Flexible emergency water retaining and flood discharging embankment for small and medium-sized reservoir retaining dams
The flexible emergency water retaining and flood discharging embankment comprises a water retaining sub-embankment arranged in the length direction of the water retaining dam, a flood discharging opening is formed in the water retaining sub-embankment, a flexible flood discharging channel arranged along the downstream face of the water retaining dam is connected to the flood discharging opening, and a plurality of water stopping energy dissipation ridges are evenly arranged in the flexible flood discharging channel at intervals. And an anti-impact gabion net gabion filled with riprap is arranged at the lower port of the flexible flood discharge channel. In the flood prevention and control process of the small and medium-sized reservoirs, the emergency water retaining sub-embankments and the overflow type emergency spillway can be rapidly constructed by utilizing the buoyancy type water retaining dam, the defense purpose of rapid flood discharge of over-standard flood of the small and medium-sized reservoirs is achieved, and the flood prevention and discharge safety of the reservoirs is ensured. The buoyancy dam, the protective layer cloth liner and the waterproof canvas are all disposable, the supports (the water retaining supports, the water retaining rods, the flow guide supports, the flow guide supporting rods, the transverse pressing rods and the longitudinal pressing rods) can be recycled, and the cost of one-time rescue is low. And large-scale popularization and application can be realized.
本发明公开了用于中小型水库挡水坝的柔性应急挡水泄洪堤，包括沿挡水坝长度方向设置的挡水子堤，挡水子堤上开设有泄洪口，泄洪口处连接有沿挡水坝背水面设置的柔性泄洪道，柔性泄洪道内均匀间隔设有若干个雍水消能坎，柔性泄洪道下端口处设有装有抛石的防冲格宾网石笼。本发明在中小型水库防汛度汛过程中，利用浮力式挡水坝可快速构筑应急挡水子堤和漫溢式应急溢洪道，实现中小型水库超标准洪水快速泄洪的防御目的，确保水库防汛行洪安全。本发明中的浮力坝、防护层垫布、防水帆布均为一次性使用，支架（挡水支座、挡水杆、导流支座、导流支杆、横向压杆和纵向压杆）可重复循环使用，单次抢险的成本低。可大规模推广应用。
