Root key type pressure bearing mechanism in anchor hole, root key type anchor cable and anchor hole grouting method
The present invention discloses a root key type pressure bearing mechanism in an anchor hole, a root key type anchor cable and an anchor hole grouting method. The pressure bearing mechanism includes a carrier, root keys and a tapered plug, a through hole is formed in the center of the tapered plug, a taper hole is formed in the center of the carrier, key holes are formed along a radial direction of the carrier with an inner wall of the taper hole as a starting point, the number of the key holes is the same as that of the root keys, the root keys and the key holes constitute sliding pairs, an outer wall of the tapered plug is adapted to the taper hole, the sum of the length of the root key and the radius of a position corresponding to the tapered plug is larger than the radius of the anchor hole, and the length of the root key is less than the radius of the anchor hole; and when the tapered plug is plugged into the taper hole, the head of the root key stretches into a rock mass of the anchor hole. The pressure bearing mechanism assembled by the assembly method is applied to the anchor cable, and when the anchor cable is used for grouting, the anchoring effect of the anchor cable can be effectively improved.
