DETAILED DESCRIPTION

[0029] In order to better understand the purpose, structure and function of the utility model, the deep hole cast-in-place pile reinforcement cage correction adjusting device provided by the utility model is further described in detail below in combination with the drawings, so that those skilled in the art can better understand and implement the utility model, but the embodiments are not as a limitation on the utility model.

[0030] Embodiment one

[0031] Please refer to Figures 1 to 5As shown, the embodiment provides a deep hole cast-in-place pile reinforcement cage correction adjusting device for preventing deviation, which comprises a casing 100 and a positioning assembly movably connected in the casing 100; the positioning assembly comprises at least three positioning columns 200 movably connected on the inner side wall of the casing 100 around the central axis of the casing 100; the positioning column 200 comprises a hanging piece 210 and a first positioning part 220; one end of the hanging piece 210 is hung on the upper end of the casing 100, and the other end is fixed on the upper end of the first positioning part 220; the inner side wall of the first positioning part 220 is attached to the inner side wall of the casing 100, and the end of the first positioning part 220 away from the hanging piece 210 extends downwardly with a second positioning part 230, the outer side wall of the second positioning part 230 is flush with the outer side wall of the first positioning part 220, the thickness of the first positioning part 220 is greater than the thickness of the second positioning part 230, and the lower end of the second positioning part 230 extends downwardly beyond the lower end of the casing 100.

[0032] Due to the casing 100 and the positioning assembly, and the positioning assembly comprising at least three positioning columns 200, the positioning column 200 comprising a hanging piece 210, a first positioning part 220 and a second positioning part 230, through the cooperation of the above components, the reinforcement cage 500 can be positioned from multiple directions, ensuring that the central axis of the reinforcement cage 500 is always on the same straight line with the central axis of the casing 100 and the pile hole during the process of putting the reinforcement cage 500 into the pile hole, ensuring that the subsequent cast-in-place pile overall structure is uniformly stressed, improving the quality of the deep hole cast-in-place pile, reducing the quality risks such as insufficient bearing capacity of the deep hole cast-in-place pile caused by the deviation of the position of the reinforcement cage 500, and also reducing the time for repeatedly adjusting the position of the reinforcement cage 500 during construction, making the installation process of the reinforcement cage 500 more smooth, thereby shortening the installation time of the reinforcement cage 500 and improving the efficiency of the deep hole cast-in-place pile construction as a whole. At the same time, the deep hole cast-in-place pile reinforcement cage 500 correction adjusting device can also be more flexible in operation during installation and adjustment, and can be adjusted according to the specific conditions in actual construction, such as casings 100 of different diameters, reinforcement cages 500 of different specifications, etc., to enhance the applicability and versatility of the deep hole cast-in-place pile reinforcement cage 500 correction adjusting device.

[0033] Specifically, the hanging piece 210 is arranged to fix the positioning column 200 inside the casing 100, and at least three positioning columns 200 are arranged on the inner side wall of the casing 100 at equal intervals around the central axis of the casing 100, to constrain the reinforcement cage 500 from multiple directions. When the reinforcement cage 500 is placed into the casing 100, the first positioning part 220 and the second positioning part 230 of the positioning column 200 contact the outer periphery of the reinforcement cage 500, limit the movement of the reinforcement cage 500 in the horizontal direction, and make the central axis of the reinforcement cage 500 always coincide with the central axis of the pile hole, thereby achieving positioning of the reinforcement cage 500. Further, the first positioning part 220 is arranged to abut the inner side wall of the casing 100, to provide stable support for the reinforcement cage 500 and ensure the accuracy of positioning; the second positioning part 230 is arranged such that the outer side wall of the second positioning part 230 is flush with the outer side wall of the first positioning part 220, to play a guiding role during the lowering of the reinforcement cage 500, guide the reinforcement cage 500 to accurately enter the predetermined position, prevent the reinforcement cage 500 from shaking or deviating when entering the deep hole, and further improve the accuracy of construction. In addition, in the embodiment of the present application, the positioning assembly includes six positioning columns 200, which are movably connected to the inner side wall of the casing 100 at equal intervals around the central axis of the casing 100. The arrangement of the six positioning columns 200 can more comprehensively and uniformly limit the movement of the reinforcement cage 500 in the horizontal direction, so that the central axis of the reinforcement cage 500 always coincides with the central axis of the pile hole, greatly reducing the positional deviation of the reinforcement cage 500 such as deviation and inclination.

[0034] In a preferred embodiment, the upper end of the first positioning part 220 is further fixedly connected with a lifting ring 221. Due to the arrangement of the lifting ring 221, the construction personnel can conveniently lift the positioning column 200 through the lifting ring 221 when installing the positioning assembly, accurately place the positioning column 200 into the predetermined position inside the casing 100, make the installation process more efficient, and reduce the labor input and installation difficulty. Moreover, the construction personnel can conveniently lift and remove the positioning column 200 from the casing 100 after the construction is completed or when the positioning column 200 needs to be repaired or replaced.

[0035] In a preferred embodiment, the end of the hanger 210 furthest from the first positioning part 220 is provided with a fastener 211 for fixing the hanger 210 to the upper end of the casing 100. Because of the fastener 211, the hanger 210 can be firmly fixed to the upper end of the casing 100, preventing the positioning column 200 from falling off the casing 100 due to external forces (such as collisions with the reinforcing cage 500) during construction, thus improving the stability of the positioning column 200 and keeping it in an accurate position. This achieves precise positioning of the reinforcing cage 500, reduces offset errors during installation, and improves the construction quality of the cast-in-place pile. Furthermore, when installing the positioning column 200, construction workers can quickly place the hanger 210 on the upper end of the casing 100 and then fix it with the fastener 211, eliminating the need for complex installation steps and greatly improving construction efficiency.

[0036] Example 2

[0037] Please see Figure 6 As shown, this embodiment provides a deep-hole cast-in-place pile reinforcement cage correction and adjustment device for preventing displacement. The difference from Embodiment 1 lies only in that at least one first arc-shaped connector 310 is horizontally connected between any two adjacent first positioning parts 220, and the first arc-shaped connectors 310 located in the same plane intersect with the first positioning parts 220 to form a first circular positioning structure 300. The center of the first circular positioning structure 300 is located on the central axis of the casing 100. Other parts of this embodiment are the same as in Embodiment 1 and will not be described again.

[0038] Because at least one first arc-shaped connector 310 is horizontally connected between any two adjacent first positioning parts 220, and the first arc-shaped connectors 310 located in the same plane intersect and connect with the first positioning parts 220 to form a first circular positioning structure 300, the entire positioning assembly forms a more stable whole. This allows the positioning assembly to better withstand various forces generated during the lowering of the rebar cage 500, such as gravity and impact, reducing the shaking and deformation of the positioning column 200, thereby improving the positioning accuracy. Specifically, in this embodiment, multiple first arc-shaped connectors 310 are horizontally connected between any two adjacent first positioning parts 220. That is, multiple first arc-shaped connectors 310 are evenly spaced longitudinally distributed between two adjacent first positioning parts 220 along the length direction of the first positioning part 220, simultaneously forming multiple first circular positioning structures 300. This helps to improve the overall stability of the positioning assembly and provides more accurate positioning guidance for the rebar cage 500. In addition, the first arc-shaped connector 310 has multiple evenly distributed limiting grooves on the side wall opposite to the inner wall of the casing 100. By setting the limiting grooves, the rotation of the steel cage 500 during the lowering process can be effectively prevented, and the steel cage 500 can be quickly guided to accurately enter the predetermined position, thereby improving construction efficiency.

The other parts of this embodiment are the same as those of the first embodiment, and will not be described again.

[0041] Because at least one second arc-shaped connecting piece 410 is horizontally connected between any two adjacent second positioning parts 230, and the second arc-shaped connecting pieces 410 in the same plane are cross-connected with the second positioning parts 230 to form a second circular ring positioning structure 400, the entire positioning assembly forms a more stable whole, so that the positioning assembly can better withstand various forces generated during the lowering of the reinforcement cage 500, such as gravity, impact force, etc., reduce the shaking and deformation of the positioning column 200, and thus improve the positioning accuracy. Specifically, in the embodiment of the present application, multiple second arc-shaped connecting pieces 410 are horizontally connected between any two adjacent second positioning parts 230, i.e. multiple second arc-shaped connecting pieces 410 are longitudinally distributed between two adjacent first positioning parts 220 along the length direction of the second positioning part 230 at equal intervals, and at the same time form multiple second circular ring positioning structures 400, which is conducive to improving the overall stability of the positioning assembly and providing more accurate positioning and guidance for the reinforcement cage 500. In addition, multiple uniformly distributed limiting grooves are formed on the side wall of the second arc-shaped connecting piece 410 away from the inner side wall of the casing 100, which can effectively prevent the rotation of the reinforcement cage 500 during the lowering process, quickly guide the reinforcement cage 500 to accurately enter the predetermined position, and improve the construction efficiency.
