电站进水口、溢洪道进口及坝前导漂设施。 溢洪道兼作漂木道,采用面流漂木过坝。地下厂房尾水铁路、公路两用拱桥 常年洪水时桥面上需过水,最大水深达2米。由于桥梁结构受力情况复杂,故采用了无碴、无枕、允许桥面上过水的钢筋混凝土拱形桥的结构形式,跨度64米。 Power station inlet, spillway import and dam leading drift facilities. The spillway doubles as a drift road, using surface floats across the dam. Underground plant tailrace railway, highway dual-use arch bridge perennial flooding required water, the maximum depth of 2 meters. Due to the complex structure of the bridge structure, it adopts the structural form of ballastless, pillowless and reinforced concrete arch bridges that allow water to pass over the bridge deck, with a span of 64 meters.
