[0026] Working principle: Green permeable pavement is a specially designed pavement, which is paved with permeable materials and has good permeability. This pavement can quickly filter rainwater, floods and natural precipitation and infiltrate them into the ground, thereby protecting the environment and preventing flood disasters. It can effectively alleviate the pressure on the urban drainage system, let rainwater return to nature, and improve the urban ecological environment. The fixed grid 4 is located between the permeable asphalt layer 1 and the permeable surface brick layer 5, which can significantly improve the bearing capacity and durability of the pavement. The surfaces of the permeable asphalt layer 1 and the permeable surface brick layer 5 have a large porosity, which can quickly drain rainwater into the base layer below. The semi-rigid base layer 7 has a high stiffness and a strong load diffusion capacity, which can effectively disperse and withstand the pressure from vehicle traffic loads and maintain the flatness and stability of the pavement.
