Abstract
The utility model relates to steel strands of a line holding type reclaimable anchoring bolt, which is a prestressed rib without adhesion. A cylinder-shaped loading body is sheathed with the anchoring end heat of the anchoring bolt, and a circular loading plate which is connected with a cone-shaped guide device is connected with the lower end face of the loading body; a cylinder-shaped fixing device which is used for fixing the steel strands is arranged at the increasing position of the radical number of the steel strands, a middle loading plate is connected with the lower end face of the fixing device, after each steel strand presses through a threading hole, and the end part is tight grasped by a grasping line. The utility model has the characteristics that the steel strands can be recovered, the underground public hazards can not be result in, the cost is lower and the construction period is shorter than used as the inner supporting, the stress is better than that of a stretch-draw type anchoring bolt, and the anchoring section is shortened. The utility model is suitable for the engineering which needs to demount the anchoring bolt of a supporting and protecting structure.
Description
The utility model relates to the prestressing force bank protection anchor pole that a kind of construction work bank protection is used.
The steel hinge line of existing common bolt is common steel hinge line, and the anchor pole center is a madjack pipe, and steel hinge line is located by spacer, and after anchor pole was finished mission, the steel hinge line in the anchor pole can not split out, and can only forever build in concrete.Not only waste steel, also can cause the destruction of underground environment.Permit no. the city of common bolt at some, if it is very high, long in time limit to support cost in doing, deep big foundation pit particularly, the duration is longer.
The purpose of this utility model provides a kind of line formula recoverable anchor rod of holding, and after anchor pole is finished mission, steel hinge line can be regained, and removes anchor pole, saves material, avoids causing underground public hazards.
The technical solution of the utility model is:
A kind of line formula recoverable anchor rod of holding, the anchor pole center is a madjack pipe, steel hinge line is located by spacer, it is characterized in that: steel hinge line is a unbonded prestressing tendon, anchored end headgear at anchor pole has a cylindrical supporting body that through wires hole and mud jacking hole are arranged, the supporting body lower surface connects the circular loaded plate that through wires hole and mud jacking hole are arranged, and is connected with the guider of taper, passes the steel hinge line end of through wires hole and is held with a firm grip by gripping device; By the fixing steel hinge line of cylindrical fixator, loaded plate in the middle of the lower surface of fixator connects passes the steel hinge line end of through wires hole and is held with a firm grip by gripping device in increase place of steel hinge line radical.
Above-mentioned gripping device is a cylindrical tube, and inside is extruded with holds wire spring, and steel hinge line passes holds wire spring.
Hold the manufacturing process of line formula recoverable anchor rod:
Creep into pore-forming earlier, adopt mud off, clear then hole; Make unbonded prestressing tendon with steel hinge line outsourcing isolated material or sleeve pipe; According to design carrying needs, the every interval of anchor pole increases the steel hinge line radical for one section; Steel hinge line is fixed by fixator, spacer and is located, and by supporting body and loaded plate carrying, is held with a firm grip in the end by gripping device, after ground assembles madjack pipe, steel hinge line, loaded plate, supporting body, gripping device, fixator, spacer, puts into boring; By madjack pipe slip casting, mend slurry with slush pump then; Use the jack tension steel hinge line then, and locking.Bond stress by steel hinge line and anchoring body is transmitted pulling force, makes the anchoring body pressurized at last, gives a back of the body of slope protection pile or diaphragm wall pulling force.When anchor pole is finished its function of use, steel hinge line is extracted withdrawal from gripping device with jack.
The utility model has the advantages that: after anchor pole is finished mission, can dismantle, regain steel hinge line, save material; Can not damage underground environment; The support cost is low in likening to, the duration short; Stressed better than tension type anchor pole, can shorten anchoring section.Be applicable to that supporting and protection structure does not allow the engineering of making common bolt and claiming anchor pole back.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is supporting body, loaded plate, guider combination schematic diagram.
Fig. 3 is through wires hole, the injected hole position view of supporting body, loaded plate, fixator, spacer.
As shown in the figure, this holds line formula recoverable anchor rod, the anchor pole center is a madjack pipe 4, steel hinge line 1 is by spacer 5 location, steel hinge line 1 is a unbonded prestressing tendon, at the anchored end headgear of anchor pole a cylindrical supporting body 6 that through wires hole and mud jacking hole are arranged is arranged, and supporting body 6 lower surfaces connect the circular loaded plate 8 that through wires hole and mud jacking hole are arranged, with guider 7 welding of taper, pass the steel hinge line end of through wires hole and hold with a firm grip by gripping device 9; According to design carrying needs, anchor pole increases the steel hinge line radical every one section, and by the fixing steel hinge line of cylindrical fixator 2, the lower surface of fixator 2 connects middle loaded plate 3 in increase place of steel hinge line radical, is held with a firm grip by gripping device 9 in every steel hinge line end; Gripping device 9 is cylindrical tubes, and inside is extruded with holds wire spring, and steel hinge line passes holds wire spring; In the centre of supporting body, loaded plate, middle loaded plate, fixator, spacer is mud jacking hole 11, and the periphery is a through wires hole 10; Spacer 5 be 1.5-2 rice at interval.
