我国水泥井管发展已有近30年的历史。自从钢筋砼井警(钢板(?)焊接接头)于1969年研制成功,1970年在中深井中使用以来,水泥井管的生产技术与使用范围推进了一大步。20年来,钢筋砼井管经历了3个阶段。70年代为发展农灌事业和工业生产的需要,大力开发地下水,机井建设处于大规模的发展时期。当时,为缓解钢材紧缺的矛盾,满足大规模机井建设的需要,非金属井管管料,尤其是钢筋砼井管的试验研究、生产与施工
The development of cement wells in China has been in the past 30 years. Since the development of reinforced concrete wells (steel welded joints) in 1969, and since its use in medium and deep wells in 1970, the production technology and scope of cement well pipes have taken a big step forward. For 20 years, reinforced concrete wells have undergone three stages. In the 1970s, in order to develop the needs of agricultural irrigation and industrial production, groundwater was vigorously developed, and well construction was in a period of large-scale development. At that time, in order to alleviate the inconsistency of steel shortages and meet the needs of large-scale well construction, non-metallic well pipe and tube materials, especially reinforced concrete pipes, were tested and researched, produced and constructed.
