Branch river channel energy dissipation desilting diversion hydraulic construction system
The invention discloses a tributary river channel energy dissipation desilting diversion hydraulic construction system which is characterized by comprising a high platform, a stilling basin, a low platform and a diversion embankment which are sequentially connected from the upstream end to the downstream section of a tributary river channel, river banks on the two sides of the high platform are designed to be widened in a splayed mode in the downstream direction, and the downstream end of the high platform is connected with a steep slope of the stilling basin; the lower end of the abrupt slope is connected with a pool body of the stilling pool, the downstream end of the pool body of the stilling pool is connected with the low platform, the upstream end of the low platform is higher than the bottom position of the pool body of the stilling pool to form the pool body, and the flow guide embankment is consistent with the main stream at the intersection in water flow direction and fixedly arranged at the connection position of the upstream side of the branch stream and the main stream. The lower half part of the low platform is positioned between the diversion embankment and the opposite downstream side bank of the tributary. According to the method, the influence of the branch river channels on the canal main stream can be better avoided, and the water regimen stability of the canal main stream can be better guaranteed, so that the navigation safety and the ecological environment stability at the intersection are improved.
本发明公开了一种支流河道消能沉沙导流水工建筑系统，其特征在于，包括从支流河道上游端到下游段依次衔接设置的高平台、消力池、低平台和导流堤，高平台两侧河岸向下游方向呈八字形扩宽设计，高平台下游端和消力池的陡坡衔接，陡坡下端衔接消力池的池体，消力池的池体下游端衔接低平台，低平台上游端高出消力池的池体底部位置以形成池体，所述导流堤和交汇处干流的水流方向一致并固定设置在支流上游侧和干流相接位置处，使得导流堤和支流河道上游侧相交呈钝角，所述低平台下半部分位于导流堤和相对的支流下游侧边岸之间。本发明能够更好地避免支流河道对运河干流的影响，更好地保证运河干流的水情稳定，以提高通航安全性和交汇处生态环境稳定性。
