Drainage pipe pre-burying device with telescopic, waterproof and drainage functions and mounting method

Abstract

The invention discloses a drainage pipe pre-burying device with telescopic, waterproof and drainage functions and a mounting method. The drainage pipe pre-burying device comprises an outer device, an inner device and a concrete floor, the inner device is inserted in the outer device, a drainage vertical pipe is inserted in the upper end of the inner device, and the space between the drainage vertical pipe and the inner device is filled with a permeable flexible material. A drainage vertical pipe is inserted into the lower end of the inner device, the space between the drainage vertical pipe and the outer device is filled with flexible materials, a limiting ring is arranged on the outer wall of the top end of the outer device, the limiting ring is annular, a waterproof ring is arranged in the middle of the outer device, the outer device is directly embedded in the concrete floor, the inner device is installed in the outer device and has a certain horizontal direction adjusting space, position deviation caused by deviation of the outer device can be adjusted within a certain range, a toilet drainage vertical pipe is connected with the inner device, an upper floor drainage vertical pipe and a lower floor drainage vertical pipe can be installed separately, meanwhile, up-down free stretching and retracting can be achieved, and the drainage pipe pre-burying device can adapt to deformation adjustment within a certain range.

Description

technical field [0001] The invention relates to the technical field of embedded parts, in particular to a drainage pipe embedded device and installation method with telescopic and anti-drainage functions. Background technique [0002] In the construction of housing construction, the pipelines of toilets, kitchens, washing rooms and other places with drainage requirements must be installed through the floor. The gap is filled by pouring concrete for the second time by supporting the formwork. At the same time, a small pipe is drawn from the vertical pipe of the drainage as a channel for draining the accumulated water in the floor. In actual operation, the reserved gap around the pipe is not sealed tightly. Quality problems that cause leakage around pipelines often occur, and owners often complain to the corresponding administrative department of the government because the leakage of these parts affects normal use. Leakage is one of the common problems in housing construction ...

AI Technical Summary

Problems solved by technology

[0003] The present invention conducts research on the shortcomings and deficiencies in the installation method of the drainage pipe of the sunken toilet, and improves and innovates the original installation method of the drainage pipe. The purpose is to more effectively solve the quality problems caused by leakage in these parts , reduce or eliminate the influence of normal use due to leakage
