A pole arrangement comprising: - a pole (2) with a tubular external wall (4) of sheet metal; - a foundation (5) with a cavity (7) for receiving a lower section (8) of the external wall (4) of the pole; - a wedge element (6) for securing the pole in the cavity by wedging; and - a reinforcement element (23) mounted to a part of the section (8) of the external wall (4) of the pole received in the cavity, in order to counteract buckling of this part. The wedge element bears against the external wall of the pole through supporting projections, wherein there are free spaces be¬ tween the supporting projections in order to allow parts of the external wall of the pole to be pressed into some of these spaces when the external is buckled in connection with a collision. The reinforcement element (23) is arranged at an axial distance from an upper opening (9) of the cavity in order to allow, in connection with a collision against the pole, buckling of the part of the external wall of the pole located between the reinforcement element and the opening of the cavity. |
