塑料软管灌溉近年来在我国北方地区应用发展很快,但由于时间较短,从理论到实践都存在一些问题。有些方面如物理力学性状、水力性能指标、允许工作压力、以及管材的适宜规格等方面也缺乏资料。根据试验,本文从塑料软管耐水压力及其影响因素、塑料软管的应力分析、塑料软管的弹性变性与允许工作压力和软管水力参数和管材选配四个方面提出了分析研究结果,供各地在推广塑料软管灌溉技术时参考选用。
In recent years, the application of plastic tube irrigation has developed rapidly in the northern part of our country, but due to the short time, there are some problems from theory to practice. Some aspects, such as physical and mechanical properties, hydraulic performance indicators, to allow work pressure, as well as pipe specifications and other aspects of the lack of information. According to the experiment, this paper puts forward the analysis and research results from four aspects: water pressure resistance of plastic hoses and its influencing factors, stress analysis of plastic hoses, elastic degeneration and allowable working pressure of plastic hoses and hydraulic parameters of hoses and pipe matching. For around the promotion of plastic hose irrigation technology reference selection.
