摘要
通过雨量分析、网状雨水管道系统布置、连通管道水力分析三方面,对网状雨水管道系统的可行性进行理论分析。笔者认为,在某些特殊的工况下,特别是指在同一区域中排水区域划分很不均匀的雨水排水系统,把不同干管系统的中下游雨水管道通过连通管道连接成网状,有利于雨水径流的分配、疏通及排放,也可以减少下游雨水井发生雍水溢流的危险。
This paper analyzes the feasibility of the networked rainwater pipeline system through three aspects:rainfall analysis,mesh rainwater pipeline system layout and connected pipeline hydraulic analysis.Under some special cases,especially for the cases that the drainage area is unevenly divided,the middle and lower rainwater pipes of different main pipe systems are connected into a network through the connecting pipes,which is beneficial to the rainwater runoff,distribution and discharge,and can also reduce the risk of flooding in downstream rainwater wells.
