The invention discloses a revetment diversion method for a high-frequency debris flow. In the revetment diversion method, stacked gabions and vertical reinforcements deeply planted in a gully bed are comprised, and the gabions and the vertical reinforcements are mutually fused to form flexible longitudinal dikes or spur dikes; the flexible longitudinal dikes are arranged in parallel to a flow direction and along a gully bank; the spur dikes stretch into a gully centre and are arranged at an acute angle with the flow direction; the vertical reinforcements are made of micro steel pipe piles or H-shaped steel or rood piles which are arrayed and distributed in a close-triangle shape and along the axial direction of the longitudinal dikes, and are connected with the gabions by virtue of steel strands, and lower burying depths are determined by an erosion depth of the debris flow; and each adjacent spur dikes are distributed at a gully side along the flow direction at a certain interval to form a spur dike group for revetment diversion. The revetment diversion method disclosed by the invention is fast to construct, and high in erosion resistance and geography adaptability; local materials can be used, thus the construction cost is remarkably reduced; the threat of the debris flow on a loose gully bank and gully side protection object is rapidly reduced; and the revetment diversion method is suitable for emergency rescue and safety flood protection working for the high-frequency debris flow in the loosely-piled gully bank and gully side protection object.
