文章针对普通混凝土井管和过虑器(过滤井管)存在的成井深度浅、寿命短等问题,设计了基于钢筋预紧、采用无焊缝异形管箍的深水井新型井管;介绍了深水井新型井管原料选用、配比、钢骨结构及其新型井管的特点。实际应用表明:该深水井新型井管成井深度可达300~600 m,适合各种土质地层。 In this paper, aiming at the problems such as shallow well depth and short service life of common concrete well pipe and filter (tubular), a new type of well pipe based on preloading of steel bar and deepwater well without weld pipe was designed. Selection of new well tube raw materials, ratio, steel structure and the characteristics of its new well. The practical application shows that the well depth of the new well tube in this deep water well reaches 300-600 m, which is suitable for various soil formations.
