PURPOSE: A coupling apparatus for revetment blocks is provided to facilitate the connection of revetment blocks and enable the strong coupling of the revetment blocks. CONSTITUTION: A coupling apparatus for revetment blocks comprises a metal support piece(110), first, second, third, fourth connectors(120a,120b,120c,120d), and a coupler. The metal support piece is installed in order to be integrated and molded with a revetment block(100). The first, second, third, and fourth connectors are made of metal. The first, second, third, and fourth connectors are fixed in the metal support piece on the front, rear, left, and right of the revetment block and are projected horizontally. The coupler is inserted into the multiple coupling grooves formed in the first, second, third, and fourth connectors. |
