[0020] A prefabricated retaining wall comprises a prefabricated wall panel 1, wherein a planting positioning hole 2 is formed through the surface of the prefabricated wall panel 1, a water guide groove 3 is formed on the outer surface of the prefabricated wall panel 1, a connecting groove 5 is formed on the surface of the prefabricated wall panel 1, a rubber plug 4 is embedded and connected to the inner side of the connecting groove 5, a connecting screw 6 and a positioning nut 7 are arranged on the inner side of the connecting groove 5, a drainage hole 8 is formed through the surface of the water guide groove 3, and a splicing support effect between the prefabricated wall panels 1 is achieved through the connection between the prefabricated wall panel 1 and the connecting groove 5 and the connection between the connecting screw 6 and the positioning nut 7, and a protective effect is achieved on the connecting screw 6 and the positioning nut 7 in the connecting groove 5 through the embedded connection of the rubber plug 4 and the connecting groove 5, so as to avoid direct contact between the connecting screw 6 and the positioning nut 7 and oxidation and rusting of the connection between the connecting screw 6 and the positioning nut 7.

[0021] Furthermore, the prefabricated wall panel 1 is composed of three parts, and the three parts of the prefabricated wall panel 1 form a curved slope. The drainage hole 8 penetrates the inner wall of the water guide groove 3 of the prefabricated wall panel 1 away from the road surface. Through the connection between the prefabricated wall panels 1, under the action of the prefabricated wall panels 1, it is convenient to assemble them in the construction site. Under the action of the prefabricated wall panels 1, the roadside slopes can be protected to avoid soil erosion or impact and pollution to the road surface. Under the action of the drainage hole 8, the water on the back of the prefabricated wall panel 1 can be discharged and diverted.

[0022] Furthermore, a planting positioning hole 2 is opened in the middle position of the prefabricated wall panel 1, and the opening angle of the planting positioning hole 2 on the prefabricated wall panel 1 is perpendicular to the ground. Trees are arranged on the surface of the prefabricated wall panel 1 through the planting positioning hole 2. Through the connection between the planting positioning hole 2 and the prefabricated wall panel 1, under the action of the planting positioning hole 2, it is convenient for the trees to penetrate the prefabricated wall panel 1 and be planted underground. Under the action of the trees, the prefabricated wall panel 1 can be limited to the slope position. Compared with the traditional method of cement pouring, this method is more convenient to operate and reduces the impact on the environment.

[0023] Furthermore, the trees pass through the surface of the prefabricated wall panel 1 and are connected to the ground through the planting positioning holes 2. The two ends of the prefabricated wall panel 1 are respectively in contact with the slope and the road surface. The trees are highly stratified under the action of the slope angle, so that the trees receive a large area of ​​sunlight and grow and develop better. The use of the prefabricated wall panel 1 on the slope and the planting of trees can effectively prevent the loss of soil on the slope and improve the safety performance of the road surface. Under the action of the planting positioning holes 2 and the trees, the limited support operation of the installation position of the prefabricated wall panel 1 on the slope is convenient.

The water channel 3 and the planting positioning holes 2 are distributed correspondingly. Through the opening of the water channel 3 and the prefabricated wall panel 1, under the action of the water channel 3, the water acting on the prefabricated wall panel 1 can be diverted to irrigate the trees at the planting positioning holes 2, and prevent rainwater from remaining on the surface of the prefabricated wall panel 1 and causing corrosion on the surface of the prefabricated wall panel 1.

[0025] Furthermore, the material of the rubber plug 4 is rubber, and the rubber plug 4 is plugged into the prefabricated wall panel 1 through the connecting groove 5. The connecting groove 5 is distributed in four groups around the prefabricated wall panel 1. Through the plugging of the rubber plug 4 and the connecting groove 5, under the action of the rubber plug 4, the connecting groove 5 can form an enclosed space.

The connecting screw 6 is rotatably connected through the thread and the positioning nut 7. Under the connection between the connecting groove 5 and the connecting screw 6, the connection between the connecting screw 6 and the positioning nut 7 realizes the connection and support effect between the prefabricated wall panels 1, achieves the installation and splicing effect between the prefabricated wall panels 1, and improves the convenience of its construction operation.

[0027] Working principle: When assembling the prefabricated wall panels 1, first place the prefabricated wall panels 1 on the slope at the corresponding position. The prefabricated wall panels 1 are connected by the connecting screws 6 and the positioning nuts 7. After the connection, the rubber plugs 4 are used to seal the connecting grooves 5. Then, trees are planted at the planting positioning holes 2. Under the action of the water guide grooves 3, the water entering the prefabricated wall panels 1 can be diverted to irrigate the trees and effectively avoid the residue of water on the surface of the prefabricated wall panels 1. Under the action of the trees, the prefabricated wall panels 1 can be limited and supported on the slope to improve the stability and effect of the use of the prefabricated wall panels 1. The trees are highly layered and distributed on the prefabricated wall panels 1, so that the trees receive a large area of ​​sunlight and grow better.
