Abstract

L’invention concerne un ancrage de mise à la terre soutenant et immobilisant un poteau électrique, ainsi que son procédé de construction. L’invention concerne notamment un procédé de construction utilisant une grue tarière pour réaliser un processus d’excavation consistant à effectuer une première excavation en pente, ou, selon le terrain, une première excavation en pente suivie d’une deuxième excavation verticale. Un piquet de mise à la terre connecté à un ancrage de mise à la terre est ensuite relié et fixé à un poteau électrique vertical par des câbles en acier. Selon l’invention, la simplification du processus d’excavation permet de réduire la main-d’œuvre et la durée des travaux. Le piquet de mise à terre et l’ancrage de mise à la terre sont solidement maintenus à angle droit, ce qui permet d’augmenter sensiblement la force de soutien et d’éviter l’inclinaison du poteau électrique ou les vices de construction. L’invention permet en outre d’améliorer l’environnement de travail et d’éviter les désagréments liés aux problèmes de circulation. La qualité améliorée de la construction permet d’assurer une meilleure protection vis-à-vis des intempéries du fait du soutien renforcé, et donc d’assurer une distribution stable et ininterrompue de l’électricité.
