城市排水管道非开挖修复技术在南方某地区的应用

Application of Trenchless Restoration Technology for Urban Drainage Pipelines in a Southern Area

城市排水管道承担着城市污水、雨水运输排放等任务,是城市平稳安全运行的基础。排水管道的老化情况具有不可见性,在地面上无法了解地下管道的状况,这会给管道业主带来经济损失,同时也会带来公众压力,因此管道非开挖修复技术的应用意义重大。结合南方某地区已建污水管修复工程的实例对非开挖修复技术进行研究,并探析其在市政管网修复中的应用。

Urban drainage pipes undertake the tasks such as the conveyance and discharge of urban sewage and rainwater,and are the basis for the smooth and safe operation of the city.The aging situations of drainage pipeline are invisible.It is hard to know the situations of underground pipelines on the ground,which will bring the economic loss to the pipeline owners,and also bring the public pressure.Therefore,the application of pipeline trenchless restoration technology is significant.Combined with an example of the built sewage pipeline restoration project in a southern area,the trenchless restoration technology is studied,and its application in the restoration of municipal pipeline network is further analyzed.
