排水管道检测与非开挖修复技术的应用

城市地下管网系统错综复杂,燃气、上水、排水系统又相互独立。随着管网系统日益老化,加之地面道路环境复杂,无法对管网系统的运行现状进行有效检查,致使路面下陷、水管暴管、燃气泄露等恶性事故发生。介绍无须动土或尽量减少开挖面积的情况下,对管网系统进行管道电视检测、非开挖的CIPP翻转法、非开挖的U型折叠内衬等管道修复技术。

Techniques Applied to Detection and Trenchless Repair of Drainage Pipelines

The urban ground service systems are complicated, with the gas, water supply and drainage systems separate from each other. Increasing aging of the services and complicated conditions of ground roads made it difficult to perform effective inspection of the existing operation conditions thereof, causing severe accidents such as surfacing sinkage crack of water supply pipes and leakage of gas. Introduced hereby are pipeline repair techniques like television detection, trenchless CIPP turning and U-formed folding lining.
