利用灌水均匀度确定地下渗灌工程技术参数的试验研究

Using the Test of Uniformity Degree of Watering to Determine Technical Parameters of Subirrigation

针对上世纪90年代初山西运城市在大面积发展地下渗灌技术中所存在的问题,在夹马口灌区进行了渗水管的灌水均匀度试验。通过试验研究,确定了地下渗水管长不大于95 m、间距不大于1.2 m、渗水孔间距不大于0.6 m的适于当地实际的渗灌工程技术参数,为该市后期的渗灌补配套工程建设提供了必要的规划设计依据,为促进该项技术的健康发展发挥了重要作用。

Aimed at the existing technical problems in developing subirrigation on a large scale area in Yun cheng City in the early days of 1990s,the test of uniformity degree of watering through infiltration pipe was carried out in Jiamakou Irrigation District. Through test and research, the technical parameters of subirrigation suited to practical situation in situ are determined ：the length of subirrigation infiltration pipe must be less than 95m,the centre distance of pipe less than 1.2m and the centre distance of infiltration hole less than 0.6m. These parameters provide planning and design basis for the future construction of subirrigation project in this city and will take important effect to promote healthy development of this technique.
