Fabric containment constructions
Abstract
Abstract A dual-wall fabric is provided, with integrally woven drop stitches connecting opposite walls thereof, the fabric being adapted to receive a filler material between walls thereof, the filler material being preferably cast therein, such as concrete, and the fabric walls being of desired materials and weaves to yield desired porosities. One or both of the walls may be constructed of a material having a specific gravity less than water, to facilitate floating of the same in water. Prior to filling the dual-wall fabric with concrete or the like, reinforcing rods may be interspersed between the connecting drop stitches. The dual-wall fabric, or a single-wall fabric may be anchored along beaches, canals and the like, into canopy-like configurations or structures, which structures may be filled with sand or other natural fill, the mound or sand bar thus formed being then covered by a concrete-like material. In the case of a dual-wall fabric construction, concrete may be pumped between the fabric walls, to provide a concrete-like outer encasement for the sand bar or the like thus formed.
