PURPOSE: A vegetation revetment block is provided to form the advantageous base for vegetation, to prevent the loss of soil by rainwater and to increase structural stability by improving the self-strength of a vegetation revetment block. CONSTITUTION: The vegetation revetment block(1) is composed of a body formed to have an I-shaped outward shape to the appointed thickness and a concrete admixture mixed with cement, water, gravel, sand and powered limestone. Wherein the body(2) is provided with a vegetation hole(3) perforated vertically and attached with eco-friendly earth, a projection(4) is projected to the top of the body(2) around the vegetation hole(3), projections(5a,5b) are formed on the upper and lower parts of the body(2) and curved horizontally against the body(2) to prevent the loss of covering soils paved on the top of the vegetation revetment blocks(1) by the projection(4) and the projections(5a,5b) along an incline and to increase the self-strength of the vegetation revetment block(1), and a vegetation space is formed between the upper and lower parts of the vegetation revetment blocks(1). |
