Y村灌区节水配套改造工程设计

摘要

Y村灌区是运城市一座多级提水引黄灌溉工程，也是山西省重点中型灌区之一。灌区泵站提水流量偏小，骨干渠道输水能力偏低，部分骨干渠道也需要轮灌运行，致使灌区效益得不到充分发挥。为此，本文对Y村灌区节水配套改造工程进行设计。该工程建设内容：（1）一级输水渠加固改造961m，设计流量为4.18m3/s，断面直径2.4m；二级输水渠加固改造476m，设计流量为4.18m3/s，断面直径2.4m；三级总干渠改造2.58km，设计流量为3.68m3/s，断面直径2.4m。（2）四级站拆除重建。工程实施后，可提高灌区骨干工程输水提水能力，使农作物可与适时浇灌，确保农作物的增产、稳产。
