Construction method for preventing leakage of restroom tubular well

Abstract

The invention provides a construction method for preventing leakage of a restroom tubular well. The construction method comprises steps of 1, reserving a pipeline hole at the floor position of the restroom tubular well, and installing a vertical pipe and a horizontal pipe; 2, building a part of an infilled wall of the tubular well, and installing a drain pipe enabling the inside and the outside of the tubular well to be communicated on the infilled wall; 3, scabbling and clearing the contact surface of original concrete and new concrete around the hole, and plugging the pipeline hole by pouring micro-expansive fine aggregate concrete in two layers, wherein the strength of the micro-expansive fine aggregate concrete is one level higher than that of floor concrete; 4, performing leveling and flashing on the floor surface and the wall surface in the tubular well, then continuously building the rest of the infilled wall, and arranging a check hole. By means of the construction method for preventing leakage of the restroom tubular well, plugging can be effectively performed surrounding the vertical pipe of the tubular well, gaps at connection positions are avoided, accumulated water in the tubular well can be drained effectively, and leaked water is prevented from flowing to the lower layer.

Description

technical field

[0001] The invention relates to a building construction method, in particular to a water leakage prevention construction method for a toilet tube well. Background technique

[0002] In civil buildings, all kinds of drainage pipes (such as sewage pipes, rainwater pipes, etc.) are often concentrated in the building toilet pipe wells, and it is easy for water to flow down the pipes to the lower residents due to leakage at the joints of various standpipes or inspection ports. The leakage in the tube well is mostly caused by the poor compactness of the concrete that blocks the hole at the root of the drainage standpipe or the poor rigidity and waterproofness of the concrete itself, or the linear expansion coefficient of the different materials of the drainage pipe and the concrete floor is different. After the melting cycle, gaps appeared at the connection between the drainage pipe and the concrete floor, causing leakage. This quality problem directly affected the...
