Carbon fiber bundle comprising a rock anchor locking hole expandability and manufacturing method thereof

Rock anchor comprises a self-locking reamer carbon fiber bundle, including the anchor, and a lock hole provided inside the outer, split-type tube; wherein a plurality of anchor rod bundles of carbon fibers, the carbon fiber bundle sequentially drawing-lock the top of the head, the bottom of the hole to secure the mounting clip, to the top flap of the petal tube portion disposed above the top of the lock cylinder, the lock at the top of the bottom, is provided between the bottom and the petaloid an outer bottom hole bottom portion defines a bottom counterbore hole wall is connected; production, first outer aperture opened, and then the carbon fiber bundle assembly, lock, and placed outside the hole, and then set on the carbon fiber bundle pressurizing the sleeve to the split of the formula pressure tube until the front end of the bottom wall of the hole reamed petals spread portion is connected to function as a mechanical anchoring effect, and then removed sequentially pressing sleeve, grouting can be solidified. This design not only has both chemical grouting anchor force, mechanical anchoring force, and anti-aging, anti-fatigue properties.
