[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-Figure 3, a device for detecting the verticality of an ultra-deep pile foundation, comprising an outer shell 1, a threaded rod 3 threadedly connected to the outer shell 1 is provided through the top of the outer shell 1, a handle 2 is fixedly installed at one end of the threaded rod 3 outside the outer shell 1, a driving tube 10 is rotatably connected to the inner bottom of the outer shell 1, an outer plate 13 is fixedly installed on the outer wall of the driving tube 10, a driving mechanism is arranged in the outer shell 1, the driving mechanism comprises a driving block 14 fixedly installed on the inner wall of the driving tube 10, one end of the threaded rod 3 located in the outer shell 1 is rotatably connected to a driving column 8, one end of the driving column 8 extends into the driving tube 10, a driving groove 9 is opened on the outer wall of the driving column 8, the driving block 14 is located in the driving groove 9 and is slidably connected to the inner wall of the driving groove 9;

[0020] Four extension mechanisms are arranged in the outer shell 1, and the extension mechanism includes an extension rod 5 arranged below the outer disk 13, the top of the extension rod 5 is rotatably connected with an adjusting column 11, an adjusting slot 12 is provided on the outer disk 13, the adjusting column 11 passes through the adjusting slot 12 and is slidably connected to the inner wall of the adjusting slot 12, a slot 4 is provided on the outer side wall of the outer shell 1, one end of the extension rod 5 extends into the slot 4 and is slidably connected to the inner wall of the slot 4, two symmetrically arranged fixing blocks 7 are fixedly installed on the inner wall of the outer shell 1, a guide rod 6 is fixedly connected between the two fixing blocks 7 and the inner top of the outer shell 1, guide blocks 15 are slidably sleeved on the two guide rods 6, and the two guide blocks 15 are fixedly connected to the driving column 8, the driving slot 9 is spiral, and the adjusting slot 12 is arc-shaped.

[0021] When the utility model is used, the device is first placed inside the pile foundation hole, and then the handle 2 is turned forward to make the threaded rod 3 rotate forward. When the threaded rod 3 rotates forward, the guide rod 6 and the guide block 15 are arranged to make the driving column 8 move downward. When the driving column 8 moves downward, the driving groove 9 and the driving block 14 are arranged to make the driving block 14 slide in the driving groove 9, so that the driving tube 10 (attached Figure 3 State) rotates clockwise, when the driving tube 10 rotates clockwise, by providing the adjusting slot 12 and the adjusting column 11, the adjusting column 11 can slide in the adjusting slot 12, and because the adjusting slot 12 is arc-shaped, the four extension rods 5 can all move in the direction away from the driving tube 10. When one end of the four extension rods 5 fits with the inner wall of the pile foundation hole, the rotation of the handle 2 can be stopped, and then the device is lowered to the bottom of the pile foundation hole by the traction equipment (existing technology). If it does not drop to the bottom of the pile foundation hole, it means that the verticality of the pile foundation hole is unqualified. On the contrary, the verticality of the pile foundation hole is qualified. In this way, the ultra-deep pile foundation can be adjusted in time, and the verticality of the ultra-deep pile foundation can be easily met. Standard.
