Abstract

The collapsible rubber dam is secured to a river bed (15) and slope portions (16) of both riverbanks. It is inflated and deflated by supply and discharge of a fluid. A pipe for supply and discharge of fluid communicates with the inside of the rubber dam from the slope portion of at least one riverbank. The pipe for supply and discharge of the fluid is located in a region (ABD). This is defined by the top end (A) of the rubber dam located in the slope portion, the middle position (D) of the deflated width of the rubber dam at the toe of the slope portion, and a securing position (B) of the rubber dam at the toe of the slope portion.
