Title
(DE) VERFAHREN ZUM VORSPANNEN EINES TURMS EINER WINDENERGIEANLAGE
(EN) METHOD FOR PRETENSIONING A TOWER OF A WIND POWER PLANT
(FR) PROCÉDÉ POUR RÉALISER UN PRÉSERRAGE DU MÂT D'UNE ÉOLIENNE
Abstract
(DE)
Die Erfindung betrifft ein Verfahren zum Vorspannen eines Turms (102) einer Windenergieanlage (100), umfassend die Schritte: Bereitstellen einer Spannvorrichtung (300) mit einem Adapterelement (2020) und/oder einer Fundamentanordnung (200) und einem Spannelement (303) und/oder eines Adapterelements (2020) und/oder einer Fundamentanordnung (200) Befestigen eines unteren Endes eines Spannelements (303) an einer Befestigungseinrichtung (2021) des Adapterelements (2020), Befestigen eines oberen Endes eines Spannelements (303) an einem oberen Ende des Turms (102), Spannen des Spannelements (303) am unteren Ende des Spannelements (303) und/oder am oberen Ende des Spannelements (303),dadurch gekennzeichnet, dass das Spannen des Spannelements (303) durch Verkleinerung eines lichten Abstands zwischen dem Fundament (201) und dem Adapterelement (2020) erfolgt.
(EN)
The invention relates to a method for pretensioning a tower (102) of a wind power plant (100), comprising the steps: providing a tensioning apparatus (300) having an adapter element (2020) and/or a foundation assembly (200) and a tensioning element (303) and/or an adapter element (2020) and/or a foundation assembly (200); fastening a lower end of a tensioning element (303) to a fastening unit (2021) of the adapter element (2020); fastening an upper end of a tensioning element (303) to an upper end of the tower (102); and tensioning the tensioning element (303) at the lower end of the tensioning element (303) and/or at the upper end of the tensioning element (303); characterised in that the tensioning element (303) is tensioned by reducing the clear distance between the foundation (201) and the adapter element (2020).
(FR)
L'invention concerne un procédé pour réaliser un préserrage du mât (102) d'une éolienne (100), comprenant les étapes consistant à : fournir un dispositif de serrage (300) doté d'un élément d'adaptation (2020) et/ou d'un système de fondation (200) et d'un élément de serrage (303) et/ou d'un élément d'adaptation (2020) et/ou d'un système de fondation (200) ; fixer une extrémité inférieure d'un élément de serrage (303) à un dispositif de fixation (2021) de l'élément d'adaptation (2020) ; fixer une extrémité supérieure d'un élément de serrage (303) à une extrémité supérieure du mât (102) ; serrer l'élément de serrage (303) à l'extrémité inférieure de l'élément de serrage (303) et/ou à l'extrémité supérieure de l'élément de serrage (303). L'invention est caractérisée en ce que le serrage de l'élément de serrage (303) s'effectue par diminution de l'espace intérieure entre la fondation (201) et l'élément d’adaptation (2020).
