[0021] Please see Figures 1-5 This embodiment provides a pile hole measuring device, including a fixed plate 1. Telescopic mechanisms 2 are installed at both ends of the fixed plate 1. A rod 9 is installed at the outer end of the telescopic mechanism 2. The telescopic mechanism 2 includes a hollow rod 3 and a moving block 5. A groove 4 is formed at the upper end of the hollow rod 3. The moving block 5 is slidably connected inside the hollow rod 3. A crossbar 8 is installed at the outer end of the moving block 5, and the crossbar 8 passes through the hollow rod 3 to fix the rod 9. A rotating bolt 6 is rotatably connected to the upper end of the moving block 5, and the rotating bolt 6 passes through the groove 4. A pressing block 7 is threadedly connected to the outer surface of the rotating bolt 6. Rubber anti-slip blocks are symmetrically installed at the lower end of the pressing block 7. A rotating shaft 10 is rotatably connected to the upper end of the fixed plate 1. Several threaded grooves 11 are formed at the upper end of the fixed plate 1, and these threaded grooves 11 are arranged in a circle on the upper end of the fixed plate 1. A connecting block 12 is installed on the outer surface of the rotating shaft 10. A fastening bolt 13 is provided inside the connecting block 12, and the fastening bolt 13 corresponds to the threaded groove 1. At position 1, a pushing mechanism 14 is installed on the upper end of the rotating shaft 10. The pushing mechanism 14 includes a hollow plate 15 and a threaded rod 16. The threaded rod 16 is rotatably connected inside the hollow plate 15. A threaded sleeve 17 is fitted on the outer surface of the threaded rod 16. Extending rods 18 are symmetrically installed on the side of the threaded sleeve 17. The two extending rods 18 pass through the hollow plate 15 and are fixedly connected to the measuring mechanism 20. A shoulder strap 19 is installed on the upper end of the hollow plate 15. The measuring mechanism 20 is installed on the side of the pushing mechanism 14. The measuring mechanism 20 includes a mating block 21 and a hexagonal measuring block 27. A through hole 22 is opened inside the mating block 21. Rollers 23 are symmetrically arranged inside the through hole 22. A take-up and release wheel 24 is set on the upper end of the mating block 21. A stepper motor 25 is installed on the left end of the take-up and release wheel 24.

Six sets of underwater acoustic sensors 28 are installed on the side of the hexagonal measuring block 27.

[0022] The working principle of this utility model is as follows: Pulling the insertion rod 9 moves the crossbar 8 and the moving block 5. Then, rotating the rotating bolt 6 causes the pressing block 7 to descend and press against the hollow rod 3, fixing the position of the insertion rod 9. Next, the two insertion rods 9 are inserted into the soil, fixing the position of the fixing plate 1. Then, the rotating shaft 10 drives the pushing mechanism 14 and the measuring mechanism 20 to rotate, causing the measuring mechanism 20 to rotate above the pile hole. Then, rotating the threaded rod 16 moves the threaded sleeve 17, which in turn moves the measuring mechanism through the extending rod 18. The measuring mechanism 20 is moved to the center of the pile hole. Then, the stepper motor 25 controls the take-up and release wheel 24 to rotate. The take-up and release wheel 24 rotates to wind up or lengthen the measuring rope 26, causing the hexagonal measuring block 27 to descend or rise in the pile hole. The distance from the sensor to the hole wall is calculated by emitting sound waves to the hole wall and receiving the reflected signals through the underwater acoustic sensor 28. At the same time, by precisely controlling the number of steps of the stepper motor 25, the hexagonal measuring block 27 can be continuously descended or risen in the hole, thereby obtaining cross-sectional data at different depths.
