The invention discloses a pool type overtopped dam, and belongs to the field of dams of water conservancy projects. At present, multiple types of dams exist, and the defects include fish migration blocking behaviors, difficult floating discharge, much sediment deposited in a reservoir and the like. More than one U-shaped sand flushing channel penetrating through upstream and downstream is arranged, each U-shaped sand flushing channel reaches the bottom of a river valley, and a strip-shaped pier is arranged between every two adjacent sand flushing channels; upper and lower gates inclined to the middle of the dam are correspondingly arranged on the upstream and downstream of each sand flushing channel, and a water pool is formed between each group of upper and lower gates; the top ends of a plurality of groups of upper and lower gates can overflow and drain floats; a plurality of groups of upper and lower gates can be positioned and lifted so as to release reservoir capacity and scour sediment in the reservoir, and if the water level difference is small or disappears, the fish migration behavior is recovered.
本发明是水池型漫水坝，属于水利工程的水坝领域。当前，水坝有多种类型，不足之处有有阻挡鱼类洄游行为，排漂难问题、水库淤积泥沙多问题等。本发明，有一条以上贯通上下游的U形冲沙道，每条深度到河谷底部，两条相邻冲沙道之间是条形墩；每条冲沙道的上下游有对应向水坝中间倾斜的上下闸门，每一组上下闸门之间就形成了水池；若干个组上下闸门顶端，都可以漫水、排漂；若干个组上下闸门能定位提升，以进行释放库容、冲刷水库淤积泥沙，如果水位差小或消失，就恢复了鱼类洄游行为。
