Problems solved by technology
However, the traditional permeable pavement structure is very easy to block. When the rainstorm hits, the drainage permeability coefficient is low, and the drainage speed is slow. If the drainage is not timely, it will easily cause the rainwater on the road to rise rapidly, and eventually lead to the phenomenon of "urban sea view" in many domestic cities.

Abstract
The invention discloses a concrete permeable pavement structure with a multi-layer horn mouth structure, which comprises a backflushing system, a concrete surface layer and a concrete cushion layer, and the concrete cushion layer and the concrete surface layer are sequentially laid on a roadbed from bottom to top; the concrete cushion layer comprises a plurality of layers of aggregate arranged in a gradient grading mode, and the radius of each layer of aggregate is reduced from bottom to top. And the backflushing system is arranged in the concrete cushion layer. The structure is simple, laying is convenient, water drainage, water storage, active dredging and timely blocking prevention are organically combined, the water permeability performance of the road surface is effectively improved, and the water drainage efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of road materials and structures, and in particular relates to a concrete permeable pavement structure with a multi-layer bell mouth structure. Background technique [0002] The construction of sponge cities follows the principles of ecological priority, combining natural ways with artificial measures, and on the premise of ensuring the safety of urban drainage and waterlogging prevention, to maximize the accumulation, infiltration and purification of rainwater in urban areas, and to promote the utilization of rainwater resources. It can absorb, store, seep and purify water when it rains, and release and use the stored water when needed, so as to realize the free migration of rainwater in the city. However, the traditional permeable pavement structure is very easy to block. When the rainstorm hits, the drainage permeability coefficient is low, the drainage speed is slow, and the drainage is not timely, which...
