摘要
以南方某市225.33 km排水管道为例,介绍了排水管道竣工验收CCTV检测的流程、标准,分析了检测结果,提出了建议。结果显示,排水管道合格率为75.79%,检查井合格率为93.36%;管道存在的缺陷主要为结构性缺陷,污水管道的合格率明显低于雨水管道。对结果产生原因进行了分析,提出了管理建议,为提升城市排水管道建设质量提供了参考。
Taking the drainage pipeline of 225.33 km in a city of southern China as an example,this paper introduced the flow and standard of CCTV detection for the completion acceptance of drainage pipeline,analyzed on the detection results,and put forward some suggestions.The results showed that the passing rate of drainage pipeline was 75.79%,and the passing rate of manhole was 93.36%;The main defects of the pipeline were structural defects,and the passing rate of sewage pipeline is significantly lower than that of storm sewer pipeline.The causes of the results were analyzed,and management suggestions were put forward,which provided an important reference for improving the quality of urban drainage pipeline construction.
