摘要
南京市雨污分流项目根据CCTV(闭路电视)检测发现,有3处排水管道部分损坏严重。损坏地点道路狭窄,不能长时间阻断交通,确定采用管道非开挖修复技术对管道进行修复。通过比选,决定采用"点状原位固化局部修复法"。详细介绍了具体施工步骤及3处管道修复作业情况和结果。
Nanjing Rainwater & Sewage Distribution Project is tested by CCTV and three parts of drainage pipelines are damaged seriously.The relevant road is narrow and the traffic cannot be obstructed for a long time,so pipeline trenchless repairing technology is determined to repair the pipeline.Through comparison and selection,spot in situ solidification partial repairing method is adopted.Moreover,the detailed construction procedures and working conditions and results of three parts of pipeline repairing are introduced in this paper.
