Description
Technical field
The present invention relates to field of civil engineering, more particularly to the recovery method of recovery type bar reinforcement anchor pole and anchor pole.
Background technology
In Supporting Structure of Deep Foundation Pit in City, as urban land is more and more in short supply, it is red that conventional anchor pole often passes through land used
The underground space beyond line, easily cause underground space property right dispute, and be unfavorable for later stage engineering construction, put into effect file limitation more
Conventional anchor pole uses, and is arisen accordingly, with respect to reclaiming type anchor bar technology.
In deep foundation pit support, anchor pole is an important technical, two kinds of " campshed cable bolting " and " combined bolting and shotcrete "
Anchor pole is used in support technology, high-tonnage prestressed cable technology has been invented in " campshed cable bolting ", in specific bar
Had a clear superiority under part.Good in some geological conditions, depth or the place discrepancy in elevation is not big for cutting depth, and soil pressure difference is big and supporting
" full combined bolting and shotcrete structure " can be used in the deep-foundation pit engineering of force unbalance or " top is using anchor rod type spray anchor+bottom campshed
Supporting " combination supporting form, technological rationality and engineering adaptability are more preferable, such as reclaim Anchor Cable Technique using large-tonnage, not only anchor
Rope construction cost is high, and anchor cable effect counterforce structure rigidity is big, often needs to set larger cross-section concrete breast beam, the supporting construction
Cost is high.Therefore need to invent a kind of skill of the above-mentioned large-tonnage recovery anchor cable of recoverable bar reinforcement anchor pole solution under given conditions
Art irrationality.
Disclosed in the patent that State Intellectual Property Office announces（Bulletin）Carried in a kind of number 204402526U " reclaiming type anchor bar "
Gone out a kind of recovery method, it by with rust preventive coating set outside externally threaded interior bar and tapped supporting body, interior bar, hold
PVC disrance sleeves and backing plate and nut composition by interior bar locking on the carrier are covered on carrier lateral wall.Above-mentioned anchor pole
Recovery construction and recovery method can have the defects of different degrees of during specifically used.
" a kind of reclaiming type anchor bar " as described above, processing internal sealing plug is more difficult on bearing plate, and precision is low, is extremely difficult to
Anchor recovering requirement.
" a kind of reclaiming type anchor bar " as described above, supporting body and between externally threaded interior bar without anti-seep measure, slip casting
When slurry can leak into supporting body with externally threaded interior bar junction, causing recovery difficult or even can not reclaim.
" a kind of reclaiming type anchor bar " as described above, because anchor pole belongs to pressure type anchor rod, easily in anchor in work progress
Solid termination produces a large amount of slag inclusions, slurry low intensity, if not setting reinforcing mechanisms in pressure-bearing Board position, anchor pole bearing capacity compared with
It is low, it is unable to reach design requirement.
Therefore, it is necessary to the bearing capacity applied in a kind of city pattern foundation pit supporting structure not deep in the preferable cutting depth of geological conditions compared with
Recoverable reinforced anchor bolt that is high and being easily recycled.
The content of the invention
The invention provides a kind of recyclable and higher bearing capacity recovery type reinforced anchor bolt.
The present invention is a kind of recovery type bar reinforcement anchor pole and recovery method, and recovery type bar reinforcement anchor pole includes the outer silk of termination band
The bar reinforcement body of rod of head（001）, it is characterised in that the bar reinforcement body of rod（001）Pass through silk head outside reinforcing bar（007）With retracting device spiral shell
Cap（003）Connection, retracting device nut（003）With bearing plate（002）Connected by full weld, termination protecting bin（004）With pressure-bearing
Plate carries out full weld connection, PVC sleeve pipes（006）Pass through locating ring（005）With bearing plate（002）Bottom connects, PVC sleeve pipes（006）
With bearing plate（002）Between use antiseep separation layer（009）Sealed, locating ring（005）With bearing plate（002）Full weld connects
Connect, Reinforced Hoop is held at end（008）With bearing plate（002）Spot welding connects.
A kind of recovery type bar reinforcement anchor pole bearing plate of the present invention（002）Hold Reinforced Hoop in overcoat end（008）, reduce because applying
A large amount of slag inclusions are produced in anchoring body termination and influence anchor pole bearing capacity during work.Substantially increase anchor pole bearing capacity.
A kind of recovery method of recovery type bar reinforcement anchor pole, its step are： 1）With the punching jack tension reinforcing bar body of rod
（001）Exposed parts, anchor rod anchored component is removed, discharge anchor force； 2）It is counterclockwise with spanner or other instruments of the technical field
Direction twists the Swiveling Rebar body of rod, until the reinforcing bar body of rod（001）With retracting device nut（003）Depart from； 3）By the reinforcing bar body of rod
（001）Pull out recovery.
The beneficial effects of the invention are as follows：By the counterclockwise rotates reinforcing bar body of rod, make the reinforcing bar body of rod（001）Filled with recovery
Put nut（003）Depart from, quickly pull out and reclaim the reinforcing bar body of rod（001）, its recovery is quick and easy, both saves construction costs, again
Building waste will not be produced in the underground space, reach the requirement of environmental protection.
