水平孔管定位方法

Horizontal hole pipe orientation methods

结合工程概况,介绍了定位索布置方案,对索孔管固定过程的力学分析进行了阐述,通过探讨定位索的张力与索孔管悬垂度的关系对索孔管的定位方法进行了确定,并列举了具体的实例加以说明,可供同类工程参考。

Combined with the projects general situation, it introduces the laying out program of orientation cable, represents the mechanical analysis of the whole controlling process of cable hole pipe. It decides the orientation methods of cable hole pipe through discussing the relation between the tensile force of orientation cable and the overhang degree of cable hole pipe, and lists the specific examples to explanation, and it can gives reference to other projects.
