A method for reinstating a pole standing in ground comprising, abutting an inner surface of a sleeve against an outer surface of the pole so as to have a lower portion of the sleeve penetrating the ground and an upper portion of the sleeve projecting above the ground, and sliding a secondary member against an outer surface of the sleeve so that the secondary member locates against the sleeve and projects above the ground and into the ground, wherein the construction is such that the sleeve and secondary member located against the sleeve jointly form a bridging beam incorporating a box section reinforcement of the bridging beam. The formation of this box section substantially improves the strength of the bridging beam above what would be expected from the strength of the individual components. |
