A fluid-fillable barrier which includes a flexible, tubular, impermeable membrane and at least two internal tension members. The membrane has opposite ends, a middle, fluid-fillable section, an upper attachment area, and a lower attachment area. The tension members secure between, and extend from, the upper attachment area to the lower attachment area. The tension members have a length which is less than one-half the perimeter of the membrane, the length and perimeter being measured at a common cross-section, taken perpendicular to a longitudinal axis of the membrane. One of the tension members is longer than the other, so that it is in a relaxed, limp state under normal operating conditions. The tension members are thermally bonded to, and sewn with a double sew line to, the attachment areas. The barrier further includes lifting loops at each end, connection cleats on the sides and ends, and venting/drainage standpipes. |

1. A method of manufacturing a fluid-fillable barrier, the fluid-fillable barrier comprising a tubular impermeable membrane having a longitudinal axis, opposite ends at first and second ends of the longitudinal axis, a middle, fluid-fillable portion, a first attachment area on a first side of the longitudinal axis, and a second attachment area on a second side of the longitudinal axis, the second side opposing the first side, comprising the steps of:
thermally bonding ends of a first tension member to the attachment areas; sewing the ends of the first tension member to the attachment areas to form a thermally-bonded and sewn connection; and repeating the steps of thermally bonding and sewing for a second tension member;wherein the step of sewing includes sewing a double sew line. |
