CN102587330A 一种下游落差式陡坡泄槽弧形迷宫堰 无效 - 驳回

一种下游落差式陡坡泄槽弧形迷宫堰
摘要：
本发明涉及一种迷宫堰，特别是一种下游落差式陡坡泄槽弧形迷宫堰，包括沿水流方向依次衔接的上游引渠、迷宫堰底板和迷宫堰下游泄槽，迷宫堰底板为弧形迷宫堰，弧形迷宫堰两端向沿水流方向斜向伸出有水坝，弧形迷宫堰两端水坝呈外八字，其特征在于：在迷宫堰底板顶面有弧形迷宫堰堰体，弧形迷宫堰堰体从迷宫堰底板弧形一端到另一端形成弧形折叠。它解决现有技术中由于下游出现淹没流态，泄流能力降低的缺陷。
摘要（英）：

The invention relates to a labyrinth weir, in particular to an arc-shaped labyrinth weir with a downstream dropping slope chute. The arc-shaped labyrinth weir provided by the invention comprises an upstream approach channel, a labyrinth weir bottom plate and a labyrinth weir downstream chute connected in a water flow direction; the labyrinth weir bottom plate is an arc-shaped labyrinth weir; dams slantly extend out from two ends of the arc-shaped labyrinth weir in the water flow direction; and the dams at the two ends of the arc-shaped labyrinth weir are V-shaped. The arc-shaped labyrinth weir provided by the invention is characterized in that an arc-shaped labyrinth weir body is arranged on the top face of the labyrinth wire bottom plate and is folded in an arc shape from one end of the arc-shaped labyrinth weir bottom plate to the other end of the arc-shaped labyrinth weir bottom plate. With the adoption of the arc-shaped labyrinth weir provided by the invention, the disadvantage that the discharge capacity is reduced due to the submerged flow state at the downstream in the prior art is avoided.
