Abstract
The utility model discloses a kind of recoverable anchor pole, comprise the externally threaded interior bar of band and tapped supporting body, the externally threaded interior bar of described band cooperatively interacts with tapped supporting body and is connected, rust preventive coating is provided with outside described interior bar, on the lateral wall of described supporting body, cover has PVC disrance sleeve, also comprises for by interior rod locking backing plate on the carrier and nut.In recoverable anchor pole of the present utility model, pole length can reach 3 ~ 12m, anchoring ability can reach 100 ~ 300kN, be far longer than length and the anchoring ability of existing anchor pole, in addition, the utility model recoverable anchor pole is provided with rust preventive coating outside interior bar, on supporting body lateral wall, cover has PVC disrance sleeve, therefore the anti-corrosion capability of anchor pole is substantially increased, after support engineering terminates, the interior bar of the utility model anchor pole can separate from supporting body, thus interior bar can be carried out recovery and again utilize.
Description
Technical field
The utility model relates to a kind of recoverable anchor pole.
Background technology
Along with the continuous expansion of construction scale of projects, the extensive application of anchor pole is that the national economic development has played important function, but due to the technological deficiency of conventional anchor pole, after support engineering terminates, a large amount of anchor poles is embedded in underground, not only cause the waste of material, and permanent pollution can be caused to the underground space.Many places once burying anchor pole underground will be faced with secondary development, and the existence of anchor pole will become the obstacle again developed, and while bringing difficulty, also considerably increase construction cost to the exploitation of successive projects.In addition, existing rock-bolt length is generally 1.5m ~ 3.0m, and anchored force is generally 30 ~ 100kN, and existing anchor pole also exists anchoring ability difference, antiseptic power is weak and the rate of recovery is low problem.Therefore, a kind of anti-corrosion capability is strong, anchoring effect good and the exploitation of callable anchor pole is necessary.
Utility model content
Utility model object: technical problem to be solved in the utility model is to provide that a kind of anti-corrosion capability is strong, anchoring effect good and callable anchor pole.
For solving the problems of the technologies described above, the technological means that the utility model adopts is:
A kind of recoverable anchor pole, comprise the externally threaded interior bar of band and tapped supporting body, the externally threaded interior bar of described band cooperatively interacts with tapped supporting body and is connected, rust preventive coating is provided with outside described interior bar, on the lateral wall of described supporting body, cover has PVC disrance sleeve, also comprises for by interior rod locking backing plate on the carrier and nut.
Further preferably, described interior bar is bar in reinforcing bar.
Further preferably, the length of described interior bar is 3 ~ 12m.
Beneficial effect: compared to prior art, in recoverable anchor pole of the present utility model, pole length can reach 3 ~ 12m, anchoring ability can reach 100 ~ 300kN, be far longer than length and the anchoring ability of existing anchor pole, in addition, the utility model recoverable anchor pole is provided with rust preventive coating outside interior bar, on supporting body lateral wall, cover has PVC disrance sleeve, therefore the anti-corrosion capability of anchor pole is substantially increased, after support engineering terminates, the interior bar of the utility model anchor pole can separate from supporting body, thus interior bar carried out recovery and again utilize, so not only efficiently solve the pollution problem of the underground space, and also a saving cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model recoverable anchor pole;
Fig. 2 is the using state figure of the utility model recoverable anchor pole.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, technology contents of the present utility model is described further.
As shown in Figure 1 and 2, recoverable anchor pole of the present utility model, comprise bar 1 in the externally threaded interior bar 1(of band and be provided with external screw thread with supporting body 2 place of cooperatively interacting) and tapped supporting body 2(supporting body 2 be internal thread pipe box), be with externally threaded interior bar 1 to cooperatively interact with tapped supporting body 2 to be connected, rust preventive coating 3 is provided with outside interior bar 1, the length of interior bar is 3 ~ 12m, on the lateral wall of supporting body 2, cover has disrance sleeve 4, disrance sleeve 4 is PVC disrance sleeve, PVC disrance sleeve can strengthen the anti-corrosion capability of anchor pole, recoverable anchor pole of the present utility model also comprises for interior bar 1 being locked at further backing plate 5 on supporting body 2 and nut 6.
After sloping surface arrangement completes, according to the aperture of designing requirement, length and inclination angle, auger is adopted to carry out creeping into perforate, after perforate, the recoverable anchor pole assembled is pushed to desired depth, then between rock-soil layer 7 and the supporting body 2 of anchor pole, slip casting makes anchor pole be fixed in hole, for filling with layer of slurry 8 between the supporting body 2 of rock-soil layer 7 and anchor pole, after slurry sclerosis, cover backing plate 5, by tensioning equipment fastening nut 6, the interior bar 1 of anchor pole is made to produce elastic deformation, supporting body 2 produces prestressing force, further interior bar 1 be locked on supporting body 2 to reach and reinforce the effect of anchor pole further, after support engineering terminates, release prestressing force, relies on manual operations oppositely to return bar 1 in stubborn reinforcing bar, interior bar 1 is spun off from supporting body 2, just interior bar 1 can be reclaimed.Anchor pole and ground are effectively combined by cementitious matter fixed form by the utility model recoverable anchor pole.
In recoverable anchor pole of the present utility model, bar 1 length can reach 3 ~ 12m, anchoring ability can reach 100 ~ 300kN, be far longer than length and the anchoring ability of existing anchor pole, in addition, the utility model recoverable anchor pole is provided with rust preventive coating 3 outside interior bar 1, on supporting body 2 lateral wall, cover has PVC disrance sleeve 4, therefore the anti-corrosion capability of anchor pole is substantially increased, after support engineering terminates, the interior bar 1 of the utility model anchor pole can separate from supporting body 2, thus interior bar 1 carried out recovery and again utilize, so not only efficiently solve the pollution problem of the underground space, and also a saving cost.
