管道内衬高密度聚乙烯(HDPE)管非开挖修复施工技术

Study on trenchless repair technology of High Density Polyethylene( HDPE) pipe lining

鉴于非开挖技术的先进性,对其施工原理进行了研究,并在此基础上,从开挖操作坑、原管道改造、操作坑回填等方面,总结了非开挖式修复技术的施工方法,相关研究成果可为工程应用提供参考。

In view of the advanced trenchless technology,we studied the construction principle,and on this basis,from the excavation operation pit,the original pipeline reconstruction,operation pit backfill and so on,the construction methods of trenchless repair technology are summarized. Relevant research results can provide reference for engineering application.
