Description
Technical field
The present invention relates to a kind of engineering construction field, more particularly to a kind of glass fibre anchor pole and construction method.
Background technology
Country rock can be divided into I, II, III, IV, V, VI rank by the grade of geological conditions, just need for more than IV grade country rock
Necessary suspension roof support is carried out, when occurring crushed zone in country rock, surrounding rock stability is poor, it is impossible to from into " stress arch ", easily collapse
Collapse, cavitation is difficult, there is potential safety hazard.
When the installing hole of common metal grouted anchor bar is distributed in crushed zone, due to the rock mass of crushed zone it is extremely unstable
Fixed, during anchor pole is installed, the vibrated fragmented rock body that easily drops of installing hole inwall causes local in installing hole to occur stifled
Plug, once forming blocking, possible secondary grouting cannot also realize full slip casting, and anchor pole is perishable, it is difficult to form stable stress, together
When, in crushed zone, crack is more, if the slurry is blocked, it is impossible to fill the crack around installing hole, fracture be difficult to into
Row is effectively bonded, and surrounding fragmented rock body cannot form entirety, is not only resulted in the loss of supporting power, be also can result in collapsing when serious
Collapse, have a strong impact on the quality and safety of engineering, particularly with the longer engineering of the service lifes such as tunnel, endanger larger；It is general in addition
Logical metal material is poor to the change adaptability of geological conditions, if larger containing corrosive substance or the water yield in country rock, it will
Accelerate the corrosion and damage of anchor metal, if containing gas in country rock, machinery is collided with anchor metal, it is possible to create spark draws
Detonation is fried.
The content of the invention
It is an object of the invention to overcome existing anchor pole during the country rock that supporting contains crushed zone, easily by broken
Rock mass comes off and causes the above-mentioned deficiencies such as slip casting leakiness, supporting power difference, there is provided a kind of glass fibre anchor pole and construction method, favorably
In the density for ensureing slip casting, supporting intensity is improved, be easy to fill crack, strengthen surrounding rock stability, improve the peace of work progress
Quan Xing, it is cost-effective.
To achieve these goals, the invention provides technical scheme below：
A kind of glass fibre anchor pole, comprising anchor head, the body of rod, stop grouting plug and anchoring accessory, described body of rod one end connects the anchor head,
The other end is slidably connected the stop grouting plug and anchors accessory, and the stop grouting plug is located between the anchor head and anchoring accessory, described
The body of rod is hollow structure, and the material of the body of rod is glass fibre, and the body of rod is provided with several openings, all openings
Connect with the hollow structure of the body of rod.
It is using a kind of glass fibre anchor pole of the present invention, comprising anchor head, the body of rod, stop grouting plug and anchoring accessory, described
