摘要
As a new efficient water-saving irrigation equipment, the buried automatic telescopic sprinkler system has reached the international advanced level and has significant advantages. Based on the buried automatic telescopic sprinkler system constructed the alfalfa planting demonstration area in Ningxia water-saving and effi- cient agriculture science and technology park, the construction technology and the matters needing attention were summarized and concluded from the following as- pects： excavation site survey, construction scheme design, site lofting and earth ex- cavation, pipeline installation and pressure testing, nozzle installation and pipe canal backfilling, investigation well and drain well construction, head filter system installa- tion, water power system construction, which provided guidance for construction and renovation of the sprinkler system and efficient water-saving irrigation projects.
地埋式自动伸缩喷灌设备作为一种达到国际领先水平的新型高效节水灌溉设备具有较为显著地优势,笔者以宁夏旱作节水高效农业科技园区内建设的地埋式自动伸缩喷灌苜蓿种植示范区为例,从现场勘测、施工方案设计、现场放线与土方开挖、管道铺设安装与压力测试、喷头安装与管沟回填、检查井与泄水井建设、首部过滤系统安装、水源动力系统建设等10个方面总结归纳了该系统的施工技术及其注意事项,为现有喷灌系统新建与改建及田间高效节水灌溉工程的建设提供给指导。
