为了解决路面的雨水处理问题,美国环境保护厅进行了关于渗透性路面的研究。以往修筑路面,基本是聚集雨水并设置使雨水加快流速的设施。但这种方法使降雨和径流间隔的迟滞时间缩短,导致最大流量和流速增大,所需的排水管道的口径相应增大。
In order to solve the problem of rainwater treatment on pavement, the United States Environmental Protection Agency conducted a study on permeable pavement. In the past, pavement construction basically consisted of gathering rainwater and setting facilities to speed up rainwater flow. However, this method reduces the lag time between rainfall and runoff intervals, resulting in an increase in maximum flow rate and flow rate and a corresponding increase in the diameter of the drain pipe.
