Abstract

L'invention concerne un procédé permettant de rénover des canalisations. Les dépôts situés à l'intérieur des canalisations sont éliminés par des agents abrasifs en écoulement et l'intérieur des canalisations ainsi traitées est ensuite recouvert d'un matériau de revêtement visqueux durcissable. Afin de parvenir à une qualité de conduction comparable à celle de canalisations neuves, tout en utilisant des moyens techniques simples et en évitant des phénomènes d'obstruction dus à des dépôts intérieurs décollés, pendant le traitement, le procédé se déroule de manière à ce que l'agent abrasif soit introduit dans la conduite sous l'effet d'une chute de pression, qu'il y effectue un mouvement de va-et-vient sous l'effet d'une différence de pression alternée et qu'il en soit finalement ressorti, sous l'effet de la différence de pression entre les deux extrémités de la conduite.
