Design Of Permeable Bricks And Pavement Based On The Concept Of Sponge City

The large area of surface hardening in the city is one of the characteristics of urbanization.The impervious pavement changes the natural circulation properties of the soil,vegetation and infiltration layer,and accelerates the heat island effect and flood disaster and a series of negative problems.In recent years.Urban construction has been aware of the hazards of overheating,and gradually turned to a new,with environmental protection,ecological and water conservation functions of the ground laying-permeable pavement.This is not only a necessary measure for urban development,but also one of the important issues in the construction of sponge city,but the existing permeable brick can not fully meet the national standard,although with the initial permeable mode,but the long-term use will be due to insufficient strength Resulting in large-scale splitting,wear and tear a high degree of damage,and large-scale use of permeable brick cost is very high,greatly affected the permeable brick in the sponge city to promote the use.So this article on how to improve the use of permeable brick pavement as the focus of this design.In this paper,the use of pervious pavement system is analyzed,and some problems existing in the pavement pavement for hard ground treatment are found.The method of forming the permeable brick itself can not always be compared with that of hard pavement,Resulting in the use of tiles in the practical application will have a large area of fragmentation.Secondly,some of the use of structural permeable brick because of its gap is too large,will be used for a long time after the pore blockage,cleaning and maintenance is very difficult.These problems have greatly reduced the permeability of pervious pavement to the sponge city.This paper designed a combination of small brick impermeable high-strength hard material surrounded by small brick impermeable material,Point,arranged in the laying of the rules on the ground to solve the current hard pavement impermeable and permeable pavement strength is not enough,easy to plug and other issues.And according to this bifurcation principle designed a different pavement style,in the form of water pavement to solve a single style problem.The use of this bracketing brick design improves the strength of the permeable bricks,prolongs the service life,avoids the complexity of post-maintenance,also enriches the diversity of pavement,reduces the economic burden of urban construction,improves the tiles in the sponge Utilization in the city.
