| 摘 要： | 针对当前高速公路中央绿化带人工水车灌溉存在的费用高、影响畅通,以及现有的滴灌技术用于中央绿化带中存在的难以解决的滴头堵塞问题,提出了利用大孔管自压微灌的中央绿化带灌溉思路;并以云南保腾高速公路某段中央绿化带为例,进行了变孔径大孔管自压微灌系统设计,通过水力学模型及MatLAB软件进行了包括初始水头、孔间距、孔径等计算以确定工程方案;最后应用中央绿化带实体模型,对设计灌溉方案的灌溉效果进行验证.研究结果表明,该方案能满足微灌技术要求,为中央绿化带植物生长提供用水需求. |

| Abstract: | A large-bore pipe self-pressure micro-irrigation method was put forward to solve some defects in expressway central greenbelt irrigation,such as high-cost,traffic jam with water tankers irrigation and congestion in drip irrigation system,which can scarcely ever be solved.Taking a segement of Yunan Baoteng expressway as an example,a variable aperture big hole pipe from the pressure of micro-irrigation system was designed,the initial water head,hole pitch and aperture were calculated with software MatLab to make sure the engineering program.Finally,the central green belts entity model was built up to prove the design of irrigation schemes irrigation effect.The results turned out that the program can meet the technical requirement of micro-irrigation,demand for the central green plant growth. |
