Abstract

L'invention concerne une structure d'étanchéité de joint circonférentiel d'une galerie de conduite intégrée souterraine. La structure d'étanchéité comprend un joint d'étanchéité circonférentiel (1), un joint d'étanchéité axial (2), une plaque de pression (3) et un boulon. Le joint d'étanchéité circonférentiel est disposé entre des bords pliés verticaux (51) de brides coudées en acier (5) de deux sections de galerie de conduite au niveau du joint circonférentiel. Les deux brides coudées en acier et le joint d'étanchéité circonférentiel sont pourvus d'un trou traversant de boulon, et un boulon passe à travers ce dernier pour relier les brides coudées en acier au joint d'étanchéité circonférentiel et pour les serrer sur ce dernier. Le joint d'étanchéité axial est disposé sur deux bords pliés axiaux (52) des brides coudées en acier parallèlement à un axe de la galerie de conduite. La plaque de pression est pressée sur le joint d'étanchéité axial. La plaque de pression et les bords pliés axiaux sont tous dotés d'un trou traversant de boulon, et un boulon passe à travers ce dernier pour relier la plaque de pression aux bords pliés axiaux, de façon à serrer le joint d'étanchéité axial. Le joint d'étanchéité axial peut être retiré et remplacé en cas de fuite de la structure d'étanchéité ou de défaillance du joint d'étanchéité, garantissant ainsi des effets de prévention durables contre une fuite au niveau du joint.
