Research On Application And Popularization Of Permeable Pavement In Sponge City

In the process of urbanization in China,ecological problems have become increasingly prominent,frequent urban water logging indicates that the city's water cycle system needs to be improved.With the rise of sponge city construction boom,the city's ecological construction has been more and more attention,some foreign rainwater management and management concepts such as low impact development technology(LID),green infrastructure(GI),Sustainable urban drainage system(SUDS)after long-term application and development,has a good functional effect,can be used as an important reference for China's sponge city construction.In the face of urban pavement caused by the surface water,groundwater resources and the possible shortage of serious urban floods and other water ecological problems,need to take effective project management measures to solve.This paper proposes to improve the problem of urban pavement drainage through the effect of pavement drainage and flooding.Firstly,analyzed the effect of water permeation pavement in sponge city and the relationship between sponge city and pavement.Secondly,the cost analysis method is used to analyze the pervious pavement in sponge city: Through the quantitative analysis of the engineering costs and operating expenses of the pavement,the qualitative analysis of the social and environmental benefits such as maintaining the ecological balance of the soil,improving the city's acousto-optic pollution and alleviating the urban heat island effect,The importance of permeable pavement for sponge city construction;Through the permeable pavement planning,design,construction,testing and maintenance and other aspects of the construction of the relevant issues may be focused analysis,Strengthening of pervasive pavement technology application management,regulate the penetration of pavement in the sponge city in the construction and application;Finally,from the deepening of ecological construction concept,improve the policy and system,develop standards and norms,to speed up the construction of supporting industries,etc,put forward the sponge city pavement important promotion countermeasures.Through the analysis,it can be seen that the application of pervious pavement technology in sponge city construction not only has good pavement and drainage effect,which is of great significance to the ecological construction of sponge city.Expectation With the sponge city construction boom,will pavement and other rainwater management technology more applied to China's urban construction,and jointly promote the city's ecological civilization construction and sustainable development.
