Zusammenfassung:A novel anti-shearing grouting anchor rod for bedding development rock mass comprises an expansion shell anchor head (1), a carbon fiber strip (2), an anchor rod body (3), a base plate (4), a grouting bag (5), a nut (6) and a grouting hole (7). The expansion shell anchor head is mounted at one end of the anchor rod body; a base plate is installed at the other end of the anchor rod body, a grouting bag is installed on the base plate, and a pipeline is formed by the grouting bag and a grouting hole of the anchor rod body. The anchor rod body is a prestressed hollow grouting anchor rod, and carbon fiber strips are distributed on the periphery of the anchor rod. A plurality of longitudinal grouting holes are evenly formed in the anchor rod body in the length direction. According to the expansion shell type grouting anchor rod, the carbon fiber strips with extremely high tensile and shear resistance are adhered to the surface of the rod body of the free section of the expansion shell type grouting anchor rod, so t
