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 Publication No. CN104929670A 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 Publication No. CN201031391Y discloses a kind of umbrella Pulling-Resistant Anchor Rod.The anchor pole is by power transmission strand cable
And lower sleeve portion, low bottom-disc, balancing pole, are formed from spreader bar top bottom-disc, and under a stretching force, the umbrella wing, that is, balancing pole and from spreader bar
It opens, forms the very thick earth pillar of floor space, base is provided with the native shearing strength of itself using the weight and soil of the soil body itself
Withdrawal resistance needed for plinth.
The Chinese patent of Publication No. CN202559350U discloses a kind of Pulling-Resistant Anchor Rod, which is vertically provided with
At least one locator.The locator includes three positioning convex rings that ring bolt body excircle is uniformly arranged.The positioning
Bulge loop forms isosceles trapezoidal structure by bottom edge of bolt body, and at least one locator is vertically provided in bolt body, thus
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 anchor pole, a kind of simple structure of present invention offer, reasonable stress, construction fast
Mechanical linkage Pulling-Resistant Anchor Rod prompt, anchoring effect is splendid.
The technical solution adopted by the present invention is:
Mechanical linkage Pulling-Resistant Anchor Rod, including bolt body, the bolt body include anchoring section in the embedded soil body and
Free segment for anchoring anchoring section, it is characterised in that:The anchoring section has a round tray, on the round tray
It opens up there are three the connected pore channel of perforation overall length, rotation roller bearing, and the company of both sides is installed in the connected pore channel of both sides
It is provided with stress main reinforcement in through-hole road, is connected by the lock silk below round tray between two stress main reinforcements;Described
One end of stress main reinforcement passes through connected pore channel and end to have bending head, and the stress main reinforcement is under the action of rotating roller bearing
It can Plane Rotation 180 degree;
Reinforcing bar is provided in intermediate connected pore channel, one end of the reinforcing bar passes through intermediate connected pore channel and end
Portion is connected with the blade for cutting off lock silk;When initial position, the bending direction of the bending head of two stress main reinforcements is towards circle
The center position of shape pallet;After locking silk disconnection, the bending head of two stress main reinforcements rotates outward and stretches out round tray, bending side
To being oppositely arranged, the bending head forms enlarged footing in the end of anchoring section.
Further include steel plate washer, the position that stress main reinforcement and reinforcing bar are corresponded on the steel plate washer opens up that there are three through-holes, and
And the main reinforcement is fixed on by steel plate washer on Tu Bi.
Beneficial effects of the present invention are embodied in:Using Pulling-Resistant Anchor Rod made of mechanical linkage, intensity height, good toughness,
Anchoring effect is good, can be used for the engineering construction fields such as dam strengthening, tunnel reinforcement;With quick construction, efficiently, durability it is good etc.
Advantage.
