摘要
结合丘陵地区灌区地形高低有起伏,灌面不规整,灌溉管网不易布置的特点,介绍了丘陵地区典型灌面管网总体布置方案及灌溉组划分方案,通过自下而上逐级推求管网管道流量及管道水头损失,得出灌溉管网等管径水头线坡降沿程递减曲线的变化规律,同时总结各级管道灌溉流量计算方法、管径拟定方法、管网水力计算方法及管道沿线水压力复核方法。
Combined with the characteristics of hilly irrigation area with undulating terrain,irregular irrigation surface and difficult layout of irrigation pipe network,this paper introduces the general layout scheme of typical irrigation surface pipe network and irrigation group division scheme in hilly area.Through the step-by-step calculation of pipe flow and pipe head loss in the pipe network from bottom to top,the variation law of slope decline curve of water head line with equal diameter in the irrigation pipe network is obtained.At the same time,the calculation methods of irrigation flow,pipe diameter,hydraulic calculation method of pipe network and review method of water pressure along the pipeline are summarized.
