Research On Application Technology Of Permeable Pavement

In recent years,with the acceleration of urbanization,the surface of modern cities is being covered by concrete and other water-resisting materials.Urban ecological problems such as urban waterlogging and heat-island effect are becoming more and more serious.In 2015,Jinan was selected in the “National Sponge City Construction Pilot Area”.In order to achieve the sponge city functional requirements of “Seepage,stagnation,storage,purification,utilization and drainage ",permeable pavement becomes an effective means of controlling rainwater runoff,and it has been widely used in “Sponge City” construction.This thesis is based on the project of sponge city construction in Jinan.The work of this thesis mainly includes four parts.Firstly,the development status of permeable pavement at home and abroad is studied,and the origin and development process of permeable pavement are discussed,as well as the technological development route of developed countries abroad.Secondly,this party introduces the permeable pavement from three aspects including permeable pavement materials,structural design and construction technology,and summarizes the material selection criteria,structural design process and different construction technology of permeable brick,permeable cement concrete and permeable asphalt mixture,also presented the key points of construction.Thirdly,this party discusses the application of permeable pavement in urban landscape,and puts forward the design principle,material selection and combination application scheme of permeable pavement in urban landscape application.Fourthly,on the basis of the research on the application technology of permeable pavement,taking the projects "Xing Long Shan region Reconstruction" and "PPP Project Xing ji River Basin" in the construction of "Sponge City" in Jinan as examples,this paper introduces the application of permeable pavement combined with urban landscape design in the construction of sponge city in Jinan in detail,and has carried out the construction of the project.Many new technologies,new processes,new equipment and new materials have been used in the project.
