Description
Technical field
The utility model is related to a kind of grouted anchor bar more particularly to a kind of slip casting anchors for preventing anchor pole from coming off from drilling
Bar.
Background technology
Anchor pole plays the maintenance of stability of civil engineering as one of main support form of underground engineering and rock slope
Important function, especially in Jointed Rock Masses, anchor pole is fairly obvious to the reinforcement effect of rock mass.The coal mine in China at present
The principal mode of roadway support is still the forms such as bolt-spary supports, bolting with wire mesh and anchor net unit support, and anchor pole is wherein
Effect it is particularly significant, grouted anchor bar becomes apparent the more surrounding rock supporting effect in crack, since support time is long or encloses
The reasons such as rock stress variation can all have an impact the anchorage effect of anchor pole, and anchor pole is made to deform or even be slid from drilling,
To the even staff of the equipment in tunnel, all there is security risks.
Invention content
In view of the above-mentioned problems, the utility model provides a kind of falling-proof type supplementary classification grouted anchor bar, can both strengthen
Anchor pole prevents anchor pole from coming off and can assist slip casting, realize the purpose of classification slip casting to the prestressing force of country rock.It is above-mentioned in order to realize
Function, technical solution provided by the utility model are：
A kind of falling-proof type supplementary classification grouted anchor bar, it includes：Grouting port, nut, Pressure-bearing pads, pedestal, stop grouting plug,
Inner tube, outer tube, outer slip casting slot, interior injected hole, rotation axis, anti-back pawl, rivet, anchoring end, friction taps, wherein：Anchor pole by
Grouting port, nut, Pressure-bearing pads, pedestal, stop grouting plug, outer tube, anchoring end are sequentially connected with composition；
A kind of falling-proof type supplementary classification grouted anchor bar of the utility model, wherein：Outer tube wall is dispersed with outer slip casting slot；
A kind of falling-proof type supplementary classification grouted anchor bar of the utility model, wherein：Outer tube sleeve inner tube；
A kind of falling-proof type supplementary classification grouted anchor bar of the utility model, wherein：Inner tubal wall is dispersed with interior injected hole, rotation
Axis, rivet, anti-back pawl；
A kind of falling-proof type supplementary classification grouted anchor bar of the utility model, wherein：Anti-back pawl one end is turned by rotation axis connection
Moving axis is fixed on inner tubal wall by rivet, and rotation axis is located at interior injected hole close to the side of anchoring end；
A kind of falling-proof type supplementary classification grouted anchor bar of the utility model, wherein：The anti-back pawl other end is friction taps.
Compared with prior art, the beneficial effects of the utility model are：
A kind of falling-proof type supplementary classification grouted anchor bar of the utility model improves the pretightning force of anchor pole and right using anti-back pawl
The frictional force of drill hole inner wall, prevents anchor pole from coming off from drilling to greatest extent, meanwhile, anti-back pawl is using unidirectional design, Yi Jin
Difficulty is moved back；In addition to this, the ring section that anti-back pawl is formed after opening can divide slip casting section in slip casting, realize classification slip casting,
Slip casting effect is enable to be promoted.

Specific embodiment
The utility model is described further below：
With reference to Fig. 1：A kind of falling-proof type supplementary classification grouted anchor bar：1- grouting ports, 2- nuts, 3- Pressure-bearing pads, 4- platforms
Seat, the outer slip casting slot of 5- stop grouting plugs, 6- inner tubes, 7- outer tubes, 8-, injected hole in 9-, 10- rotation axis, 11- anti-backs pawl, 12- rivets,
13- anchors end.
Specific embodiment is：Using rock drill or roof bolting equipment on country rock drilling, falling-proof type is assisted
Classification grouted anchor bar anticreep pawl friction taps are close to anchor pole outer tube outer wall, and anchor pole then is squeezed into drilling；Anchoring end touches
Resistance is formed after country rock, resist foot of hole country rock and with anchor pole inner tube formed support shaft, outer tube external pressure effect under after
It is continuous inwardly to promote, apply horizontal thrust to anti-back pawl rotation axis position using outer slip casting slot, anti-back pawl is unfolded, anti-back pawl rubs
The rock contact of end and drill hole inner wall is wiped, resistance is generated and fixes anchor pole；Finally by grouting port to anchor rod anchored country rock
Interior slip casting, by anti-back claw type into annular surface play the role of dividing slip casting region, supplementary classification slip casting, slip casting is completed using stopping
Slurry plug closing hell, assembles pedestal, Pressure-bearing pads, nut in bolt grouting mouth one end successively.It is auxiliary to complete a kind of falling-proof type
Help classification grouted anchor bar installation process.
