A revetment block is provided to increase the connection performance of blocks and elevate the stability by forming the combining projection and the combing groove at front/rear sides and left/right ends of the body. A revetment block is composed of plural vegetation holes(200) vertically penetrated in a body(100) shaped like a large plate; a combining projection(300a) and a combining groove(300b) mutually corresponded at front/rear sides and left/right ends of the body for fitting-connection; a combining hole(400) horizontally bored from the inside of the vegetation hole to the combining projection and the combining groove; and bolt and nut members(600a,600b) formed to mutually fix the combining projection and the combining groove connected through the combining hole. The combining projection is projected like a wide-inside and narrow-outside shape, and the combining groove is recessed like a narrow-inside and wide-outside shape. |
