机井是主要灌溉设施之一,对农业生产起着极其重要的作用,但由于机井施工时忽视成井工艺等原因,致使一些机井质量较差。有的机井则是因为管理使用不善,缺乏维修保养等原因,而产生涌砂、淤积、坍塌等问题,机井的出水量呈逐年衰减趋势,文章重点从成井工艺技术和机井管护方面对机井淤积原因和防治对策进行阐述。 One of the main irrigation facilities is the machine shaft, which plays an extremely important role in agricultural production. However, due to the neglect of the well-forming process and other reasons during the construction of the shaft, some of the machine shafts are of poor quality. Some wells are due to poor management, lack of maintenance and other reasons, resulting in the surge of sand, siltation, collapse and other issues, shaft efflux showed a declining trend year by year, the article focuses on the well technology and mechanized well management of siltation wells Reasons and prevention and control measures to elaborate.
