古东灌区农发骨干渠系改造工程设计中,对部分流经村庄的渠道采用玻璃钢管输水方案代替对现有渠道的防渗,不仅提高了干渠水的利用率,还防止水质受到污染,方便管理、减少土地平整工作量。同时,充分利用水源水头压力,有利于喷灌等先进节水技术推广应用。 In the design of the agricultural drainage trunk canal system reconstruction project in the ancient East Irrigation Area, part of the channels that flowed through the villages were replaced by glass fiber reinforced plastic pipelines to prevent seepage from the existing channels, which not only improved the utilization rate of water in the main channels but also prevented the pollution of water quality, Facilitate management and reduce land formation workload. At the same time, make full use of water head pressure, is conducive to irrigation and other advanced water saving technology promotion and application.
