The three arc plates 1 are distributed in an annular manner, and a spiral scraper 3 is installed on the outer surface of each arc plate 1. The inner space at the bottom end of the spiral scraper 3 is connected to the corrugated pipe 2, and one end of the corrugated pipe 2 is connected to the inside of the round box 4. A connecting block 5 is installed on the inner surface of each arc plate 1, and a rotating screw on the connecting block 5 is provided. Two screw rods 6 are installed, and the position distance of the connected arc plate 1 can be adjusted by rotating the screw rods 6 to meet the cleaning needs of foundation pits with different apertures. The screw rods 6 are threadedly connected to the screw holes 701 on the strip blocks 7, and the bottom end of the strip blocks 7 is fixedly installed on the corresponding position of the top surface of the round box 4. A pipe shaft 10 is installed in the middle position of the top of the round box 4, and a transfer pipe 8 is installed around the strip hole 1001 on the pipe shaft 10, and a suction and discharge hose 11 is installed in the middle of the transfer pipe 8.

[0023] The ports at both ends of the transfer tube 8 are rotatably sealed and connected to the corresponding parts of the pipe shaft 10 through bearings 9, which helps the transfer tube 8 to be stationary relative to the pipe shaft 10.
