Triple sleeve type recoverable anchor rod and anchoring method
The invention discloses a triple sleeve type recoverable anchor rod and an anchoring method. The triple sleeve type recoverable anchor rod comprises an outer pipe, a middle pipe and a long-strip-shaped locking inner core. The lower end of the outer pipe is closed, the upper end of the outer pipe is open, and multiple first through holes are formed in the side wall of the outer pipe at intervals. The middle pipe can be inserted into the outer pipe, and a plurality of anchoring parts are mounted in the middle pipe; the locking inner core can be inserted into the middle pipe; when the middle pipe is inserted into the outer pipe, the anchoring parts of the middle pipe are all located in the outer pipe. When the locking inner core is inserted into the middle pipe, the locking inner core can extrude the anchoring parts, so that one end of each anchoring part extends out of the outer pipe through the corresponding first through hole; and when the locking inner core is pulled out of the middle pipe, the anchoring parts which are not supported by the locking inner core are all retracted into the outer pipe, so that the anchor rod can be recycled and reused.
本发明公开了一种三重套管式可回收锚杆及锚固方法，包括外管、中间管和呈长条状的锁固内芯；外管的下端封闭，上端敞开，外管的侧壁上间隔开设有多个第一通孔；中间管能够插设在外管中，中间管中安装有多个锚固件；锁固内芯能够插设在中间管中；当中间管插设在外管中时，中间管的锚固件均位于外管中；当锁固内芯插设在中间管中时，锁固内芯能够挤压锚固件，使每个锚固件的一端通过对应的第一通孔伸出外管；当锁固内芯拔出中间管时，失去锁固内芯支撑的锚固件均缩回外管中，所以提供了一种能够回收和重复使用的锚杆。
