Method for restoring civil engineering structures and other constructions, and devices for its implementation

The invention relates to a method for restoring a construction, and particularly a civil engineering structure, having, between constituent elements, one or more joints, at the locations of which it is advisable to establish or restore structural continuity. This method is characterised in that a temporary force of controlled value is first exerted in the plane of the joint 1 in question, so as to generate, take up or modify therein a prestressing of predetermined strength, after which, secondly, the joint is locked in the so-called "open" position, so as to provide a permanent replacement for the initially created temporary force which may then be relaxed. Application to civil engineering structures. L'INVENTION CONCERNE UN PROCEDE DE REHABILITATION D'UNE CONSTRUCTION ET NOTAMMENT D'UN OUVRAGE DE GENIE CIVIL PRESENTANT ENTRE ELEMENTS CONSTITUTIFS UN OU PLUSIEURS JOINTS AU DROIT DESQUELS IL CONVIENT D'ETABLIR OU DE RETABLIR UNE CONTINUITE DE STRUCTURE.CE PROCEDE EST CARACTERISE EN CE QU'ON EXERCE, DANS UN PREMIER TEMPS, UN EFFORT TEMPORAIRE DE GRANDEUR CONTROLEE DANS LE PLAN DU JOINT CONSIDERE 1, DE FACON A Y ENGENDRER REPRENDRE OU MODULER UNE PRECONTRAINTE A TAUX DETERMINE, APRES QUOI, DANS UN DEUXIEME TEMPS, ON BLOQUE LE JOINT EN POSITION DITE "OUVERTE", DE MANIERE A ASSURER UNE SUBSTITUTION PERMANENTE DE L'EFFORT TEMPORAIRE INITIALEMENT DEVELOPPE LEQUEL PEUT ALORS ETRE RELACHE.APPLICATION AUX OUVRAGES DE GENIE CIVIL.
