ABSTRACT:
A floodgate structure is disclosed for closing of an hydraulic flow channel at selected times, as during flooding conditions. A gate panel is normally loosely and slideably received in a recess below grade level. To render the gate operational, it is lifted into a channel-blocking position. Pneumatically inflatable peripheral sealing elements extend from the water side of the panel into sealing contact with a fixed support structure. The opposite side of the panel supports a flexible but noninflatable sealing skirt element, which is pressed into sealing contact with the supporting structure by expansion of the inflatable elements. When thus positioned, the sealing skirt becomes hydrostatically loaded by the pressure of the water and functions as an effective seal in the event of subsequent failure of the pneumatically expandable elements.
