| description | The utility model relates to the technical field of pavement drainage. The utility model relates to a drainage structure, in particular to a dispersed drainage structure. The structure comprises a drainage asphalt layer, a waterproof bonding layer, a lower bearing layer, a permeable pavement layer and an impermeable layer, the lower bearing layer, the waterproof bonding layer and the drainage asphalt layer are sequentially laid from bottom to top, the impermeable layer is arranged on an earth shoulder, the permeable pavement layer is arranged on the impermeable layer, and the elevation is keptto be 0-3 cm lower than that of the drainage asphalt layer; or the permeable pavement layer is not arranged, and the elevation of the permeable pavement layer is 1.5-6cm lower than that of the drainage asphalt layer. Rainwater is collected to the road side through a drainage channel in the drainage asphalt layer, is drained from the side slope through the laid permeable pavement layer or the upper surface of the impermea |
