Description
Technical field
The utility model relates to the anchor pole of a kind of tunnel anchoring, particularly a kind of wing formula anchor pole that can carry out the expansion of anchor pole end under existing construction method.
Background technology
In engineer applied, in order to improve the anchored force of single anchor rod, the normal end reaming method that adopts expands anchor pole end, then carries out slip casting and draws anchor.Can make the stressed enhancing of hole reaming of anchor rod like this, anchoring effect increases, but shortcoming to cause the increment of anchoring section collateral resistance less, and load effect is relatively weak.Again because the anchored force of anchor pole provides primarily of the collateral resistance of anchoring section, and the stability in this region and reliability directly determine the safe coefficient of whole engineering, so the body of rod and anchoring body stripping accident happen occasionally, engineering is lost seriously.Because the collateral resistance of anchoring reaming section is not equally distributed, but form peak value in its front end, progressively terminad reduces.So the Perfected process improving end side resistance carries out body of rod expansion in anchoring section end, but the requirement of direct expansion to armature boring of rod end is larger, construction method can not meet, so provide a kind of wing formula anchor pole that can carry out the expansion of anchor pole end under existing construction method just to become very necessary.
Summary of the invention
The problem of anchor pole end expansion cannot be solved in order to solve existing construction method, the utility model provides a kind of wing formula anchor pole, this wing formula anchor pole can reach the object of anchoring section end expansion while adapting to general-purpose construction method, and supporting effect is good, and project benefit is remarkable.
The utility model solves the technical scheme that its technical problem adopts: wing formula anchor pole, comprising: anchorage nut, washer plate, anchor rod body, retaining pin, push wing steel pipe, positioning bar, wing, the wing opened, reinforcing bar annulus, wing bending ring, supporting station post; This wing formula anchor pole has a columniform anchor rod body, the wing of the plate shape that can expand, reinforcing bar annulus and wing bending ring is provided with in the bottom of anchor rod body, supporting station post is provided with between wing bending ring and anchor rod body, supporting station post and anchor rod body weld together, wing bending ring one end is welded on wing root, and in the hole of the reinforcing bar annulus of spiral-lock between two supporting station posts, above reinforcing bar annulus, slip cap is equipped with push wing steel pipe, is 120 degree is uniformly distributed and is welded with reinforcing bar positioning bar on the surface of push wing steel pipe; On anchor rod body above push wing steel pipe, be welded with retaining pin, its effect is that restriction push wing steel pipe can only open by unidirectional promotion wing; Above retaining pin washer plate and anchorage nut be housed.
One end of described wing bending ring is carried out secondary bending and is formed serpentine, one end of " S " bending together with wing bottom welding, the other end of wing bending ring, in order to limit the opening angle of wing, the maximum opening angle of wing is 90 degree; The upper end of wing is overlapped on push wing steel pipe, and wing is separated by positioning bar interval.
In the process of laying anchor rod body, anchor rod body can be navigated to drill center by the positioning bar on push wing steel pipe.Anchor rod body is slightly pulled back after laying and putting in place immediately, push wing steel pipe forms relative motion forward under the acting in conjunction of pulling force and sidewall resistance, promotes wing and opens, wing in the process of opening with sidewall contact, form larger tension force, until open up into the maximum opening angle 90 degree of restriction.Carry out slip casting after wing opens, treat that slurry intensity carries out stretch-draw anchor after reaching 80% of design strength, locking anchor pole.
The beneficial effects of the utility model are: this wing formula anchor pole can reach the object of anchoring section end expansion meeting existing execution conditions while, and structure is simple, and easy to use, supporting effect is good, and project benefit is remarkable.
