寒冷地区的面板坝水位变化区的接缝止水最容易产生冰冻破坏,电站运行单位每年都要花费大量资金修复面板表面接缝止水,现采取工程措施对面板表面接缝止水加以保护,确保冬季水位变化区的接缝止水不会产生冰冻破坏,降低电站运行成本。
寒冷地區的麵闆壩水位變化區的接縫止水最容易產生冰凍破壞,電站運行單位每年都要花費大量資金脩複麵闆錶麵接縫止水,現採取工程措施對麵闆錶麵接縫止水加以保護,確保鼕季水位變化區的接縫止水不會產生冰凍破壞,降低電站運行成本。

In cold region, the CFRD joint waterstop in water level change range easily fails by frozen occurrence.Each year, it costs a lot to repair the frozen waterstop.Through the engineering measures to protect the surface joint waterstop, the frozen failure in winter is avoi-ded and the operation cost is reduced accordingly .
