ABSTRACT:
An erosion control revetment and wall made from preformed blocks which are secured to elongate support members by interlocking sleeves. The block is formed with transversely extending slots which extend from the top end to the bottom end of the block and have an enlarged opening on the top end for receiving a tubular sleeve which encircles the elongate support members. The outer diameter of the sleeve is snugly received within the enlarged opening, but is larger than the width of the remainder of the slot, preventing unintended removal of the block from the support member. The elongate support members may be semi-rigid rods or cables. The revetment is formed from alternating rows of blocks which are offset by one elongate support member relative to blocks in adjacent rows. Alternatively, the blocks may be assembled into a wall having vertically aligned blocks or blocks which are offset relative to one another in adjacent rows.
