Abstract

Un système servant à l'introduction d'un câble (11) dans un tube gaine (12) pour câbles et en même temps à la pose souterraine du tube gaine (12) pour câbles contenant le câble (11) comprend un dispositif (43, 44) d'introduction en continu du câble dans le tube gaine (12), qui dans cette zone du système a une enveloppe ouverte d'un seul côté, et un dispositif servant au raccordement en continu des zones marginales opposées du tube gaine ouvert (12) après l'introduction du câble (11). Les zones marginales mutuellement opposées du tube gaine (12) pour câbles sont pourvues d'éléments d'emboîtement qui s'étendent sur toute la longueur du tube gaine et qui peuvent être rapprochées les unes des autres par le dispositif (51) de raccordement en continu jusqu'à ce qu'elles s'interpénètrent hermétiquement. Ainsi il n'est pas nécessaire que le tube gaine pour câbles, dans lequel un câble est introduit pendant sa pose, entoure complètement le câble et ledit tube gaine peut être directement posé sous terre alors que son intérieur est hermétiquement fermé.
