Description

Technical Field

[0002] Landslide subgrade is a common type in geological disasters, which poses a serious threat to the safety and reliability of roads and transportation systems. Therefore, in some sections, corresponding protection structures are needed to protect the subgrade.

[0003] A device for preventing landslides on highway slopes with the publication number of CN211898468U includes a subgrade and a highway body laid on the top of the subgrade, and further includes: a fixing plate arranged on the slope of the subgrade, one end of the fixing plate is fixed to the edge of the highway body, and the other end is provided with a V-shaped support plate embedded into the subgrade; a protection net is also arranged between the fixing plates. The device for preventing landslides on highway slopes with the above structure effectively avoids problems such as the loss of fine soil and landslides on highway slopes that endanger traffic safety, and has low manufacturing cost, simple structure, and is easy to promote and use.

[0004] Regarding the above related technologies, the inventor believes that when installing the fixing plate for protecting the subgrade, it is only connected to the highway body through bolts and connected to the subgrade through the V-shaped support plate. Since both lack a friction structure, loosening may occur over time, resulting in the loosening of the fixing plate, which in turn will affect the protection effect on the subgrade. For this reason, we propose a treatment and protection retaining structure for landslide subgrade. Content of the Utility Model
