摘要
为提升排水管网排查效率,重庆市结合实际情况采用一种以“目标、问题、结果”为导向,以“分区诊断、溯源排查”为路径,以“减量工作、找准源头”为效果的排查方法,即以主干管接入口或雨水排水口等关键节点为诊断着手点,基于节点水质情况,层层递进排查,判定缩小问题区域,再对问题区域进行排水管网检测,可有效缩短排查周期、节约排查成本、精确问题管段。
To improve the efficiency of drainage pipeline network inspection,combined with the actual situation in Chongqing,an inspection method taking"goals,problems and results"as the guiding,"zoning diagnosis and source tracing inspection"as the path,and"reducing the work and identifying the source"as the effect is adopted.That is,taking the key nodes such as the main pipe inlets or rainwater drainage outlets as the starting points for diagnosis,based on the water quality at the nodes,the inspection is conducted step by step to determine and narrow down the problem areas,and then a drainage network inspection is carried out in the problem areas,which can effectively shorten the inspection cycle,save the inspection costs,and accurately locate the problem pipe segments.
