Abstract
The invention provides an anchoring part with recyclable anchor bars. The anchoring part comprises spiral locking type anchorage devices, a plurality of pressure diffusion plates, a bearing body, the anchor bars and a sleeve. The anchor bars are inserted into the spiral locking type anchorage devices, and by controlling the positions of bar clocking clamping plates in a conical anchor pipe, the interlocking degree between the bar locking clamping plates and the anchor bars is adjusted, and locking or unlocking separation between the bar locking clamping plates and the anchor bars are achieved. By adoption of the pressure diffusion plates and the bearing body, pressure diffusion is achieved, and the forced deformation amount of an anchoring body is controlled. The anchoring part is high in construction operability, large in anchoring force generated in soft soil, high in anchoring reliability and recycle rate of the anchor bars and efficient in construction. The anchor bars are recycled, the project construction cost is lowered, underground obstacles are removed, and a green anchoring construction technology is achieved.
Description
Technical field
The present invention relates to the control of technical field of civil engineering, more particularly to soft soil foundation pit slope deforming and deep pit support nurse
Anchoring used in journey is put more energy into piled anchor.
Background technology
At present, in the side slope and Deep Foundation Pit Supporting Project on rock and pan soil stratum, prestress anchorage cable has higher anchor
Gu power, anchored pile supporting are widely applied.But the anchoring of soft soil layer is still the bottleneck of anchorage technology.Soft soil layer
Frictional resistance is low, and the application that the deformation such as rheology limits anchorage technology is also easy to produce after stress.Additionally, frequently with steel in civil engineering
Used as prestressing force dowel, which after side slope and foundation pit enclosure structure complete mission often stays and forms barrier in underground twisted wire, this
Also limit the popularization and application of this kind of support form.Therefore, higher anchor force can be produced in soft soil layer, controls which soft
The deflection of soil, and after supporting construction mission is completed, dowel can be reclaimed from the soil body, it is that engineering circles are in the urgent need to address
A difficult problem.
In soft clay area, as water level is universal higher, the water content of weak soil is big.Meanwhile, traditional anchoring body diameter only has
100~150mm, less with the bond area of weak soil, the frictional resistance of weak soil is relatively low in addition, and the anchor force for obtaining is relatively low.Additionally, soft
Soil has rheological property, and when the prestressing force for applying is higher, the Rheological Deformation characteristic on stratum will be highlighted, and deformation is difficult to control
System.
In soft soil layer anchoring support, the anchoring body formed by removable anchorage (patent No. ZL2015203006781)
Intensity is relatively low, when applying more high-prestressed, frequently results in anchoring bulk damage.If applying less prestressing force, the control effect of deformation
Fruit is often poor.Therefore, also in the urgent need to research and development have anchor pole (rope) technology of higher anchor force to meet wanting for soft oil support
Ask.
In order to solve larger anchor force, effective control deformation, the recovery for improving anchor cable how are obtained in soft soil layer
Rate and guarantee anchoring security problems, in the urgent need to developing a kind of novel pre-stressed anchoring piece.
The content of the invention
Present invention solves the technical problem that be overcome existing Recyclable anchor rope anchor force is little, Support Deformation big and returns
The low shortcoming of yield, there is provided a kind of anchoring piece of the pressure dissipation formula Recyclable anchor rope for pattern foundation pit supporting structure, inside its anchoring body
With multiple supporting bodies, so as to improve its withdrawal resistance.After support action is completed, dowel can be reclaimed out from anchoring body
Come, anchoring body is departed from dowel, realize the recycling of dowel, reduce the purpose of construction costs.Meanwhile, removing is stayed in
Barrier in stratum.
The technical scheme is that to solve the above problems such:
A kind of dowel recoverable anchoring piece, is characterized in that, anchoring piece includes screw lock formula anchorage, pressure diffusion plate, carries
Body, dowel;The pressure diffusion plate of more than 1 is set in vivo in anchoring, and pressure diffusion front edge of board arranges screw lock formula anchorage, and pressure expands
Fall apart rear end setting supporting body, and dowel passes through supporting body and pressure diffusion plate to be connected with screw lock formula anchorage, each screw lock formula anchor
Tool pins a dowel.
The dowel is provided with sleeve pipe.
Pressure diffusion plate is distributed in anchoring body, at regular intervals each other;Pressure diffusion plate is connected to supporting body
Integrally.
Pressure diffusion plate is made up of high strength plastics or steel, and the hole of more than 1 is distributed with pressure diffusion plate.
Supporting body is in cylindrical structural, is made up of high strength plastics or steel.
Screw lock formula anchorage is by controlling position of the lock muscle clamping plate in taper anchor tube, adjusting lock muscle clamping plate with dowel
Degree of engagement, realizes locking dowel or unlocks.
Beneficial effect:A kind of dowel recoverable anchoring piece for controlling side slope and foundation pit deformation of the present invention,
The locking and unblock recycling of dowel are realized by screw lock formula anchorage, manually i.e. recyclable dowel, improves returning for dowel
Rate of producing effects and reuse ratio;By arranging multiple supporting bodies, it is to avoid anchoring body stress is concentrated, disperseed the pressure to anchoring body with
And with by the contact stress of anchoring body, so as to solve the problems, such as to reclaim, anchor force in anchor pole (rope) technology is little and deformation is big.
