Patent

CA 2391812

A pole support for ground poles, such as telephone poles and power poles, is disclosed. The support can be driven into the ground next to the pole. It has a pair of spaced apart longitudinal end plates (51, 52) which are interconnected intermediate their ends by an intermediate plate (53). The end plates are spaced apart to allow the ground pole to pass at least partially between the end plates. Each end plate has a front longitudinal edge (54, 55) which, in use, is adjacent to the pole and a rear longitudinal edge (56, 57) which, in use, is directed away from the pole. The pole support has means to reduce sharp edges on the rear longitudinal edges. Also disclosed is a method for testing pole strength which comprises applying a load to the pole and either measuring its displacement or observing if it withstands the load. The amount of load applied to the pole and the degree of displacement it undergoes can be used to calculate the residual strength of the pole.

L'invention concerne un support de poteaux pour des poteaux de terre, tels que les poteaux de téléphone et les colonnes d'alimentation. Le support peut être installé dans le sol à proximité du poteau. Il présente une paire de plaques terminales (51, 52) longitudinales espacées interconnectées entre leurs extrémités par une plaque intermédiaire (53). Ces plaques terminales sont espacées de manière à permettre au poteau de terre de passer au moins partiellement entre les plaques terminales, chacune comprenant un bord avant longitudinal (54, 55) adjacent au poteau et un bord arrière longitudinal (56, 57) éloigné du poteau. Le support présente des moyens permettant de réduire les bords tranchants sur les bords arrière longitudinaux. Fait aussi l'objet de cette invention un procédé de test de la résistance d'un poteau consistant à appliquer une charge sur le poteau et à mesurer son déplacement ou à observer s'il la supporte. La quantité de charge appliquée au poteau et le degré de déplacement de ce dernier peuvent servir à calculer la résistance résiduelle du poteau.
