[0020] Please see Figure 1 One end of the bolt 12 penetrates into the inner cavity of the sliding plate 9 and contacts the bracket 8. The bolt 12 is threaded to the inner wall of the sliding plate 9. By setting the bolt 12, two objects are connected and fixed, and mechanical strength and stability are provided by the preload.

[0021] Please see Figure 1 and Figure 3 A fixed plate 14 and a support plate 15 are welded to the top of the lifting plate 5. An adjusting rod 16 is provided through the surface of the fixed plate 14. A pull plate 17 is welded to one end of the adjusting rod 16. A return spring 18 is fixedly connected between the pull plate 17 and the fixed plate 14. A connecting rod 19 is movably connected to the surface of the adjusting rod 16 through a rotating shaft. A limit plate 20 is movably connected to the surface of the connecting rod 19 through a rotating shaft. By setting the fixed plate 14, the load-bearing capacity and stability of the structure are enhanced, and the overall durability is improved.

[0022] Please see Figure 3 A guide rod 21 is welded to one side of the support plate 15. The limiting plate 20 is movably sleeved on the surface of the guide rod 21. By setting the guide rod 21, stable and precise guidance and support are provided to ensure that the moving parts can move smoothly and accurately along the predetermined trajectory.

[0023] Please see Figure 3The return spring 18 is movably sleeved on the surface of the adjusting rod 16, and the adjusting rod 16 is in movable contact with the inner wall of the fixed plate 14. By setting the adjusting rod 16, the supporting, fixing and connecting functions are provided, and the connection between different components is realized.

[0024] Please see Figure 1 An electric telescopic rod 22 is fixedly installed between the base plate 1 and the lifting plate 5. A groove 23 is provided on the inner wall of the bracket 2. A slider 24 is welded to the surface of the lifting plate 5. The slider 24 extends into the inner cavity of the groove 23 and is movably connected to the inner wall of the groove 23. By setting the groove 23, a convenient support point is provided, which facilitates the operation, movement or control of the lifting plate 5.

[0025] In use, first move the device to the construction position, push the sliding plate 9 to slide on the surface of the bracket 8, press the fixing column 10 to tilt and unfold so that one side of the support plate 11 is away from the base plate 1, extending the distance between the support plate 11 and the base plate 1. Use the end of the bolt 12 to abut against the bracket 8, so that the sliding plate 9 fits against the bracket 8 for support. Insert the fixing nail 13 into the ground to position and lock the support plate 11, making the bracket 2 more stable. Start the electric telescopic rod 22 to extend and lift the lifting plate 5 vertically. The vertical sliding causes the slider 24, which is fixed to it, to slide and guide in the inner cavity of the slide groove 23, which can be adjusted according to the installation depth of the external anchor rod. The support height is adjusted by pushing the pull plate 17 to one side, which compresses the return spring 18 and causes the adjusting rod 16 to move laterally. During the movement of the adjusting rod 16, the connecting rod 19 is tilted and adjusted, so that the separation distance between the two sides is extended and the limiting plate 20 is extended. The limiting plate 20 is slid away from each other along the surface of the guide rod 21 under external force. The anchor rod is inserted into the limiting hole 6. The pull plate 17 is released, and the adjusting rod 16 is pushed by the rebound force of the return spring 18 to move the connecting rod 19, so that the limiting plate 20 returns to its original position and is locked onto the surface of the corresponding anchor rod to fix the anchor rod. Finally, the hydraulic rod 3 can be started to carry out the static pressure pile construction of the anchor rod, so that the construction can proceed normally.

[0026] In summary, this stable prestressed anchor static pressure pile construction device, through the cooperation of the base plate 1, support 2, hydraulic rod 3, abutment plate 4, lifting plate 5 and adjustment mechanism 7, solves the problem of not being able to effectively reinforce the foundation, thus increasing the difficulty and cost of construction.
