以云南保(山)腾(冲)高速公路为例,开展中央绿化带大孔自压微灌技术研究及应用示范.首先提出了中央绿化带示范段的灌溉目标和系统设计,构建大孔微灌管的水力学模型并编制Matlab计算程序,对不同管材选择、管径大小、孔径大小以及孔距等要素进行试算,以判定灌溉系统设计方案是否满足设定的灌溉系统均匀度参数要求,最后对方案进行了实验验证.结果表明:通过变孔径大孔自压微灌技术,可在满足防堵塞性能的基础上,保证灌水均匀度,提高灌溉质量和灌溉保证率.

Technological research and application demonstration of large-hole gravity micro-irrigation in expressway central greenbelt were carried out on the basis of Bao-Teng (Baoshan-Tengchong) Expressway in Yunnan Province.First,irrigation goal and system design of demonstration part of the expressway central greenbelt were put forward; next hydraulic model and relevant Matlab program about large-hole micro-irrigation were set up to make a preliminary calculation of the type,diameter,distance and other factors of the pipe holes; then the whole design of the irrigation system was examined to check if it had met the designed irrigation uniformity demands and it was eventually verified by experiments.Results showed that:irrigation uniformity can be ensured with the technology of large-hole gravity micro-irrigation with variable hole diameters under the condition of block prevention,and thus the irrigation quality and efficiency can be improved.
