A plurality of chutes 13 are opened on the outside of the ground nail 4. The quantity and position distribution of the chutes 13 are reasonable, which can provide a track for the sliding of the slider 11;

[0037] A drilling component for insertion is fixedly connected to the bottom of the ground nail 4. The drilling component includes a conical block 14, which facilitates the installation of the ground nail 4. The top of the conical block 14 is fixedly connected to the bottom of the ground nail 4.

A plurality of card slots 23 are provided on the outside of the ground nail 4.

[0040] Working principle: When installing the foundation plate 1, first rotate and insert the ground nail 4 into the ground. Then, during the rotation of the ground nail 4, soil enters the inside of the ground nail 4 through the entry slots 15, making the inside of the ground nail 4 heavier. Then, the spiral blades 16 increase the reinforcement area between the ground nail 4 and the underground. Then, the conical block 14 quickly inserts into the ground. When the foundation plate 1 slides outside the ground nail 4, the bottom of the foundation plate 1 squeezes the slider 11. After the slider 11 slides inside the ground nail 4 in cooperation with the cylinder sleeve 10 and the spring 9, the triangular support block 12 supports the bottom of the foundation plate 1. At the same time, the foundation plate 1 no longer squeezes the slider 11. The slider 11 is pushed by the spring 9 and pops out to limit the top of the foundation plate 1. Then, the plurality of foundation plates 1 are installed and connected through the fixing slots 2 and bolts 3;

[0041] After installation, after the mounting block 17 is installed at a suitable position on the top of the foundation plate 1 in cooperation with the inner threaded cylinder 18, by rotating the outer threaded cylinder 19, the outer threaded cylinder 19 rotates inside the inner threaded cylinder 18 and the inner threaded cylinder 20, so that the outer threaded cylinder 19 drives the inner threaded cylinder 18 and the inner threaded cylinder 20 to move in opposite directions when rotating, so that the inner threaded cylinder 20 cooperates with the mounting block 22 and is pushed into the inside of the card slot 23, so that the foundation plate 1 and the ground nail 4 are additionally installed and fixed through the mounting block 22 and the card slot 23, and then the traction wire 21 plays a traction role between the mounting block 17 and the mounting block 22.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
