[0019] The supporting mechanism 2 includes a first groove 201, a second groove 202, a first thread groove 203, a first expansion nut 204, a connecting frame 205, a vertical wall 206, a bolt 207, a through hole 208, a second thread groove 209, a second expansion nut 210 and a positioning nail 211. The first grooves 201 are provided on both sides of the supporting plate 1, the second groove 202 is provided on one side of the surface of the supporting plate 1, the first thread groove 203 is provided on one side of the supporting plate 1, and the first expansion nut 204 is fixedly connected to the other side of the supporting plate 1. A connecting frame 205 is embedded in the groove 201, a vertical wall 206 is embedded in the second groove 202, a bolt 207 is threadedly connected to the first thread groove 203, a through hole 208 is opened on one side of the surface of the connecting frame 205, a second thread groove 209 is opened in the vertical wall 206, a second expansion nut 210 is fixedly connected to the other side of the vertical wall 206, a positioning nail 211 is embedded in the through hole 208, and the first groove 201, the second groove 202, the first thread groove 203, the first expansion nut 204, The connection frame 205, the vertical wall 206, the bolt 207, the through hole 208, the second thread groove 209, the second expansion nut 210 and the positioning nail 211 are arranged. First, installation holes are respectively opened on the slope surface and the slope foot side of the soil body, and a fixing hole is opened on the slope foot side, and the first expansion nut 204 and the second expansion nut 210 are embedded in the protection hole, and the connection frame 205 is attached to the slope foot side of the soil body, and the positioning nail 211 is installed through the through hole 208 to ensure the stability of the connection frame 205. Thereafter, the two sides of the connection frame 205 are embedded. The support plate 1 is assembled, and the bolt 207 is threadedly connected in the first thread groove 203. The support plate 1 is further reinforced by the tightening effect of the bolt 207. Thereafter, the vertical wall 206 is embedded in the second groove 202 and fits tightly with the slope foot of the soil. The stability of the vertical wall 206 is ensured by the connection between the second thread groove 209 and the bolt 207. Through the above structure and installation steps, while ensuring economy, the support mechanism 2 can effectively support and reinforce the slope surface and slope foot of the soil, prevent the soil from slipping or collapsing, and provide a stable support effect.

[0020] Furthermore, four groups of the first thread groove 203 and the first expansion nut 204 are provided, and the positions of the first thread groove 203 and the first expansion nut 204 are relatively positive. Through the setting of the first thread groove 203 and the first expansion nut 204, the first expansion nut 204 is embedded in the soil. The first expansion nut 204 is a specially designed nut, which is fixedly connected to the support plate 1 on the other side of the support mechanism 2. The first thread groove 203 is located on one side of the support plate 1 and is provided with threads inside. The main function of these threads is to provide a fixed point for installing and connecting bolts 207. Through the tightening of the bolts 207, the first thread groove 203 can ensure that the support mechanism 2 is firmly fixed on the support plate 1 to prevent movement or loosening in geological engineering applications.

[0021] Furthermore, four groups of the second thread groove 209 and the second expansion nut 210 are provided, and the positions of the second thread groove 209 and the second expansion nut 210 are relatively straight. The internal threads of the second thread groove 209 and the second expansion nut 210 are connected. Through the setting of the second thread groove 209 and the second expansion nut 210, the second thread groove 209 is located inside the vertical wall 206, and is provided with threads inside. These threads can be used in conjunction with the second expansion nut 210 to add additional fixing points and connection points on the support plate 1. Through the tightening of the second thread groove 209 and the second expansion nut 210, the overall stability of the support mechanism 2 can be enhanced, which is particularly important in geological environments that need to withstand greater forces and extrusion pressures.

[0022] Furthermore, two groups of positioning pins 211 are provided, and one side of the positioning pins 211 is embedded in the interior of the soil. Through the setting of the positioning pins 211, the positioning pins 211 fix the connecting frame 205 at the foot of the slope to ensure the stable fixation of the connecting frame 205. At the same time, the positioning pins 211 are embedded in the through holes 208 to accurately position and fix the connecting frame 205 and the support plate 1 to prevent the displacement of the connecting frame 205.

[0023] Furthermore, two groups of vertical walls 206 are provided, and one side of the vertical wall 206 is tightly fitted with the toe of the slope. By providing the vertical wall 206 and adding detachable vertical walls 206, a buttress-type support structure is formed. Compared with the traditional gravity retaining wall, the buttress-type support structure directly supports the soil through the vertical wall 206, has a stable structure, can withstand greater soil pressure, and prevent soil slippage and collapse. Moreover, this construction process is relatively simple and can be completed quickly, which is conducive to shortening the construction period.

[0024] Working principle: First, installation holes are opened on the slope surface and the foot of the slope of the soil body respectively, and a fixing hole is opened on the side of the foot of the slope, and the first expansion nut 204 and the second expansion nut 210 are embedded in the protective holes, and the connecting frame 205 is attached to the side of the foot of the slope of the soil body, and the positioning nail 211 is installed through the through hole 208 to ensure the stability of the connecting frame 205. Thereafter, the support plate 1 is embedded on both sides of the connecting frame 205, and the bolt 207 is threaded into the first thread groove 203. The support plate 1 is further reinforced by the tightening effect of the bolt 207. Thereafter, the vertical wall 206 is embedded in the second groove 202 and fits tightly with the foot of the slope of the soil body. The stability of the vertical wall 206 is ensured by the connection between the second thread groove 209 and the bolt 207. Through the above structure and installation steps, while ensuring economy, the support mechanism 2 can effectively support and reinforce the slope surface and foot of the soil body, prevent the soil from slipping or collapsing, and provide a stable support effect.
