管井出砂及滤网堵塞是管井报废的主要原因,要提高管井的使用寿命, 首先要在运用上按水源能力确定开采量。在此前提下,要严格执行科学的填砾工艺、确实保证填砾厚度、滤网选用耐腐蚀材料、加强滤管的防腐等,以求全面提高管井过水部分过水、滤水性能。 Tubing sand and filter plugging is the main reason for the tube well scrapped, to improve the service life of tube wells, we must first determine the amount of exploitation by the water source capacity. Under this premise, it is necessary to strictly enforce the scientific gravel-packing process, ensure the thickness of the gravel, filter selection of corrosion-resistant materials, and enhance the anti-corrosion of the filter pipe, in order to improve the over-water and drainage performance of the over-water pipe well.
