Title (EN) WIND TURBINE TOWER AND METHOD FOR BUILDING THE SAME
(FR) TOUR POUR ÉOLIENNE ET PROCÉDÉ POUR SA CONSTRUCTION
Abstract:
(EN) The present invention relates to a wind turbine tower and a method for building the same. The tower of the present invention comprises a platform and a number of columns "c", the platform resting upon the columns and receiving the wind turbine. Each column "c" of the tower comprises a foundation and a plurality of adjacent stacked column sections extending from the foundation. Each pair of adjacent column sections comprises a linking flange and a reinforcing element. The linking flange itself is characterized in that it comprises an edge, a main perforation traversing the flange and a satellite perforation traversing the flange, positioned between the edge and the main perforation. The present invention also pertains to a device for providing a seal around a main perforation of the flange during the construction of the tower. This device comprises a hollow body, an inlet for receiving building materials and a vent for allowing air circulation. The method for building the tower in accordance with the present invention does not require the use of lifting cranes to hoist the column sections on top of one another. The method may also be performed on the site of construction of the tower.
(FR) La présente invention concerne une tour pour éolienne et un procédé pour sa construction. La tour selon la présente invention comporte une plate-forme et un certain nombre de colonnes "c", la plate-forme reposant sur les colonnes et recevant l'éolienne. Chaque colonne "c" de la tour comporte une fondation et une pluralité de sections de colonne adjacentes superposées s'étendant à partir de la fondation. Chaque paire de sections de colonne adjacentes comporte une bride de liaison et un élément de renfort. La bride de liaison elle-même est caractérisée en ce qu'elle comporte un bord, une perforation principale traversant la bride et une perforation satellite traversant la bride, positionnée entre le bord et la perforation principale. La présente invention concerne également un dispositif destiné à assurer une étanchéité autour d'une perforation principale de la bride pendant la construction de la tour. Le dispositif en question comporte un corps creux, une entrée destinée à recevoir des matériaux de construction et un évent servant à permettre la circulation d'air. Le procédé de construction de la tour selon la présente invention ne nécessite pas l'utilisation de grues de levage pour hisser les sections de colonne les unes sur les autres. Le procédé peut également être mis en œuvre sur le site de construction de la tour.
