摘要
拉西瓦水电站地处我国西北高寒地区,大坝为高薄拱坝,为满足坝体混凝土对温度控制的要求,采用闭式循环冷水机组进行大坝混凝土冷却。通过认真设计,并经过荷载验算,冷水站安装于主坝坝后的永久马道上。实现了大坝冷却系统自动化,加快了坝体混凝土浇筑的速度,满足了接缝灌浆的要求,提高了冷却水的回收利用率。
Laxiwa Hydropower Station is located in cold areas in Northwest China. The arch dam is high and thin, In order to meet the requirements of dam concrete temperature control, the closed-cycle chiller for concrete cooling is used. After detailed loading calculation, the cold water stations are installed in permanent horse road behind main dam. The application of cold water stations have achieved the automatic operation of dam cooling system, accelerated the speed of concrete pouring, meet the requirements of joint grouting, and improved the recycling utilization of cooling water.
