Self-expanding type expansion body recoverable anchor rod
The invention relates to a self-expanding type expansion body recoverable anchor rod, and belongs to the technical field of anchor rods. The self-expanding type expanding body recoverable anchor rod comprises a driving-in anchor head and a rotating main rod, a groove is formed in the driving-in anchor head, and a tenon embedded with the groove is arranged at the front end of the rotating main rod; a plurality of pressure-bearing tables are fixedly arranged on a rod body of the rotating main rod, an arch-shaped expansion body is arranged between every two adjacent pressure-bearing tables, a threaded hole is formed in the upper end of each arch-shaped expansion body, a through hole is formed in the lower end of each arch-shaped expansion body, a threaded section corresponding to the threaded hole is arranged on the rod body of the rotating main rod, and a positioning block is fixedly arranged below each threaded section; a through hole is formed in the rear end of the rotating main rod, and a screwing handle rod is arranged in the through hole in a penetrating mode. The construction technology is simple, recycling is convenient, the problems that most recyclable anchor rods are difficult to recycle, the construction technology is complex and the like are effectively solved, the construction efficiency is improved, and environmental pollution is reduced.
本发明涉及一种自扩式扩体可回收锚杆，属于锚杆技术领域。所述自扩式扩体可回收锚杆包括击入锚头和旋转主杆，所述击入锚头上开设有凹槽，所述旋转主杆前端设有与所述凹槽相嵌合的榫头；所述旋转主杆的杆身上固设有多个承压台，两相邻设置的承压台之间设有一个弓形扩体，所述弓形扩体上端开设有螺纹孔，下端开设有通孔，所述旋转主杆的杆身上对应所述螺纹孔设置有螺纹段，所述螺纹段下方固设有定位块；所述旋转主杆后端开设有贯穿孔，所述贯穿孔内部穿设有旋拧把杆。本发明施工工艺简单、回收便捷，有效地解决了大多可回收锚杆回收困难和施工工艺复杂等问题，提高了施工的效率，减少了环境污染。
