The invention belongs to the field of auxiliary components of anchor rods, and particularly relates to a sleeve
assembly capable of improving the anti-shearing performance of an anchor rod and the anchor rod comprising thesleeve
assembly. The sleeve
assembly comprises a sleeve (2), the sleeve (2) is arranged at the inner side end, provided with a tray (4), of an anchor rod body (1), and an O-shaped sealing ring (3) is arranged between the sleeve (2) and the anchor rod body (1); the sleeve assembly further comprises an iron spacer (7) arranged at the outer side end of the tray (4) of the anchorrod body (1), a plastic
washer (6) and a ball pad (5), and a fixed damping nut (8) is arranged at the outer end of the ball pad (5). The whole design can effectively reduce the amount of anchor rod fracturing caused by staggering of holes and surrounding rock, improve the anti-shearing capacity of an anchor rod
supporting system, reduce cost of supplementary driving of anchor rods, reduce manuallabor of workers, improve the supporting effect of the anchor rods, and improve the safety ofroadway supporting.
