摘要
地埋式自动伸缩喷灌设备作为一种新型高效节水灌溉设备具有较为显著的优势.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、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指导.
Abstract
The buried automatic telescopic sprinkler system as an new efficient water-saving irrigation equipment has significant advantages,which has reached the international advanced level.Taking a buried automatic telescopic sprinkler system of alfalfa planting demonstration area in the Ningxia water-saving and efficient agriculture science and technology park as an example,summed up the construction technology and the considerations for the system from the excavation site survey,construction design and lofting,earthwork excavation,pipeline installation and pressure testing,nozzle installation and backfill the trench,manholes and drain well construction,the filter system installation,water power system construction and others aspects.It can provided guidance for construction and renovation the sprinkler system or efficient water-saving irrigation projects.
