Landscape drop weir structure suitable for constructing bottom hole type fishway
The invention relates to a landscape drop weir structure suitable for constructing a bottom hole type fishway, and is suitable for the technical field of water ecological management. According to the technical scheme, the landscape drop weir structure suitable for constructing the bottom hole type fishway is characterized by comprising a weir body, a stilling pool and a flow state creating area which are sequentially arranged in the water flow direction, wherein the downstream side of the weir body is provided with multi-stage drop, the bottom hole type fishway communicating with the upstream and the downstream of the weir body is arranged in the weir body, a gate is arranged in the weir body, and a plurality of loose stones are arranged at the bottom of the flow state creating area in a staggered mode. The drop height of the multi-stage drop ranges from 20cm to 40cm. A plurality of river pebbles capable of forming a rolling water overflowing effect are embedded in the surface of the multi-stage drop. The water storage depth of the stilling pool is larger than or equal to 50cm. The minimum loose stone particle size of the loose stones is determined according to the maximum overflowing flow speed and is larger than or equal to 40cm, the loose stones are arranged in a staggered mode, and a natural flow state with the high flow speed and the low flow speed alternating is constructed.
本发明涉及一种适用构建底孔型鱼道景观跌水堰结构。本发明适用于水生态治理技术领域。本发明的技术方案为一种适用构建底孔型鱼道景观跌水堰结构,其特征在于:具有沿水流方向依次设置的堰体、消力池和流态营造区,其中堰体的下游侧为多级跌水,堰体内设有连通其上、下游的底孔型鱼道并配有闸门,流态营造区底部错落布置有若干散石。所述多级跌水的跌坎高度介于20~40cm之间。所述多级跌水表面嵌有能形成滚水过流效果的若干河卵石。所述消力池蓄水深度大于等于50cm。所述散石最小散石粒径根据最大过流流速确定且大于等于40cm,散石采用错缝布置,构造高低流速交替的自然流态。
