Abstract

Dispositif de fermeture d'un trou de forage destiné à l'injection de fluides appropriés, en particulier pour la consolidation des roches. Ce dispositif est caractérisé en ce que les douilles (3,4) recevant l'élément d'étanchéité (2) sont fabriquées en un matériau déformable élastiquement, la douille (3) qui est sitiuée à l'opposé du fond du trou de forage est montée coulissante sur le tube de remplissage (1) au moyen d'un manchon interne (8) et elle entoure l'élément d'étanchéité (2) au moyen d'une jupe annulaire (9), la douille fendue (4) qui est tournée vers le fond du trou de forage, est vissée sur le tube de remplissage (1) au moyen d'un taraudage (10) et, en combinaison avec une douille en forme de coin (14) engagée partiellement sous l'élément d'étanchéité (2), elle présente des languettes expansibles (12).Device for closing a borehole intended for injecting suitable fluids, in particular for consolidating rocks. This device is characterized in that the bushings (3,4) receiving the sealing element (2) are made of an elastically deformable material, the bushing (3) which is located opposite the bottom of the borehole is slidably mounted on the filling tube (1) by means of an internal sleeve (8) and it surrounds the sealing element (2) by means of an annular skirt (9), the split sleeve (4) which faces towards the bottom of the borehole, is screwed onto the filling tube (1) by means of a thread (10) and, in combination with a wedge-shaped bushing (14) partially engaged under the element sealing (2), it has expandable tongues (12).
