Abstract
The invention discloses an unbonded prestressed construction anchor rod and belongs to the technical field of civil engineering construction. The unbonded prestressed construction anchor rod comprises a guiding head, an anchor rod outer steel tube, a main anchor rod body, an anchor pad and an anchor part and is characterized in that the main anchor rod body is made of a prestressed steel bar, a rebar or a steel cable, and the anchor rod outer steel tube is flexibly connected with the guiding head and located on the outer side of the main anchor rod body. The unbonded prestressed construction anchor rod has the beneficial effects that as that the main anchor rod body can be made of the prestressed steel bar, the rebar or the steel cable, the stress of the main anchor rod body can be adjusted continuously during construction, and process control can be achieved; the anchor rod outer steel tube is flexibly connected with the guiding head, located on the outer side of the main anchor rod body and used for foundation pit engineering maintenance, and therefore later-period backfill can be recycled in a layered or segmented mode. The unbonded prestressed construction anchor rod is simple in structure and convenient to implement.
Description
Technical field
A kind of Unbonded prestressed anchor pole, belongs to engineering construction technology field.
Background technology
Anchor pole side slope maintenance technology is very extensive in field application such as construction work, bridge highways, and technology maturity is also very high.But conventional anchor construction cost performance is not high, and because soil layer change, bolt deformation etc. are because usually causing the partial failure of anchor pole side slope in work progress, even all lost efficacy, the Engineering Projects causing security incident to occur is a lot.
Summary of the invention
The object of the invention is to realize the process control of constructing.Unbonded prestressed anchor pole can select applicable anchor pole material according to different engineering-environments, the stress of main body anchor pole constantly can be adjusted in work progress, can implementation procedure control, when discovery local, slope deforming is excessive, also can realize the Dynamic dexterity of construction process control.
Object of the present invention is by realizing with under type: a kind of Unbonded prestressed anchor pole, comprise five part compositions such as seeker, anchor pole outer steel pipe, main body anchor pole, anchor pad, anchor, it is characterized in that: described main body anchor pole adopts the materials such as prestressed steel bar, reinforcing bar, cable wire, the outer steel pipe of anchor pole is connected with seeker activity, and is placed in outside main body anchor pole.
The present invention has the following advantages compared with existing prior art: simple structure, and it is convenient to implement, and constantly can adjust the stress of main body anchor pole in work progress, can implementation procedure control; The outer steel pipe of anchor pole is connected with seeker is active, and is placed in outside main body anchor pole, and later stage backfill layering, segmentation can realize the features such as recycling, and cost performance is high.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
In figure: 1, seeker, 2, the outer steel pipe of anchor pole, 3, main body anchor pole, 4, anchor pad, 5, anchor, 6, side slope sprayed mortar or maintaining pile, 7, plastic bushing.
Detailed description of the invention
As follows with reference to accompanying drawing 1: a kind of Unbonded prestressed anchor pole, comprise seeker 1, anchor pole outer steel pipe 2, main body anchor pole 3, anchor pad 4, anchor 5, it is characterized in that: described main body anchor pole adopts the materials such as prestressed steel bar, reinforcing bar, cable wire, the outer steel pipe of anchor pole is connected with seeker activity, and is placed in outside main body anchor pole.The invention has the beneficial effects as follows that main body anchor pole can select the materials such as prestressed steel bar, reinforcing bar, cable wire, constantly can adjust the stress of main body anchor pole in work progress, can implementation procedure control; The outer steel pipe of anchor pole is connected with seeker activity, and is placed in outside main body anchor pole, safeguards for base pit engineering.
In side slope anchor bolt construction process, seeker 1, main body anchor pole 3 are squeezed in side slope soil layer together with the outer steel pipe 2 of anchor pole, completes the first step of anchor bolt construction; Due to before construction, plastic bushing 7 on the cover of the outside of main body anchor pole in advance, later stage side slope concrete ejection 4, prestressed stretch-draw, anchoring etc., can convenient construction operation.
