摘要： A sluice gate including a closure member (5) comprising a sheet (6) of flexible fabric reinforced polymeric material having pairs of reinforcing members (8, 9) extending horizontally across the sheet (6) with one member of each pair located on the upstream side and the other on the downstream side of the sheet (6) in use. The pairs of members (8, 9) are secured together with the flexible sheet (6) between them and at least some of the members (8) on the upstream side extend beyond the side edges of the sluice opening (2) to be controlled and those (9) on the downstream side are able to pass into the sluice opening (2). The sluice gate includes control means (12, 13) for drawing the lower end of the closure member (5) upwardly and away from the opening (2) to progressively open it and to allow the closure member (5) to return progressively to the closed position.
