The invention discloses a landscape barrage giving consideration to passage and a construction method. The landscape barrage comprises a weir body and a weir body cross bar river channel; the weir body comprises an open upstream face, a stepped weir face and a weir base; a supporting structure is arranged at the open position of the upstream face and fixed to the weir bottom; a water retaining slope is arranged at the top end of the upstream face; steps are sequentially arranged downwards in the water flow direction of the weir face; the tail end of each step is provided with a protruding water blocking ridge; a water storage surface is formed between the adjacent upper step and lower step; the lower step is provided with an inverted arc-shaped jumping flow ridge; the steps and the jumping flow ridge are framed into empty boxes through reinforced concrete vertical plates; the empty boxes of the steps at the high position are tunnels passing through two banks; and the other empty boxes are all backfilled with fillers. The landscape barrage giving consideration to passage is suitable for an area with the high water storage elevation or an area with the steep topographic condition, a reinforced concrete vertical plate empty box structure can save the concrete consumption and reduce the weight of the weir body, and the overall structure is safe and stable. The upstream face of the barrage intercepts garbage, so that garbage pollution of a downstream river channel can be reduced, the downstream ecological environment is improved, and the tunnel of the barrage can facilitate passing of the two banks during flood.
本发明一种兼顾通行的景观堰坝及构建方法，包括堰体，堰体横栏河道，堰体包括敞开的迎水面、阶梯形堰面和堰座，迎水面敞开处设支撑结构固定于堰底，迎水面顶端设挡水坡；沿堰面水流向依次下设台阶，每级台阶末端均设凸起拦水坎，相邻上、下台阶之间形成蓄水面，低处台阶设反弧形跳流坎；台阶和跳流坎由钢筋混凝土立板框成空箱，高处台阶空箱为通行两岸的隧道，其余空箱内均回填充填物。本发明景观堰坝适用于蓄水高程较高的区域，或者用于地形条件较陡区域，钢筋混凝土立板空箱结构可节省混凝土用量和减轻堰体自身重量，且整体结构安全稳定。堰坝迎水面拦截垃圾可减少下游河道垃圾污染，提升下游的生态环境，洪水时堰坝的隧道可方便两岸的通行。
