管道非开挖修复施工技术研究进展

Study on the Progress of Trenchless Construction Technology for Pipeline Repair

HDPE管穿插修复技术可以在微开挖甚至不开挖的情况下对在线旧管道实现修复和更新,让旧管道重获新生,同时延长旧管道的使用寿命,其对周围交通、环境影响小,具有较低的社会成本。本文对其研究进展进行了分析,相关结论可以为施工单位提供施工依据。

HDPE pipe repair technology can not even under the condition of excavation pipeline repair and replacement of old line dug in ajar,let the old pipe rebirth, and prolong the service life of the pipeline is old, the surrounding traffic, environmental impact is small, with low social cost, this paper analyzes the re- search progress and the related conclusions can provide a basis for the construction of the construction unit.
