某管网工程新建污水管道修复更换对策研究

污水管道修复技术目前在大量改造的老旧排水管道上广泛使用。以某管网工程新建污水管道修复更换为例,提出非开挖紫外线原位固化修复、支护开挖管道更换+非开挖局部管道修复、现状钢筋混凝土管内衬钢管加固修复、管道周边注浆加固+管道内裂缝修复四个方案,并对该四个方案进行比选,最终推荐采用非开挖内衬钢管加固修复方案,可为类似工程提供参考借鉴。

Study on Countermeasures for Repair and Replacement of Sewage Pipelines in a Pipeline Network Project

The sewage pipe repair technology is widely used in the reconstruction of a large number of old drainage pipes now.Taking the repair and replacement of sewage pipelines in a pipeline network project as an example,four schemes of the trenchless ultraviolet ray in-situ curing repair,support excavation pipe replacement+trenchless local pipe repair,current reinforced concrete pipe lining steel pipe reinforcement repair and pipe perimeter grouting reinforcement+pipe internal crack repair are proposed.And these four schemes are compared and selected.Finally,the trenchless lining steel pipe reinforcement repair scheme is recommended.The relative experience can be referred for the similar projects.
