(FR) TAMPON ET PROCEDE D'INJECTION
Abstract:
(EN) A packer and a corresponding method for filling cracks in concrete structures with packing material pumped into the crack. The packer comprises a packer body (1) designed to be inserted into a hole (2) drilled in the structure to be repaired, said packer body having a part (8) with a conical outer surface and a seal (7) around the packer body; a fixing tube (13) which, when the packer is in the hole, protrudes out of the hole; and a check valve (6) in the packer body, located on the opposite side of the seal with respect to the fixing tube, which check valve opens into the hole and communicates with the outer end (4) of the fixing tube via a hole (5) going through the packer body and the fixing tube. According to the invention, the packer body and the fixing tube form a single, continuous cast integral body and the seal (7) consists of an elastic tube of constant circular cross section which can slide between and around the fixing tube and the conical part (8) of the packer body.
(FR) Ensemble d'étanchéité et procédé correspondant permettant de remplir des fissures dans des structures en béton avec un matériau d'étanchéité introduit par pompage dans la fissure. Cet ensemble d'étanchéité comprend un corps d'étanchéité (1) conçu pour être introduit dans un trou (2) percé dans la structure à réparer, ledit corps possédant une partie (8) comportant une surface extérieure conique et un joint (7) autour dudit corps; un tube de fixation (13) qui, lorsque l'ensemble d'étanchéité est dans le trou, forme une saillie hors du trou; un clapet de retenue (6) situé dans le corps du côté opposé au joint par rapport au tube de fixation, ledit clapet s'ouvrant vers l'intérieur du trou et communiquant avec l'extrémité extérieure (4) du tube de fixation par l'intermédiaire d'un passage (5) traversant le corps et le tube de fixation. D'après l'invention, le corps d'étanchéité et le tube de fixation constituent un corps unique continu moulé en un seul ensemble et le joint (7) consiste en un tube élastique présentant une section transversale circulaire constante pouvant coulisser entre le tube de fixation et la partie conique (8) dudit corps, ainsi qu'autour dudit tube et de ladite partie.
