Reiforced anchoring-bolt

The utility model relates to a reenforced anchor pole, which is used for supporting the surrounding rock of an underground engineering and especially fits for an underground engineering support affected by the exploitation or an underground engineering support with the loose surrounding rock. The screw thread reinforcing steel bar is used to make an anchor pole body; the anchor tail of the anchor pole body is operated by the partial quenching, or quench tempering; or the anchor pole body is entirely operated by the quenching, but the anchor tail is operated by the low-temperature tempering or no tempering, and other parts of the anchor pole body are operated by the high-temperature tempering; the rigidity of the anchor tail is higher than that of other parts of the anchor pole body. The utility model has the advantages of high bearing capacity, high plasticity, and low cost.
