Sponge city permeable pavement structure

The utility model belongs to the technical field of building construction, and particularly relates to a sponge city permeable pavement structure which comprises a surface layer, a drainage layer for drainage, a cushion layer for stable bearing, a bearing layer and a roadbed layer are sequentially laid at the bottom of the surface layer from top to bottom, and the bearing layer is used for achieving the purpose of high overall compressive bearing capacity. A plurality of reinforcing assemblies are arranged on the inner side of the bearing layer and are uniformly distributed, so that the purpose of improving the bearing capacity and the deformation resistance is achieved; the multiple reinforcing assemblies are arranged, under the action of the T-shaped pieces, the reinforcing assemblies can be spliced for use, machining and transportation of the reinforcing assemblies are facilitated, after the reinforcing assemblies are spliced, a rectangular cavity is formed in the four reinforcing columns and the four conn
