Description
Technical field
This utility model relates to well work Roadway Support Technology field, forward Counterboring apparatus at the bottom of especially a kind of anchor hole hole, tunnel.
Background technology
In the construction of existing well work roadway bolting support technology, the work progress of anchor pole is generally: first by the drill bit matched with anchor rod body diameter, the bolthole that diameter is unified is set in rockbolt installation position, the Anchor Agent meeting " three footpaths mate " principle is put into at the bottom of hole in bolthole, anchor pole is pushed in anchor hole, anchor pole is driven to rotate until Anchor Agent stirs and anchor pole is made a gift to someone at the bottom of hole in hole with rig, after Anchor Agent solidifies, within the scope of certain length at the bottom of anchor hole hole, finally constitute " hole wall country rock-Anchor Agent-body of rod " this anchor structure.
Existing bolt support technology, owing to the diameter of anchor hole is unified, when running into broken, loose and soft surrounding rock, cohesive force between hole wall country rock and Anchor Agent is less, under the effect of pressure from surrounding rock, it is easy to yield failure, causes fastening invalidation, do not reach the purpose suppressing deformation of the surrounding rock in tunnel.
Summary of the invention
Destroying to solve in existing anchorage technology the little adhesive surface caused between Anchor Agent and hole wall of cohesive force between hole wall country rock and Anchor Agent, the problem ultimately causing anchor structure unstability, this utility model provides at the bottom of a kind of anchor hole hole, tunnel forward Counterboring apparatus.
For realizing this technical purpose, the technical solution adopted in the utility model is: forward Counterboring apparatus at the bottom of a kind of anchor hole hole, tunnel, including blade mounting seat, mobile square bar, blade, blade jacking block, movable sleeving, support link, link supports seat, reaming drilling rod and reaming foot piece, described blade mounting seat is connected with mobile square bar seam, described blade jacking block is arranged on the both sides of movable sleeving, described movable sleeving is connected with link supports seat front end, described mobile square bar is arranged in movable sleeving, the tail end of described blade is hinged with blade mounting seat, the front end of described blade is hinged with the front end of support link, the tail end of described support link is hinged with link supports seat, described link supports seat is connected with reaming drilling rod, the rear end of described reaming drilling rod is fixed with reaming foot piece.
Further, it is tough that the outline of described blade is provided with cutter, and the front end of described blade is provided with withdrawing chamfering, and the leading inside of described blade is provided with intermediate groove.
Further, described mobile square bar and movable sleeving can be movable relatively, and relative movement distance ranges for 0～60mm.
Further, described blade can be movable relatively with mobile square bar, and the angular range of described blade and mobile square bar side is 0～42 °.
Advantage of the present utility model and having the beneficial effects that: this utility model can reduce construction anchor pole in soft, breaking surrounding rock, the probability of anchor structure unstability is caused because the cohesive force between Anchor Agent and boring country rock is little, increase Bolt System tension pull out force in the country rock soft, broken, integrity is poor, control suspension roof support class deformation of the surrounding rock in tunnel, destruction are significant.
