Abstract

This utility model discloses a slope runoff buffering and sediment filtration device, relating to the field of water guiding equipment technology. It includes an arc-shaped water guiding plate, with a U-shaped half-pipe fixedly connected to the bottom end of the arc-shaped water guiding plate. V-shaped grooves are respectively provided on the left and right sides of the arc-shaped water guiding plate, and an arc-shaped filter plate is fixedly connected to the top of the U-shaped half-pipe. This slope runoff buffering and sediment filtration device, by setting up the arc-shaped water guiding plate, U-shaped half-pipe, and V-shaped grooves, allows rainwater to flow down the slope and directly enter the U-shaped half-pipe along the arc-shaped water guiding plate. The arc-shaped structure inside the U-shaped half-pipe mitigates the impact of the water flow and guides it to both sides into the V-shaped grooves, where it is concentrated and discharged. Multiple sets of arc-shaped water guiding plates and U-shaped half-pipes work together to form a tiered structure, progressively reducing runoff. Furthermore, the overall cost is low and deployment is quick, achieving the function of buffering runoff and accelerating drainage, thus solving the problem of rapidly alleviating slope runoff.
