摘要
The present invention induces a temporary storage of rainwater and infiltration into the basement by filtering the rainwater, ensuring high quality water resources, reducing inundation and flood damage, and inducing excellent underground penetration to protect the natural ecosystem by normalizing the water cycle About the system,;Its basic composition consists of a nonwoven fabric that is dug up into a suitable size on its upper surface after digging; A filter layer laid on the upper surface of the nonwoven fabric with a predetermined thickness and filtering contaminants contained in rainwater; A manhole which is installed in the filter layer laid on the upper surface of the nonwoven fabric and allows a plurality of drain holes to be drilled in the circumferential wall, wherein the filter layer is refilled in the inner space; A planting part made of trees, plants, etc., which are planted on the upper side of the filter layer filled in the manhole; A water supply pipe passing through the upper end of the manhole and flowing rainwater flowing down from an adjacent manhole or an adjacent drip tray to the upper side of the manhole, wherein the rainwater flows into the manhole and is stored and passes through a filter layer filled in and around the manhole. It also has technical features that allow contaminants to be filtered and penetrate existing soils.;Storm water, storm filtration, underground penetration, manhole
