A method of manufacturing a multifunction utility pole comprising providing a mold having a base portion and a pole portion, the base portion containing an internal cavity sized and shaped to receive a housing; installing the housing in the internal cavity; installing reinforcing cables extending from the base portion to the pole portion, the reinforcing cables being offset around the housing in the base portion; installing a conduit, the conduit being electrically isolated from the housing; pouring flowable concrete into the mold; closing the mold; prestressing the reinforcing cables; spinning the mold for a predetermined time until the concrete takes the shape of the mold; and removing the mold.

L'invention concerne la méthode de fabrication d'un poteau polyvalent pour services publics au moyen d'un moule constitué d'une portion supérieure et d'une base. La base contient une cavité centrale et sa forme est prévue pour qu'on y insère et installe un boîtier. Des câbles de renforcement sont installés dans le poteau et courent de l'extrémité inférieure de la base à l'extrémité supérieure du poteau. Fait à noter, dans la base, les câbles de renforcement contournent le boîtier. Par la suite, on met en place un conduit électriquement isolé du boîtier, on coule du béton liquide dans le moule, on ferme le moule, on exerce une contrainte sur les câbles de renforcement, on attend pendant la période nécessaire pour que le béton prenne solidement, puis il ne reste qu'à retirer le moule.
