A vegetation revetment block is provided to improve ecological effects by constructing on the slope of a bank, to beautify a river or a stream, to steadily combine an arc protrusion unit of an upper edge of the revetment block with an arc combining groove of the revetment block, to reduce flow speed of rainwater by forming recessed units at the front, rear, left, and right sides and the upper edge of the revetment block, and to secure a vegetating space properly. A vegetation revetment block(100) comprises arc protrusion units(110) formed on every lateral side of the revetment block built on the slope of a bank; a drain path recessed to a certain width and depth along the length on an upper edge of the revetment block to be combined with another revetment block; a through-hole(130) formed at the middle of the upper surface of the revetment block to be bored to the lower surface; a through-hole formed at the middle portion to be combined with four revetment blocks; an upper layer(100a) formed at the upper side of the revetment block by mixing clay of 65~75 wt%, sand of 34.85~24.4 wt%, soil hardener of 0.1~0.5 wt%, and grass seeds of 0.05~0.1 wt%; a recessed unit(140) formed at the front, rear, left, and right sides of the upper surface of the revetment block as a vegetation space; the arc protrusion unit formed with sills on both sides; an arc recessed unit(150) formed between the arc protrusion units with sill fixing units at both sides; and a lower layer(100b) formed at the lower side of the revetment block by mixing clay of 55~60 wt%, sand of 33.9~20 wt%, crushed stone of 6~8 wt%, cement of 5~9 wt%, and soil hardener of 0.1~3.0 wt%. |
