Road permeating, separating and filtering structure

The utility model discloses a road permeating, separating and filtering structure, and relates to the field of urban road drainage, the road permeating, separating and filtering structure comprises a road surface layer, a supporting layer is arranged under the road surface layer, a permeable filtering layer is arranged under the supporting layer, a foundation soil layer is arranged under the permeable filtering layer, and symmetrical curbstones are arranged on two sides of the road surface layer. The side, away from the road surface layer, of the curbstone is the ground, the road surface layer is formed by paving water permeable bricks, the water permeable bricks are silicate bricks, and the supporting layer is formed by pouring water permeable concrete. Rainwater penetrates through the water permeable bricks and then passes through the supporting layer, due to the fact that the supporting layer is formed by pouring water permeable concrete, the rainwater directly permeates into the water permeable filtering
