可回收锚杆技术发展与展望

Development and prospect of removable anchor technology

可回收锚杆技术避免了锚杆主筋不回收带来的地下障碍物和侵权问题,近年来在基坑工程中得到快速发展和推广应用。回顾和总结可回收锚杆技术的应用背景以及国内外可回收锚杆技术、相关标准的发展过程,对可回收锚杆类型进行归纳分类,详细阐述当前常用的可回收锚杆构造及其回收机理,提出在可回收锚杆技术应用中需要重视的一些问题。最后针对可回收锚杆技术应用的现状,对其研究和发展方向给出建议。

Removable anchor technology,which has developed rapidly and been applied to foundation pit projects in recent years,may avoid those problems of underground obstacles and infringement associated with the non-removable main reinforcement.In this work,the application background of removable anchor technology and the development process of removable anchor technology and relevant standards at home and abroad were reviewed and summarized,the types of removable anchor were categorized,and the configuration and removable mechanism of removable anchor commonly used were elaborated,and then the issues deserving attention in the applications of removable anchor technology were put forward.Finally,based on the application status of removable anchor technology,some suggestions on its research and development direction were given.
