Abstract

La présente invention concerne un élément de contreventement inférieur pour un poteau arqué des services publics. Ledit élément de contreventement est utilisé pour ériger fermement un poteau des services publics. L'élément de contreventement inférieur pour un poteau arqué des services publics de la présente invention est moulé en utilisant juste du béton conducteur et du béton général car la couche de béton conducteur disposée dans la partie inférieure de l'élément de contreventement inférieur pour un poteau arqué des services publics est mélangée avec des fragments métalliques durant le moulage. La couche de béton conducteur est reliée à l'acier d'armature dans l'élément de contreventement inférieur de poteau des services publics, et un fil conducteur supplémentaire est connecté à l'acier d'armature. Donc, l'installation d'automatisation pour un élément de contreventement inférieur existant pour un poteau arqué des services publics peut être appliquée sans changement et donc l'élément de contreventement inférieur de poteau des services publics de la présente invention peut être approprié pour la fabrication en masse, et le taux d'erreur de l'élément de contreventement inférieur de poteau des services publics de la présente invention peut être proche de zéro et donc l'élément de contreventement inférieur de poteau des services publics peut être très économique. Les fragments métalliques dans la couche de béton conducteur augmentent en outre le rendement de mise à la terre dans la couche de béton conducteur en présentant l'effet de réduction de la résistance élevée de mise à la terre, et le rendement de mise à la terre peut augmenter tandis que les coûts de fabrication peuvent être réduits même sans utiliser de plaque de terre coûteuse car le fil conducteur est soudé directement à l'acier d'armature épais.
