Abstract

The temporary barrage comprises a flexible membrane (14) spanning horizontally between closely spaced vertical counterfort frames (12), and may be used to dam rivers or canals etc. When loaded by retained water the membrane (14) adopts outwardly deflected curved bays between frames (12), and is specially fabricated to obtain semi-circular inter frame deflected profiles. The arrangement obtains uniformity of loading on both the membrane and the frames. The membrane has 'U' section border pieces (22, 24) running continuously along the top and bottom horizontal edges. The edges of the main body of the membrane are fixed in the hems or border pieces (22, 24) and the length of the membrane (14) is greater than that of the hems. The ratio of hem length to membrane length is 2:Pi and the additional length of membrane is taken up by double folding at frame centres. The membrane may also include a sealing apron (28).
