城市雨水管道設計,一般都是先計算雨水逕流量,后再是逕流量进行管道水力計算,得出断面設計尺寸。在这二步計算过程中,虽可充分利用图表解之。以达簡化手續。然而在雨水管綱系統初步規划阶段,仅要求确定排水流向和断面概略数值。若仍按这种方法計算,确实感到有点繁杂。为了提高工作效率,簡化計算手續,我們設制了一張城市雨水管道設計計算諾謨图,經过实际的应用,这种型
The design of urban stormwater pipelines is generally based on the calculation of stormwater runoff, followed by runoff calculation of the pipeline hydraulics to obtain the section design dimensions. In this two-step calculation process, the graphs can be fully utilized. To achieve simplification. However, in the preliminary planning stage of the rainwater pipe system, only the drainage flow direction and the profile values are required to be determined. If it is still calculated in this way, it does feel a bit complicated. In order to increase work efficiency and simplify calculation procedures, we have designed a city rainwater pipe design and calculation chart. After actual application, this type
