Abstract

L'invention concerne une structure de sol à pieux en acier permettant de construire avec stabilité divers types de structures, telles que des ponts et des murs de soutènement sur le sol, des édifices sur l'eau et des logements, les pieux en acier dotés d'une résistance aux vibrations étant enfouis dans le sous-sol comme des arbres. Dans un mode de réalisation, une structure de pont comprend : un pieu en acier fixé avec au moins deux nervures dans le sens radial en dehors de la partie extrémité avant d'un tuyau en acier de forme cylindrique creuse, et une plaque d'extension en forme d'anneau présentant un diamètre plus grand que le tuyau d'acier sur les surfaces inférieures des nervures ; une poutre de support de poutre maîtresse empilée sur le pieu en acier ; une poutre composite empilée sur la poutre de support de poutre maîtresse et constituée d'une première poutre, d'une deuxième poutre empilée sur la première et de plaques de raccordement chevauchant les deux parties extrémité inférieure de la première poutre et les deux parties extrémité supérieure de la deuxième poutre ; et une plaque de plancher empilée sur la poutre composite. Le pieu en acier selon l'invention est fixé et soutenu par du béton mélangé à un adjuvant anti-corrosion, dans le trou foré dans le sol. La poutre composite est couplée par des boulons qui pénètrent dans la première et dans la deuxième poutre et dans les plaques de raccordement chevauchantes.
