Background

At present, most of the existing urban drainage systems can only deal with the rainfall scale of small to medium rain and the extreme weather caused by climate change, the rainfall is increased, and urban waterlogging often occurs, so that the road traffic capacity is reduced and the traffic conditions are worsened, urban traffic is paralyzed, traffic jam and traffic accidents are caused, and the life and property safety of people is seriously harmed. In addition, the impermeable road surface reduces the humidity of the urban air, and accelerates the formation of the urban heat island effect. On the basis of this, researchers have proposed the concept of a sponge city, which means that the city has good "elasticity" in terms of adapting to environmental changes and coping with natural disasters caused by rainwater, and may also be referred to as a "hydro-elastic city". The international general term is "low impact development rainwater system construction", i.e. water absorption, water storage, water seepage and clean water during rain, and the stored water is "released" and utilized when needed.

There are the following problems:

1. the existing permeable and drainage road surface is integrally laid, the road surface is compacted to form a driving belt without a drainage function along with the prolonging of the service life of the road surface, and when urban rainfall is large, the inside of the road is easy to have a closed water storage area one by one, so that the water is accumulated on the road surface.
