ABSTRACT:
A sealing arrangement primarily for a sluice gate which comprises a frame and a door movable between an open position and a closed position in which it closes an opening in the frame and sealing faces of the door and the frame are in sealing engagement to prevent the flow of liquid through the opening. The sealing arrangement comprises an intermediate wedge section strip interposed between two side strips having inclined planar faces in contact with the inclined planar side faces of the intermediate strip. The intermediate strip is either arranged to bear against the door or secured to the frame, and either one of the side strips is secured to the frame or both side strips are arranged to bear against the door respectively. Adjusting means, for example a series of bolts and nuts, extend through apertures in the three strips and are operable to apply forces to the side strips to press them inwardly towards the intermediate strip thereby to cause either the intermediate strip or the two side strips to move relative to the fixed side strips or the fixed intermediate strip, respectively, under the effect of their co-operating inclined faces whereby the door is urged towards the frame and the sealing face of the door is pressed into sealing engagement with the sealing face of the frame.
