农村供水工程树枝状配水管网水力计算简法

采用“最高用水量法”对农村供水工程中的树枝状配水管网进行水力计算 ,简化了计算程序。此法曾应用于日本国无偿援助“贵州农村饮水供应改善项目”的 30 0多座农村水厂的设计和技术审批。应用表明 ,用“最高用水量法”进行水力计算所建的农村水厂配水管网运行效果与设计相符 ,能有效地控制和把握建设农村水厂的技术经济指标 ,是农村树枝状供水管网水力计算的简捷方法。

Simple Method of Hydraulic Computation for Dendriform WaterAllocation Pipe Net of Water Supply Works in the Rural Area

In this paper,a method of maximum water consuming amount is adopted to make hydraulic calculation for dendriform water allocation pipe net of water supply works in the rural area and simplify the computation procedure.The method was applied in the design as well as technical examination and approval of more than 300 rural waterworks belonging to a project of rural drinkable water supply and improvement in Guizhou which was assisted gratuitously by the Japanese Government.The operational effect of rural water allocation pipe net computated hydraulically by the method of maximum water consuming amount is in accordance with design requirement.This method has proved to be effective in controlling and mastering some technical and economic indices of rural waterworks.
