Roadbed slope protection device

The utility model belongs to the technical field of roadbed side slope protection, and particularly relates to a road roadbed side slope protection device which comprises a side slope body, a plurality of protection positions are sequentially connected and distributed on the side slope body, and each protection position is provided with a supporting guardrail and a protection device which are distributed from outside to inside. The supporting guardrail comprises a protection mechanism with a protection function and a supporting mechanism used for axially and obliquely supporting the inner side of the protection mechanism, and the protection device is installed between the protection mechanism and the top end of the slope body. The protection device is supported through the protection mechanism and the supporting mechanism, the situation that the protection device covers the slope of the slope body is avoided, when rockfall occurs and makes contact with the protection device, the protection device rebounds the
