Abstract

Obturateur pour l'injection de ciment ou de produits de consolidation. Appareil composé d'une manchette gonflable et d'un manchon protecteur rétractable. En effet, pour se dilater, la manchette doit se raccourcir en ayant une partie coulissante étanche qui, si elle n'est pas protégée, sera au contact du produit, bloquant ainsi la translation lors du dégonflage, empechant la récupération de l'appareil. Pour pallier à cet inconvénient, on insère entre la partie coulissante associée à la manchette 2 et l'extrémité de la tige d'injection 1 un manchon 3 en matière élastique qui protège la tige et joue le rôle de ressort de rappel lors du dégonflage.
