Design Practice Of Permeable Pavement Based On Sponge City

Rigid pavement is widely used in the construction of urban landscape in China,which cause the damage of original natural hydro logical cycle and the reducing of the city's adaptability to rainwater,then lead to the destruction such as urban water logging and water imbalance.The “Sponge City” concept is proposed to use permeable pavement technology to solve the problem of the easy water accumulation on the watertight road surface,to improve road comport and safety.In this study,the design and practice of Sponge City permeable pavement is the main direction,taking Dong xin kai he design project in Changchun as an example,construct the urban drainage and water storage circulation system with the technology of permeable pavement.Create a rich space collage visual effect with the use of specific chroma to graphic,change the laying direction,beautify the design brick type,and diversify the specifications.Combine humanized pavement pattern according to the functional requirements of different sites.This technology research will lead the city construction out of the mistake of rigid pavement.It does help to maintain ecological balance,to protect the natural environment and to create a beautiful homeland.
