U型折叠内衬法在燃气管道修复更新中的应用

Application of U-shaped Folded Lining Method in Gas Pipeline Repair and Renewal

介绍了U型折叠内衬法施工流程,并对U型折叠内衬法、直埋PE管工艺和PE管穿插法等3种施工工艺在经济效益和社会效益方面进行分析比较。结合燃气管道修复改造工程实例,分析施工中产生的问题并给出了解决措施。最后对该施工技术的应用前景进行了探讨。

This paper introduces the construction process of U-shaped folded lining method,and compares it with the construction process of directly buried PE pipe and PE pipe insertion method in terms of economic and social benefits.Combined with the example of the gas pipeline repair and reconstruction project,the problems arising in the construction are analyzed and the solution measures are given.At the same time,the application prospect of the construction technology is also discussed.
