Plugging and leakage-proof construction method of kitchen and toilet flue and water supply and drainage pipeline edge

Abstract

The invention discloses a plugging and leakage-proof construction method of a kitchen and toilet flue and a water supply and drainage pipeline edge, belonging to a building construction method. The method comprises the following construction steps of: 1, preparing materials; 2, treating a reserved hole base layer, the flue and the pipeline; 3, proportioning and stirring plugging concrete; 4, pouring, plugging and cuing; and 5, managing at a later stage of construction, wherein the plugging concrete (C20) comprises cement, water, sand, stone and an expanding agent according to a mass ratio of 1:0.55:1.62:3.0:0.1; and the concrete plugging step comprises the following sub-steps of: (1) pouring a first layer of plugging concrete; (2) embedding a leak stopping master layer; and (3) pouring a second layer of plugging concrete. The method is easy and convenient to operate and quick in construction progress; and the problem of extremely high probability of leakage of the kitchen and toilet flue and the water supply and drainage pipeline edge is effectively solved.

Description

technical field [0001] The invention belongs to a building construction method, in particular to a construction method for a flue and a water supply and drainage pipe in a residential kitchen and bathroom. Background technique [0002] In housing construction projects, leakage between the kitchen and bathroom is a relatively common phenomenon, and it is also one of the main quality problems in construction projects. Once the waterproof construction quality of the kitchen and bathroom is not good enough, water leakage and seepage will occur, especially in the kitchen and bathroom. Leakage and water seepage around the flue, water supply and drainage pipes are the most difficult to deal with, and often cause discoloration, mold, and peeling of the kitchen and bathroom ceilings and indoor walls, affecting the use of functions, bringing inconvenience to the owners, and even causing property and economic losses. loss; during the construction process, according to the requirements ...

[0002] In housing construction projects, leakage between the kitchen and bathroom is a relatively common phenomenon, and it is also one of the main quality problems in construction projects. Once the waterproof construction quality of the kitchen and bathroom is not good enough, water leakage and seepage will occur, especially in the kitchen and bathroom. Leakage and water seepage around the flue, water supply and drainage pipes are the most difficult to deal with, and often cause discoloration, mold, and peeling of the kitchen and bathroom ceilings and indoor walls, affecting the use of functions, bringing inconvenience to the owners, and even causing property and economic losses. loss; during the construction process, according to the requirements of the acceptance specification: the kitchen and bathroom should be tested for water storage before and after the construction of the waterproof layer to achieve the effect of "double insurance". However, due to the quality awareness of the construction personnel and the construction method Improper installation can easily lead to insufficient sealing quality of the flue, water supply and drainage pipes, resulting in large-area leakage or annular leakage or sporadic point-like leakage at the side of the pipe, which will affect the construction quality
