PURPOSE: A rainwater infiltrating structure is provided to secure water resources and to prevent flood damage by guiding penetration of rainwater in underground after filtering. CONSTITUTION: A rainwater infiltrating structure comprises a sand layer(40), a penetrating body layer, a penetration tube(20), and a soil layer(30). The sand layer is formed in the lower layer of the infiltrating structure. The penetrating body layer is formed on the top of the sand layer and stores the infiltrated rainwater. A plurality of penetrating bodies(10) in which a penetration space is formed, is laminated so that rainwater can be penetrated in the penetrating body layer. The soil layer is formed in the upper layer of the penetration tube. |
