预应力混凝土管桩机械快速螺纹连接技术及其推广应用

Technology and application of the prestressed concrete pipe mechanical quick screw connection

目前众多建筑工程中的管桩连接均采用人工焊接,焊接质量不良引起的焊接问题占用了相当比例,尤其是抗拔桩质量更难保证,本文介绍了预应力混凝土管桩机械快速螺纹连接的构造、特点、施工安装方法及其在工程中的应用情况,这种新的连接方法具有施工工期短,不受气候环境和人为因素的影响,综合经济效益显著等特点。

Presently the joining of the tubular pile of the numerous construction engineering mostly adopted the manual welding,in which the bad welding quality often caused a lot of sealing problems especially the welding quality of the uplift pile.And the construction quality,installation method and engineering application of the quick threaded connection of the prestressed concrete tubular pile machinery was introduced in this article,which this kind of the new connection method had the short construction period and free from the climatic environment and influence of the human factor,and had the remarkable economy of integration and so on.
