CA 2159833

A laying or transporting apparatus includes a pipe (9) having a longitudinal slit (6) throughout the full length, a moving member (23) inserted into the pipe (9) and driven along it by compressed air fed into the pipe (9), and a connecting member (1) that consists of a wire passing through the slit and connected at its inner end to the moving member (23) inside the pipe and at its outer end to a material (15) to be laid. A wire material (8) for sealing, which can close the slit (6), is disposed inside the pipe (9) throughout its full length, and a guide groove (7) for guiding the sealing wire material (8) in such a manner as to close the slit (6) at the time of movement of the moving member (23) is preferably provided on the moving member (23). The laying operation can be carried out by a smaller number of workers and the laying time can be reduced much more drastically that in the prior art apparatuses. The laying operation can be carried out efficiently and safely even at a high place, a complicated place or a course.

La présente invention concerne un appareil de pose ou de transport comprenant un tuyau (9) présentant une fente (6) longitudinale sur toute la longueur, un élément de mobile (23) inséré dans le tuyau (9) et entraîné dans celui-ci par de l'air comprimé introduit dans ledit tuyau (9), et un élément de connexion (1) consistant en un fil passant par la fente et relié par son extrémité interne à l'élément mobile (23) situé à l'intérieur dudit tuyau et par son extrémité externe au produit (15) à poser. Un fil de fermeture (8), qui peut obturer la fente (6), est disposé à l'intérieur du tuyau sur toute sa longueur, et il est préférable de prévoir sur l'élément (23) une rainure (7) servant à guider le fil de fermeture (8) de manière à obturer la fente (6) lors de l'entrée en mouvement de l'élément mobile (23); on peut ainsi effectuer l'opération de pose avec moins d'ouvriers et réduire beaucoup plus le temps de pose que ne le permettent les appareils actuels. L'opération de pose peut s'effectuer dans des conditions d'efficacité et de sécurité, même en un endroit élevé, compliqué d'accès ou sur un parcours.
