detailed description

Below in conjunction with accompanying drawing, the utility model is further described, and the protection scope of the utility model is not limited to the following:

As shown in Figures 1 and 2, a newly-built sponge city on a plain includes a planning area and a ring river 1 surrounding the outside of the planning area. A secondary main road 2 and multiple parallel roads are laid in the planning area. The main road 3, the main road 3 is set horizontally, the secondary main road 2 is located in the middle of the planning area, the secondary main road 2 is connected to the main road 3, and the secondary main road 2 is laid perpendicular to the main road 3. A number of auxiliary roads 4 are laid between them. The auxiliary road 4, the main road 3 and the secondary main road 2 divide the planning area into a plurality of patch-shaped building areas 5. The main road 3, the auxiliary road 4 and the secondary road The main road 2 is a permeable road surface, and both sides of the main road 3, the auxiliary road 4 and the secondary main road 2 are provided with a sunken green belt 6, and the horizontal height of the sunken green belt 6 is lower than that of the building area 5 , so that the excess rainwater in the 5 can flow into the sunken green belt 6 by itself through the pipeline, avoiding the urban waterlogging caused by rainwater deposition. Since the main roads 3 are parallel to each other, their extension direction is the same as the main direction of the local prevailing monsoon, which can form an urban draft, which is conducive to the diffusion and transmission of urban polluting gases, avoiding urban air pollution, and ensuring the physical and mental health of residents.
