PURPOSE: A coupling structure of a vegetative revetment block frame is provided to maximize durability and reliability since even if a welded part is separated by serious impact, a connecting ring is not separated. CONSTITUTION: A coupling structure of a vegetative revetment block frame comprising a bent unit(31). The bent unit is formed in a "Γ" or "⊃" shape. The bent unit is formed on the leading end of a ⊂-shaped connecting ring(3). The ⊂-shaped connecting ring is welded to an inner frame(2), which is arranged in a vegetative revetment block. |
