Abstract
The utility model discloses a detachable anchorage device, which is improved based on ordinary straight-plane anchorage device. The detachable anchorage device comprises a supporting plate, an anchor ring and a clamping sheet. The clamping sheet is of a two-sheet type; the inner hole of the anchor ring is arranged as a straight hole; four threaded holes of M10 are evenly arranged at the periphery of the outer wall; the clamping sheet is of a conical shape; when the clamping sheet is put into the steel strand, a bolt is screwed into the anchor ring to abut against the clamping sheet, so as to make wedge effect artificially; the clamping sheet tightly locks the steel strand, to lead the tightly pull steel strand; when the tunnel does use the anchorage device any more, the bolt can be screwed out, the anchorage device can be detached, so as to realize recycle purpose.
Description
Affiliated technical field
The detachable ground tackle of this novel patent is because of rock-reinforcing cable bolting means, can recycling ground tackle and steel supporting plate, economize on resources the minimizing cost.Cable bolting is used to improve the stress state of rock mass as a kind of rock-reinforcing means, improves rock mass strength, and the distortion of control rock mass promotes the stable of rock mass, uses more and more widely in various geotechnical engineerings.Anchor cable is as effective digging roadway support mode, compare with other supporting means and to have into that lane speed is fast, labour intensity is low, improve the drift section utilization rate, simplify the termination service procedure of back production face, obviously improve operating environment and safety production condition, become the main support form of home and abroad colliery underworkings, obtained wideling popularize application.
Background technology
Anchor cable be fixed in by the outer end domatic, the other end is anchored at slide plane to pass the prestress wire of slope sliding face in the interior rock mass stability, directly on sliding surface, produce sliding resistance, increase antiskid frictional resistance, make structural plane be in impaction state, to improve the globality of slope rock mass, thereby fundamentally improve the mechanical property of rock mass, control the displacement of rock mass effectively, impel it stable, reach the purpose of regulation along layer, landslide and crag, danger stone.Main construction techniques comprises following technology: boring, anchor cable is installed, anchoring section slip casting, apeak pier, stretch-draw.Boring is the critical process of control duration in the anchor cable construction.For guaranteeing drilling efficiency and guaranteeing drilling quality, adopt the down-the-hole impact drill.During drill drilling, put neatly by the anchor cable design length required drilling rod of will holing, drilling rod uses up, and hole depth also puts in place just.Boring finishes, and water is rinsed the hole well, puts into resin anchoring agent then earlier, at the bottom of with steel strand the hole slowly being sent in the anchoring agent, the jumbolter chain is connected, start jumbolter with agitator, steel strand evenly stir the anchoring agent, and mixing time must reach the time of anchoring agent requirement.Last first-class steel supporting plate and ground tackle carry out stretch-draw after half an hour.The common ground tackle of facing directly belongs to strand tapered anchorage, is made up of supporting plate, anchor ring and intermediate plate, and intermediate plate is a two-piece type, heads straight for seam.Because anchor ring endoporus and intermediate plate are all made cone shape, ground tackle is under the wedge effect effect, and when steel strand were subjected to pulling force, ground tackle tightly pinned it, made steel strand draw tighter and tighter, thereby played the effect of anchoring.
Summary of the invention
Can not dismantle the deficiency that can't recycle in order to overcome common ground tackle, the utility model provides a kind of detachable ground tackle, and this ground tackle not only has locking function, and for convenience detach, can repeatedly reuse.
The technical scheme that its technical problem that solves the utility model adopts is: the anchor ring endoporus is made straight hole, around outer wall, evenly stamp the screwed hole of 4 M10, when packing steel strand into, screw in the anchor ring with bolt, prop up intermediate plate, the people is for making wedge effect, and intermediate plate tightly pins steel strand, makes steel strand draw tighter and tighter, and when the tunnel does not re-use, then can screw out bolt, because the anchor ring endoporus is a straight hole, so can easily pull down intermediate plate.The concrete structure shape is seen Figure of description 1.
The beneficial effects of the utility model are, have detachable function, can repeatedly reuse, and moulding is simple, makes things convenient for processing and manufacturing.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the vertical section constructional drawing of detachable ground tackle embodiment, 1. intermediate plates among the figure, 2. anchor ring, 3. bolt.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the vertical section front view of detachable ground tackle anchor ring, and figure is marked with whole physical dimensions.
Fig. 4 is the left view of Fig. 3.
The specific embodiment
In Fig. 1, steel strand pass anchor ring (2), clamp in the anchor ring endoporus of packing into by two intermediate plates (1), steel strand are carried out stretch-draw, the bolt (3) of 4 M10 is screwed in four uniform screwed holes of anchor ring outer wall, make bolt prop up intermediate plate, the people is for making wedge effect, owing to be subjected to tension, intermediate plate tightly pins steel strand, make steel strand draw tighter and tighter, thereby play the effect of anchoring.
When the tunnel does not re-use, then can screw out bolt, because the anchor ring endoporus is a straight hole,, take off anchor ring so can easily pull down intermediate plate, reclaim firm supporting plate.
Claims (1)
1. detachable ground tackle, by anchor ring, intermediate plate, bolt is formed, and it is characterized in that: the anchor ring endoporus is made straight hole, evenly stamps the screwed hole of 4 M10 around outer wall, during use, screws in bolt and props up intermediate plate, during recovery, screws out the Bolt dismantling ground tackle.
