紫外光固化非开挖修复在水环境综合整治中的应用

Application of UV Curing Trenchless Repair in Comprehensive Water Environment Improvement

城市的污水管道存在老化、塌陷、漏水、堵塞等问题,严重影响城市排水功能。但管网系统较为复杂,采用局部开挖修复成本巨大,而紫外光固化非开挖修复工艺能有效解决该问题。以金山新城区域排水管线维修改造及查漏补缺工程为例,对紫外光固化非开挖修复工艺流程、施工步骤、应注意事项等内容进行了探究。研究显示该技术具有对环境影响小、施工便利、可控性强等优点。

The urban sewage pipelines have problems such as aging,collapse,leakage,and blockage,which seriously affect the urban drainage function.However,the pipeline network system is relatively complex,and the cost of using local excavation for repair is huge.UV curing trenchless repair process can effectively solve this problem.Taking the maintenance and renovation of drainage pipelines in the Jinshan New City area as an example,this paper explores the process flow,construction steps,and precautions of UV curing non excavation repair.The research results show that this technology has advantages such as low environmental impact,convenient construction,and strong controllability.
