灌区明渠输水与PCCP管道输水方案比较

Comparison of open channel water conveyance and PCCP pipe water conveyance

本文根据该自流灌区的地形、地貌和现有灌溉条件等特点,从多个方面分析比较了明渠输水和PCCP管道输水这两种方案的优缺点,从而得知后者具有安全性强、易实施、运行管理方便、长期运行费用低、占地面积小及灌溉方式灵活等优点,故建议该工程采用PCCP管道输水方案。最后,本文还建议在类似工程中,特别是在地形起伏较大的灌区内,可以推广运用管道输水,以提高我国农田灌溉水的利用率。

The paper compares the merit and the shortcoming of open channel water conveyance and the PCCP pipe water conveyance according to the topography and the geomorphy,existed irrigation condition in the irrigation area by gravity,proposes that the PCCP pipe water conveyance scheme is adopted in this project.The PCCP pipe is even suitable in the irrigation area of rolling topography.
