Rock slope plays an important role in roadbed engineering, and its stability has a direct impact on the overall stability of the roadbed.

[0003] Rock slope is characterized by its hard rock composition, which can withstand high pressure and load. Due to the properties of the rock, rock slope exhibits good durability and stability during long-term use. However, the maintenance and repair costs of rock slope can be relatively high, especially when large-scale rock excavation or reinforcement work is required.

[0004] As application number 202321894420.X, by setting a reinforcement support, the edge position of the slope is basically reinforced to provide support for the internal reinforcement of the slope. By setting a fixed screw, the middle position of the slope is further reinforced to ensure the stability of the slope. By setting a waterproof layer, a large amount of water is prevented from entering the soil of the slope, avoiding landslides and ensuring the safety of the surrounding environment. By setting a fixed layer, the stability of the slope is further reinforced, and the appearance of the slope is improved. However, the device still has some defects.
