摘　　要：随着城市建设的不断发展,城市人口不断增加,污水收集系统承受的压力越来越大,污水管网错接漏接以及管道本身破损、淤积现象日趋严重。由于空间和经济的问题,无法重新修建污水管道,对现状存在问题的污水管道进行排查整改势在必行。根据南京市某片区总长286.4km污水管道的全系统排查结果,对现状污水管网存在的问题从不同管材、管径及不同的损坏形式进行系统分析,以期为今后调查和分析现状污水管道系统提供依据,同时对新建污水管道提出设计和施工建议。With the construction and development of cities, the urban population and the pressure on the sewage collection system is increasing. Phenomena such as wrong connection, missing connection, damage and deposition of the sewage pipe network are getting more and more serious. Rebuild the sewage pipeline is hard to accomplish due to the shortage of space and economy, thus it is imperative to check and rectify the existing sewage pipeline. Based on the whole system investigation of 286.4 km sewage pipeline in a district of Nanjing, this paper systematically analyzed the problems existing in the current sewage pipe network from different pipes, pipe diameters and different damage forms. It provides the reference for the investigation and analysis of the current sewage pipeline system in the future and puts forward the design and construction suggestions for the new sewage pipeline.
