The continuous acceleration of the urbanization process results in the continuous reduction of permeable floors, thereby bringing a series of rain and flood management problems. Therefore, the construction and transformation of the sponge city become an important means for coping with and managing the risk of urban storm flood disasters. In the sponge city construction and transformation process, the road green belt is an important place for implementing low-influence development measures such as seepage, stagnation, storage, purification, use, drainage and the like because the road green belt is a non-hardened green area. The road green belt is modified mainly by taking slow release and source dispersion control as main planning and design concepts, and grass planting ditches, rainwater gardens, sinking green lands and the like as main measures to realize the accumulation and utilization of rainwater. However, grass planting ditches, rain gardens, sinking greenbelts and the like all require that the ground elevation of the road greenbelts is lower than that of motor vehicles and bicycle lanes, which causes the following defects in the technology of grass planting ditches, rain gardens, sinking greenbelts and the like: firstly, because the planting of the existing green belt plants is finished, the existing green belt has great influence on the green belt plants when the existing green belt is used for implementing the techniques of grass planting ditches, rain gardens, sinking green lands and the like, and the popularization and application difficulty and the implementation cost are increased; secondly, the design that the green belt is lower than the road surface is not beneficial to the green belt to play the role of isolating harmful and toxic gas and noise; thirdly, the green belt is lower than the road surface, so that water is easily accumulated on the green belt, the green plants are drowned, and the selection difficulty and maintenance cost of the green plants are increased; in addition, the green belt is lower than the road surface, so that the aesthetic and safe driving visual habit of people is not met, and the difficulty of road design and landscape design is increased; finally, the green belt is lower than the road surface, and the accumulated water easily permeates into the roadbed, so that the bearing capacity of the road is reduced, and the durability of the road is influenced.
In order to ensure the normal growth of the plants in the urban road green belts in the non-rainfall period, the water requirement of the plants is often required to be met through manual irrigation, however, the road green belts are wide in distribution range and high in dispersion degree, so that the problems of poor drought resistance, insufficient irrigation water source, inconvenience in management and maintenance, high labor cost, large investment of infrastructure when adopting a spray irrigation or drip irrigation mode and the like are caused in the road green belts in the daily management and maintenance process.
