The invention discloses a permeable-water-storage-drainage type green paving system based on a sponge city. The pavement system is composed of a pavement paving unit, a water storage unit and a drainage unit arranged on the roadbed. The pavement paving unit, the water storage unit and the roadbed are arranged layer by layer from top to bottom, and the drainage unit is located on the road surface. The side of the unit and the water storage unit; a waterproof layer is arranged on the roadbed; the road pavement unit is composed of a road pavement layer and a plurality of permeable pipes vertically penetrating the road pavement layer; the water storage unit is composed of a plurality of steel bars The water storage cavity constructed by cement concrete is spliced together. Compared with the existing technology, the system has the advantages of strong pavement bearing capacity, high water permeability, easy maintenance and good durability; multi-functional and efficient integration of permeable-water-storage-drainage, etc., to achieve green utilization of water resources; good water storage and water retention effect, The stable roadbed, less road surface disease, long service life and many other advantages can effectively solve or alleviate the urban "heat island effect". |
