A prefabricated vegetative drainageway and a construction method thereof are provided to construct an easy vegetative and eco-friendly drainageway by forming a drainageway with blocks which are manufactured with water-permeable concrete and formed to have the impermeable bottom and side by spraying an admixture of water, cement and polymer and to clean up blocks easily by installing an open type block between blocks. A prefabricated vegetative drainageway is formed by constructing the bottom(10) with cast-in-place concrete to be projected upward from both ends, piling up blocks(20) on the upper part of the bottom and installing an open type block(30) between the blocks. The block is made of water-permeable concrete, which is mixed with yellow soil, germanium, charcoal, etc., and composed of a main body and a projection projected upward from both ends of the main body. A construction method for a prefabricated vegetative drainageway comprises the steps of pit-excavating, spreading an auxiliary base layer, sand, etc. and keeping at a level, installing blocks on the bottom to adhere closely to each other, spraying an admixture of water, cement and polymer between the blocks to cut off a gap between blocks, locating an open type block between the blocks to discharge rainwater, spreading soil on the blocks and guiding the vegetation of lawn. |
