Municipal road structure based on sponge city

The municipal road structure based on the sponge city comprises a road surface, a green belt is arranged on the outer side of the road surface, a curb is arranged on the side wall of the road surface, a drainage opening is formed in the outer wall of the curb, and the processing assembly is arranged on the inner side of the curb and comprises a permeation assembly arranged on the inner side of the curb. When rainwater falls on the road surface, drainage treatment needs to be conducted on the rainwater, the rainwater falls on the abrasion-resistant layer and permeates towards the drainage layer through the abrasion-resistant layer, the abrasion-resistant layer is made of abrasion-resistant materials, and when a vehicle runs on the surface of the abrasion-resistant layer, the road surface can be made to be firmer and more durable; rainwater permeates to the filtering layer, impurities in the rainwater are filtered through the filtering layer and prevented from flowing to soil along with the rainwater, the rainw
