Method for preventing and treating debris flow in canyon mountainous area with high vegetation coverage rate
The invention discloses a high vegetation coverage rate canyon mountainous area debris flow control method which is characterized in that before control, a combined dam is arranged in a gully, the combined dam comprises a grating dam and a blocking dam which are sequentially arranged from top to bottom along the gully terrain, and the grating dam comprises concrete supporting columns arranged at intervals in the width direction of the gully; a blocking net is connected between every two adjacent concrete supporting columns, and the grid width of each blocking net is 0.5-1 m. The method has the advantages that serious threats of debris flow in high vegetation coverage areas of alpine canyons to the downstream can be effectively reduced, all levels of blocking dams can be fully utilized, and desilting work in front of the dams is facilitated.
本发明公开了一种高植被覆盖率峡谷山区泥石流防治方法，其特征在于，防治前，先在沟谷内设置组合坝，所述组合坝包括沿沟谷地形由上向下依次设置的格栅坝和拦挡坝，所述格栅坝包括沿沟谷宽度方向间隔设置的混凝土支柱，相邻两个所述混凝土支柱之间连接有拦挡网，所述拦挡网的网格宽度为0.5～1米。本发明具有既能有效降低高山峡谷高植被覆盖率地区泥石流对下游造成严重威胁，又能充分利用各级拦挡坝且便于坝前清淤工作等优点。
