平原地区雨水管道设计坡度的选择

Selection of Design Gradient for Rainwater Pipeline in Plain Region

平原地区由于地势平坦,排水管道往往无地形高差可以利用,造成下游管道埋深过大。该文以工程实例来说明平原地区的雨水管道设计坡度选择问题,为雨水管道设计提供了新的经验。

As the terrain in plain region is flat,the topographical height difference for the drainage pipeline cannot be utilized so as to cause the pipelines in the lower reaches are buried too deeply.The article explains the selection problems of the design gradient for the rainwater pipelines in the plain regions by the engineering examples,which provide the new experience for the design of the rainwater pipelines.
