峡口水利枢纽泄水系统的金属结构设计

Design of the Metal Structures of the Water Discharge System in Xiakou Hydro-junction

峡口水利枢纽拦河坝为拱坝,采用坝顶溢流和坝体中孔的泄水方式。分别介绍了坝顶溢流孔的闸门、中孔事故检修闸门、工作闸门及其启备机的设计要点,包括结构布置、运行方式、计算结果等内容。电站运行结果表明,各类闸门及启闭设备运行良好。

In the arch dam of the Xiakou Hydro-junction,crest overflow outlets and middle-level outlets are adopted as the water discharge system. Key points on the design of the crest overflow gates,emergency and working gates of the middle-level outlets and the gate hoists are introduced,including the structure arrangement,operation modes and design calculations. Practical operation of the hydropower station shows that the gates and hoists are of perfect working conditions.
