摘　　要：对安阳市老城区３９ｋｍ自来水供水管线进行普查检漏。使用自行研制的ＰＣＬ－Ⅱ管线定位仪和ＴＬ－Ⅱ检漏仪，采用水压普查检漏法，声测检漏等方法共查明各种明、暗漏５８处，同时给出了供水管网水压分布和渗漏分区。其结果有利于供水管网的管理运行，维修改造，对减少水资源损失及防止其次生灾害造成的危害起到了良好的作用。The leak detection of the water supply network system in the old urban area of Anyang has been performed. In this work, We used our self-made PCL-Ⅱ pipeline localiger and TL-Ⅱ leak detector and adopted the method of general investigation of water pressure as well as the method of leak detection by acoustic wave tracking.It has been established that, there are 58 overt and covert leakes spots in the old urban area of Anyang.In this paper, the distribution of water pressure and the distribution of the leakage zone of the water supply network system have been given. The results are benefit to administration repairation of water supply system.This work can reduce the lose of water resources and prevente the occurrence of secondary disasters.
