排水管道检测与非开挖修复技术的应用

随着城市化的进展,城市地下管线扩建、改造工程量不断增加,城市地下管线错综复杂,给排水管道的修复带来了巨大的困难,由于非开挖施工具有对道路交通和周边环境影响小、施工效率高等优点,在国外已被广泛应用于城市地下管线改、扩建工程,在国内一些城市也开始使用。介绍了国内外几种主要的检测和非开挖修复技术,对提高城市排水管网管理与维护效率有着明显的作用,有助于增强城市排水管网运行的安全性。

Application of Drainage Pipeline Inspection Testing and Trenchless Rehabilitation Technology

With the urbanization progress, the extension and reconstruction of urban underground pipelines are continuously increased. The complicated and confused urban underground pipelines have brought the huge difficulties to the rehabilitation of water supply and drainage pipelines. The trenchless construction facilities have been widely used in the urban underground pipeline reconstruction and extension projects in the foreign countries because of its small influence on road traffic and surrounding environment, and its high construction efficiency, and also now started to use in some cities of China. The article introduces several main inspection testing and trenchless rehabilitation technologies at home and abroad, which have the obvious effects to improve the management and maintenance efficiencies of urban drainage pipeline networks, and is favorable to strengthen the operation security of urban drainage pipeline network.
