Abstract

The invention relates to a sponge city drainage structure and a sponge city water circulating method. A road structure comprises a permeable concrete layer, a mortar leveling layer, a graded broken stone layer and a plain soil layer from top to bottom in sequence; support grids are arranged in the mortar leveling layer; a guide pipe for drainage is arranged in the graded broken stone layer; drainage ditches and road traffic stones are arranged on the two sides of the road layer structure; the drainage ditches are positioned between the road layer structure and the road traffic stones; drain pipes are arranged at the bottoms of the drainage ditches; water storage cavities are formed in the road traffic stones, and communicate with the drainage ditches through drainage holes; the other sides, relative to the drainage holes, of the water storage cavities communicate with green belts through permeable holes; the green belts comprise pebble beds, planting soil layers and green broken stonelayers in sequence from top to bottom; drainage pipes for drainage are arranged in the green broken stone layers; a water collecting pool is connected with a main pipe; and the guide pipe, the drain pipes and the drainage pipes communicate with the main pipe. The structure achieves the effects of reducing the city road ponding conditions and improving the rainwater utilization rate.

Description

technical field [0001] The invention relates to the technical field of sponge cities, in particular to a sponge city drainage structure and a sponge city water circulation method. Background technique [0002] Sponge city is to build the city into a sponge-like body that can absorb, store, infiltrate and purify water, resolve natural disasters caused by rainwater, and make it a water-elastic city that can be retracted freely. The construction of a sponge city is not to overthrow and replace the traditional drainage system, but to reduce and supplement the traditional drainage system, and to maximize the role of the urban water supply and drainage network itself. [0003] Traditional road construction relies on ordinary bricks or concrete paving. When it rains, the bricks and concrete do not absorb or seep water. The road surface is wet and slippery. The drainage of rainwater depends on urban drainage pipes. Often due to heavy rain, heavy rain, large displacement, and blocka...
