海绵城市在市政道路给排水设计中的应用

The Application of Sponge City in Water Supply and Drainage Design of Municipal Road

分析了海绵城市道路给排水设计原则和基本思路,从排水体制的选择、管网平面布局和纵向交叉方式、透水性路面结构、优化路拱横坡、设置下凹式绿化带等方面探讨了海绵城市理念在道路给排水设计阶段具体应用形式,研究成果可为提高城市道路给排水能力提供相应的理论指导。

This paper analyzes the principles and basic ideas of water supply and drainage design for road of sponge city,and discusses the application form of sponge city concept in road water supply and drainage design stage from the aspects of drainage system selection,pipe network layout and vertical cross mode,permeable pavement structure,optimization of road arch cross slope,and setting concave green belt design.The research results can provide reference for optimizing the water supply and drainage efficiency of urban roads Theoretical guidance.
