Application Of Permeable Paving In Sponge City

With With the deepening of the sustainable development strategy,the new concept of“sponge city”has entered people's field of vision.Permeable paving technology is the most common and practical construction technology in the construction of a sponge city.Secondly,it is a sustainable construction technology.The permeable paving technology not only makes full use of the characteristics of water absorption,water holding,and water release,but also is an important manifestation of coordinated development of urbanization and environmental resources,namely natural accumulation and natural penetration.This paper mainly studies the phenomenon of the decline of permeation capacity,foundation settlement and surface cracking that often appear in pervious paving works.In this paper,the definition of pervious paving,the principles and types of pervious water,and the effects of various structural layers are analyzed.The effect of pervious paving type,aggregate grading,and admixture on permeability coefficient and compressive strength is determined through experiments.Analyze the problems that occur during actual construction.Use ANSYS software to establish a model to analyze the effects of soil quality,aggregate gradation,compaction density,surface material,and applied load on the foundation settlement.Through engineering examples,we summarized the design,management,construction management,post-testing and maintenance management,and quality acceptance management of the permeable paving project,as well as the promotion of permeable paving methods from the development of permeable paving at home and abroad.Through analysis,we can see that the application of permeable paving in the construction of sponge city not only has good paving and platooning.The water effect is of great significance for the ecological construction of sponge cities.With the upsurge of the construction of the sponge city,expect to see the water paving technology is more applied to the urban construction in China,and jointly promotes the construction of urban ecological civilization and sustainable development.
