摘  要:文章统计了2015—2022年中国城市供水情况,指出当前我国市政供水管网存在严重漏损问题,并从市政供水管网的组成、管材、敷设方式、施工工艺、外部因素、运行维护等方面出发,对泄漏类型及泄漏原因进行了分析研究。在此基础上,介绍了流量法、听音法、相关分析法等9类检漏方法,并结合真实供水管网泄漏案例,综合运用多种方法,开展复杂情况下漏水检测研究。This paper provides statistics on the urban water supply situation in China from 2015 to 2022,point-ing out that there is a serious leakage problem in the municipal water supply networks in China.The types of leaks and their causes are examined from various aspects,including the composition of the municipal water supply network,pipe materials,installation methods,construction techniques,external factors,and opera-tional maintenance.Based on this analysis,the article introduces nine types of leak detection methods,inclu-ding the flow measurement method,acoustic method,and correlation analysis method.It also combines real cases of water supply network leaks to comprehensively apply multiple methods for conducting research on leak detection under complex conditions.
