When the output shafts of the two electric cylinders 301 extend, the two mud suction pipes 403 pass through the two mud entry holes 1021, so that the two mud suction pipes 403 move to the bottom of the road and bridge pile foundation hole. At the same time, the two mud entry holes 1021 are sealed; when the two mud suction pumps 401 are working, the mud at the bottom of the road and bridge pile foundation hole enters the two mud suction pumps 401 through the two mud suction pipes 403, and then is discharged through the two mud discharge pipes 404.

The two circular guide shafts 601 and the two conical insertion heads 603 are soft and can be inserted into the mud collecting barrel 101. When the mud collecting barrel 101 is taken out and the two conical insertion heads 603 are in contact with the ground, the ground supports the two conical insertion heads 603, so that the sealing baffle 602 can be automatically opened when the mud collecting barrel 101 moves downward (because the external ground is hard, the two circular guide shafts 601 and the two conical insertion heads 603 cannot be inserted), realizing the automatic discharge of mud in the mud collecting barrel 101 and improving the cleaning efficiency of the pile foundation holes of roads and bridges.

During the falling process of the mud collecting barrel 101, the mud in the road bridge pile foundation hole can enter the top of the mud supporting plate 102 through the two mud inlet holes 1021.

When the driving frame 302 drives the two driving inclined plates 303 and the two limiting vertical plates 304 to move downward, the two driving inclined plates 303 can squeeze the two limiting plug rods 501, so that the two limiting plug rods 501 are inserted into the side walls of the road bridge pile foundation hole, thereby improving the stability during mud suction; the output shafts of the two electric cylinders 301 are retracted by half, and the two limiting plug rods 501 can be automatically reset under the action of the two reset springs 502. At the same time, the two mud suction pipes 403 are not in contact with the two mud entering The holes 1021 are separated to prevent the mud inside the mud collecting barrel 101 from flowing out when the mud collecting barrel 101 moves upward; the mud collecting barrel 101 is then taken out from the road and bridge pile foundation hole by a crane; the mud collecting barrel 101 is moved to the mud discharge area by a crane, and the mud in the mud collecting barrel 101 is waited for to be completely discharged through the four mud discharge holes 1011.

the sludge discharge pipe (404) is fixedly mounted on the top of the sludge suction pump (401); The limiting unit (5) comprises: a limiting rod (501) and a return spring (502); the limiting rod (501) is slidably mounted on the mud collecting tube (101), and the outer end of the limiting rod (501) is provided with a chamfer, and the inner end of the limiting rod (501) is provided with a rounded corner; the limiting rod (501) and the limiting vertical plate (304) are located in the same central plane, and the inner end of the limiting rod (501) is in contact with the limiting vertical plate (304); the return spring (502) is mounted on the outside of the limiting rod (501); The sealing unit (6) comprises: a circular guide shaft (601), a sealing baffle (602) and a conical insertion head (603); there are two circular guide shafts (601) in total, and the two circular guide shafts (601) are slidably mounted on the mud support plate (102); the sealing baffle (602) is fixedly mounted on the top of the two circular guide shafts (601), and the outer side of the sealing baffle (602) contacts the inner wall of the mud collection tube (101), and the sealing baffle (602) and the mud discharge hole (1011) are located in the same central plane; there are two conical insertion heads (603) in total, and the two conical insertion heads (603) are fixedly mounted on the bottom of the two circular guide shafts (601); When in use, four U-shaped lifting ears (103) are connected to the hooks on the crane through steel wire ropes, and then the mud collecting barrel (101) is placed in the road bridge pile foundation hole through the crane; before the mud collecting barrel (101) approaches the bottom of the road bridge pile foundation hole, the motor (202) is turned on to wait for the mud collecting barrel (101) to fall to the bottom of the road bridge pile foundation hole. During the falling process of the mud collecting barrel (101), the mud in the road bridge pile foundation hole can enter the top of the mud supporting plate (102) through the two mud inlet holes (1021). When the motor (202) is working, the drilling shaft (203) drives the drilling drill bit (204) to rotate, which is conducive to the mud collecting barrel (101) and the bottom of the road bridge pile foundation hole. When the mud collecting barrel (101) falls in the road bridge pile foundation hole, the two circular guide shafts (601) and the two conical insertion heads (603) can be inserted into the bottom of the road bridge pile foundation hole under the action of their own weight and the weight of the sealing baffle (602); the motor (202) is turned off, and the two electric cylinders (301) and the two mud suction pumps (401) are started, and the mud in the road bridge pile foundation hole is cleaned up. When the output shafts of the two electric cylinders (301) are extended, the two mud suction pipes (403) pass through the two mud inlet holes (1021), so that the two mud suction pipes (403) move to the bottom of the road bridge pile foundation hole, and at the same time, the two mud inlet holes (1021) are sealed. Function: When the two mud suction pumps (401) are working, the mud at the bottom of the road bridge pile foundation hole enters the two mud suction pumps (401) through the two mud suction pipes (403), and then is discharged through the two mud discharge pipes (404). When the driving frame (302) drives the two driving inclined plates (303) and the two limiting vertical plates (304) to move downward, the two driving inclined plates (303) can squeeze the two limiting plug rods (501), so that the two limiting plug rods (501) are inserted into the side wall of the road bridge pile foundation hole; the output shafts of the two electric cylinders (301) are retracted by half, and the two limiting plug rods (501) can be automatically reset under the action of the two reset springs (502). At the same time, the two mud suction pumps (401) are retracted by half. The pipeline (403) is not separated from the two mud inlet holes (1021); the mud collecting barrel (101) is then taken out from the road bridge pile foundation hole by a crane; the mud collecting barrel (101) is moved to the mud discharge area by the crane, and the mud in the mud collecting barrel (101) is waited to be completely discharged through the four mud discharge holes (1011). When the mud collecting barrel (101) is taken out, the two conical insertion heads (603) are in contact with the ground, and the ground supports the two conical insertion heads (603), so that the sealing baffle (602) can be automatically opened when the mud collecting barrel (101) moves downward; the driving frame (302) is moved to the initial position by two electric cylinders (301).
