Description
Technical field
The invention patent relates to side slope or tunnel support technical field, specially a kind of increasing resistance pressurization anchor pole.
Background technique
Anchor pole is as the important component in side slope tunnel work progress, when side slope is reinforced, existing anchor pole
It generally requires and first makes a call to a hole in side slope, then anchor pole is inserted into hole, last slip casting, until slurry solidification later just can be with
Reinforcing country rock, dispersion and transmitting high stress are played, the effect of rock displacement is limited, the construction method of this anchor pole has construction step
Rapid relatively complicated, the duration is longer, and reinforcing resistance pressure may be not big enough, and the drawbacks such as the purpose of supporting country rock are not achieved.
Summary of the invention
The invention patent problem to be solved is to provide a kind of increasing resistance pressurization anchor pole, passes through mechanical increase anchor pole
Resistance between country rock.To solve long construction period, the problems such as complex steps, resistance is inadequate.
To solve the above problems, the technical scheme adopted by the invention is that: a kind of increasing resistance pressurization anchor pole,
In, including, anchor sleeve, its underpart is provided with several screw holes along two sides: upper part is equipped with hold-down mechanism and pallet: bar
Body is sheathed in the anchor sleeve, and the upper and lower ends of the body of rod extend to outside the anchor sleeve respectively: the lower end of the body of rod is in
Semicircle and with sawtooth, the upper end of the body of rod is round and is connected with screw thread with pressurizing nut.
It preferably, further include one end and the occlusion of body of rod lower end sawtooth, one end is screwed into anchor sleeve screw hole in above-mentioned technical proposal
Polygonal screw.
Preferably, in above-mentioned technical proposal, the lower end edge two sides of the anchor sleeve are provided with uniform screw hole.
Preferably, in above-mentioned technical proposal, the upper end of the anchor sleeve is provided with figure disk and hold-down mechanism, the anchor sleeve
Be provided with external screw thread corresponding with hold-down mechanism.
Preferably, in above-mentioned technical proposal, the body of rod lower end is semicircle zigzag, and can mutually be stung with polygonal screw
It closes.
Preferably, in above-mentioned technical proposal, the body of rod upper end is round with export-oriented screw thread and the anchor sleeve inner ring
It is close to.
Preferably, in above-mentioned technical proposal, the upper end of the body of rod is provided with clamp nut corresponding with export-oriented screw thread.
Following good effect is produced using above technical scheme.
After present invention insertion is drilled in the guide hole in side slope, by the rotation of fixed device fixed core, and rotates and add
Nut is pressed, allows the body of rod to Outer shrink, the body of rod is shunk outward drives polygonal screw rotation, and polygonal screw leans out anchor sleeve lower end
Screw hole compresses and even pierces rock mass.
Increasing resistance pressurization anchor pole of the invention can be after being inserted into guide hole, and on periphery, ore-rock body does not occur stress variation or answers
Implement advanced anchoring when power variation is smaller, significantly increases the resistance pressure of anchor pole and rock mass, increase substantially anchoring
Reliability.
It is being used for permanent anchorage.It does not need in the case where removing recycling, the body of rod can be taken out after pressurization, and in anchor sleeve
The materials such as inside and outside injection expanding cement wait its expansion, and this method can not only save material, and can further enhance anchor
Gu effect.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
The embodiment of the present invention, every other reality obtained by those of ordinary skill in the art without making creative efforts
Example is applied, shall fall within the protection scope of the present invention.
As shown in Figs 1-4, a kind of increasing resistance pressurization anchor pole, including anchor sleeve 1, the inside of anchor sleeve 1, which will be set with, wants rod piece 2,
The two passes through two rows of bolts 7 and is connected.
The top of anchor sleeve 1 is provided with external screw thread, the hold-down mechanism equipped with pallet 9 and limit pallet outside male thread portion
4。
Nut 6 and rod piece 2 are connected through a screw thread.
The middle section of the pallet 9 is equipped with a hole so that rod piece 2 passes through.
The lower end two sides axis of the anchor sleeve 1 is equipped with two rows of symmetrical screw holes 3, and the lower end of the body of rod 2 is half
