Rain garden construction method having vegetative growth palpation and nonpoint pollutants reduction

摘要

the present invention is to supply a continuous planting the case of rain, the stored water the plant vegetation growth is promoted, and the lower the ambient temperature rises to the natural evaporation of water, the boiling point with impurities of precipitation and adsorption It provides a construction method of the rain garden facility with a reduction of pollutant removal promoting vegetation growth to be achieved by reducing and non-material. Comprising the steps of securing appropriate if, according to the embodiment of the invention, the housing cavity by a predetermined depth by conducting a predetermined area on the floor to be discarded teot deuleoseoge the complex garden vegetation; The first and second water collection sump for rainwater catchment and the other side of his monitoring of vegetation each magazine side steps of the installation; Crushing gravel or rubble on the ground and vegetation magazine for the construction phase hydration layer of a certain height; Step buried in the lower portion of the capillary moisture supply layer board and put to expose the top of the board to the outside of the capillary and the hydration layer; Putting install the siege on one side of the entrance of the drain after installing drain yugonggwan having a plurality of inlet hole on the upper surface of the hydration layer yugonggwan, and connect the other end of the drain yugonggwan waste, to fix a second home for precipitating impurities and step; Backfilling the earth and sand to the upper surface of the water supply to the buried layer by placing a drain in yugonggwan tosacheung; is characterized in that the construction, including the ;
