Abstract

Dispositif de jonction de tuyaux emboîtés. La surface interne de l'extrémité ouverte de la partie femelle 1 dans laquelle est emboîtée l'extrémité mâle 2 d'un autre tuyau comprend une gorge annulaire 13 et une butée 3 destinée à arrêter un élément d'étanchéité 5. Une bague de verrouillage fendue 16 est disposée dans la gorge annulaire 13. La surface périphérique de l'extrémité mâle comprend une saillie 14 disposée entre la bague 16 et la butée et qui peut se déplacer axialement entre elles de façon à porter contre elles aux extrémités de sa course. Un élément 17 qui empêche l'expansion radiale de la bague 16 est interposé entre le fond de la gorge annulaire 13 et la surface périphérique de celle-ci. Application à la jonction de tuyaux emboîtes qui doivent être installés dans un tuyau déjà existant ou dans un trou forcé dans le soLDevice for connecting nested pipes. The internal surface of the open end of the female part 1 in which is fitted the male end 2 of another pipe comprises an annular groove 13 and a stop 3 intended to stop a sealing element 5. A locking ring slotted 16 is disposed in the annular groove 13. The peripheral surface of the male end comprises a projection 14 disposed between the ring 16 and the stop and which can move axially between them so as to bear against them at the ends of its stroke. An element 17 which prevents the radial expansion of the ring 16 is interposed between the bottom of the annular groove 13 and the peripheral surface thereof. Application to the junction of socket pipes which must be installed in an already existing pipe or in a forced hole in the ground
