随着全球气候变化异常,旱灾频发且持续时间较长,给农作物的生长带来严重影响,甚至造成部分粮食作物和经济作物绝收。今年来,农田水利基本建设投入逐年加大,新打农用灌溉机井的数量不断增加,病坏井数量也在逐年增加,究其原因,主要是长期以来形成的重建轻管造成的。文章结合实际就病井成因、病井修复方法进行了论述,希冀为类似工程的建设与管理有所借鉴。
With the global climate change anomalies, frequent and prolonged droughts have a serious impact on the growth of crops and have even resulted in the partial harvest of some food crops and cash crops. This year, the capital construction of irrigation and water conservancy projects has been increasing year by year. The number of newly-opened agricultural irrigation machines and shafts has also been on the increase. The number of sick and well wells has also increased year by year. The reason for this is mainly the long-term reconstruction of light pipe. The article discusses the causes of the sick wells and the methods of repairing the sick wells, hoping to draw lessons from the construction and management of similar projects.
