喷灌工程区域管网分为主干管、干管、支管三级管道
因此本项目区满足喷灌设计风速要求
该灌区喷灌形式以固定式喷灌为主
沟窝灌区域沿主山梁布设干管
喷灌工程的水源利用现有的四级提灌工程作为本次工程规划的水源
灌区内需要灌溉的3—9月份平均风速为2m/s
At present, the irrigation area sprinkler irrigation is formed by the sprinkler fixed in place during watering primarily, auxiliary filled by the furrow, the water source of sprinkler irrigation project uses existing four levels splash the project to take this project plan
According to the geological terrain condition, the pipe network for sprinkler irrigation of this region divided into three levels of pipelines for the vital main pipeline ,the main pipeline, the laterals
The main pipeline moves towards the arrangement along the mountain ridge as far as possible, the laterals parallel arranges along the contour line, all the pipelines use the steel pipe which spread clearly and completely; The furrow irrigation region along the host mountain builds the main pipeline, using the hose to irrigation
