污水管线修复方案探讨与实施

Discussion and Implementation of Sewage Pipeline Repair Plan

我国很多城市的排水系统存在不同程度的损坏现象。本文结合北京市大兴区新凤河流域综合治理工程的水环境治理工程一标段不同的污水管径及损坏情况,确定DN500以下混凝土管采用胀插管修复方案,DN1500采用内衬修复方案,其余情况采用插管修复方案。通过对各修复方案的探讨可知,上述修复方案具有技术可行、质量达标、施工效率高、施工安全有保障、修复费用较低的特点,可以为今后的类似工程提供参考。

The sewerage system of many cities in China has different degrees of damage.Combining the different sewage pipe diameters and damage conditions in the first section of the water environment treatment project of the Xinfeng River Basin Comprehensive Treatment Project in Daxing District of Beijing,this paper determines that concrete pipes below DN500 uses expansion cannula repair method,the DN1500 uses lining repair method,and the remaining cases use intubation method.Through discussion of each method,it can be seen that the above-mentioned restoration scheme has the characteristics of technical feasibility,quality up to standard,high construction efficiency,safe construction and low restoration cost,which can provide reference for similar projects in the future.
