Abstract

Pour former un trou traversant dans une plaque (2) d'amiante, on colle deux plaques (4) de matière plastique sur les surfaces opposées de la plaque d'amiante. Des ouvertures (6) pratiquées dans les plaques (4) sont alignées. Un récipient respectif (8) est supporté par chaque plaque (4) de telle façon que chaque ouverture (14) du récipient entoure la plaque (4). L'intérieur de chaque récipient (8) est relié à un aspirateur respectif (16) par l'intermédiaire d'un flexible (18). Lorsque les aspirateurs (16) ont été mis en marche, on fait passer un foret (24) dans un des récipients (8), et dans l'ouverture (6) de la plaque (4) respective pour le faire pénétrer dans la plaque d'amiante (2), et on commence à percer. La matière retirée de la plaque d'amiante (2) par le perçage pénètre dans les récipients (8) et est extraite par les aspirateurs (16) dans lesquels elle est recueillie. Une fois le perçage achevé, la surface intérieure du trou (28) réalisé peut être obturée ou garnie d'un revêtement.
