彭县的东河水库曾于1962年发生渗漏并导致管涌,由于当时水库蓄水满库,又无放空设施(卧管最大流量只有0.8立方米/秒),在这种情况下,只有采取补漏来防止垮坝。开始用麻袋装粘土抛填,但渗漏量减少甚少。后来由于抛填用的粘土不好取,就只好用库边附近堆放的一堆炭碴抛填,抛填一定数量后,发现渗漏水明显减少,上游库水面由于渗漏水而形成的漩涡也消失了。这样 In 1962, Donghe Reservoir in Pengxian County had been seeping and causing a pipe burst. Since the reservoirs at that time were full of reservoirs and there were no emptying facilities (the maximum flow rate of the lying pipes was only 0.8 cubic meters per second), in this case, Trapping to prevent collapse. Started to throw clay in sacks, but with little reduction in leakage. Later, due to throwing clay used to take badly, we had to use a pile of carbon ballast stacked near the storage side thrown to fill a certain amount of thrown after the leakage was found to significantly reduce the upstream reservoir surface water due to leakage and the formation of vortex Also disappeared such
