灌区低压管道输水灌溉技术

Water delivery irrigation technology by low pressure pipeline in irrigation area

灌区管道输水系统占地少，能减少灌溉水量的渗漏和蒸发损失，是农田灌溉实现节水、渠系输、配、灌水自动化的一条经济有效途径。该文针对灌区低压管道输水系统规划设计参数确定、管网布置、管材选择、附属设备选择等方面进行了概述。

Water delivery system by pipe in irrigation area covers a land less and can greatly reduce evaporation and infiltration loss. So this is economical and effective way saving water and accomplishing the automation of water delivery, distribution and irrigation in farm irrigation. The paper summaries the parameter determination, pipe network layout, pipe material and auxiliary equipment selection for planning and design of low pressure water delivery pipe system in irrigation area.
