| 摘 要： | 广州抽水蓄能电站二期工程(以下简称为广蓄二期)于1998年建成,在上游水道首次充水时,位于上游水道系统的钢筋混凝土岔管上方的排水探洞出现了的高压渗水,最大渗水量达31.78L/s。水道放空后,采用高压化学灌浆和回填高压钢筋混凝土岔管上方的排水探洞,对高压渗水进行了成功处理,目前电站已安全运行了约7年,高岔区的总渗水量一直稳定在2.3L/s。

| Abstract: | The second-stage project of Guangzhou Pumped Storage Power Station was completed in 1998.During the initial water filling of the upstream tunnel,high-pressure water seepage occurred in the drainage tunnel located above the reinforced concrete manifold in the upstream tunnel system,maximal rate of the leakage reaching 31.78 L/s.The leakage was successfully treated through HP chemical grouting and backfilling the drainage tunnel after emptying.Now the power station has been operating safely for about seven years with the leakage rate near the manifold stabilizing at 2.3 L/s. |
