Summary of the invention
The purpose of this utility model is to provide a kind of recyclable anchor cable of a kind of civil engineering of simple in structure, easy to use, recyclable utilization.
The gripping device that uses when another purpose of the present utility model is to provide a kind of recyclable anchor cable of civil engineering easy to use to reclaim.
Last purpose of the present utility model is achieved in that a kind of recyclable anchor cable of civil engineering, and wherein: this recyclable anchor cable is made up of steel strand, sleeve pipe, connector and anchorage block; One end of steel strand is fixedlyed connected with connector, is removable the connection between connector and the anchorage block, and casing pipe sleeve is on the junction of steel strand, connector and connector and anchorage block.Anchorage block is anchored in the interior solidfied materials such as cement paste of boring, and sleeve pipe is kept apart solidfied materials such as steel strand, connector and cement paste.
The further improvement project of the utility model is: removable between connector and the anchorage block is connected to be threaded to good, the convenient steel strand that reclaim.
The utility model also can be realized like this: the removable connection between connector and the anchorage block is that rotary snapping connects.
The utility model can also be realized like this: anchorage block is provided with the anchoring reinforcement.
Back of the present utility model one purpose is achieved in that the gripping device that a kind of recyclable anchor cable of civil engineering uses when reclaiming, wherein: this gripping device is made up of tubular body, screw rod, the endoporus of tubular body is slightly larger than steel strand, be provided with the screw that is used for fixing steel strand at the tubular body side, screw rod is located in the screw.
Gripping device of the present utility model can be provided with handle on tubular body, the manual steel strand of twisting during convenient the recovery; The main body of gripping device can also be connected use with dynamic power machine.
The utility model is owing to adopt said structure, the anchor cable that has solved the temporary structure supporting well reclaims problem, sustainable development to urban underground space has far reaching significance, have simple, processing ease reliable, recovery speed is fast, with low cost, has vast potential for future development.Compared with prior art, have more following advantage:
1) simple in structure, processing ease is reliable, and recovery speed is fast, generally speaking can be by manually finishing during recovery.
2) do not need special recovery line, save material.And in the prior art, except that working cable, generally all be provided with special recovery line.
3) can be designed to the single cable type reclaiming type anchor bar, promptly anchor cable only is steel strand, and this is to being applied to shotcrete rock bolt wire mesh support and soft clay area bolt support highly significant.And in the prior art, generally all be made as more than two ropes prior art that has even can only be made as the even numbers anchor cable.
4) can not recovery section in the anchor pole less, with low cost.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is done to describe further, but do not constitute any restriction of the present utility model.
As shown in Figure 1, the recyclable anchor cable of civil engineering of the present utility model is made up of steel strand 1, plastic bushing 2, connector 3 and anchorage block 4.One end of steel strand 1 is fixedlyed connected with a wherein end of connector 3 by extended type OVM-P type ground tackle 11, and by being threaded, anchorage block 4 surface soldered have bar dowel as anchoring reinforcement 41 between the other end of connector 3 and the anchorage block 4; Steel strand 1, OVM-P type ground tackle 11 and connector 3 are through in the plastic bushing 2, along steel strand 1 stop 5 are set every about 1.0m in plastic bushing 2, so that do not twine mutually between each steel strand 1; Sealing and fixing between plastic bushing 2 and the anchorage block 4 in order to avoid liquid such as water or cement mortar enter in the plastic bushing 2, is provided with a locator about plastic bushing 2 outer every 2.0m.Steel strand 1 total length, connector 3 oilings are antirust, and also oiling is antirust with anchorage block 4 connecting threads for connector 3.
