Abstract

La présente invention concerne un étai anti-flexion destiné à être utilisé dans la construction d'une structure temporaire de retenue de terre. L'étai anti-flexion pour utilisation dans la construction d'une structure temporaire de retenue de terre selon la présente invention comporte: un étai disposé de façon à traverser une zone entre des parois retenant de la terre, qui se font face, et relié à des raidisseurs des parois retenant de la terre; des poutres diagonales installées de telle façon que des extrémités d'un côté soient reliées aux raidisseurs et que des extrémités de l'autre côté s'écartent vers chaque côté des extrémités longitudinales de l' étai; un élément de mise en tension installé sur le côté extérieur de l'étai; et un fil de mise en tension, qui est installé dans la direction longitudinale de l'étai et qui applique une tension aux élément de mise en tension de façon à compenser l'excentricité de l'étai. Selon la présente invention telle que décrite ci-dessus, la flexion de l'étai peut être empêchée en exerçant une tension en un point où la flexion de l'étai est prédite ou se produit, et la sûreté lors de la construction de la structure temporaire de retenue de terre peut ainsi avantageusement être assurée.
