[0002] Cast-in-place piles are a widely used foundation method in engineering construction. They are constructed by first drilling a hole at the construction site, then placing a steel reinforcement frame inside the hole, and finally pouring concrete. Bored cast-in-place piles are constructed by drilling a hole with a drilling machine, followed by pouring concrete. They are suitable for various geological conditions. The hole diameter and depth are large, and after drilling, the pile needs to be buried underground. During installation, bored cast-in-place piles require a stopper to prevent displacement. Current stoppers for bored piles are inconvenient for piles of varying diameters, necessitating a new stopper for bored piles.
[0003] The existing limiting structure for bored pile drilling is inconvenient to limit bored piles of different diameters during use, resulting in limited application range of the limiting device, and it is inconvenient to guide the bored bored piles to slide down, affecting the smoothness of the bored pile burial, and it is inconvenient to provide stable support for the limiting device. Therefore, a limiting structure for bored pile drilling is urgently needed. Utility Model Content

The first limiting plate 1 and the second limiting plate 3 are both open-hole designs, and the first limiting plate 1 and the second limiting plate 3 are both semi-arc-shaped. The bolt 2 is movably connected to the first limiting plate 1, and the bolt 2 is threadedly connected to the first nut 4, the bolt 2 is movably connected to the second limiting plate 3, and the bolt 2 is threadedly connected to the second nut 5, which can facilitate the limiting of bored piles of different diameters.
[0026] See also Figure 1-4 A limiting structure for bored pile drilling, the inner wall of the first limiting plate 1 is fixedly connected with a support rod 6, one end of the support rod 6 is fixedly connected with a frame plate 7, a pulley 8 is installed inside the frame plate 7, the support rod 6 is arranged in a ring shape with the central axis of the first limiting plate 1 as the center, and the frame plate 7 forms a rotating structure with the pulley 8 through the rotating shaft, which can facilitate the guided sliding of the bored pile.
[0027] See also Figure 1-4 A limiting structure for bored pile drilling, the outer wall of the first limiting plate 1 is fixedly connected to a support plate 9, a limiting nail 10 is installed inside the support plate 9, the support plate 9 is an open-hole design, and the support plate 9 and the limiting nail 10 form a sliding structure, the first limiting plate 1 and the support plate 9 are vertically distributed, and the limiting nail 10 is a slotted design, which can facilitate stable support of the first limiting plate 1.
[0028] Working principle: When in use, place the first limit plate 1 and the bolt 2 on both sides of the drill hole, pass the bolt 2 through the first limit plate 1 and the second limit plate 3 respectively, connect the first nut 4 to one end of the bolt 2 and rotate it. Since the bolt 2 is threadedly connected to the first nut 4, the first limit plate 1 and the second limit plate 3 can be tightened inward, and then the second nut 5 is installed on one end of the bolt 2 in the same way to prevent the first limit plate 1 and the second limit plate 3 from loosening. Due to the difference in diameter of different cast-in-place piles, it is only necessary to adjust and rotate the first nut 4 and the second nut 5 so that The pulleys 8 at different positions always have a contact surface with the outer wall of the bored pile, so that the bored pile is limited.
