A water storage chamber 8 is provided at the part, and a support rod 9 is movably connected to the inner wall of the water storage chamber 8. A second slide groove 10 is provided on the inner wall of the retaining wall body 1, so that the side wall 2 and the column 3 can be quickly connected. A deep socket 11 is inserted at the bottom of the column 3, and a shallow socket 12 is provided on one side of the deep socket 11 to facilitate the subsequent connection of the gate 6 and avoid water seepage. A second slider 13 is fixedly connected to one side of the side wall 2, and a third slide groove 14 is provided on the other side of the side wall 2, a third slider 15 is provided on one side of the column 3, and a first slide groove 16 is provided on the other side of the column 3.

[0029] Specifically, the retaining wall body 1, the side wall 2, and the gate 6 are all made of foam concrete material. The gate 6 has a T-shaped appearance. The outer walls of the retaining wall body 1, the side wall 2, and the gate 6 are wrapped with plastic plates, so that the device can float on the water surface when there is no water in the water storage chamber 8.

[0030] Specifically, the hydraulic pump 4 and the telescopic rod 5 form a lifting structure, and there are two sets of lifting structures. The lifting structure drives the gate 6 to open and close, so as to facilitate the discharge of water from the water storage chamber 8 when it is not used later.

[0031] Specifically, the inner diameters of the second slide groove 10, the first slide groove 16, and the third slide groove 14 match the outer diameters of the first slider 7, the second slider 13, and the third slider 15, and the outer diameters of the column 3 and the gate 6 match the inner diameters of the deep plug hole 11 and the shallow plug hole 12.
