[0027] A driving assembly, which includes a driving motor 7 fixedly mounted on the outer wall of the bottom of the support frame 3, a driving gear 8 fixedly sleeved on the output shaft of the driving motor 7, and a transmission gear 9 fixedly sleeved on the drum 4 and meshing with the driving gear 8, and the output shaft of the driving motor 7 passes through the support frame 3;

[0028] The height adjustment assembly includes an adjusting screw 10 threadedly connected to the top of the rotating drum 4, a rotating handle 11 welded to the outer wall of the top end of the adjusting screw 10, and a bearing seat 12 fixedly connected to the outer wall of the top of the lifting rod 5. The bottom end of the adjusting screw 10 is connected to the inner wall of the bearing seat 12 through a bearing;

[0029] Furthermore, a sealing flange 16 is fixedly mounted on the opposite end of the immersed tube 1 and the connecting tube 2, and the two sealing flanges 16 are fixedly connected by bolts, which facilitates the dismantling of the device after use;

[0030] In the specific implementation of this embodiment: after the over-tank is completed, the working height of the scraper plate 6 is adjusted to an appropriate height through the height adjustment component, and then the scraper plate 6 is driven to rotate at a high speed through the driving component, so that after the over-tank construction is completed, the flatness of the pile top area can be ensured by scraping the concrete, avoiding stress concentration caused by the uneven concrete surface, thereby ensuring the overall structural integrity and bearing capacity of the bored pile.

[0031] Example 2, reference Figure 1 and Figure 3 , this embodiment is optimized on the basis of embodiment 1, specifically: a bored pile over-filling leveling device, further comprising an over-filling height detection mechanism provided on the connecting pipe 2;

[0032] In this embodiment, the overfilling height detection mechanism includes a laser distance sensor 13 that penetrates and is fixed to the top of the support frame 3, a mounting plate 14 that is welded to the circumferential outer wall of the connecting pipe 2, and a distance meter 15 that is fixedly mounted on the top outer wall of the mounting plate 14;

[0033] Furthermore, a display screen is provided on the rangefinder 15, and the rangefinder 15 is electrically connected to the laser ranging sensor 13 via a signal line;

[0035] The working principle of the utility model is as follows: first, the connecting pipe 2 to be used is sealed and connected with the immersed pipe 1 in the pile hole through two sealing flanges 16, and then the concrete is poured into the immersed pipe 1 by a pouring machine.

[0037] Finally, after the super-filling construction is completed, the adjusting screw 10 is controlled to rotate by the turning handle 11, and then the adjusting screw 10, which is threadedly connected to the rotating drum 4 and whose bottom end is connected to the bearing seat 12 through a bearing, controls the scraper plate 6 connected to the bottom end of the lifting rod 5 to move downward, and adjusts the working height of the scraper plate 6 to a suitable height;

In this way, by scraping the concrete, the flatness of the pile top area can be ensured, and the stress concentration caused by the uneven concrete surface can be avoided, thereby ensuring the overall structural integrity and bearing capacity of the cast-in-place pile.
