As shown in fig. 1 and 2, after the 220V ac power enters the power input terminal of the regulated power supply a1, the regulated power supply a1 outputs a stable 24V dc power to the power input terminals of the second power switch S6, the third power switch S7, the fourth power switch S1, the fifth power switch S2, and the sixth power switch S3, and the power input terminals of the control mechanism are connected to the pins 1 and 2, so that the power switches and the control mechanism are in the power-on operating state. Before the invention is used, inspection personnel inspect and accept the foundation piles (such as various bridge foundation piles) of the built engineering structure, when the safety of engineering buildings on the foundation piles is affected by excessive thickness of clay and sediment at the pile bottom through drilling and sampling equipment during inspection and acceptance, a geological drilling machine is firstly adopted to drill holes (cylindrical pits with certain depth) obliquely around the pile bodies of the foundation piles, and then the barrel bodies 3 (the lower parts of the barrel bodies 3 are positioned at the bottoms in the holes) are placed in the drilled holes. After the barrel 3 is placed into the hole, a worker shifts the shifting handle of the power switch S1 to the right, so that the 1 and 2 feet and the 5 and 6 feet of the power switch S1 are respectively communicated, a 24V power supply can enter the power input ends of the negative and positive poles of the electric telescopic rods MN of the six sets of electric supporting mechanisms, so that the piston rods of the electric telescopic rods MN of the six sets of electric supporting mechanisms can move forwards and outwards and drive the movable rods 62 to move forwards, the movable rods 62 of the six sets of electric supporting mechanisms are tightly contacted with the two sides of the inner side wall of the hole, the barrel 3 can be firmly fixed in the hole, and subsequent operations are ensured (the barrel 3 is prevented from being displaced during the work of a subsequent electric grinder M3 and the. After the barrel is fixed, a worker turns off the power switch S1 and turns on the power switch S6, then the electromagnetic valve DC1 is electrified to work, the inner valve core of the electromagnetic valve DC1 is opened, then the power switch S5 is turned on, then the water pump M5 is electrified to work, external water is pumped into the barrel 3, and sediment, clay and the like in the pot hole in the lower portion of the barrel are washed and cleaned. The high-pressure water pumped into the cylinder 3 by the water pump M5 impacts the sediment and clay in the hole and then flows out of the cylinder through the two fixed pipes 81, and meanwhile, the sediment and clay are taken out of the hole by the water flow. When water flow impacts sediments and clay in the hole, a worker turns on power switches K2 and S4, so that the time control switch A2 is in an electric working state (meanwhile, the electric grinder M3 is in the electric working state to grind the sediments, the clay and the like in the hole); after the time control switch A2 is powered on to work, under the action of an internal circuit of the time control switch A2 and the time of A3-pin output power supply and a 4-pin output power supply set by a technician, a 2-second power supply can be output every 5 seconds, then, a 24V power supply output by the 3-pin output and the 4-pin output of the time control switch A2 can enter the negative and positive pole power supply input end of the electric push rod M2, and the electric push rod M2 is powered on to work, a piston rod of the electric push rod M2 drives the electric crusher M3 to descend for a certain height every 5 seconds, and the. Due to the crushing function of the electric crusher M3, sediment, clay and the like in the holes are more favorably impacted by water flow and then discharged out of the barrel 3.

As shown in fig. 1 and 2, in actual conditions, a worker normally turns off the electric pulverizer M3 after working for 3 minutes according to field conditions (and turns off the power supply of the electric push rod M2, and the piston rod of the electric push rod M2 drives the electric pulverizer M3 to drop to about 10 cm in height, which can fully meet the requirement), and crushing operation is performed within 3 minutes, so that sediments, clay and the like at the lower end in a hole can be effectively removed (power switches S4 and K2 can also be turned off in advance). After a period of time, when the sediments, clay and the like in the holes are cleaned (the water discharged through the fixed pipe 81 is not turbid any more), the working personnel close power switches S6, S5, S4 and K2 (the electromagnetic valve DC1 is power-off and does not work, the water pump M5 is power-off and does not work, the electric grinder M3 is power-off and does not work, the electric push rod M2 is power-off and does not work), then the handle of the power switch S2 is moved to the right, so that the 1 and 2 pins and the 5 and 6 pins of the power switch S2 are respectively communicated, thus, 24V power will enter the negative and positive pole power input ends of the electric push rod M1, the electric push rod M1 is powered on to work, the piston rod thereof drives the second fixed pipe 81 to move downwards (the two fixed pipes 81 are connected by the hose 82 with a length margin, so the second fixed pipe 81 can move downwards), therefore, the lower end of the second fixing pipe 81 can be in contact with the lower end in the hole, and the compressed air output by the subsequent air compressor can be discharged to the outside of the cylinder 3. In practical terms, when the second fixed pipe 81 descends to a certain height, the switch device 83 descends synchronously to a certain height, and after the movable plate 833 contacts the lower end in the hole, as the second fixed pipe 81 continues to descend, the inner contact of the button of the microswitch K1 is disconnected due to the movement of the movable plate 833 being blocked. Because the power switch K1 is connected in series between the 5-pin of the power switch S2 and the positive power input end of the electric push rod M1, the electric push rod M1 loses power and stops working after the movable plate 833 contacts the ground, and the electric push rod M1 is prevented from working all the time to push the switch device and the second fixed tube 81 to move downwards, which causes damages to the switch device and the second fixed tube 81. The second fixed pipe 81 descends to the right, and after one minute, the worker turns on the power switch S7, so that the electromagnetic valve DC2 is powered on to work, the inner valve core is opened, compressed air output by the air compressor enters the barrel 3 through the pipeline, flows out through the second fixed pipe 81, the rubber pipe 82 and the first fixed pipe 81, and meanwhile, the flowing air brings residual water at the lower end in the barrel out of the barrel 3, and the requirement of subsequent concrete pouring is guaranteed. After the residual water is discharged, the worker pulls the toggle handle of the power switch S1 leftwards, so that the 1 and 2 feet and the 3 and 4 feet of the power switch S1 are respectively communicated, thus, a 24V power can enter the power input ends of the positive and negative poles of the electric telescopic rods MN of the six sets of electric supporting mechanisms, then the electric telescopic rods MN of the six sets of electric supporting mechanisms are electrified to work, and the piston rods of the electric telescopic rods drive the movable rods 62 to move inwards and pull the distance between the two side walls in the hole (the power switch S1 is closed after the distance is pulled), so that the worker can lift the barrel out of the hoisting tool used in the hole through the hoisting ring 32. After the barrel 3 is taken out of the hole, a worker injects cement slurry into the hole opening and presses the cement slurry in the hole opening, and after the cement slurry is solidified at the bottom of the pile and in the hole, the foundation pile is better stabilized, so that the construction on the foundation pile is safer to use. In order to facilitate the next use, after the barrel 3 is taken out of the hole, a worker shifts the shifting handle of the power switch S3, so that a 24V power supply enters the positive and negative pole power input ends of the electric push rod M2, the electric push rod M2 drives the electric crusher M3 to ascend to the height and return to the initial position, and then the power switch S3 is turned off; meanwhile, the worker shifts the handle of the power switch S2 to the left, so that a 24V power supply enters the positive and negative pole power input ends of the electric push rod M1 through the 1, 2 and 3, 4 pins of the power switch S1, the electric push rod M1 is electrified to work to drive the second fixing tube 81 to move upwards to an initial position, and then the power switch S2 is turned off.
