稻城河日霍水电站,首部枢纽布置方案与施工导流结合,经混凝土溢流堰与混凝土闸坝方案比选后,最终确定采用混凝土闸坝布置方案。闸坝方案首部枢纽由3孔泄洪闸、1孔冲沙闸、发电洞进口闸及两岸混凝土重力坝连接坝段组成;基础防渗采用水平铺盖加悬挂式防渗墙布置方案,确保渗流稳定满足设计要求。
Daocheng River Rihuo Hydropower Station, the first hub layout and construction diversion plan combined by the concrete weir and concrete dam program comparison, and ultimately determine the use of concrete dam layout program. The first dam of the dam project consists of a 3-hole sluice gate, a 1-hole red sand sluice gate, a power generation hole inlet gate, and a connecting dam section of both sides of the concrete gravity dam. The foundation seepage prevention adopts horizontal laying and suspended hanging seepage prevention wall arrangement to ensure that the seepage flow is stable Design requirements.
