Construction method for preventing seepage and water leakage of flat and tongue-and-groove type pipelines

Abstract

The invention provides a construction method for preventing seepage and water leakage of flat and tongue-and-groove type pipelines. The waterproof construction method of external joints of the pipelines includes the following steps that A1, gaps at the external joints of the pipelines are filled with waterproof mortar; A2, the two sides of the external joints of the pipelines are roughened after filling; A3, after roughening is carried out, the waterproof mortar is used for applying plastering belts along the circumference of the pipelines at the roughening parts on both sides of the externaljoints at the external joints of the pipelines; A4, a plastic film is used for covering the plastering belts and the plastering belts are maintained for 2-4 days; and A5, after the plastic film is removed, waterproof sealant caulking is plastered on the plastering belts in the step A4. According to the construction method, the problem of water seepage / leakage at the construction joints of the flattype and the tongue-and-groove type pipelines is well solved, the construction is convenient, the material is simple and easy to obtain, the waterproof effect is remarkable, the cost is low, and theconstruction method has good promotion and use value.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an anti-seepage and anti-leakage construction method for flat-mouth and tongue-and-groove pipes. Background technique [0002] Concrete pipes are often used in the construction of sewage and rainwater drainage projects in municipal engineering, and also in the construction of drainage projects in highway projects. In the construction of concrete pipe drainage projects, the connection parts of each pipe are prone to water seepage or leakage. , and the existing anti-seepage and anti-leakage water treatment is difficult to effectively solve this problem, and it is easy to cause greater difficulties for engineering construction. Commonly used concrete pipes are divided into flat type, tongue-and-groove type and flat type and tongue-and-groove type according to the pipe interface mode. Among them, the seepage and leakage prevention construction methods of the flat and to...
