The design of grid shaped cast-in-situ concrete and oval petal shaped blocks connected with each other is adopted to realize that the entire bearing layer of the floor is a network structure with stable structure, high bearing performance and high durability, forming a sponge floor system. The surface bearing body of the porous lawn concrete pavement system reinforced by continuous steel bars cast on site is a concrete pile connected at the lower part and independent at the upper part, and the bottom layer is continuous (reinforced) concrete, with the maximum bearing weight of about 60 tons. The design of connecting the surface planting cavities realizes the stable structure, high bearing performance and high durability of the lawn planting system.
