Stepped straw check dam for treating erosion gully

The utility model discloses a stepped straw check dam for treating an erosion gully, and relates to a straw check dam for treating the erosion gully. The utility model aims to solve the technical problems of frost heaving, limited material source, long transportation distance, high manufacturing cost, large annual yield of straws, few treatment methods and low utilization rate of the conventional check dam. The stepped straw check dam is large in straw consumption and low in manufacturing cost, straw blocks are formed by reprocessing straw, the straw degradation rate is slowed down, the stepped straw check dam becomes a novel check dam construction material, the straw blocks are connected and fixed into a whole through the hollow iron wire cage, and therefore the straw check dam is convenient to use. The straw blocks are of flexible structures, so that the influence of freeze thawing, sedimentation and the like on the straw check dam is reduced, the service life of the check dam is prolonged, and meanwhile co
