Abstract
PURPOSE: To enable constant maintaining of a planned water level by use of a bag weir body which can control the weir body position by the fluid amount fed in the bag.
CONSTITUTION: When the upstream water level has reached a first water level 1, a butterfly valve 12 opens, and the fluid corresponding to the pressure difference between the pressure in the weir body formed by feeding the fluid in a bag 4 and the head of that length of a water seal pipe 15 which is in water is discharged through the pipe 15 until the pressure difference is nulified. At a second water level 2, the above-said actions are repeated by a butterfly valve 22 and a water seal pipe 25. When a third water level 3 which is the automatic fall water level has been reached, a butterfly valve 32 opens and the fluid in the weir body is completely discharged through a pipe 81 so that the weir falls down.
