Debris flow drainage and drag reduction culvert structure based on bionics
The debris flow drainage and drag reduction culvert structure based on bionics comprises a culvert body, an inlet and an outlet, scale-shaped drag reduction structures are laid on the inner wall face of the culvert body, and all the inner wall faces of the whole culvert body are paved with the scale-shaped drag reduction structures; the scale-shaped resistance reduction structure is formed by continuously laying and splicing a plurality of scale units, each scale unit is provided with a top, a bottom and a waist, the top is provided with an outwards-convex arc-shaped top side end face, the bottom is provided with an inwards-concave arc-shaped bottom side end face, and the waist is provided with two symmetrically-arranged inwards-concave arc-shaped waist side end faces. Every two adjacent scale units are seamlessly spliced with each other; the bottom and the top of each scale unit are arranged in the flow direction of debris flow, and the end face length of the end face of the outwards-convex arc-shaped top side is larger than that of the end face of the inwards-concave arc-shaped bottom side. The thickness of the bottom of each scale unit is smaller than that of the top, and the thickness from the bottom to the top changes uniformly. Debris flow deposition and blockage can be avoided or reduced.
本发明涉及一种基于仿生学的泥石流排导减阻涵洞结构，包括洞身、入口和出口，洞身的内壁面上铺设有鳞片形减阻结构，鳞片形减阻结构铺满整个洞身的所有内壁面；其中，鳞片形减阻结构由多个鳞片单元连续铺设拼接而成，鳞片单元具有顶部、底部和腰部，顶部具有一个外凸弧形顶侧端面，底部具有一个内凹弧形底侧端面，腰部具有两个对称布置的内凹弧形腰侧端面，所有相邻的两个鳞片单元均为无缝拼接；每一个鳞片单元的底部和顶部沿着泥石流流向布置，外凸弧形顶侧端面的端面长度大于内凹弧形底侧的端面长度；每一个鳞片单元的底部的厚度小于顶部的厚度，且底部至顶部的厚度均匀变化。本发明能够避免或减小泥石流淤积和堵塞。
