摘要
利用高新技术研制的新型贴砾滤水管具有较高的强度和特点 ,它可广泛应用于水井工程和旧井处理工程中 ,不仅能提高生产效率、降低成本 ,而且还可彻底治理涌砂问题。
The new type gravel strainer developed by high-new technique has more high strength and outstanding character. So it can be extensively used in the course of the water well project and the old well recondition project,at the same time,and not only raise working efficiency and reduce costs of production but also harness thoroughly the inrush of sand.
