Toilet pipe root blocking structure and construction process thereof

Abstract

The invention discloses a toilet pipe root blocking structure and a construction process thereof and belongs to the technical field of building construction. The toilet pipe root blocking structure is characterized by comprising a reserved hole formed in a cast-in-place slab (3) of a toilet, a pipe (1) penetrating through the reserved hole and a post-pored slab (8) arranged in the reserved hole, and a waterproof structural layer is arranged above the post-pored slab (8); the reserved hole is gradually shrunk inward from top to bottom, and the outer side face of the post-pored slab (8) tightly presses the inner wall of the reserved hole under the action of gravity. According to the toilet pipe root blocking structure, the reserved hole is gradually shrunk inward from top to bottom, the bonding area of the post-poured slab and the reserved hole is increased, in addition, the outer side face of the post-pored slab tightly presses the inner wall of the reserved hole under the action of gravity, and therefore the post-poured slab can be bonded to the reserved hole more firmly; quality of the pipe root is guaranteed, and the waterproof effect is improved; the toilet pipe root blocking structure is simple in construction process operation and high in qualified rate, and the construction period is shortened.

Description

technical field [0001] The utility model relates to a toilet pipe root sealing structure and construction technology, which belong to the technical field of building construction. Background technique [0002] Leakage from pipe roots in toilets is a common quality problem in engineering. During the construction process, leakage is prone to occur if the quality of toilet waterproofing is not in place. After handing over the house, if there is water seepage in the bathroom, it will be very difficult to maintain in the later stage, and the maintenance is difficult. For the various casings that penetrate the floor, the traditional method is to install the casings that pass through the floor together with the standpipes, and fix the casings before repairing the reserved holes, then install the hanging formwork and fill the reserved holes. The gap between the casing and the casing is sealed by pouring concrete, and finally the standpipe is passed through the casing (for rooms wit...

AI Technical Summary

Problems solved by technology

[0003] At present, in the pipe root sealing structure of the toilet, there are problems in the combination of the concrete in the reserved hole of the pouring pipe and the cast-in-place slab or floor slab, and the firm and tight combination of the concrete and the cast-in-place slab or floor slab cannot be guaranteed.

Secondly, the yin and yang corners at the junction of the pipe and the cast-in-place slab or floor (that is, the root of the pipe) are not handled well, and the concrete around the pipe is not dense, which leads to water leakage at the pipe root

Moreover, the waterproof layer at the existing pipe root is unevenly laid and the bond is not firm, which also causes the problem of water seepage or water leakage at the pipe root.
