  • Patent number: 9834898
    Abstract: A debris flow drainage channel is provided. The debris flow drainage channel is applicable to debris flows with large gully bed longitudinal slopes. The debris flow drainage channel has an upstream step section and a downstream step section. The debris flow drainage channel also has a step pool disposed between the upstream step section and the downstream step section. The pool section has a cable net cage bottom protection, a cable net cage buffer layer and block stones.
    Type: Grant

    Abstract: A debris flow drainage channel is provided. The debris flow drainage channel is applicable to debris flows with large gully bed longitudinal slopes. The debris flow drainage channel has an upstream step section and a downstream step section. The debris flow drainage channel also has a step pool disposed between the upstream step section and the downstream step section. The pool section has a cable net cage bottom protection, a cable net cage buffer layer and block stones. When the debris flow drainage channel is applied to the debris flows with large gully bed longitudinal slopes, the flow velocity of the debris flow can be controlled to ensure that the scouring of the debris flow body at a bottom of the channel can be controlled. As a result, normal drainage function of the debris flow drainage channel can be guaranteed and maintenance cost can be reduced.
