A vegetation block for a waterway is provided to construct an ecological waterway strongly and stably by connecting in the matrix type. The vegetation block(10) is manufactured by mixing coarse aggregate, cement, water and a mixture in the appointed ratio, pouring in a mold, setting up a vibration and compressing at the appointed pressure. Hereon the vegetation block contains a primary incline plane(13) formed by inclining corresponding sides of four sides connecting an upper plane(11) and a lower plane(12) downward from the top at the appointed angle of inclination, a secondary incline(14) formed by inclining the corresponding opposite sides upward from the bottom at the appointed angle of inclination, and a vegetation groove(15) formed on the upper plane to the appointed depth. The construction method of an ecological waterway using vegetation blocks comprises the steps of leveling the bottom, the incline and the crown of a waterway and arranging vegetation blocks in the matrix type on the bottom, the incline and the crown of the waterway. |
