Abstract
A cellular confinement system for soil, sand or other filler material comprises a number of sub-assemblies each made up of a plurality of interconnected open cells of fabric material. The sub-assemblies are stackable one on top of the other to provide a structure having at least one generally vertical side or end wall. Each sub-assembly comprises a skirt portion which is arranged to overlap between vertically juxtaposed sub-assemblies in use. The skirt portion substantially prevents or minimises the escape of finer aggregate material from between the stacked sub-assemblies.
Claims20
A sub-assembly for a cellular confinement system for soil, sand or other filler material, the sub-assembly formed of a plurality of interconnected open cells of fabric material, wherein at least some of the cells are provided with a skirt portion extending from one or more respective walls of the cells, said skirt portion being integral with the one or more respective walls and comprising a skirting strip around an outer perimeter of the sub-assembly.
A sub-assembly for a cellular confinement system for soil, sand or other filler material, the sub-assembly formed of a plurality of interconnected cells of fabric material manufactured in at least one discrete cellular section, and comprising a wider piece of fabric around the perimeter of the cellular section to form perimeter walls for the cells with an integral skirt portion.
A sub-assembly for a cellular confinement system for soil, sand or other filler material, the sub-assembly formed of a plurality of interconnected open cells of flexible fabric material having a generally triangular shape.
A frameless cellular confinement system for soil, sand or other filler material, the system comprising one or more sub-assemblies formed of a plurality of interconnected open cells of fabric material, the sub-assemblies being stackable one on top of the other to provide a structure having at least one generally vertical side or end wall, wherein the cells have perimeter walls provided with a skirt portion that is integral with the perimeter walls and arranged between vertically juxtaposed sub-assemblies in use to substantially prevent or minimise finer aggregate material escaping from between the stacked sub-assemblies at said generally vertical side or end wall.
