Shallow flow type ecological barrage structure
The invention relates to a shallow flow type ecological barrage structure. The method is suitable for ecological environment engineering. According to the technical scheme, the shallow flow type ecological barrage structure is installed on a shallow flow type river channel and is characterized in that the shallow flow type ecological barrage structure is provided with a plurality of barrages arranged in the water flow direction in the shallow flow type river channel, and water channels for water flow to pass through are formed in the tops of the barrages. The water channels on the two adjacent barrages on the shallow flow type river channel are arranged in a staggered mode on the cross section of the river channel, and the water channels of the barrages on the shallow flow type river channel are arranged in an S shape on the water surface of the river channel. The drop pond is formed between the two adjacent barrages on the shallow flow type river channel and on the upstream side of the barrage on the downstream side, the flow speed of water in the drop pond on the upstream side of the barrages is low, the water channel for water flow to pass through is formed in the top of the barrages, a migration channel is provided for fishes, the drop pond serves as a good fish habitat, and the drop pond between two adjacent barrages on the shallow flow type river channel has a good ecological function.
本发明涉及一种浅流型生态堰坝结构。适用于生态环境工程技术领域。本发明所采用的技术方案是：一种浅流型生态堰坝结构，安装在浅流型河道上，其特征在于：具有若干沿浅流型河道内水流流向布置的堰坝，所述堰坝的坝顶处具有用于水流通过的水渠。所述浅流型河道上相邻两个堰坝上的水渠在河道断面上成错位布置，浅流型河道上堰坝的水渠在河道水面上成“S”形布置。本发明在浅流型河道上相邻的两个堰坝之间在下游侧的堰坝的上游侧形成跌水塘，堰坝上游的跌水塘中水体流速缓慢，在堰坝的坝顶处开设有用于水流通过的水渠，为鱼类提供洄游通道，使跌水塘作为良好的鱼类栖息地，使浅流型河道上相邻的两个堰坝之间的跌水塘内具有良好的生态功能。
