摘　　要：为提高漏水检测效率,满足城市高速发展对供水管网漏损控制的要求,通过实际项目案例的开展探索出了一种检测新模式-“外水测算+供水管网漏水检测模式”。该模式可以利用外水测算技术快速掌握漏水严重区域,再通过采用主动探漏方式,运用综合性检测方法对区域内供水管网进行漏水检测,可实现快速降低城市供水管网漏损率,切实减少国民经济损失。In order to improve the detection efficiency of water leakage and meet the requirement of water supply network leakage control by the rapid development of the city,through the actual project,a new detection mode was explored-“external water measurement+water supply network leakage detection mode”.In that mode,the area with serious water leakage could be grasped quickly by utilize the external water measurement technology,and then adopted sctive leak detection way combined with comprehensive detection method to carry out leakage detection of regional water supply pipe nets.It could realize the rapid reduction of the water loss rate of urban water supply pipe network and effectively reduce the loss of national economy.
