A gabion check dam structure for debris flow treatment is continuously provided with a gabion check dam, a drainage groove and a drainage channel from upstream to downstream. The gabion check dam is composed of multiple layers of gabion gabions, one layer is arranged underground, N layers are arranged on the ground, the heights of all the layers on the ground are equal, the gabion gabions are arranged in the shape of a Chinese character'pin ', the interfaces are trapezoidal, and dam abutments at the two ends are embedded into bank slopes. An overflow groove is formed in the middle of the gabion check dam; the drainage groove is composed of grouted rubble flow guide dams on the two sides and a rubble concrete anti-impact rib wall in the middle. The drainage channel is arranged at the position where the width of the downstream gully of the gabion check dam is obviously increased and is composed of gabions, and the elevation of the channel top is equal to that of the bottom of an overflow groove of the gabion check dam. By means of the structure, gully bed erosion can be controlled, the stability of a gully and a bank slope can be kept, solid matter in debris flow can be intercepted, the flow and density of discharged debris flow can be reduced, the peak flow of downstream debris flow can be adjusted, the pressure of downstream drainage engineering can be relieved, and the harm of debris flow to the downstream can be relieved.
一种用于泥石流治理的石笼谷坊结构，由上游至下游，连续地设有石笼谷坊、排导槽、排导渠；石笼谷坊由多层宾格石笼构成，地下设有1层，地上设有N层，地上每层高相等，宾格石笼呈“品”字排布，界面为梯形，两端坝肩嵌入岸坡；石笼谷坊中间设有溢流槽；排导槽由两侧的浆砌石导流堤坝和中间的毛石混凝土防冲肋墙构成；排导渠设置在石笼谷坊下游沟谷宽度增大明显处，由宾格石笼构成，渠顶标高与石笼谷坊的溢流槽底部标高相等。本发明通过上述结构，可以控制沟床侵蚀，保持沟道及岸坡稳定，拦截泥石流中固体物质，削减下泄的泥石流流量和密度，调节下游泥石流洪峰流量，减轻下游排导工程的压力，减轻泥石流对下游的危害。
