Fluid-Fillable Barrier

摘要

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 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; a first tension member extending from the first attachment area to the second attachment area; a second tension member extending from the first attachment area to the second attachment area; and the tension members each having at least one hole to equalize fluid pressure on either side of the tension member; wherein, when the barrier is filled with fluid, and is in a place to block a fluid, the first tension member prevents the barrier from being moved from the place by external fluid pressure, and wherein the first tension member has a taut length which is less than one-half of the taut perimeter of a cross-section of the tubular membrane, the taut length and the taut perimeter being measured at a common cross-section taken perpendicular to a longitudinal axis of the tubular membrane, and wherein the length of the second tension member, in a relaxed state, is at least one inch longer than the taut length of the first tension member.
