PVC模块内衬法在排水管道非开挖修复中的应用

随着社会经济的快速发展,人们对城镇环境和防汛排水安全也日益重视,排水管网担负着收集和输送雨、污水的作用,是城镇防汛排水保障的重要基础。在排水管道运行使用的过程中,因排水管道结构性损坏造成的污染地下水、地面沉陷事故时有发生。非开挖修复技术可实现在交通繁忙的路段对排水管道的维修更新,结合实际案例,论述PVC模块内衬法在城市排水管道非开挖修复中的应用。

Application of BIM Forward Design in Expressway Interchange Engineering

With the rapid development of economy and society, people pay more attention to the urban environment, flood control and drainage safety. The drainage pipeline network plays the role of collecting and conveying the rainwater and sewage, which is an important foundation of urban flood control and drainage guarantee. In the operation of drainage pipeline, the accidents of groundwater pollution and ground subsidence caused by structural damage of drainage pipeline often occur. The trenchless repair technology can realize the maintenance and renewal of drainage pipeline in busy traffic section. Combined with the practical cases, the application of PVC segmental lining method in the trenchless repair of urban drainage pipeline is discussed.
