(FR) APPAREIL POUR FAIRE SAUTER UN OBJET MOBILE D"UN POINT A UN AUTRE ET SON PROCEDE D"UTILISATION
Abstract: front page image
(EN)An apparatus (2 or 3) for jumping a moving object (10) from one place to another. Fields of application include protection of submarine installations such as pipelines (1) and cables, from damage due to dragging anchors (10) and fishing gear. The apparatus comprises a plate-like device (2 or 3) that is unstable with regard to a horizontal force over a certain strength. The deformation of the device (2 or 3) caused by such horizontal force results in a steeper direction of the resultant (14) acting on the edge (6). The frictional resistance combined with the passive soil pressure (7) thereby become able to withstand the horizontal force from the moving object (10). Subsequently the device (2 or 3) carrying the object (10) will turn around the edge (6) and thereby lift the object (10) over the installation (1). Several alternative designs of the device (2 or 3) and a method of installing it are disclosed.
(FR)Appareil (2 ou 3) destine a faire sauter un objet mobile (10) d"un endroit a un autre. Les domaines d"application comprennent la protection d"installations sous-marines telles que les pipelines (1) et les cables, contre les degats provoques par le derapage d"ancres (10) et attirails de peche. L"appareil comprend un dispositif en forme de plaques (2 ou 3) qui est stable par rapport a une force horizontale sur une certaine plage de resistance. La deformation du dispositif (2 ou 3) due a cette force horizontale se traduit par une direction plus abrupte de la resultante (14) agissant sur le bord (6). La resistance de friction combinee a la pression passive du sol (7) est alors capable de supporter la force horizontale de l"objet mobile (10). Par consequent, le dispositif (2 ou 3) portant l"objet (10) tournera autour du bord (6) et soulevera l"objet (10) par dessus l"installation (1). Plusieurs autres conceptions du dispositif (2 ou 3) et un procede d"installation sont decrits.
