Description
Technical field
The present invention relates to a kind of mechanical linkage Pulling-Resistant Anchor Rods, belong to civil engineering side slope and dam strengthening technical field,
It can be used for the engineering constructions such as tunnel, side slope, mine, tunnel, dam body, foundation pit, foundation stabilization.
Background technology
It in the engineerings such as foundation pit enclosure, slope reinforcement, is slid inside Rock And Soil in order to prevent, generates failure by shear,
It before carrying out later stage process, needs to carry out consolidation process to Rock And Soil, to enhance 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 Chinese patent of 104929670 A of Publication No. CN discloses a kind of wing formula machinery anchor pole.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 of opening, reinforcing bar annulus, wing bending ring,
Supporting station column forms, and there are one cylindrical anchor rod body, being equipped in the lower part of anchor rod body can extend the wing formula anchor pole
Wing, reinforcing bar annulus and the wing bending ring of plate shape are equipped with supporting station column, supporting station column 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 columns
In the hole of reinforcing bar annulus, push wing steel pipe is housed in the top sliding sleeve 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 Chinese patent of 201031391 Y of Publication No. CN 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 form, under a stretching force, the umbrella wing, that is, balancing pole and from expand
Bar opens, and forms the very thick earth pillar of floor space, is provided with the native shearing strength of itself using the weight and soil of the soil body itself
The required withdrawal resistance in basis.
The Chinese patent of 202559350 U of Publication No. CN 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 bottom edge of bolt body, and at least one locator is vertically provided in bolt body, because
And improve pulling test strength.
What above patent used is all mechanical rock bolt, and feature is that good mechanical property, anchoring effect are good, in side slope plus
Gu and being used widely in foundation pit enclosure construction.However, in Practical Project, anchor pole duct inner wall is by disturbance, rock
Soil disturbance is more violent, and anchoring effect limits to very much, be easy to cause 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, cannot meet the work under big stress
Range request.
In conclusion a kind of more effective anchor pole of exploitation, is used for slope reinforcement and foundation resistance to plucking, anti-floating right and wrong
Often it is necessary to.
Invention content
In order to overcome drawbacks described above existing for existing machinery formula anchor pole, the present invention provide a kind of simple structure, reasonable stress,
The splendid mechanical linkage Pulling-Resistant Anchor Rod of quick construction, anchoring effect.
The technical solution adopted by the present invention is：
A kind of mechanical linkage Pulling-Resistant Anchor Rod, including bolt body, the bolt body include the anchoring in the embedded soil body
Section and the free segment for anchoring anchoring section, it is characterised in that：The anchoring section has a support pallet, the supporting bracket
Disk is provided centrally with connecting shaft, and four anchor rods are hinged in the connecting shaft；Corresponding anchoring on the support pallet
The position of bar opens up that there are four the connected pore channels of perforation overall length, is provided with vertical applied force main reinforcement in the connected pore channel, four
One end of the vertical applied force main reinforcement pass through connected pore channel and respectively with the middle part of corresponding anchor rod connect, the other end to
Upper extension constitutes free segment；The anchor rod be tightly attached under the traction of vertical applied force main reinforcement support pallet bottom surface, four
Anchor rod forms decussate texture and is in close contact with Rock And Soil.
Further include billet, the position that vertical applied force main reinforcement is corresponded on the billet is opened up there are four through-hole, and
The vertical applied force main reinforcement is fixed on by billet on Tu Bi.
In order to ensure that the anchor rod of stretching, extension can be located in well in the plane of support pallet, every anchor rod is all with one
Root vertical applied force reinforcing bar be rigidly connected, be secured under tension support pallet plane on, finally free segment by
After the completion, the anchor rod of four expansion becomes a spider, is in close contact with Rock And Soil, is finally mounted in inside the soil body.
Beneficial effects of the present invention are embodied in：
1, vertical applied force main reinforcement is made of the fabulous mild steel of tension effect, and anchor rod is vertically being drawn by lacing wire
Under, one enlarged footing of flare up after the completion of tensioning, interacts between entire anchor pole and the soil body, and anchor pole starts to play anchoring, resist
The effect of pulling out.
2, intensity height, good toughness, anchoring effect are good, can be used for the engineering construction fields such as dam strengthening, tunnel reinforcement；Have
Quick construction, efficiently, the advantages that durability is good.
3, its material stiffness is big, and structural stability is good, and enlarged footing increases the contact area between anchor pole and Rock And Soil, into
And its anchor force between Rock And Soil is substantially increased, anchoring effect is preferable.
