Abstract
The invention discloses a kind of Recoverable anchor rod device, it comprises bolt tube, the steel strand connector be connected in bolt tube, be arranged on the sleeve pipe in bolt tube and be hinged at flexible supporter between bolt tube and sleeve pipe, described steel strand connector is fixedly installed steel strand, described internal surface of sleeve pipe is provided with self-lock pin, and described bolt tube is provided with the draw-in groove corresponding with self-lock pin.The present invention steel strand and steel strand connector after anchoring task completes directly exit screw thread and effectively can realize recycling; It is umbrella that support chip struts firmly, after end slip casting terminates, can increase the friction bond stress between anchor pole and rock-soil layer, makes anchoring more firm, ensure that bonding strength and reliability.
Description
Technical field
The present invention relates to a kind of anchor rod device, especially a kind of Recoverable anchor rod device for geotechnical slope field of reinforcement.
Background technology
At present, in existing Base hole supporting technology, the foundation ditch temporary support structures of many use anchor poles is difficult to reclaim owing to building on the one hand, causes great waste of material; On the other hand, it is to the maintenance of stability of civil engineering, and especially in Jointed Rock Masses, the reinforcement effect of anchor pole is limited.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of economical and practical, breakout capacity is strong and steel strand and connector can realize effective anchor rod device reclaimed.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of Recoverable anchor rod device, it comprises bolt tube, the steel strand connector be connected in bolt tube, be arranged on the sleeve pipe in bolt tube and be hinged at flexible supporter between bolt tube and sleeve pipe, described steel strand connector is fixedly installed steel strand, described internal surface of sleeve pipe is provided with self-lock pin, and described bolt tube is provided with the draw-in groove corresponding with self-lock pin.
Further, described steel strand connector is provided with external thread wire mouth, and described bolt tube correspondence is provided with internal thread silk mouth.
Further, described bolt tube is provided with the first link slot and the first sliding tray, on described sleeve pipe with the first link slot, the first sliding tray is corresponding is provided with the second link slot, the second sliding tray.
Further, described supporter is hinged by two identical sheet metals and forms.
The beneficial effect adopting technique scheme to produce is: a kind of Recoverable anchor rod device of the present invention, wherein steel strand connector and bolt tube are threaded connection, and after anchoring task completes, steel strand and steel strand connector directly exit screw thread and effectively can realize recycling; Internal surface of sleeve pipe is provided with self-lock pin, and making supporter strut rear is firmly umbrella, after end slip casting terminates, can increase the friction bond stress between anchor pole and rock-soil layer, makes anchoring more firm, ensure that bonding strength and reliability.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
As shown in accompanying drawing 1-7, a kind of Recoverable anchor rod device, it comprises bolt tube 3, the steel strand connector 2 be connected in bolt tube 3, be arranged on the sleeve pipe 4 in bolt tube 3 and be hinged at flexible supporter 5 between bolt tube 3 and sleeve pipe 4, described steel strand connector 2 is fixedly installed steel strand 1, described sleeve pipe 4 inwall is provided with self-lock pin 6, described bolt tube 3 is provided with the draw-in groove 7 corresponding with self-lock pin 6, makes supporter 5 realize firm support; Steel strand connector 2 is provided with external thread wire mouth, and in bolt tube 3 one end, correspondence is provided with internal thread silk mouth, and after anchoring task completes, steel strand and steel strand connector directly exit screw thread and effectively can realize recycling; Bolt tube 3 is provided with the first sliding tray 3-1, the first link slot 3-2, and on sleeve pipe 4, correspondence is provided with the second sliding tray 4-1, the second link slot 4-2, to ensure that supporter 5 is freely stretched out and contraction.
The present invention uses step as follows:
(1) beat hole 8 to the projected depth that diameter is 20cm, the inclination angle of itself and horizontal plane is 10-20 degree;
(2) reamer is utilized in the end reaming of hole 8 to umbrella;
(3) end slip casting;
(4) prefabricated anchor pole is put into, strut the supporter 5 be hinged between sleeve pipe 4 and bolt tube 3, it is made to be umbrella, the length of supporter 5 two sheet metals is 20cm, arranging summit to the vertical distance on base is 15cm, and now self-lock pin 6 is locked in draw-in groove 7, makes prestressing force reach design load, object increases the friction bond stress between termination and rock-soil layer, makes anchoring become more firm;
(5), after temporary structure supporting terminates, steel strand are backed out and connector reclaims.
Reasonable in design of the present invention, steel strand 1 and steel strand connector 2 can effectively reclaim, and reduce cost, and anchoring section design, in umbrella, ensure that bonding strength and operating reliability.
The above embodiment is only the preferred embodiments of the present invention, and and the feasible enforcement of non-invention exhaustive.For persons skilled in the art, to any apparent change done by it under the prerequisite not deviating from the principle of the invention and spirit, all should be contemplated as falling with within claims of the present invention.
