Highway engineering strongly-weathered rock slope ecological protection plate

The utility model provides a highway engineering strong weathered rock slope ecological protection plate which comprises a fixed seat, inserting cones, sliding grooves, sliding holes, locking holes, a sliding plate, a clamping plate, locking bolts and a collectable filtering protection plate structure, and the inserting cones are fixed to the four corners of the bottom end of the fixed seat through bolts respectively. The fixing seat, the inserting cone, the U-shaped connecting seat and the protection plate are arranged in a matched mode, so that the U-shaped connecting seat can make contact with the upper end of a side slope needing to be protected in the protection process, and it is prevented that a gap exists between the protection plate and the side slope in the use process, and the protection effect is affected; through arrangement of a U-shaped connecting base, a protection plate, a fixing plate, a supporting plate and a collecting and filtering plate, green plants can be planted at the upper end of th
