Abstract

Abstract: In view of the complex conditions of large drop ratio and long pipeline of Chongqing Zhong-Wan highway green belt drip irrigation project, an iterative solution mathematical model was established based on Darcy-Weisbach formula, and the indoor hydraulic experiment was arranged to obtain the measured parameters to verify. In view of the influence of the design parameters of the drip pipe network, including the length of the pipe, the distance between the drippers and the slope ratio on the outflow uniformity, it is pointed out that the appropriate combination of the initial water head and the distance between the drippers can meet the requirements of the outflow uniformity of the drip irrigation system under certain slope ratio, pipe length and other boundary conditions.

Key words: drip irrigation system, highway green belt, Darcy-Weisbach equation, outflow uniformity

摘要： 针对重庆忠万高速绿化带滴灌工程的比降大、管道长的复杂条件，基于Darcy-Weisbach公式建立了迭代求解数学模型，并布置室内水力学实验获得实测参数来验证。针对滴管管网设计参数，包括管长、滴头间距、坡比等对出流均匀度的影响，指出在一定的坡比、管长等边界条件下，适当的初始水头、滴头间距参数组合可满足滴灌系统的出流均匀度要求。
