摘要
介绍了在讨赖河流域已建水电站上采用虹吸管替代增设生态放水孔设计的情况。通过虹吸管水力计算,确定虹吸管的流量以及虹吸管顶部的允许最大安装高程。实践证明,虹吸管可以在不破坏原水电站坝体结构及设备的情况下,有效地解决向下游河道输送生态流量的问题,具有造价低,施工期短,使用灵活,管理、维护方便等优点。
Application of the siphon pipe instead of the ecological outlet additionaly built in the existing hydropower stations in the Taolai river basin is described. Through the hydraulic computation of the siphon pipe,discharge for the siphon pipe and the maximum allowable installation elevation of the siphon top are determined. The practice proves that the siphon pipe,in condition of without damaging the dam structure and equipment of the existing hydropower stations,can effectively deliver the ecological discharge to the downstream river course. It features lower cost,short construction period,flexible operation,convenient management and maintenance,etc.
