喷灌省水、增产,效益显著。世界各国发展很快。我国近年来,也有所发展,至1980年喷灌面积已达一千万亩以上。这对我国水源不足的地区,合理利用水资源找到了一条新的途径。本文所介绍的二原子自压喷灌工程,是以汤峪水库八里原干渠为水源,利用地形自然高差(1.6～1.8％)所形成的水头,通过管道进行喷灌的,能灌溉两千多亩耕地。设计管道系统静水内压力最高达8公斤/厘米~2。管网布设:在进水陡坡段铺设φ300毫
Sprinkling irrigation water, increase production, significant benefits. All countries in the world have developed rapidly. In recent years, China has also made some progress. By 1980, the amount of sprinkler irrigation reached more than 10 million mu. This has found a new way for the rational use of water resources in areas with insufficient water resources in China. The two-atom self-pressure irrigation irrigation project introduced in this paper is based on the original trunk canal of Tangli Reservoir, using the head formed by the natural topography (1.6~1.8%), and it is sprinkled through the pipeline. It can irrigate 2,000 mu of land. arable land. The pressure in the still water of the design piping system is up to 8 kg/cm~2. Pipeline layout: Laying φ300 millimetres in the steep slope of the inlet
