Pavement paving structure convenient for drainage

Abstract

The utility model discloses a pavement paving structure convenient for drainage, and belongs to the technical field of pavement paving, the pavement paving structure comprises a cushion layer, a base layer and a permeable surface layer, the cushion layer, the base layer and the permeable surface layer are sequentially paved from bottom to top, the upper end face of the base layer is a slope surface with the slope facing the two sides and the gradient not larger than five degrees, and the upper end face of the permeable surface layer is flat and does not have the slope surface; a drainage pipe is embedded in the upper end face of the base layer and comprises a rectangular pipe body and a connecting pipe, a plurality of water seepage seams are formed in the upper end face of the rectangular pipe body, and water collecting channels are fixedly arranged on the two sides of the base layer. When falling onto the permeable surface layer, rainwater can directly seep down and flow into the base layer, and is discharged into the water collecting channels on the two sides along the slope surface of the upper end surface of the base layer, so that the permeable surface layer serving as the road surface can ensure the smoothness and water accumulation is avoided; water in the permeable surface layer can enter the drainage pipes through the water seepage seams to be drained, and the drainage burden of the base layer is relieved.
