When the spiral vibration rod 19 vibrates in the pile hole, it can effectively stir and mix the slurry, making it more uniform. This helps to ensure the uniform distribution of various components in the slurry and prevents the presence of lumps or uneven mixing in the slurry. The vibration of the vibration rod 19 can break the viscous force in the slurry, making it flow more easily. This is particularly important for the smooth flow of slurry to the bottom or deep part of the pile hole in the grouting operation, helping to improve the smooth progress of construction. The vibration of the vibration rod 19 can destroy the layered structure of the slurry, prevent the solid particles in the slurry from sinking, and maintain the uniformity of the slurry. This is very important for ensuring the continuity and consistency of grouting, helping to improve the quality and reliability of the project. The vibration can make the slurry fully fill the pile hole, improve the consistency and density of the pile body, and make the slurry better penetrate and fill the pile hole, filling the voids and enhancing the structural stability of the pile body. This is very important for improving the bearing capacity and shear strength of the pile body and increasing the safety and reliability of the project. In summary, the spiral vibration rod 19 can improve the uniformity and flowability of the slurry in the pile hole, improve the grouting effect, reduce stratification and sedimentation, and improve the consistency and density of the pile body. These benefits help to improve the grouting quality and enhance the stability and reliability of the project. Through the vibration of the vibration rod 19 inside the vibration insertion rod 14, the contact area between the grouting material and the soil layer can be increased. The vibration can cause the soil particles to undergo slight displacement and rearrangement, allowing the grouting material to better penetrate and fill the pores of the soil layer, thereby improving the grouting effect. The vibration assembly 21 includes a second drive motor, and the output end of the second drive motor is connected with a sector. The sector is located on the upper side of the force plate 20. Through the second drive motor, the sector rotates, and the rotation of the sector can achieve intermittent knocking of the force plate 20. This knocking method can speed up the work. Compared with continuous vibration, intermittent knocking can more effectively transfer energy and improve work efficiency. Through intermittent knocking, energy can be concentrated, and a stronger vibration force can be generated at each knock, thereby better achieving the desired vibration effect. Moreover, by controlling the rotation speed and knocking frequency of the second drive motor, the knocking frequency and force of the sector can be adjusted. In this way, the vibration force and frequency can be adjusted according to specific work requirements to adapt to different construction environments and material properties.

These benefits help to improve the grouting quality and enhance the stability and reliability of the project. Through the vibration of the vibration rod 19 inside the vibration insertion rod 14, the contact area between the grouting material and the soil layer can be increased. The vibration can cause the soil particles to undergo slight displacement and rearrangement, allowing the grouting material to better penetrate and fill the pores of the soil layer, thereby improving the grouting effect. The vibration assembly 21 includes a second drive motor, and the output end of the second drive motor is connected with a sector. The sector is located on the upper side of the force plate 20.

Through intermittent knocking, energy can be concentrated, and a stronger vibration force can be generated at each knock, thereby better achieving the desired vibration effect. Moreover, by controlling the rotation speed and knocking frequency of the second drive motor, the knocking frequency and force of the sector can be adjusted. In this way, the vibration force and frequency can be adjusted according to specific work requirements to adapt to different construction environments and material properties. Figure 7As shown, the inner surface of the vibration rod 14 is provided with a plurality of clamping rings 22 along the axial direction, and the vibration rod 19 penetrates the inside of the clamping ring 22; the spiral vibration rod 19 can increase the friction between the vibration rod 14 and the soil or rock inserted into the ground by contacting the clamping ring 22, thereby improving the vibration effect; the movement of the spiral vibration rod 19 can be more evenly distributed on the surface of the rod, so that the vibration energy is better transmitted to the material inserted into the ground; the spiral vibration rod 19 can increase the contact area between the vibration rod 14 and the underground material by inserting into the inside of the clamping ring 22, increase the friction resistance, thereby improving the vibration effect; this is very important for improving the working efficiency and construction quality of the vibration device; the clamping ring 22 can increase the stability of the vibration rod 14; the spiral vibration rod 19 can tightly connect the vibration rod 14 and the underground material by inserting into the inside of the clamping ring 22, prevent the vibration rod 14 from generating excessive displacement or deviation during vibration, and ensure the stability and safety of construction; in short, the spiral vibration rod 19 penetrating the inside of the clamping ring 22 can improve the vibration effect, increase the friction resistance, improve the loosening and improvement effect of the soil or rock, and improve the stability of the vibration rod 14; these benefits help to improve the working efficiency of the vibration device and ensure the quality and safety of construction.

[0044] Working principle: Before using the bored pile grouting device, first drill a pile hole on the ground using a rotary machine, install a steel pipe cylinder inside the pile hole, then embed a steel reinforcement cage inside the steel pipe cylinder, and then correct the verticality of the steel pipe cylinder and the embedded steel reinforcement cage, then align the pile position with the hole 3 on the installation frame 2, at this time the vibration rod 14 and the vibration rod 19 are located inside the pile hole, then the grouting sleeve 1 penetrates the pile position alignment hole 3.

[0045] When using the bored pile grouting device, first inject grout into the inside of the pile hole using the grouting sleeve 1, and start the power supply of the driving assembly 18, so that the vibration rod 14 moves longitudinally during grouting, and the vibration rod 14 is used to uniformly distribute the grout inside the pile hole to remove air in the grout, and the power supply of the vibration assembly 21 is started, so that the vibration rod 19 vibrates inside the pile hole to further vibrate the grout and avoid air bubbles or faults inside the grout, to ensure the quality of the bored pile.

[0046] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
