居住小区给水管道设计流量计算方法

Calculation Method of Design Flow for Water Supply Pipelinein Residential Quarter

目的推导出居住小区给水管道设计流量计算公式,为实际工程中的居住小区给水管道设计流量的计算提供参考.方法从市政给水管道设计流量的计算公式与室内给水管道设计流量的计算公式的差异考虑,以室内给水管道的设计流量计算公式为上限,以市政给水管道的设计流量计算公式为下限,使居住小区给水管道的设计流量与市政及室内给水管道设计流量有一个恰当的衔接.结果推导出了居住小区中Ⅰ、Ⅱ、Ⅲ类住宅在不同给水当量数情况下的给水管道设计流量的计算公式,使管段设计流量的计算更符合实际.结论完全采用市政或室内给水管道的设计流量公式,计算居住小区给水管道的设计流量是不合理的,采用衔接法来计算与实际较为相符.

This paper is to attain a calculating formula of design flow of water supply pipeline in residential quarter,which could be a reference to the actual engineering of calculating problem of design flow of water supply pipeline in residential quarter.Consider the flow deference between the municipal transition flow and the indoor flow,assume calculating formula of design flow in indoor water supply pipeline as upper limit and calculating formula of design flow in municipal water supply pipeline as lower limit,...
