Abstract

Ce cadre de soutènement entièrement fermé pour galerie ou tunnel comprend une partie en U 1 à laquelle est raccordée une entretoise de sole rectiligne 2. Pour conférer au cadre la capacité de résister à la pression du terrain avec une entretoise de sole droite, on munit cette entretoise 2 de pattes 11 dirigées vers le haut, sur lesquelles les branches de la partie en U 1 s'articulent par des boulons 12. Les forces latérales 13 exercées par la pression du terrain sur les zones 9 du cadre sollicitent l'entretoise 2 en tendant à l'incurver vers le bas, ce qui rend cette entretoise capable de résister à une pression du terrain dirigée de bas en haut suivant la flèche 15.This fully closed support frame for gallery or tunnel comprises a U-shaped part 1 to which is connected a rectilinear sole spacer 2. To give the frame the capacity to withstand the pressure of the ground with a straight sole spacer, this is provided. spacer 2 of lugs 11 directed upwards, on which the branches of the U-shaped part 1 are articulated by bolts 12. The lateral forces 13 exerted by the pressure of the ground on the zones 9 of the frame stress the spacer 2 in tending to curve downwards, which makes this spacer capable of withstanding a pressure from the ground directed from the bottom upwards along the arrow 15.
