格栅式消能池应用于山地城市排水系统

山地城市的地形坡度较大,排水管道系统的上、下端落差大,因而需设置大量的跌水、消能构筑物,为此,在城市排水管道工程设计中引入了在水利工程上常用的格栅式消能池工艺,并介绍了格栅式消能池的工艺构造、消能机理及设计计算方法。

Application of Grid Type Energy Dissipator in Sewerage System of Mountainous City

For the heavy slope gradient of landform in mountainous city, large numbers of energy dissipating structure must be designed in sewerage system to adapt the large fall between upper and lower sections. The grid type energy dissipator process, commonly used in water conservancy project, was adopted in the design of sewerage system. Its technological configuration, energy dissipating mechanism, and calculation method were summarized.
