福建仙游抽水蓄能电站下水库，在导流洞封堵的混凝土塞中专门预埋了供水管道以满足其下游生态放水需要。导流洞在临时闸门挡水的情况下进行封堵施工，至导流洞封堵结束需提升闸门时，水库蓄水深达60m。在深水复杂条件下，采用滑轮组、转向装置、平压充水钢管、专项起吊系统等多项技术，实现了临时闸门的安全提升。

In order to meet the needs of the ecological water in downstream, the reservoir in Fujian Xianyou Pumped-storage Power Station specially pre-buried water supply lines in the concrete plug of diversion tunnel. The diversion tunnel was plugged under the condition of temporary gate retaining water. When the plugging is finished and the hoist gate need to be lifted, the water storage depth of reservoir reached 60m. Under the complex condition in deep water, it took the technology of pulleys, steering gear, flat pressured water steel pipe, special lifting system to realize the safety promotion of the temporary gate.
