- Title:
- Application of Pipeline Potential Detection Technology in Tracing the Source of Urban Culvert Outlet
- 摘要:
- 南方某城区黑臭水体问题日益突出。控源截污是黑臭水体整治的前提和基础。为了实现控源截污，需对排口进行溯源。而该区路1和路2交叉口管线复杂，采用常规溯源方法如闭路电视监控系统、潜望镜检测等，易受管道和箱涵内水雾影响、耗时长、无法准确溯源到目标排口，而通过管道电位探测技术仅用3 d就溯源到了该路口3个目标排口(PW50、PW51和PW52)，同时找出了PW51和PW52上游相连的检查井W3和W1。该方法明显比常规溯源法迅速有效，可为类似项目提供参考和经验。
- Abstract:
- The problem of black and odorous water in a district of a southern city is becoming more and more serious. Source control and sewage interception are the premise and foundation of black and odorous water treatment. In order to control the source and cut off the pollution, it is necessary to trace the source. However, the complicated pipelines at the intersection of road 1 and road 2 in the district, make it difficult to use conventional tracing methods, such as CCTV and QV detection technology, which are easy to be affected by the water mist in the pipeline and box culvert, take a long time, and cannot trace the target outlet accurately. It only took 3 days to find out the three outlets including PW50, PW51 and PW52 at the intersection by pipeline potential detection technology, and the upstream checking well W3 and W1 of PW51 and PW52 were found out. Compared with the conventional tracing method, it is more efficient and can provide reference and guidance for other similar projects.
