A kind of perforation major part slip casting constant-resistance anchor pole
Technical field
The present invention relates to a kind of perforation major part slip casting constant-resistance anchor pole in the supporting equipment.
Background technology
The bolting with wire mesh mode is widely used in mine, and anchor rete cord combined supporting mode substitutes existing shed shoring mode gradually, and the relaxation zone theory, that the anchor net forms the built-up arch force structure is ripe; But shift to an earlier date damaged supporting failure phenomenon and occur often along with adopting after dark increase and the anchoring of soft rock problem termination point of anchor rod Bolted Rock Masses.The existing stressed increase of bolting with wire mesh anchor pole the stressed conical funnel structure of Bolted Rock Masses broken invalid problem and anchor pole can occur and diminish and reduce the built-up arch strength problem.The existing bolting with wire mesh of application circumstances of adopting dark heavily stressed bolting with wire mesh, soft rock bolting with wire mesh and fractured coal and rock bolting with wire mesh greatly is difficult to adapt to, develop a kind of anchor pole that is suitable for the use of above-mentioned particular surroundings, this anchor pole should have increases anchored force, increase the anchoring area, strengthen the characteristics that built-up arch intensity, high-pressure slip-casting and constant-resistance are out of shape; When being subjected to bump, can constant-resistance be out of shape pressure release simultaneously, for mine safety production provides safeguard.
Summary of the invention
At the defective of existing anchor-net Shoring Technique, the purpose of this invention is to provide a kind of product of perforation major part slip casting constant-resistance anchor pole.
A kind of perforation major part slip casting constant-resistance anchor pole technical scheme feature provided by the invention is:

The product of perforation major part slip casting constant-resistance anchor pole of the present invention has solved existing common bolt low problem of supporting intensity under the complex geological condition of heavily stressed, soft rock and fragmented rock body.Existing common bolt the built-up arch intensity decline that diminishes of solid area coal and rock broken invalid of grapnel or stressed conical funnel can occur during little stressed increases of the anchoring of anchor pole normal pressure, anchoring area under above-mentioned geological conditions; Impact force action anchor pole when anchor pole can not be out of shape causes the supporting global failure, and the whole detection device safety of anchor pole afterbody installation simultaneously reclaims difficulty.Develop a kind of anchor pole of use of suitable mine particular surroundings, this anchor pole should have increases anchored force, increase the anchoring area, strengthen the characteristics that built-up arch intensity, high-pressure slip-casting and constant-resistance are out of shape; Can constant-resistance be out of shape pressure release simultaneously when being subjected to bump, the checkout gear that afterbody is installed is the recyclable structure of lengthening safety.Its advantage is as follows:
1, perforation major part slip casting constant-resistance anchor pole forms the perforation crack by the blasting and perforating device at termination point of anchor rod, in termination fractured coal and rock (soft rock), form the major part anchoring rod by O type sealing of hole powder stick device and high-pressure slip-casting device again, make the conical funnel force structure of original small area of contact become the large-area halfpace force structure in big termination, increase built-up arch thickness and improve the supporting bulk strength;
2, said apparatus can be used with common bolt and reach major part high-pressure slip-casting anchor pole effect, and simultaneously to regulate O type sealing of hole powder stick be that blowing agent can the shutoff armature boring to O type sealing of hole powder stick device, plays isolated gas, water blockoff and prevents the effect of weathering;
3, the effective shock absorbing power of the constant-resistance anamorphic attachment for cinemascope of perforation major part slip casting constant-resistance anchor pole guarantees the integrality and the supporting intensity constant-resistance of buffering distortion back supporting;
4, the lengthening checkout gear of perforation major part slip casting constant-resistance anchor pole can extend on anchor (rope) bar tailing screw flight or screw thread anchor cable pressure lobe, the instrumentation cover is installed to lengthening detect stressing conditions on the connecting rod, original anchor nut locking anchor pole behind the removal process dismounting lengthening connecting rod nut, stop that collection apparatus process anchor pole lost efficacy, the stressed big nut of crossing of anchor pole ejects and hurts sb.'s feelings and instrumentation damages problem such as can't change, this device can be used the effect that reaches anchor pole safety detection, recovery and replacing with common anchor (rope) bar simultaneously;
5, the prolongation anchor cable device of perforation major part slip casting constant-resistance anchor pole can install the prolongation anchor cable additional in constant-resistance anamorphic attachment for cinemascope termination, forms constant-resistance distortion anchor cable, improves anchor rod anchored scope and supporting bulk strength.
