摘要
轻型井是采用轻质、薄壁管材,优化的滤水结构,合理的成井工艺建成的一种小口径管井。具有取水效率高,单井出水量大,施工简便,造价低廉,管理方便等优点。针对宁夏银北灌区目前井灌工程效率低下的问题,通过抽水试验,经过理论分析,计算得出了灌区井灌系统的最优出水量、最佳扬程,从而提高了机井灌溉效率。
Light well is a sort of well with small caliber, built with light and thin material, choosing optimize leaching structure and logical techniques. It has lots of strong points as higher of pump efficiency,larger of flow, simpler of construct, lower of cost, and easier of management, and so on. Aiming at the lower efficiency of irrigation with well in Yinbei irrigation districts in Ningxia province at present. Based on pumping experiment, the best lift quantity and the head of bump of well system in Yinbei irrigation districts were calculated. So the efficiency of well irrigation was raised.
