路缘石开口在道路排水系统中的应用

Curb Opening Applied in Road Drainage System

随着中国海绵城市的发展,生态型的道路排水系统正在逐步推广。在道路排水设计中,生物滞留设施日益得到广泛应用,而通过路缘石开口将路面雨水排入生物滞留设施是最为常见的做法。以厦门市海沧区某道路工程的排水设计为例,介绍路缘石开口形式,以及通过计算确定路缘石开口的设计间距、设计尺寸,并总结设计流速、汇水面积、集流时间等参数在路缘石开口设计中的影响。

With the development of China's sponge city,ecological road drainage system is gradually being promoted.In the design of road drainage,biological detention facilities are increasingly widely used,and through the curb opening to the pavement rainwater into the biological detention facilities is the most common practice.Taking the drainage design of a road project in Haicang District of Xiamen as an example,the curb opening types are introduced;the design distance & dimension of the curb opening are determined by calculation; and finally,the parameters influencing on the curb opening design are summarized such as design flow rate,catchment area and collecting time,etc.
