Abstract

PURPOSE: To prepare barrage possible to get under automatical control by providing airtight bag between base and steel plate, the latter of which is jointed at its lowest end in a rotation-free way with the base laid at the bottom of river etc., making the bag's engagement metal fittings matched with play with bag holes made in given numbers in both steel plate and base in order to prevent vibration and damage of the bag.
CONSTITUTION: When pressure is applied by air into empty bag 3, the bag 3 swells against water pressure and pushes up steel plate 2 in a rotating way. So as for bag 3 to be free from excessive counterforce in this operation and surely push up steel plate 2, bag holes in required numbers are made in base 1 and steel plate 2 respectively, while engagement metal fittings in required numbers are provided on bag 3 in a projecting way in such a style that they can move freely in the long slit 6 made in bag hole 8 covered by watertight hood 7. Because bag 3 is connected with suitable freedom in such a way, it can afford to serve for regulation of over-flow of water in correspondence to the water level of upstream under proper pressure given to bag 3 by pressure-supplying device.
