Title
(EN) UNDERGROUND AND PARTLY SUBMERGED PIPE WINDING APPARATUS AND METHOD
(FR) APPAREIL ET PROCEDE D'ENROULEMENT DE TUYAU SOUTERRAIN ET PARTIELLEMENT IMMERGE
Abstract
(EN)
An apparatus and method for lining an underground conduit is disclosed. The apparatus (10) comprises: an annular frame (40) having a crown portion (42) and a base portion (49); a strip guide disposed around and supported by the annular frame (40), the guide arranged to guide a strip (12) around a helical path; a pair of strip pinch rollers mounted to the frame (40) at a position circumf erentially about halfway between the crown portion (42) and the base portion (49); a drive assembly mounted to the frame for driving the strip (12) downwards into the helical path in a winding direction so as to present an incoming first edge to an adjacent second edge of a wound convolution of the strip; a liquid remover mounted to the frame, the liquid remover arranged to prevent liquid that has adhered to and ascended with the second edge from descending down towards the incoming first edge; and an extruder (80) mounted to the frame (40) for extruding a molten bead of plastic onto the strip (12) at a position just before said overlap.

L'invention concerne un appareil et un procédé de revêtement d'un conduit souterrain. L'appareil (10) comprend : un cadre annulaire (40) ayant une partie couronne (42) et une partie base (49) ; un guide bande entourant le cadre annulaire (40) et supporté par ce dernier, et disposé pour guider une bande (12) autour d'un trajet hélicoïdal ; une paire de rouleaux pinceurs de bande montés sur le cadre (40) dans une position circonférentielle environ à mi-chemin entre la partie couronne (42) et la partie base (49) ; un ensemble d'entraînement monté sur le cadre pour entraîner la bande (12) vers le bas dans le trajet hélicoïdal dans le sens d'enroulement pour présenter un premier bord arrivant à un second bord adjacent d'une circonvolution de la bande ; un dispositif de retrait de liquide monté sur le cadre, et disposé pour empêcher le liquide resté collé sur le second bord et ayant monté avec celui-ci, de descendre vers le premier bord arrivant ; et une extrudeuse (80) montée sur le cadre (40) afin d extruder un cordon de plastique en fusion sur la bande (12) dans une position située juste avant ledit chevauchement.
