GROUTING PRESTRESSING DUCTS OF THE SAINT CLOUD VIADUCT

INJECTIONS DES GAINES DE PRECONTRAINTE DU VIADUC DE SAINT CLOUD

THE BRIDGE DECK IS PRESTRESSED IN THREE DIRECTIONS BY FREYSSINET CABLES (83 KM OF STUP 12 T13 AND 28 KM OF STUP 127). THE CABLES ARE SEPARATED IN THREE GROUPS DIFFERING BY THEIR LOCATION AND THE AMOUNT OF GROUT NECESSARY TO INJECT THEM. CABLE BY CABLE GROUTING WAS IMPOSSIBLE BECAUSE THE JOINTS WERE NOT IMPERVIOUS TO WATER, EACH GROUP OF CABLES WAS THEREFORE GROUTED AS ONE UNIT. THE USE OF TRADITIONAL GROUT WAS NOT POSSIBLE. A RETARDED GROUT WAS USED. THE ARTICLE GIVES THE COMPOSITION OF THIS GROUT AND DESCRIBES THE EQUIPMENT USED ON SITE TO CARRY OUT THE GROUTING OPERATION.
