Mountain torrent disaster reduction ecological dam type structure system and construction method thereof
The invention provides a mountain torrent disaster reduction ecological dam type structure system and a construction method thereof. The ecological dam type structure system comprises a dam bottom water passing channel, a dam body structure and an early warning monitoring system. The method is suitable for ecological and flood control requirements of small and medium-sized river basins in valley areas. The dam bottom water passing channel uses the original river channel, the river is not blocked, and the fish migration path is not changed; local materials in valleys are fully utilized, and dam types such as rock-fill concrete, cemented sand gravel and cemented soil are adopted; and a dangerous case monitoring system is arranged to realize automatic early warning and alarming. And in consideration of normal operation and extreme flood working conditions, the stress and stability of the dam body structure are analyzed. The original river connectivity is not blocked, the original river ecological environment is protected against damage, and the ecological benefits are remarkable; when the flood comes, the flood flows through the river channel at the dam bottom, the upper dam body blocks water, and if the flood exceeds the elevation of the dam crest, the dam crest can overflow.
本发明提供了一种山洪灾害减灾生态坝型结构系统及其施工方法，生态坝型结构系统包括：坝底过水通道、坝体结构及预警监测系统。本发明适用于山谷地区中小流域河流的生态及防洪要求。坝底过水通道，利用原有河道，不阻断河流，不改变鱼类洄游路径；充分利用山谷中当地材料，采用堆石混凝土、胶结砂砾石、胶结土等坝型；设置险情监测系统，实现自动预警、报警。考虑正常运行和极端洪水工况，对坝身结构受力及稳定性进行分析。本项发明不阻断原有河流连通性，保护原有河流生态环境不受损害，生态效益显著；可拦蓄洪水、泥石流，削峰均化，洪水来临时通过坝底河道过流，上部坝身挡水，若洪水超过坝顶高程，则可坝顶溢洪。
