Before the pile is constructed, the hole diameter, verticality, hole depth, etc. need to be tested to determine whether the hole quality meets the relevant technical standards and design requirements.
[0003] The existing pile hole diameter detection device can adjust the relative position of the measuring rod and the inner wall of the pile hole, so as to perform multiple measurements on different positions of the inner wall of the pile hole. For example, Chinese patent application No. CN202121513279.5 discloses a pile hole diameter detection device for construction project supervision, including a circular ring base, in which a measuring disk is rotatably connected, and a plurality of circumferentially symmetrical rectangular slide grooves are provided in the measuring disk, and a rectangular slider is slidably connected in the rectangular slide groove, and the lower ends of the plurality of rectangular sliders are fixedly connected to a vertically arranged measuring rod through a connecting piece arranged through the measuring disk.

Two slide grooves 10 corresponding to the arc groove 9 are provided, and columns 11 are slidably connected inside the two slide grooves 10. The two columns 11 are connected to a cylinder 13 on the side away from each other through a fixed rod 12. A laser rangefinder 14 is installed on the side of the fixed rod 12 close to the cylinder 13. A spring 15 is connected inside the cylinder 13. The end of the spring 15 away from the fixed rod 12 is connected to an inner cylinder 16. The side of the inner cylinder 16 away from the spring 15 is connected to a plate 17. A plurality of support rods 18 are connected to the upper side of the outer surface of the shell 1. The end of the support rod 18 away from the shell 1 is bent downward. The laser rangefinder 14 faces the corresponding plate 17. An Internet of Things controller is installed inside the shell 4, and the laser rangefinder 14 is connected to the Internet of Things controller through a line.
[0026] During operation, the support rod 18 is supported on the ground, and the housing 4 is placed in the pile hole. The motor 5 drives the disc 7 to rotate, and the inner wall of the arc groove 9 pushes the column 11 to slide in the slide groove 10, so that the two columns 11 are separated from each other. The column 11 pushes the fixed rod 12, the cylinder 13, the inner cylinder 16, and the plate 17 to move toward the inner wall of the pile hole.

The data detected by the laser rangefinder 14 is wirelessly transmitted to the external device through the Internet of Things controller. In the detected data, when the sum of the distances detected by the two laser rangefinders 14 at the same moment is the largest, the sum of the two distances plus the distance between the two laser rangefinders 14 is the pile hole diameter.

A motor control receiver is installed inside the motor 5 and the hollow shaft motor 6, and the pressure sensor 19 is connected to the motor control receiver through a line.
[0028] During operation, after the abutment plate 17 approaches the inner wall of the pile hole and fits therewith, the pressure sensor 19 receives the pressure signal and transmits the signal to the motor control receiver through the line, thereby controlling the motor 5 to stop, and then controlling the hollow shaft motor 6 to drive the housing 4 to rotate. There is no need to observe with the naked eye whether the abutment plate 17 fits the inner wall of the pile hole, and it is easy to use.
[0029] See also Figure 1-5 The utility model provides a technical solution: the end of the support rod 18 away from the housing 1 is tapered.
[0030] During operation, by setting one end of the support rod 18 to be tapered, the one end of the support rod 18 can be inserted into the ground, thereby improving the stability of the support rod 18 after being fixed.
[0031] See also Figure 1-5 The utility model provides a technical solution: openings are symmetrically opened on the upper surface of the shell 1, and a filter screen 20 is connected inside the opening.

[0035] See also Figure 1-5 The utility model provides a technical solution: the outer surface of one end of the support rod 18 away from the housing 1 is connected with a pressing plate 22 .
[0036] During operation, through the setting of the pressing plate 22 , after the support rod 18 is inserted into the ground, the pressing plate 22 fits against the ground, so that the contact area between the support rod 18 and the ground is increased, thereby improving the stability of the support rod 18 .
[0037] See also Figure 1-5 The utility model provides a technical solution: both sides of the outer surface of the abutment plate 17 are arc surfaces 23.
[0038] During operation, the arc surface 23 is arranged so that the abutment plate 17 is not easily blocked by protruding soil when it moves along the inner wall of the pile hole.
[0039] In summary, insert one end of the support rod 18 into the ground, and put the shell 4 into the pile hole. The motor 5 drives the disc 7 to rotate, and the inner wall of the arc groove 9 pushes the column 11 to slide in the slide groove 10, so that the two columns 11 are separated from each other.

The setting of the one-way bearing 8 can prevent the motor 5 from rotating with the shell 4. The shell 4 drives the plate 17 to rotate, and the plate 17 slides along the inner wall of the pile hole. At the same time, the laser distance measurement The instrument 14 continuously detects the distance between the plate 17 and the laser rangefinder 14 itself. When the plate 17 contacts the raised or recessed part of the inner wall of the pile hole, the spring 15 will shrink or push the plate 17 accordingly. At the same time, the distance between the plate 17 and the laser rangefinder 14 will change and be detected by the laser rangefinder 14. After the hollow shaft motor 6 drives the plates 17 on both sides to rotate 180 degrees, the detection is completed. The hollow shaft motor 6 drives the plates 17 back to the initial position. The data detected by the laser rangefinder 14 is wirelessly transmitted to the external device through the Internet of Things controller. In the detected data, when the sum of the distances detected by the two laser rangefinders 14 at the same moment is the largest, the sum of the two distances plus the distance between the two laser rangefinders 14 is the pile hole diameter.
