Abstract
PURPOSE: To prevent the deformation of the cross section of a river by the falling of the rubberized cloth of a dam, i.g., the stagnation of water between the sealing sheet and the river bed, by providing a weep hole in the river bed in contact with the air and water-tight sheet.
CONSTITUTION: In the dam in which a flexible film bag 1 forming the dam is attached to the river bed on its upstream and downstream sides in a direction of crossing the river and then expended by sending a fluid into its inside so as to raise it, or shrunk by discharging the fluid from its inside so as to bring it down, at least one weep hole 9 is provided in the river bed in contact with water and air-tihgt sheet 2. From the weep hole 9, water stagnated between the air-tight sheet 2 and the river bed can be drawn out.
