Abstract
The utility model discloses a kind of anchor cable improving anchored force, comprise anchor cable, lockset and supporting plate, it is characterized in that: in distance anchor cable, 300 ~ 400mm position, anchor termination arranges iron wire stirring bar, in distance anchor cable, the position of anchor termination 1400mm ~ 1600mm is provided with rubber baffle ring.The utility model structure is simple, cost of manufacture is low, easy to use, do not change working procedure and do not affect efficiency of construction prerequisite under, effectively can improve the anchored force of anchor cable.
Description
Technical field
The utility model relates to the anchor cable in tunnel and mine working supporting and stabilization works.
Background technology
The advantage that cable bolting has that anchorage depth is large, intensity is high, can apply not available for the bolt supports such as larger pretightning force is indispensable important Enhanced support means in tunnel and mine working roof timbering and stabilization works.
Along with the increase of the pit mining degree of depth, what correspond is that geological structure increases, roadway surrounding rock loose crushing, and the stress of primary rock and tectonic stress constantly raise, and in corresponding mining process, surrouding rock stress intensity is more outstanding.Present the rock mass of hard rock deformation-failure character at superficial part, be converted into high stressed soft rock after entering deep, the poor stability of rock mass, the fracture area of roadway surrounding rock and plastic zone scope greatly, therefore require also more and more higher to the anchored force of anchor cable.But due to the complexity of down-hole geological conditions, add the factors such as construction technology, in construction anchor cable hole process, sometimes inevitably cause eyelet aperture excessive, mine down-hole tunnel cable bolting mostly is end anchorage or the extensible bolting simultaneously, and the resin-bonded mastic in resin anchoring agent has certain mobility before solidifying, therefore anchor cable is in agitating resin Anchor Agent process, if there is no retention device in hole, Anchor Agent will trickle downwards, cause Anchor Agent closely knit not tight, its result will cause Anchor Agent to reduce the bond stress of anchor cable and the bonding force between Anchor Agent and hole wall.Anchorage cable anchoring power is Anchor Agent to the general name of the bond stress of anchor cable and the adhesion stress between Anchor Agent and hole wall, and therefore the anchored force of Anchor Agent to the reduction of the bond stress of anchor cable and the adhesion stress between Anchor Agent and hole wall in fact namely anchor cable reduces.
Summary of the invention
The utility model is the weak point for avoiding existing for above-mentioned prior art, provides the anchor cable of the improved anchored force that a kind of structure is simple, cost of manufacture is low, easy to use, practical.
The utility model is that technical solution problem adopts following technical scheme:
The anchor cable that the utility model can improve anchored force comprises anchor cable, lockset and supporting plate; Design feature of the present utility model is: in distance anchor cable, 300 ~ 400mm position, anchor termination arranges iron wire stirring bar, and in distance anchor cable, the position of anchor termination 1400mm ~ 1600mm is provided with rubber baffle ring.
The design feature that the utility model can improve the anchor cable of anchored force is also: described iron wire stirring bar is employing one iron leg silk, and the two ends of iron wire stirring are fixed in anchor cable, and the outside that the stage casing of iron wire is retained in anchor cable forms stirring bar.
Compared with the prior art, the utility model beneficial effect is embodied in:
The utility model has that structure is simple, cost of manufacture is low, easy to use, iron wire stirring bar and rubber baffle ring can be arranged in advance on ground on anchor cable and be transported to underground construction scene again, do not change working procedure and do not affect efficiency of construction prerequisite under, effectively raise the anchored force of anchor cable, therefore will inevitably obtain good supporting effect.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Number in the figure: 1 iron wire stirring bar, 2 rubber baffle rings, 3 supporting plates, 4 locksets, 5 anchor cables;
Detailed description of the invention
See Fig. 1, the anchor cable that can improve anchored force in the present embodiment comprises the anchor cable 5, lockset 4 and the supporting plate 3 that arrange routinely, in the present embodiment, in distance anchor cable, 300 ~ 400mm position, anchor termination arranges iron wire stirring bar 1, and in distance anchor cable, the position of anchor termination 1400mm ~ 1600mm is provided with rubber baffle ring 2.
In concrete enforcement, iron wire stirring bar 1 is employing one iron leg silk, and the two ends of iron wire stirring are fixed in anchor cable 5, and the outside that the stage casing of iron wire is retained in anchor cable 5 forms stirring bar.
As shown in Figure 1, iron wire stirring bar 1 makes as follows: oppositely outwarded winding by termination by anchor cable steel strand, first in distance anchor cable, anchor termination is about 400mm position and inserts the iron wire that a diameter is about 2mm, then anchor cable steel hinge line is forward screwed and anchor termination in distance anchor cable, another termination of the iron wire of insertion is about 300mm position and pull out and tighten, the anchor cable steel hinge line finally remainder oppositely outwarded winding all forward screws and restores to the original state, by this way iron wire is arranged in the both sides of anchor cable steel hinge line, form two stirring bars on similar anchor cable steel hinge line, its effect is agitating resin Anchor Agent, curing compound in resin anchoring agent and resin-bonded mastic are fully mixed, anchor cable is avoided to produce " gloves " phenomenon.
As shown in Figure 1, in the present embodiment, rubber baffle ring 2 is arranged on and is about 1500mm position apart from anchor termination in anchor cable, rubber stop ring length is about 60mm, the internal diameter of rubber baffle ring is slightly less than the diameter of anchor cable 5, the external diameter of rubber baffle ring is less than bore diameter about 3mm, utilize the high resiliency of the reversible deformation of rubber, guarantee that rubber baffle ring can be enclosed within anchor cable closely, trickle downwards to stop anchor cable Anchor Agent in agitating resin Anchor Agent process, thus improve the compactness of Anchor Agent in anchor cable boring, improve anchoring effect, realize the utility model object.
Installation process:
The first step, according to the anchor cable construction respective anchors bore dia of different-diameter specification and the anchor cable eyelet of the degree of depth.
Second step, puts into anchor hole by Anchor Agent, and by the anchor cable that the present embodiment provides, Anchor Agent is slowly sent into eyelet.
3rd step, with agitator, anchor cable and jumbolter output shaft are coupled together, start jumbolter to advance while stirring, by iron wire stirring bar agitating resin Anchor Agent, curing compound in resin anchoring agent and resin-bonded mastic are fully mixed, utilize rubber stop loop resistance to stop Anchor Agent to trickle downwards, improve the compactness of Anchor Agent in anchor cable boring, after anchor cable to be sent into and to be reached mixing time that Anchor Agent product specifies at the bottom of hole by jumbolter, rig is stopped to rotate but the rig that do not fall, wait for that resin anchoring agent falls rig after solidifying again, unload stirring connector, complete the anchoring of anchor cable,
4th step, installs anchor rope supporting plate 3 and lockset 4, then stretch-draw anchor, so far, completes with a kind of installation improving the anchor cable of anchorage cable anchoring power apparatus.
