Abstract
A kind of tension type detachable anchor, which is characterized in that the anchor pole includes steel wire bundle (1), resin transition zone (2)；The steel wire bundle (1) is the hinged steel wire of multiply, and the resin transition zone (2) is coated on the outside of steel wire bundle (1).The configuration of the present invention is simple can easily take out steel strand wires.
Description
Technical field
The present invention relates to a kind of tension type detachable anchors.
Background technique
The development utilized with urban underground space, the stake anchorage technology in pattern foundation pit supporting structure are widely applied.However anchor
A large amount of uses of bar, the anchor pole for causing Urban Underground embedding is more and more, and anchor pole, which extends to outside land red-line to have constituted a serious infringement, to be faced
The underground space closely built leaves hidden danger for successive projects construction, also causes seriously to pollute to urban underground space.
With the enhancing of property right consciousness and the reinforcement of environmental protection consciousness, anchor pole gradually be limited using meeting, and anchor pole makes
With needing to recycle anchor pole after the completion of function, so that the Recoverable ligand of anchor pole gradually starts to promote and apply.And anchor pole
It is recycling after recycling to generate higher economic value and social value.
Currently, the Recoverable ligand subordination of anchor pole is in pressure type anchor rod technology, by the way that various casings are arranged outside anchor pole,
Dismountable anchorage is arranged to realize the recycling of anchor pole in anchor pole bottom end.Pressure-type recoverable anchor rod technology needs the anchorage of end to send out
Wave stronger effect, it is relatively high to the slip casting Seed harvest quality requirement of anchor pole end, and when anchor recovering end anchorage without
Method recycling.
Anchorage technology is divided into tension type anchorage technology, pressure-type anchorage technology and tension and compression mating type anchorage technology.It is right at present
Pressure-type anchorage technology is only used in the steel strand wires detachably recycled.
From stress condition to construction complexity for, tension type anchorage technology advantageously than pressure-type anchorage technology,
And tension type anchor structure is simple, and easy for construction, cost is lower.Especially under conditions of construction environment is extremely severe especially
It is applicable in.But all non-dismountable recycling of tension type anchor pole so far, anchor pole stays in soil after the completion of construction, causes environment dirty
Dye, water and soil pollution, metal loss.If tension type anchor pole being realized to, detachable recycling will generate very high economic value
And social value.
Summary of the invention
The invention patent is designed to provide a kind of tension type detachable anchor, which is characterized in that the anchor pole includes steel
Strand bundle (1), resin transition zone (2)；
The steel wire bundle (1) is the hinged steel wire of multiply, and the resin transition zone (2) is coated on steel wire bundle (1)
It is external.
The resin transition zone (2) with a thickness of 2-3mm.
The steel wire bundle (1) is made of 5-10 strands of hinged steel wires.
The steel wire bundle (1) has multi beam, passes through energization anchor ear (9) formation power circuit between every beam
The material of the resin transition zone (2) is compound resin.
The outside of the resin transition zone (2) has bellows (3).
Beneficial effect：
1, the present invention by going out package one layer of resin transition zone of setting in steel strand wires or muscle in vitro, and resin transition zone is in anchor pole
The transmitting of power between steel strand wires or muscle body and slip casting Seed harvest may be implemented in use process, and total is made to form tension type anchoring
System avoids pressure-type anchoring system to the high request of bottom end grouting quality.
2, the present invention by going out package one layer of resin transition zone of setting in steel strand wires or muscle in vitro, and resin transition zone is in anchor pole
By being dropped to steel strand wires or the energization of muscle body so that steel strand wires or muscle body heat and then soften resin transition zone after the completion of use
Frictional force between low steel strand wires or muscle body and slip casting Seed harvest (5), and then by applying in the outer end of steel strand wires or muscle body
Pulling force takes out steel strand wires or muscle body.
3, the present invention by going out package one layer of resin transition zone of setting in steel strand wires or muscle in vitro, and resin transition zone is in anchor pole
The transmitting that power between steel strand wires or muscle body and slip casting Seed harvest (5) may be implemented in use process is led to after the completion of anchor pole use
It crosses the frictional force heated and softened reduce between steel strand wires or muscle body and slip casting Seed harvest and then takes out steel strand wires or muscle body.And
Such anchor structure system is tension type anchoring system in use, higher than the safety of pressure type anchor rod system.
4, it is being set between the resin transition zone and slip casting Seed harvest (5) of every steel strand wires in another embodiment
A bellows (3) is set, convenient for the formation of resin transition zone, and reduces steel strand by heating and softening after the completion of anchor pole use
Frictional force between line or muscle body and slip casting Seed harvest in turn takes out steel strand wires or muscle body.
