Lower reservoir water inlet/outlet with rock plug and rock stem combined water retaining function and construction method
A rock mass, close to one side of a river channel, around a mountain provided with a tailrace tunnel is sequentially divided into an overwater rock mass, a water level amplitude variation area rock mass and a total rock stem from top to bottom, the total rock stem is located below the outer side of the water level amplitude variation area rock mass, the bottom of the outer side of the total rock stem is a partial rock stem, and the partial rock stem is located below the water level amplitude variation area rock mass. A water inlet/outlet of the tailrace tunnel is located at the bottom of the water level variable-amplitude area rock mass, the end portion, close to the water level variable-amplitude area rock mass, of the tailrace tunnel is a rock plug, the overwater rock mass is located above the normal water storage level of the built lower reservoir, the top elevation of the water level variable-amplitude area rock mass is basically the same as the normal water storage level elevation of the built lower reservoir, and the bottom elevation is located below the dead water level. The total rock stem crest elevation is located between the normal water storage level and the dead water level, and the partial rock stem crest elevation is slightly higher than the dead water level. The construction risk of the built water inlet/outlet of the lower reservoir is reduced, meanwhile, the work amount is reduced, investment is saved, and great economic benefits are achieved.
本发明公开了一种岩塞岩梗联合挡水的下库进/出水口，设置有尾水隧洞的山体周围临近河道一侧的岩体由上至下依次划分为水上岩体、水位变幅区岩体和总岩梗，总岩梗位于水位变幅区岩体的外侧下方，总岩梗的外侧底部为部分岩梗，尾水隧洞的进/出水口位于水位变幅区岩体的底部，尾水隧洞临近水位变幅区岩体的端头部分为岩塞，水上岩体位于已建下库正常蓄水位以上，水位变幅区岩体顶高程与已建下库正常蓄水位高程基本相同、底高程位于死水位以下，总岩梗顶高程位于正常蓄水位和死水位之间，部分岩梗顶高程略高于死水位。本发明降低了已建下库进/出水口的施工风险，同时减少了工程量，节省了投资，具有较大经济效益。
