(FR)Lorsqu'on sépare par découpage la paroi latérale d'une cuve de stockage cylindrique de son fond, et qu'on découpe cette paroi en spirale depuis son bas vers son sommet pour l'éliminer par morceaux, l'invention permet de supporter temporairement ce bas de paroi latérale tout en l'abaissant progressivement vers le point de découpe au fur et à mesure que cette élimination progresse. Grâce à l'invention, ce travail se révèle sûr et peu onéreux, et il peut intervenir même au milieu d'autres structures. De plus, il peut se faire facilement et sans recours à un support tournant destiné à faire pivoter le haut de la cuve de stockage.
