Description
Technical field
The utility model is related to a kind of suitable for Deep Mine soft and broken surrounding rocks and the self-drilling type in the larger tunnel of deformation
Two-stage, which allows, presses recyclable grouted anchor bar, belongs to mine grouting support technical field.
Background technology
As pit mining gradually extends to deep, under high-ground stress effect, the deformation characteristic of rock mass it occur frequently that compared with
Big change, ROCK MASS JOINT, crack are opened, and a large amount of crackles are occurred, are that mine support brings many difficulties, are enclosed to better control over
Rock, people carry out slip casting frequently with hollow grouting anchor its support reinforcement mode, to country rock and fill up crack, form overall country rock, control
Roadway deformation processed.But common grouted anchor bar is disposable, and substantial amounts of anchor pole is embedded in underground and causes the neighbouring area underground space
Exploitation is difficult, and support cost is high, greatly causes the waste of resource；Simultaneously grouted anchor bar in stress, usually due to be denatured compared with
There is tensile failure greatly, it is impossible to function well as anchorage effect；The cement grout of high-pressure slip-casting usually can cross conference because of pressure
Sprayed from injected hole, not only cause the waste of material, but also there is potential safety hazard.
Utility model content
For above-mentioned technical problem, the utility model provides a kind of safe and reliable, self-drilling type double bracket of recyclable recycling
Disk two-stage allows the recyclable grouted anchor bar of pressure, it by anchor pole from brills, anchoring, slip casting, current limliting, allow and press and be recovered in one, greatly
The utilization rate for improving anchor pole, improve the bearing capacity of roadway surrounding rock, it is ensured that the stabilization in tunnel.
To achieve the above object, the technical scheme that the utility model solves that its technical problem used is：
A kind of self-drilling type two-stage allows the recyclable grouted anchor bar of pressure, including hollow lead to starch the body of rod, the hollow slip casting body of rod, steel bushing
Cylinder, spiral wing, drill bit, straight-bar, spring, hemisphere, pallet A, spring by depressor, pallet B, allow pressure pipe and nut, be characterised by：
The hollow slurry body of rod of leading is connected by steel bushing internal thread with the hollow slip casting body of rod, and a series of spiral shells are evenly arranged on the hollow slip casting body of rod
Revolve wing, interlaced arrangement causes injected hole between adjoining spiral wing, spring installed between pallet A and pallet B by depressor, pallet B and
Installed between nut and allow pressure pipe, the hollow slip casting body of rod is put at pallet A a spring, spring and semicircle on a straight-bar, straight-bar
Ball is connected.
The rod body material is fiberglass, and body of rod outer surface is threaded, and steel bushing sets in through hole, through hole and set and bar
The identical internal thread of external surface screw thread, the body of rod is connected by steel bushing.
Spiral wing is provided with the hollow slip casting body of rod excircle, spiral wing pitch is 20~24mm, in adjoining spiral
A series of injected holes consistent with the spiral wing hand of spiral of interlaced arrangement between wing, increase and the adhesion of bolthole.
Spring is installed by depressor between the pallet A and pallet B, allows and presses 0~80mm of scope, is pacified between pallet B and nut
If allowing pressure pipe, allow and press 0~30mm of scope.
Described nut is to lead the supporting spherical nut of the slurry body of rod with hollow.
Compared with existing anchor pole, the beneficial effects of the utility model are embodied in：By brill, anchoring, slip casting, the limit certainly of anchor pole
Flow, allow and press and be recovered in one；The body of rod uses glass steel material, and spark will not be produced during drilling, to tunnel safety construction extremely
Favorably, it is adapted to high methane concentration range, also reduces reinforcing bar and produce brought energy resource consumption and environmental pollution；Slip casting safely may be used
Lean on, realizing effectively can prevent slurries from flowing out after the completion of unidirectional grout, slurry injection, prevent slurries splash from causing security incident；
The bond area of anchor bar body and injecting paste material is added compared with the common body of rod, anchor force is improved, reinforcing bar usage amount has been saved；
With allowing pressure to act on, meet country rock initial stage large deformation and adjoining rock stability after small deformation, reduce the damage of anchor pole；Anchoring terminates
Afterwards, the slurry body of rod (1) is led by rotary hollow and partially recycled recycling can be achieved, greatly save roadway support cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1. hollow lead the injected hole of 5. drill bit of the slurry 4. spiral wing of hollow 3. steel bushing of the slip casting body of rod of the body of rod 2. 6.
7. the springs of 8. pallet B of pallet A 9. allow the spherical nut of 13. straight-bar of pressure pipe 11. semi-round ball, 12. spring 14. by depressor 10.
