摘　　要：平湖市是全国第一个实现灌溉地下管道化的县(市).低压输水管道建成,有效的节约了灌溉成本,同时大大提高了灌溉效率.但经过几年,铺设的农田地下管网不少都出现了老化现象,管道内壁淤积严重,灌溉用水无法顺畅地输送,降低了灌溉效率.为有效解决淤积问题,经过较长时间的研究和多次现场试验,不断改良通渠技术,改装通渠设备,地下灌溉管道疏通新技术终于获得成功.Pinghu City is the first county to realize channelization sub-irrigation.Low-pressure water pipe greatly improved irrigation efficiency with less costs.But after a few years,the aging farmland sub-pipe resulted in serious deposition in conduit internal wall,which reduced the irrigation efficiency because of rough convey.The new dredging technology for sub-irrigation pipe is introduced in the paper based on a long-term study and numerous on-site tests,realizing an effective drainage with improved canal equipment.
