Abstract

La présente invention concerne un procédé de renforcement d'un ouvrage tel qu'une buse, comportant les étapes consistant à : - procéder à un relevé de la géométrie de l'ouvrage à renforcer, - réaliser au moins en fonction de ce relevé des anneaux de soutènement (10) de dimensions adaptées, chaque anneau de soutènement étant fermé par au moins un élément de liaison imposant un écartement ajustable entre deux régions adjacentes de l'anneau reliées par cet élément de liaison, - régler l'écartement entre lesdites régions adjacentes pour mettre en compression l'anneau au contact de l'ouvrage.The present invention relates to a method for reinforcing a structure such as a culvert, comprising the steps consisting of: - carrying out a survey of the geometry of the structure to be reinforced, - carrying out at least according to this survey rings retaining ring (10) of suitable dimensions, each retaining ring being closed by at least one connecting element imposing an adjustable spacing between two adjacent regions of the ring connected by this connecting element, - adjusting the spacing between said adjacent regions to compress the ring in contact with the work.
