Patent number: 6623214Abstract: An opening in a fabric geotextile tube is closed by clamping a backing member and friction enhancer on the inside of the geotextile tube to a friction enhancer and support on the outside of the geotextile tube. The friction enhancers reduce slippage between the fabric and the backing member on the inside of the tube and between the fabric and the support on the outside of the tube. The backing member is larger than the opening. In one embodiment, the backing member is inserted into the opening by providing a slit ring backing member, inserting the fabric through the slit and then rotating the ring and advancing the ring into the geotextile tube. In another embodiment, the backing member is inserted through the opening in segments. In another embodiment, an inlet assembly is provided by the support. In another embodiment of the invention, a connection is made to the geotextile tube for securing a UV protective cover to the geotextile tube.Type: GrantFiled: May 2, 2002Date of Patent: September 23, 2003Assignee: Shiner Moseley & Associates, Inc.Inventors: Gerald J.
