Multi-ribbed geotextile tubes and segments thereof

摘要

A large scale geotextile tube includes a plurality of cylindrical geotextile segments permanently connected end-to-end via circumferential ribs. In one embodiment, each geotextile segment is formed of the sheet of geotextile fabric that has an overlapping region that measures at least 5% of the elongation at break length of the sheet and permanently connected with at least one transverse rib to form an axial closure.

主权项

1. A hollow, generally cylindrically-shaped geotextile segment for forming a geotextile tube, the geotextile segment having a circumference of at least six meters, the hollow geotextile segment comprising:
a sheet of woven geotextile fabric, the fabric being defined by a plurality of spaced apart warp yarns extending parallel to each other and a plurality of spaced apart weft yarns extending parallel to each other and normal to the warp yarns, the sheet of geotextile fabric being substantially shaped as a parallelogram that is defined by opposed long side edges that are parallel to each other and by opposed short side edges, each of the long side edges being longer in length than each of the short side edges, a first narrow end section of the sheet of geotextile fabric terminating in a first one of the short side edges, a second narrow end section of the sheet of geotextile fabric terminating in a second one of the short side edges, the first narrow end section of the sheet of geotextile fabric being overlapped on the second narrow end section of the sheet of geotextile fabric to define an overlapping region of the hollow geotextile segment and rendering the geotextile segment capable of forming a continuous cylindrical shape having a circumference thereof and having an opening at each opposite end of the geotextile segment, each of the openings being defined by a respective one of the long side edges of the sheet of geotextile fabric and having a central longitudinal axis defining the axial direction and extending through both openings, and the first narrow end section of the sheet of geotextile fabric being permanently connected to the second narrow end section of the sheet of geotextile fabric by at least one transverse rib that defines an elongated region of attachment that permanently connects the sheet of geotextile fabric to itself in the overlapping region of the first and second narrow end sections of the sheet of geotextile fabric to form an axial closure of the geotextile segment, wherein the axial closure elongates in the axial direction, wherein the at least one transverse rib elongates in a direction that is not parallel to the central longitudinal axis and so that the at least one transverse rib extends across at least one of the short side edges of one of the respective narrow end sections of the sheet of geotextile fabric, and wherein the at least one transverse rib does not extend completely around the circumference of the geotextile segment.
