Flex-Cover® Resilient Tunnel Plug
RTP
The Flex-Cover® Resilient Tunnel Plug is a high-strength inflatable device that rapidly deploys to prevent flooding in a tunnel of any shape or size. Similar to how an automobile airbag functions in that this device resides in a small container, you then pressurize it (either remotely or locally) to shape when a flooding event occurs. Internal pressure exceeds the external water pressure threat to create the barrier, and the plug is held in place with friction. The Resilient Tunnel Plug can also be used for other applications, including the prevention of flooding from top-down water events or to partition tunnels to prevent the movement of smoke, chemical/biological agents or people. It has been validated via testing in a 16.5-foot-diameter representative rail tunnel against a 30-foot water head pressure challenge.
The Resilient Tunnel Plug was developed under a Department of Homeland Security Science & Technology Directorate program. It was originally developed for security applications to protect underground subway systems from flooding caused by damage to an underwater transit tunnel. It consists of a custom designed, damage-tolerant plug, a container, an inflation system that monitors system health and controls pressure. It can be used as a fixed asset at point-of-use for a rapid response approach or as a transportable system that can be deployed to a location when needed.
