湖南沤江花木桥水电站是一座高水头引水式电站,装机容量6万千瓦,1973年底投产。由于地面厂房厂区地形狭窄,并考虑到开关站的需要,厂房只能布置在峡谷出口一段直线河段左岸的小山脊下,因而迫使厂房的纵轴线和尾水渠与河流向成平行布置。此段河宽仅40米,已建围埝占8米,而厂房的尾水渠若按常规至少要10米以上,这就需要研究如何使工程 Hunan Hanjiang Huameiqiao Hydropower Station is a high water head diversion power station, installed capacity of 60,000 kilowatts, put into operation by the end of 1973. Due to the narrow topography of the ground plant site and taking into account the needs of the switchyard, the plant can only be placed under a ridgeline on the left bank of a straight stretch of canyon where the longitudinal axis and tailrace of the plant are forced parallel to the river. This section of the river is only 40 meters wide, has built encircle accounted for 8 meters, and if the plant’s tailrace to be at least 10 meters or more, which need to study how to make the project
