Title
(EN) PROCESS FOR REPAIRING STRUCTURES, OBJECTS, IN PARTICULAR SEWERS AND PIPES OF DEFECTIVE STABILITY AND WATERTIGHTNESS, WITHOUT DISMANTLING
(FR) PROCEDE POUR LA REPARATION SANS DEMONTAGE D'OUVRAGES D'ART, D'OBJETS, NOTAMMENT D'EGOUTS ET DE CANALISATIONS DEFECTUEUX AU NIVEAU DE LA STATIQUE ET DE LA RETENTION D'EAU
Abstract
(EN) Process for repairing sewers, pipes, structures, and accessible objects made of any type of basic material and of any shape, which are defective in particular as regards stability and watertightness, without dismantling. The process is characterized in that a gutter made on site and/or prefabricated, monolithic, or composed of a plurality of elements, and a floor part are arranged in the lower part of the sewer to be repaired, and that a waterproofing material containing, in the corresponding consistency and quality, a binder and/or an aggregate and/or an additive and/or an auxiliary material and/or water is applied to the other surfaces of the wall (1) of the sewer - allowance being made for dynamic requirements - followed advantageously by one or more layers of mortar (5). Cracks (2) and defects in the sewer and the cavities (2) surrounding the latter are filled with the material (3).
(FR) Procédé pour la réparation sans démontage d'égouts, canalisations, ouvrages, objets accessibles en n'importe quel matériau de base et de n'importe quel format, qui sont défectueux notamment au niveau de la statique et de la rétention d'eau. Le procédé est caractérisé en ce que dans la partie inférieure de l'égout à réparer est disposée une cunette (4) réalisée sur place et/ou préfabriquée, monolithique ou constituée de plusieurs éléments, ainsi qu'une partie fond, et sur les autres surfaces de la paroi (1) d'égout, on applique, en tenant compte des exigences dynamiques, un matériau de rétention d'eau contenant, dans la consistance et la qualité correspondantes, un liant et/ou un granulat et/ou un additif et/ou un adjuvant et/ou un agrégat et/ou de l'eau, puis du mortier (5) gunité avantageusement en une ou plusieurs couches. Les fissures (2) et les zones défectueuses de l'égout ainsi que les cavités (2) tout autour de ce dernier sont comblées avec le matériau (3).
