Pavement Runoff Control Technology of Spongy Urban Roads

为提高城市道路路面径流控制效果,基于低影响开发(LID)雨水系统原理,探究海绵城市道路路面径流控制技术。首先,分析城市道路径流雨水的汇流与转输过程,确立城市道路低影响开发雨水系统典型流程;其次,厘清分流制与合流制径流污染物总量计算参数,阐明低影响开发雨水系统的径流污染物控制机理;最后,分别阐明透水人行道铺装、下沉式绿化带、生物滞留、雨水弃流等道路径流控制的工程技术,为制定海绵城市道路路面径流控制方案提供依据。

In order to improve urban road runoff control effect,based on the LID rainwater system principle,the paper explores the road runoff control technology of sponge city. Firstly,this paper analyzes the confluence and transfer process of rainwater in urban road runoff,and establishes the typical flow flow of urban road with low impact on the development of rainwater system. Secondly,to clarify the calculation parameters of total runoff pollutants in shunt and confluence systems,to clarify the control mechanism of runoff pollutants that have low impact on rainwater development systems; Finally,the engineering techniques of road runoff control,such as paving,sinking green belt,biological detention and rainwater abandonment,are expounded respectively,which provide the basis for the design of road runoff control schemes for sponge city roads.
