摘要
简述了锚杆技术的发展过程,从测量定位、下钻成孔、制作锚索及安放锚索等方面,阐述了囊袋式扩体锚杆支护施工技术的操作要点,指出该技术能与多种施工辅助工法相结合,从而提高锚固体系的承载和变形性能。
The paper briefly illustrates the development process of anchor rod technology,describes operation points of bag-style expansion anchor rod support construction technology from aspects of measurement orientation,bottom drilling hole forming,prefabricating anchor cable and setting anchor cable,and finally points out that: combining the above-mentioned technology with various construction aiding method can improve the bearing and deformation performance of the anchoring system.
