河湾水电站金属结构方案设计及蓄水安全复核

Metal Structures Design and Storage Safety Verification for Hewan Hydropower Station

针对河湾水电站不同建筑物功能,设计选择不同闸门及启闭型式和布置方案。取水口事故门选用平面定轮钢闸门、溢洪道工作门选用露顶式弧形闸门、放空底孔进口事故门选用潜孔式平面定轮钢闸门,出口工作门选用潜孔式弧形钢闸门,配套选用卷扬或液压启闭方式。安全复核结果表明,金属结构设备选型和结构布置能够满足电站蓄水和安全运用要求。

Hewan hydropower stations in different buildings take different gate type layout scheme.Take the plane fixed-wheels steel sluice gate as the intake emergency gate , the top emersed radial gate as the spillway working gate , the underflow aperture plane fixed -wheels steel sluice gate as the low level outlet intake emergency gate and the underflow aperture radial steel sluice gate as the low level outlet outtake working gate with matching winch or hydraulic hoist way.The storage safety veri-fication results show that the metal structures design can meet the storage and application safety re-quirements.
