Permeable pavement drainage structure
The invention belongs to the technical field of road drainage design, and particularly relates to a permeable pavement drainage structure. The drainage structure comprises a drainage road, a motor-driven and non-motor-driven isolation belt and vertical kerbs arranged between the drainage road and the motor-driven and non-motor-driven isolation belt. The drainage road sequentially comprises a roadbed, a non-permeable pavement lower-layer structure and a permeable pavement upper-layer structure from bottom to top, wherein permeable pores which are communicated with one another are formed in thepermeable pavement upper-layer structure; and 1.5%-3% of a cross slope is arranged on the plane of the drainage road. A first drainage hole and a second drainage hole are formed in the side wall of the vertical kerb, and the upper surface of the permeable pavement upper-layer structure is located between the upper edge and the lower edge of the first drainage hole; the upper surface of the non-permeable pavement lower layer structure is located between the upper edge and the lower edge of the second drainage hole, and the upper surface of a filler in the motor-driven and non-motor-driven isolation belt is lower than the lower edge of the first drainage hole. By arranging a plurality of drainage ways, the road surface drainage speed is increased, and rainwater is collected and drained intothe motor-driven and non-motor-driven isolation belt and is retained in the storage facility after being purified.
本发明属于道路排水设计技术领域，具体涉及一种透水路面排水结构。包括排水道路、机非隔离带和设置在排水道路和机非隔离带之间的立缘石。排水道路自下而上依次包括路基、非透水路面下层结构和透水路面上层结构，透水路面上层结构内具有相互连通的透水孔隙；排水道路平面设有1.5％‑3％的横坡。立缘石的侧壁设置有第一排水孔和第二排水孔，透水路面上层结构的上表面高度位于第一排水孔的上边缘与下边缘之间；非透水路面下层结构的上表面位于第二排水孔的上边缘与下边缘之间，机非隔离带内填充物的上表面高度低于第一排水孔的下边缘。通过设置多个排水途径，加快了路面排水速度，雨水经汇集排至机非隔离带内，净化后留滞存储设施。
