chinese patent with publication number CN210800267U that discloses a prefabricated modular water-blocking flange, which includes a flange and a sleeve, where one end of the sleeve is connected to the middle of the flange; a spiral groove is formed in one side, close to the flange, of the sleeve; a partition plate is also arranged in the sleeve, and the flange plate, the sleeve and the partition plate are integrally formed; the middle part of the sleeve is provided with a water seepage prevention baffle; the outer diameter of the water seepage prevention baffle is larger than that of the sleeve; the flange plate, the water seepage prevention baffle plate and the clapboard are integrally parallel to each other. Because the wall hole of wall body mainly accomplishes through manual operation drilling equipment, the accuracy of wall hole size is relatively poor, and prevention of seepage water baffle mainly through mechanized production, leads to there being the fit clearance between the two, and this clearance still can lead to the infiltration, and prevention of seepage water baffle is because the volume is great simultaneously, when getting into the wall hole of wall body, cuts with the wall hole inner wall of wall body easily and scratches the emergence damage, takes place the deformation even, further influences water-proof effects.
