The structure composing the inventive device comprises retaining plates spaced along a protected slope and buttress plates arranged in the spaces on the side of the slope and oriented towards the ends of said retaining plates. Faceplates are arranged on the opposite side with respect to said buttress plates and inclined thereto along the height of the wall. Said faceplates are fixed to each other and to the buttress plates in such a way than they form a single rigid hollow frame which has a triangular cross-section.
