Abstract

PURPOSE: To prevent damage such as perforation on bag body namely weir membrane of movable weir which will be made on creased part due to repeated bending fatigue, while creases, liable to generate on weir membrane when weir expands, is minimized.
CONSTITUTION: Bag body 4 and flexible membrane 7, 8 are provided. Bag body 4 is established only on a riverbed, not at the riverside embankment, and it functions so as to maintain weir shape and its height, while the flexible membrane 7, 8, separate from the bag body 4, purports to intercept water, being attached on the riverside embankment on the upstream or the downstream of the river. When the bag body 4 is inflated and weir is formulated, the membrane 7, 8 cover the weir from the riverbed up to the top of the weir and function as water interceptor being located between the river embankment and the bag body 4.
