Description
Technical field
Expand hair style resistance to plucking anchor the present invention relates to a kind of mechanical linkage, belong to civil engineering side slope and dam strengthening technology
Field, it can be used for the engineering constructions such as tunnel, side slope, mine, tunnel, dam body, foundation ditch, foundation stabilization.
Background technology
In the engineerings such as foundation pit enclosure, slope reinforcement, in order to prevent being slid inside Rock And Soil, failure by shear is produced,
, it is necessary to carry out consolidation process to Rock And Soil before later stage process is carried out, to strengthen the stability of Rock-soil Mass Structure, often at present
The anchor pole used is mechanical rock bolt, pipe-seam type anchor rod and adhesive type anchor pole.
The A of Publication No. CN 104929670 Chinese patent discloses a kind of mechanical anchor pole of wing formula.The anchor pole is by anchoring spiral shell
Cap, washer plate, anchor rod body, retaining pin, push wing steel pipe, positioning bar, wing, the wing opened, reinforcing bar annulus, wing bending ring,
Supporting station post is constituted, and the wing formula anchor pole has a cylindrical anchor rod body, is provided with what can be extended in the bottom of anchor rod body
Wing, reinforcing bar annulus and the wing bending ring of plate shape, are provided with supporting station post, supporting station post between wing bending ring and anchor rod body
Weld together with anchor rod body, wing bending ring one end is welded on wing root, and spiral-lock is between two supporting station posts
In the hole of reinforcing bar annulus, push wing steel pipe is housed in the top slip cap of reinforcing bar annulus, it is equal in 120 degree on the surface of push wing steel pipe
Even distribution is welded with reinforcing bar positioning bar;
The Y of Publication No. CN 201031391 Chinese patent discloses a kind of umbrella Pulling-Resistant Anchor Rod.The anchor pole is twisted by power transmission
Rope and lower sleeve portion, low bottom-disc, top bottom-disc, balancing pole, from spreader bar composition, under a stretching force, the umbrella wing be balancing pole and from expand
Bar opens, and forms floor space very thick earth pillar, is provided using the soil body weight in itself and soil with the soil shearing strength of itself
The required withdrawal resistance in basis.
The U of Publication No. CN 202559350 Chinese patent discloses a kind of Pulling-Resistant Anchor Rod, and the bolt body is vertically arranged
There is at least one locator.The locator includes three positioning convex rings that ring bolt body excircle is uniformly arranged.It is described fixed
Position bulge loop forms isosceles trapezoidal structure by base of bolt body, and at least one locator is vertically provided with bolt body, because
And improve pulling test strength.
What above patent was used is all mechanical rock bolt, and its feature is that good mechanical property, anchoring effect are good, in side slope plus
Gu and it is used widely in foundation pit enclosure construction.However, in Practical Project, anchor pole duct inwall is by disturbance, its rock
Soil disturbance is more violent, and anchoring effect limits to very much, easily causes and is disengaged with Rock And Soil, and anchor pole is directly pulled out from duct.This
Outside, the anchoring face of general mechanical rock bolt is smaller, and the contact surface between Rock And Soil is less, it is impossible to meet the work under big stress
Range request.
In summary, a kind of more effective anchor pole is developed, for slope reinforcement and foundation resistance to plucking, anti-floating right and wrong
Often it is necessary.
The content of the invention
In order to overcome the drawbacks described above that existing machinery formula anchor pole is present, the present invention provide a kind of simple structure, reasonable stress,
The splendid mechanical linkage of quick construction, anchoring effect expands hair style resistance to plucking anchor.
The technical solution adopted by the present invention is:
A kind of mechanical linkage expands hair style resistance to plucking anchor, including bolt body, and described bolt body is included in the embedded soil body
Anchoring section and free segment for anchoring anchoring section, it is characterised in that:Described anchoring section has a support disk, described
Offered on support disk in being respectively arranged with the connected pore channel of two insertion total lengths, the inwall of the connected pore channel described in two
Be provided with stress cage bar in screw thread, and described connected pore channel, one end of described stress cage bar through connected pore channel and
End has bending head, and the other end upwardly extends to form described free segment;In described stress cage bar have with it is described in
The external screw thread of screw thread mating reaction;
During initial position, the bending direction of the bending head of the stress cage bar described in two is towards the center side of support disk
To the described bending head of described support disk covering;After described stress cage bar rotates 180 degree, two stress cage bars
Bending head is outwards rotated and stretches out support disk, and bending direction is oppositely arranged, and described bending head is formed in the end of anchoring section
Enlarged footing.
The position for also including correspondence stress cage bar on steel plate washer, described steel plate washer offers two through holes, and described
Stress cage bar be fixed on by steel plate washer on Tu Bi.
In the present invention, in order to which the internal thread ensured in external screw thread and duct is filled by the soil body, can smoothly it enter to rotate
OK, certain closed protective need to be carried out to anchoring section in advance, can be wrapped up using temporal material.
The present invention is by the way that after free segment carries out force tensioning to control reinforcing bar, anchor head section forms an enlarged footing, passes through
The cooperation of internal and external threads, originally the bending head of anchor head muscle be hidden in round tray plane.Free segment Strong Wrench to by
Advocate muscle carry out rotation 180 degree, bending head rotate to outside plane so as to formed one expansion anchor head, then to stress cage bar carry out
Exert a force tensioning.Enlarged footing adds the contact area between anchor pole and Rock And Soil, so substantially increase itself and Rock And Soil it
Between anchor force, anchoring effect is very good.
Beneficial effects of the present invention are embodied in:
1st, enlarged footing of the invention adds the contact area between anchor pole and Rock And Soil, so substantially increase its with
Anchor force between Rock And Soil, anchoring effect is very good.
2nd, intensity height, good toughness, anchoring effect are good, available for engineering construction fields such as dam strengthening, tunnel reinforcements;Have
Quick construction, efficiently, good endurance the advantages of.
Brief description of the drawings
Fig. 1 is front view of the invention.
Fig. 2 is top view of the invention.
Embodiment
Referring to Figures 1 and 2, a kind of mechanical linkage expands hair style resistance to plucking anchor, including bolt body, described bolt body bag
The anchoring section in the embedded soil body and the free segment for anchoring anchoring section are included, described anchoring section has a support disk 1, described
Support disk 1 on offer and set respectively on the connected pore channels of two insertion total lengths, the inwall of the connected pore channel described in two
There is an internal thread 11, and be provided with stress cage bar 2 in described connected pore channel, one end of described stress cage bar 2 is through connection
Duct and end have bending head 22, and the other end upwardly extends to form described free segment;Have in described stress cage bar 2
With the external screw thread 21 of the described mating reaction of internal thread 11;
During initial position, in the bending direction direction support disk 1 of the bending head 22 of the stress cage bar 2 described in two
Heart direction, described support disk 2 covers described bending head 22;After described stress cage bar 2 rotates 180 degree, two by
Advocate muscle 2 bending head 22 outwards rotate and stretch out support disk 1, bending direction is oppositely arranged, and described bending head 22 is in anchor
Gu the end of section forms enlarged footing.
