Abstract
A novel design and construction method for the creation of a Deployable Flexible Flood Mitigation Device manufactured from textile and membrane materials. The Flexible Flood Mitigation Device comprises a textile/membrane panel configured to be movable between an opened position and a closed position, wherein in the closed position, the panel forms a barrier against flood water; and a spool that is manually or electrically operated is used to move the panel from the closed position to the opened position. The spool can also be eliminated and the panel can be manually folded for storage. The Flexible Flood Mitigation Device can be configured for use in many applications including subway tunnels, vehicular tunnels, stairwells, ventilation shafts, and other openings that can be threatened by flooding. It can be used in any orientation (vertical, horizontal or at an angle with respect to gravity), and can stop fluids approaching from either side. It can also be shaped to fit any opening. Although its primary use is flood mitigation, the device is also applicable to containment of smoke from fire, chemical or biological agents, or other transient media.
