[0040] Please see attached Figure 3 - Attachment Figure 4 , a servo motor 22 is fixedly connected to the rear end of the inner side of the U-shaped plate 4, and a pulley 23 is fixedly connected to the output end of the servo motor 22. The two pulleys 23 are connected by a transmission belt 21. A rotating column 20 is fixedly connected inside the lower pulley 23. One end of the rotating column 20 is rotatably connected to the middle part of the rear side of the right U-shaped plate 4. The upper pulley 23 and the end of the rotating column 20 away from the U-shaped plate 4 are both fixedly connected to a rotating roller 2. A square groove 8 is opened on the left side of the top of the frame 1. A support plate 9 is fixedly connected inside the square groove 8. A baffle 7 is fixedly connected to the left side of the inside of the square groove 8. An I-shaped column 15 is rotatably connected to the middle part of the top of the support plate 9. The long rope 6 is located between the two I-shaped columns 15. Bolts 13 are pierced on the top of the I-shaped columns 15. The bottom end of the bolt 13 is threadedly connected to the top surface of the support plate 9, and the inner side of the I-shaped column 15 is slidably connected to the outer wall of the long rope 6.

[0041] Specifically, the pulley 23 is driven by the servo motor 22, and then the transmission belt 21 is driven by the pulley 23, so that the other pulley 23 is driven, and the rotating column 20 and the rotating roller 2 are driven at the same time.

[0042] Working principle: The ultrasonic probe 12 is controlled to descend at a uniform speed from the hole mouth 19, and the depth measuring device 14 measures the depth of the ultrasonic probe 12 and transmits it to the host 11. The host 11 controls the ultrasonic transmitter 12 to transmit ultrasonic waves according to the set time interval and synchronously starts the timer 17. The host 11 starts the high-speed and high-precision signal collector 16 to collect ultrasonic signals according to the set sampling delay and sampling rate. Since the acoustic impedance of the mud is much smaller than the acoustic impedance of the soil medium, the ultrasonic wave is almost totally reflected by the hole wall. The reflected wave is received by the receiving transducer 10 after propagating through the mud. The time when the reflected wave arrives is the propagation time of the ultrasonic wave in the mud in the hole. The distance between the ultrasonic transducer and the hole wall is calculated by the propagation time, thereby calculating the aperture value and verticality of the section, and the ultrasonic velocity is calibrated through the hole mouth 19.
