Abstract
PURPOSE: To provide movable weir of flexible membrane, e.g. rubber-impregnated fabric with bar-like element for separating overflowing water vein from the weir, and at the same time, prevent oscillation of the weir during overflow by supplying air into between the said separated water vein and the weir.
CONSTITUTION: Movable weir of flexible membrane is composed of bag-like element 1 of flexible membrane installed at the river bed in a direction of traversing a river and a pipe running through the said bag-like element 1, through which fluid such as air, etc. is sent to cause the weir to be inflated and stand upright. In addition, bar-like element 8 is mounted near the top of the said movable weir. In the meantime, water vein overflowing the movable weir 1 is separated from the membrance of the weir by the said bar-like element 8, creating air layer between the weir and the overflowing water vein. This air layer prevents oscillation of the weir caused by contact of the overflowing water vein with the weir membrance. In order to assure complete prevention of the weir oscillation, it is so designed as to supply air by means of blower, etc. through half-split portion of the bar-like element 8, etc.
