The invention discloses a barb type grouting anchor rod and belongs o the technical field of anchor rods. The barb type grouting anchor rod comprises an anchor rod body. Multiple reinforcing steel bar barbs are distributed at the front end of the anchor rod body in the circumferential direction of the anchor rod body. A grouting hole is formed in the middle of the anchor rod body in the length direction of the anchor rod body. By means of arrangement of the reinforcing steel bar barbs, stationarity achieved between the anchor rod and a rock-soil body is enhanced; the anchor rod is effectively prevented from sliding outwards; and by means of a spiral rib plate, the contact area between the anchor rod and the rock-soil body is increased, the anchor rod is further prevented from sliding outwards, and stability of the anchor rod is improved.
