[0002] Onshore pipe pile plug refers to the soil plug formed when soil flows into the pipe pile during the static pressure pipe pile sinking process. This soil plug effect is a phenomenon in the open hollow pile sinking process, in which soil enters the pipe pile and affects the degree of pile end resistance. The height change of the soil plug reflects the balance between the end resistance of the soil plug, the internal friction resistance between the soil plug and the pipe pile wall, and the shear strength of the soil plug. The height change of the soil plug is the core issue in studying the mechanical mechanism of the soil plug effect. Through field measurements, it is found that the cross-sectional size of the pile is the main factor affecting the height of the soil plug.

[0003] At present, the real-time measurement device for the soil plug height of onshore pipe piles usually needs to be fixed on the pipe piles. However, the fixing structure of the measurement device has certain limitations, and the sizes of the pipe piles vary, making the installation of the measurement device more difficult and affecting the convenience of the device.

A slide groove 3 is provided at the lower end of the device fixing frame 1. A double-threaded rod 4 is provided inside the device fixing frame 1. A connecting shaft 5 is fixedly installed at the right end of the double-threaded rod 4. A rotating handle 6 is fixedly installed at the right end of the connecting shaft 5 extending to the outside of the device fixing frame 1. Moving blocks 7 are provided on both sides of the surface of the double-threaded rod 4. The lower end of the moving block 7 is fixedly installed. There is a connecting piece 8, the lower end of the connecting piece 8 extends to the outside of the slide groove 3 and is fixedly installed with a clamping fixing plate 9, the front end of the equipment fixing frame 1 is fixedly installed with a pulley box 10, the left side of the front end of the equipment fixing frame 1 is fixedly installed with a pulley box 2, the upper end of the balance block 2 is fixedly installed with a connecting steel wire 12, the end of the connecting steel wire 12 away from the balance block 2 passes through the pulley box 10 and the pulley box 2 11 and is fixedly installed with an indicator block 13, and the front ends of the pulley box 10 and the pulley box 2 11 are both provided with pulley box covers 14.

[0022] See also Figure 2-Figure 3 The left end of the double-threaded rod 4 is rotatably connected to the equipment fixing frame 1, and the connecting shaft 5 is rotatably connected to the equipment fixing frame 1. The threads on the left and right sides of the double-threaded rod 4 are rotated in opposite directions, and the two moving blocks 7 are respectively threadedly connected to the left and right sides of the surface of the double-threaded rod 4. The moving block 7 is slidably connected to the equipment fixing frame 1, and the connecting piece 8 is slidably connected to the slide groove 3. The clamping fixing plate 9 is designed with an arc structure. A buffer protection pad is fixedly installed on the clamping fixing plate 9. First, the equipment fixing frame 1 is placed on the pipe pile, and the connecting shaft 5 is driven to rotate by rotating the turning handle 6, so that the double-threaded rod 4 drives the moving block 7 to move, thereby driving the two clamping fixing plates 9 to move in the direction of the pipe pile until the buffer protection pad is tightly fitted with the pipe pile, thereby realizing rapid installation and fixing of the measuring device, and utilizing the adjustable clamping fixing mechanism to facilitate adaptation to pipe piles of different sizes, which is beneficial to improving the adaptability range and installation convenience of the onshore pipe pile soil plug height real-time measuring device.

[0023] See also Figure 1 and Figure 4In this embodiment, the two pulley box covers 14 are rotatably connected to the pulley box 10 and the pulley box 2 11 respectively. The pulley box covers 14 are made of transparent acrylic plate. A spirit level 15 is fixedly installed on the rear side of the upper end of the equipment fixing frame 1. A handle 16 is fixedly installed on the front end of the pulley box cover 14. The pulley box cover 14 is made of transparent acrylic plate, which makes it convenient for staff to observe the working status of the pulley and the connecting wire 12. When a component is stuck, the fault location and cause can be quickly discovered, and repair and adjustment can be carried out to avoid affecting the normal operation of the measuring device, which is conducive to improving the practicality of the onshore pipe pile soil plug height real-time measurement device.

[0024] When working, first place the equipment fixing frame 1 on the pipe pile, and drive the connecting shaft 5 to rotate by turning the handle 6, so that the double-headed threaded rod 4 drives the moving block 7 to move, thereby driving the two clamping fixing plates 9 to move in the direction of the pipe pile until the buffer protection pad is tightly fitted with the pipe pile, thereby realizing the rapid installation and fixing of the measuring device, and the use of an adjustable clamping fixing mechanism is convenient for adapting to pipe piles of different sizes. After the equipment is assembled, since the weight of the balancing block 2 is greater than the weight of the indicator block 13, the balancing block 2 is against the surface of the soil plug inside the pipe pile. In this way, the change in the height of the soil plug inside the pipe pile during the pile sinking process is converted into the displacement of the indicator block 13 outside the pipe pile, so that the soil plug height value can be obtained at any time. The pulley box cover 14 is made of a transparent acrylic plate, which is convenient for staff to observe the working status of the pulley and the connecting steel wire 12. When a component is stuck, the fault location and cause can be quickly discovered, and repaired and adjusted to avoid affecting the normal operation of the measuring device.

[0025] Through the above steps, the rotating handle 6 drives the double-headed threaded rod 4 to rotate, so that the moving block 7 drives the clamping and fixing plate 9 to move toward the pipe pile until the buffer protection pad is tightly fitted with the pipe pile, thereby realizing the rapid installation and fixing of the measuring device. The adjustable clamping and fixing mechanism is used to facilitate adaptation to pipe piles of different sizes to solve the problem that the fixing structure of the measuring device has certain limitations and the sizes of the pipe piles are different, making the installation of the measuring device more difficult.
