Abstract
The utility model discloses a novel hollow grouting anchor bolt comprising a hollow bar, a nut, a tray, a check valve, a grout stopper, a lock hoop, grout outlets and a round steel bar. The tray is sleeved to one end of the hollow bar and is fastened through the nut. The lock hoop is fastened on a body of the hollow bar. The hollow bar is further provided with the grout outlets. The round steel bar is welded at the other end of the hollow bar. The novel hollow grouting anchor bolt is operated in a full-length anchor mode, the anchor bolt is stressed more reasonably, post-mounting maintenance labor is reduced greatly, the anchor bolt is end-anchored with resin anchoring agent and can function in well anchoring immediately, and the potential safety hazards caused by the fact that the common grouting anchor bolt has no supporting capacity during grout solidification can be eliminated.
Description
Technical field
The utility model relates to the anchor pole field, especially relates to a kind of novel hollow grouting anchor.
Background technology
At present, common bolt can't be realized full length fastening, common grouted anchor bar because of the cement solidification overlong time, the anchoring support effect can't in time be provided, end anchor mounting means and the common hollow grouting anchor of common bolt are united two into one, after novel hollow grouting anchor uses resin anchoring agent to adopt the mode of end anchor to install, this moment, supporting effect was the same with traditional regular screw threads steel anchor rod, solved the problem of supporting safety; Follow-up anchor pole is carried out slip casting (but cement injection and chemical pulp), the effect that reaches the anchor pole full length fastening and reinforce the anchoring rock stratum, and also unified slip casting can be simplified down-hole supporting construction operation, improve slip casting efficient.
The utility model content
In order to overcome the defective of above-mentioned prior art, the utility model provides a kind of can play the novel hollow grouting anchor of anchoring effect preferably immediately.
The utility model is realized by following scheme, a kind of novel hollow grouting anchor, it is made up of hollow lever, nut, pallet, non retern valve, stop grouting plug, locking clip, slurry outlet and round steel, be with described pallet on one end of described hollow lever, tighten up by described nut, the body of rod of described hollow lever has tightened described locking clip, also is provided with described slurry outlet on the described hollow lever, and the other end of described hollow lever is welded with described round steel.
The utlity model has following beneficial effect in sum: the utility model anchor pole adopts the working method of full length fastening, anchor pole is stressed more reasonable, can significantly reduce the maintenance workload after the installation, when installing, uses anchor pole resin anchoring agent end anchor, can play anchoring effect preferably immediately, eliminate the common grouted anchor bar potential safety hazard that anchor pole non-support ability is brought in the slurries solidification process, in a word, can significantly improve the supporting security performance, reduce back anchor pole maintenance workload is installed.
