With the help of the drainage pump 1 and the weight of the structure itself, the mesh plate 8 can always be in contact with the bottom of the foundation pit, so that the water at the bottom of the foundation pit can be pumped out efficiently, thereby increasing work efficiency.

[0023] It should be noted that the operation of the control motor 13 causes the rotating shaft 14 to drive the cam 15 to rotate, and the elastic effect of the spring 12 on the movable plate 11 causes the cam 15 to rotate, driving the movable plate 11 to move back and forth in the vertical direction, and the action of the movable block 10 to continuously excavate the bottom of the foundation pit which is on the same plane as the stabilizing bar 6.

[0024] In an optional embodiment: the lower end of the stabilizing rod 6 and the lower end of the movable block 10 are both conical, and the stabilizing rod 6, the mesh plate 8 and the lower wall of the movable block 10 are on the same horizontal plane.
