It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0020] Embodiment: a bored pile dredging equipment, as shown in Figures 1-4 The trolley 1 is welded and fixed with four support columns 2 at intervals, the sliding plate 21 is slidably connected between the four support columns 2, the rotating shaft 22 is rotatably connected in the middle of the sliding plate 21, the servo motor 23 is bolted and installed on the top middle of the sliding plate 21, the output shaft end of the servo motor 23 is fixedly connected with the upper end of the rotating shaft 22, the mounting plate 3 is welded and fixed on the trolley 1, the screw rod 31 is rotatably connected between the upper part of the mounting plate 3 and the trolley 1, the speed reducer 32 is bolted and installed on the top of the mounting plate 3, the output shaft end of the speed reducer 32 is fixedly connected with the upper end of the screw rod 31, the water pump 4 is bolted and installed on the trolley 1, the water suction pipe 41 is connected with the top of the water pump 4, the drain pipe 42 is connected with the front side of the water pump 4, the water suction pipe 41, the water pump 4 and the drain pipe 42 are communicated in sequence, the rotating shaft 22 is provided with a scraping assembly at the lower end for scraping the sludge, a circular opening is formed in the left side of the trolley 1, and the rotating shaft 22 and the scraping assembly can pass through the circular opening.

[0021] As shown in Figure 1 and Figure 2 The scraping assembly includes the fixed scraper 51, the sliding scraper 52 and the locking screw 53, the fixed scraper 51 is welded and fixed at the lower end of the rotating shaft 22, the sliding scraper 52 is symmetrically and slidably connected on the fixed scraper 51, and the locking screw 53 is symmetrically and threadedly connected on the front and back of the fixed scraper 51. The two locking screws 53 are used for fixing the two sliding scrapers 52 respectively.

[0022] Firstly, the worker pushes the trolley 1 to the cast-in-place pile to be cleaned, ensures that the circular opening formed on the trolley 1 is accurately aligned with the hole of the cast-in-place pile, then loosens the two locking screws 53 to adjust the length of the sliding scraper 52 to adapt to the hole diameter of the current cast-in-place pile, after the adjustment is completed, the two locking screws 53 are tightened to firmly fix the sliding scraper 52, then the worker pours an appropriate amount of water into the cast-in-place pile, starts the speed reducer motor 32, the speed reducer motor 32 drives the lead screw 31 to rotate, and then drives the sliding plate 21 and the fixed scraper 51 and the sliding scraper 52 to move downward as a whole until they reach the bottom of the cast-in-place pile, at this time, the worker starts the servo motor 23, the servo motor 23 drives the rotating shaft 22 to rotate, the rotating shaft 22 drives the fixed scraper 51 and the sliding scraper 52 to agitate the sludge at the bottom of the cast-in-place pile, so that the sludge is mixed with water, then the worker starts the water pump 4, the water pump 4 draws the sludge mixed water (mud water) out through the water suction pipe 41, and finally discharges it through the drain pipe 42, thereby completing the cleaning work of the bottom of the cast-in-place pile. After cleaning the current cast-in-place pile, the worker first closes the servo motor 23 and the water pump 4, and then starts the speed reducer motor 32 again to reverse it, the reverse rotation of the speed reducer motor 32 drives the lead screw 31 to rotate in the opposite direction, thereby moving the sliding plate 21, the fixed scraper 51 and the sliding scraper 52 upward as a whole and returning to the initial position. At this time, the worker only needs to push the trolley 1 to the next cast-in-place pile to be cleaned and repeat the above steps, which not only improves the cleaning efficiency but also greatly reduces the labor intensity of the worker, making the cleaning work more time-saving and labor-saving.

[0023] As shown in Figure 1 , Figure 3 and Figure 4 , it further comprises a mounting frame 61, a filter frame 62 and a filter screen 63, the mounting frame 61 is welded and fixed on the trolley 1, the filter frame 62 is slidably arranged in the mounting frame 61, the filter frame 62 can be lifted upward from the mounting frame 61, one end of the drain pipe 42 is connected with the water pump 4, and the other end is clamped and fixed on the top of the mounting frame 61, so that the mud water flowing out of the drain pipe 42 can fall into the filter frame 62, and the filter screen 63 is arranged at the front side of the filter frame 62.

[0024] By arranging the mounting frame 61 and the filter frame 62, the mud water flowing out of the drain pipe 42 flows into the filter frame 62, the mud water flows out through the filter screen 63, and the sand mixed in the mud water is intercepted, so that the sand can be reused, improving the resource utilization efficiency.

[0025] As shown in Figure 2 , it further comprises an alloy head 7, the alloy head 7 is welded and fixed at the lower end of the rotating shaft 22.

[0026] Through setting the alloy head 7, the strength of the lower end of the rotating shaft 22 is enhanced, so that the rotating shaft 22 is not easily damaged in the collision and friction with the bottom of the cast-in-place pile, and the service life of the rotating shaft 22 is prolonged.

[0027] As shown in Figure 1 , the rubber balls 8 are further arranged on the top of the four supporting columns 2.

[0028] The edges of the top of the supporting columns 2 are wrapped by the rubber balls 8, so that the staff can not directly contact the edges of the top of the supporting columns 2 in the operation process, and the occurrence of accidental injuries such as scratches and collisions is prevented.

[0029] As shown in Figure 1 and Figure 3 , the hooks 9 are further arranged on the middle of the mounting plates 3.

[0030] The water collecting pipes are stored by the hooks 9, so that the water collecting pipes are prevented from being scattered at will, and the staff can quickly take and place the water collecting pipes 41 when needed, the work efficiency and the operation convenience are improved.

[0031] The above is only a specific implementation manner of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
