Abstract

The multiple panel lining system is positioned adjacent to and supported by an inclined support surface. A horizontally extending support cable is positioned adjacent to the inclined support surface. Each of a plurality of spaced apart anchors is secured to the inclined support surface and to the support cable to maintain the support cable at a fixed vertical elevation and to transfer loads imposed on the support cable to the inclined support surface. A series of foldable panels with an open mesh network are draped over and supported from above by the support cable. Each panel includes an inner layer which contacts the inclined surface and an outer layer which is placed above and overlaps the inner layer. A first sealant layer is applied to and supported by the mesh network of the inner layer of the panel. A second sealant layer is applied to and supported by the mesh network of the outer layer of the panel and by the first sealant layer. A series of stress absorbing joints are formed within vertical overlap zones between laterally adjacent panels. A series of stress absorbing joints are formed within horizontal overlap zones between vertically adjacent panels.
