A structure of a revetment block in a river is provided to prevent a landslide on a slope by integrally connecting the revetment blocks with assembling members and decreasing the flow velocity of rainwater. A revetment block structure includes revetment blocks(10) continuously installed on a slope and vertically and horizontally arranged, a block seating plate(20) fixed to the slop to place the revetment block, and left and right support bars supporting the left and right sides of the revetment block. The left support bar is vertically fixed in the slope, and the block seating plate is fixed into the ground in integrating an anchor hole of an assembling cover(14) with a support hole. An anchor is inserted to the slope through the anchor hole and the support hole, and the assembling cover is placed in a cover seat(16) of the revetment block. The revetment blocks are arranged and fixed to the slope by fitting the anchor in placing the anchor hole in an extension line of an assembling hole(17). Flow of rainwater is decelerated with recessed parts(11) and protruded parts(12), and rainwater is streamed through a drain recessed groove(13) to the river. |
