Although Chinas construction industry has made some achievements, there are still some problems that seriously affect its sustainable development. In the construction of the project, water leakage will probably occur in the water supply and drainage pipeline after the project is completed, thus affecting the normal use of users. Therefore, it is necessary to conduct in-depth research on the anti-leakage technology of water supply and drainage pipelines, so that construction personnel can master the waterproof technology skillfully and reduce the possibility of water leakage. Based on this, the paper firstly analyzes the main reasons of leakage in water supply and drainage pipeline of construction projects, discusses the key points of construction technology of water supply and drainage pipeline, and discusses its quality control, so as to communicate with relevant parties.展开更多
