A concrete reinforcement gridwork (16,17) is supported on the lower frame. After erection in a ground hole, concrete is poured into the hole to a fill plane defined by the upper frame member (14) so as to embed the frame member and gridwork and a portion of the guide rods located below the fill plane.
