[0027] Refer to Figure 1-6, an embodiment provided by the present utility model: a device for bored pile perfusion and pile body quality detection, comprising a housing 1. A motor 3 is fixedly connected to the top end of the housing 1. The driving end of the motor 3 penetrates the inner wall of the housing 1 and is fixedly connected to a gear ring 4. Four parts on the lower side of the outer wall of the gear ring 4 are respectively meshed with gears 5. The middle part of the bottom end of the housing 1 is fixedly connected to an electric push rod 9. The bottom end of the electric push rod 9 is fixedly connected to an installation cylinder 10. A perfusion pipe 16 is fixedly connected to the inner wall of the housing 1. A slider 7 is threadedly connected to the outer wall of a threaded rod 6. The bottom ends of the sliders 7 are respectively fixedly connected to mounting plates 8. The inner ends of the threaded rods 6 are respectively rotatably connected to the outer sides of the inner walls of the housing 1. The outer walls of the sliders 7 are respectively slidably connected to the four sides of the inner wall of the housing 1. A control panel 2 is fixedly connected to the front side of the top end of the housing 1. The control panel 2 is electrically connected to the motor 3 and the electric push rod 9. The control panel 2 is information-connected to an ultrasonic detection head 15.

[0028] Specifically, place the device on the top end of the bored pile, and start the motor 3 through the control panel 2. The motor 3 drives the gear ring 4, the gears 5, and the threaded rods 6 to rotate. The threaded rods 6 drive the sliders 7 to move inward, and at the same time drive the mounting plates 8 to move synchronously. Clamp the bored pile through the mounting plates 8, and fix the detection device on the top end of the bored pile. The detection device can be fixed on the top ends of bored piles with different shapes and diameters, avoiding the situation that it may be impossible to accurately monitor and evaluate the perfusion condition and pile body quality of the bored pile, thus avoiding affecting the accuracy and reliability of the data. When gaps are detected in the bored pile through the ultrasonic detection head 16, workers can add cement through the perfusion pipe 16 and transport it into the bored pile for perfusion.

[0029] A limiting plate 12 is fixedly connected to the bottom end of a spring 11. A clamping groove 13 is opened on the lower side of the inner wall of the installation cylinder 10. A clamping rod 14 is arranged on the inner wall of the clamping groove 13. The outer wall of the limiting plate 12 is slidably connected to the inner wall of the installation cylinder 10.

The top end of the gear ring 4 is rotatably connected to the upper side of the inner wall of the housing 1. The outer ends of the gears 5 are respectively rotatably connected to the inner sides of the inner walls of the housing 1.

[0030] Specifically, when the ultrasonic detection head 15 needs to be replaced, workers only need to push the ultrasonic detection head 15 upward and rotate it by 90 degrees to take out the clamping rod 14 from the installation cylinder 10, and then the ultrasonic detection head 15 can be disassembled. During installation, first insert the clamping rod 14 into the installation cylinder 10 and rotate it to snap the clamping rod 14 into the clamping groove 13, and then drive the limiting plate 12 to move downward through the spring 11 to limit the clamping rod 14, and the installation can be completed. This is convenient for workers to quickly disassemble the ultrasonic detection head 15 from the installation cylinder 10, convenient for replacing the ultrasonic detection head 15, reducing the waiting time of the staff, improving the efficiency of the detection operation, and being beneficial to the progress of the project.

[0031] Working principle: First, place the device on the top of the secant pile, and start the motor 3 through the control panel 2. The motor 3 drives the gear ring 4 to rotate, the gear ring 4 drives the gear 5 on the outer wall to rotate, the gear 5 drives the threaded rod 6 to rotate, the threaded rod 6 drives the slider 7 to move inward, and at the same time drives the mounting plate 8 to move synchronously. Clamp the secant pile through the mounting plate 8 to fix the detection device on the top of the secant pile. Then, start the ultrasonic detection head 15 and the electric push rod 9 through the control panel 2. Detect the secant pile through the ultrasonic detection head 15. At the same time, the electric push rod 9 drives the ultrasonic detection head 15 to move downward by a certain distance for detection, and transmits the detection data to the control panel 2. At the same time, when it is necessary to replace the ultrasonic detection head 15, the worker only needs to push the ultrasonic detection head 15 upward and rotate it by 90 degrees to take out the clamping rod 14 from the mounting cylinder 10, and then the ultrasonic detection head 15 can be disassembled. During installation, first insert the clamping rod 14 into the mounting cylinder 10 and rotate it to snap the clamping rod 14 into the card slot 13. Then, drive the limiting plate 12 to move downward through the spring 11 to limit the clamping rod 14, and the installation can be completed.
