城镇排水管道CIPP紫外光固化修复技术工程应用

Engineering application of UV-CIPP for urban drainage pipeline

CIPP紫外光固化非开挖管道修复技术采用树脂体系和玻璃纤维织物组合的内衬管材料,耐腐蚀性强、强度高、抗冲刷能力强、自动化程度高、全程可视化控制、施工流程简单、效率高、施工风险低,是目前极具发展前景的非开挖修复技术。结合重庆市渝北城区环境综合治理PPP项目排水管道修复工程案例,详细介绍了CIPP紫外光固化技术原理、材料质量控制、施工工艺流程、原管道缺陷预处理、褶皱缺陷分析、施工质量控制及工程造价分析。

As the most promising trenchless repair technology,UV-CIPP uses a combination of resin and glass fiber fabric as the inner liner material,which has strong corrosion resistance,high strength,strong erosion resistance,high degree of automation,visual control throughout the process,simple construction process,high efficiency,and low construction risk.Combined with a case study of the PPP drainage pipeline repair project in Yubei District of Chongqing,the Technical principle,the material quality control,the construction process flow,the pretreatment of original pipeline defects,the wrinkle defect analysis,the construction quality control,and the project cost analysis of UV-CIPP repair technology are introduced.
