FLOW-DOWN MATTER CAPTURE BODY AND FOREST CONSERVATION METHOD

摘要

To provide a flow-down matter capture body which dispenses with a foundation work and captures stone and wood flowing together with water, and passes water therethrough.SOLUTION: A flow-down matter capture body 1 which is mounted on the ground surface and captures a flow-down matter such as rock and drift wood flowing form the upstream side is composed of a regular tetrahedron formed in a regular triangle frame shape by six frame members 10, any one surface of four frame-shaped surfaces is used as a bottom surface frame part mounted on the ground surface, and other three surfaces are used as a capture surface frame part that forms a capture surface of a flow-down matter projecting upward to the bottom surface frame part.SELECTED DRAWING: Figure 1
