When the utility model is in use, by fixing the transverse drainage pipe 4 inside the lining panel 2 and the concrete layer 3, by connecting the drainage hose 6 with the transverse drainage pipe 4, the groove and the concrete layer 3 play the role of slowing down the water flow and wind and waves, the connecting piece 5 can connect the transverse drainage pipe 4 with the drainage hose 6, the fastener 10 can clamp one end of the drainage hose 6 between the fastener 10 and the flange 51, and clamp the other end of the drainage hose 6 between the fastener 10 and the circular pipe 7, so as to further fix the positions of the two ends of the drainage hose 6, and by fixing the floating block 8 on the circular pipe 7, the flap door 9 and the floating block 8 can be always located above the channel water level under the action of the floating block 8, so that the relationship between the channel water level and the external groundwater level is fully considered, and it can be ensured that the flap door 9 is always above the channel water level under any working conditions;

When the external groundwater level is higher than the channel water level, the external groundwater flows through the horizontal drainage pipe 4, the drainage hose 6, the circular pipe 7, the outlet pipe 91 and the connecting pipe 92, and finally breaks the baffle 94 and flows into the channel to achieve gravity flow. When the external groundwater level is lower than the channel water level, as the channel water level rises, the flapper 9 and the float 8 float up under the action of buoyancy, and the baffle 94 contacts one end of the connecting pipe 92 under the action of gravity, which can prevent the water in the channel from flowing back outwards. During the flood season, accompanied by adverse weather factors such as thunderstorms and storms, the risks of manual opening and closing operations, time-consuming, labor-intensive, and expensive operations, as well as the outflow of water from the channel can be avoided. The device is easy to maintain, does not require water level monitoring, and can drain water in a timely manner and automatically.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it.
