堤坝管涌渗漏检测仪是利用“伪随机流场法”原理设计制造的,它能快速查明堤坝渗漏或管涌的进水口位置,并为抗洪抢险现场快速决策和汛后整治提供依据。文中结合水库大坝渗漏隐患的探测来介绍堤坝管涌渗漏检测仪的工作原理及其应用效果。 The dyke pipe leakage detector is designed and manufactured by the principle of “pseudo-random flow field method”, which can quickly find out the water inlet of the dyke leakage or piping, and provide the basis for fast decision-making and after-flood regulation of flood control and rescue site . In this paper, the principle of leakage detector of dyke pipe and the application effect are introduced according to the detection of reservoir dam leakage.
