In the prior art, in order to avoid construction waste formed by waste anchor rods after construction is finished, trouble is brought to newly built underground buildings or structures outside a foundation pit. Therefore, the anchor rod is of a recyclable design.
However, the recoverable anchor rod in the prior art has the technical problem of weak anchoring capability.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of providing a recoverable anchor rod with enhanced anchoring capability,
in order to solve the technical problem, the utility model discloses a technical scheme does:
the recoverable anchor rod with the enhanced anchoring capability comprises an anchor rod, wherein the bottom of the anchor rod is in threaded connection with an anchoring piece; the anchoring piece comprises an anchoring rod, a sleeve and an anchoring foot; the sleeve is movably sleeved on the anchoring rod, and a plurality of anchoring feet are movably hinged on the same radial plane of the outer side wall of the anchoring rod; the anchoring feet are positioned below the sleeve and are respectively connected to the sleeve through connecting pieces; a sleeve is movably sleeved outside the anchor rod; the sleeve is pushed downwards to enable the anchoring foot to be unfolded, and the whole anchoring foot is in an umbrella shape after being unfolded.
Furthermore, 3-6 anchoring feet are arranged.
Furthermore, the lower top of anchor pole is equipped with the taper cylinder, just the more sharp one end of taper cylinder deviates from sleeve direction one side.
Further, the connecting piece is an elastic component.
Furthermore, the connecting piece is respectively and movably hinged with the sleeve and the anchoring foot.
The utility model has the advantages that:
when the utility model is used, firstly, all the anchoring feet are contracted and lean against the anchoring rod, after the anchor rod and the anchoring piece are put down into the drilled hole, the anchoring feet are completely propped open by pushing the sleeve downwards, and the anchoring feet are integrally umbrella-shaped after being propped open; after the anchoring feet are completely propped open, pouring concrete pulp into the hole so as to anchor the anchoring piece in the drilled hole; after the pouring is finished, the anchor rod can be recovered from the anchoring rod through reversely rotating the anchor rod. The utility model discloses an anchor assembly of special structural design can effectively strengthen the anchoring ability.
