A method of, and apparatus for, lining the interior surface (13) of a passageway (15) such as a pipeline, involving progressive installation of a liner (11) on the interior surface (13) of the passageway (15) or on a substrate applied to the interior surface of the passageway by adhesively bonding the liner (11) in position. The liner (11) is bonded to the inner surface (13) of the passageway (15), or onto a substrate applied to the inner surface of the passageway, using a substance which hardens and which together with the liner (11) forms a rigid structure. The apparatus (10) includes a body (23) adapted to be moved along the passageway (15) to progressively install the liner (11). The body (23) also applies the adhesive for the bonding process.

Cette invention se rapporte à un procédé et à un appareil servant à garnir la surface intérieure (13) d'un passage (15) tel qu'une canalisation, ce procédé consistant à installer progressivement un garnissage intérieur (11) sur la surface intérieure (13) du passage (15) ou sur un substrat appliqué sur la surface intérieure de ce passage, en collant le garnissage intérieur dans sa position par des moyens adhésifs. Le garnissage intérieur (15) est collé sur la surface interne (13) du passage ou sur un substrat appliqué sur la surface interne du passage, à l'aide d'une substance qui durcit et qui, avec le garnissage intérieur (11) forme une structure rigide. L'appareil (10) faisant l'objet de cette invention comprend un corps (23) conçu pour se déplacer le long du passage (15) de façon à y installer progressivement le garnissage intérieur. Ce corps (23) applique également l'adhésif de réalisation du processus de collage.
