摘要：
A rubber sheet (12) is formed in a bag shape, and a seam portion (12A) of the bag-shaped rubber sheet is fixed to a summit portion of an overflow dam (14). When the bag-shaped rubber sheet is expanded, a rubber dam is raised, thereby damming up water and adjusting the amount of running water. Next, when the bag-shaped rubber sheet (12) which has been expanded is contracted and collapsed, the rubber sheet (12) is supported by pipes (40), which extend substantially horizontally from the summit portion (14A) of the overflow dam toward the downstream side at a predetermined distance from each other. For this reason, the rubber sheet hangs down with its own weight and with the weight of water running downstream so as to droop down between the pipes. As a result, a rubber dam that does not bulge at the downstream side is obtained.
