The present application has the effect of reducing the flow of silt and gravel in the water flow upstream of the gate to the downstream.

[0004] The existing sand retaining board can intercept the sand in the water flow, but there will be a small amount of garbage and dead branches fallen on both sides of the river in the river. The sand retaining board will intercept the garbage in the river at the same time as intercepting the sand. For a long time, the sand retaining board will be blocked and the river water will not flow. The garbage will also settle after a long time of soaking. The large volume of the garbage makes the transmission pipe unable to transmit effectively.
