Claims

[Scope of Claim for Utility Model Registration] (1) A flexible membrane bag forming a weir is attached to the river bank and river bed in a direction across the river, and a fluid as an expansion medium is fed into the bag to cause it to expand and rise. An undulating weir made of a flexible membrane, characterized in that the weir is configured to discharge fluid from the inside of the bag and cause the weir to contract and collapse, the weir having strength reinforcement applied to the membrane material at the weir's slope. (2) The same kind of membrane material as the cylindrical body part membrane material of the weir is used for the weir's weir's weir's weir's cylindrical body membrane material, and the former is laminated more than the latter, thereby reinforcing the strength of the weir's weir's weir's weir's weir's weir's weir's weir's strength has been registered as a utility model. An undulating weir made of a flexible membrane according to claim (1). (3) Utility model registration claimed in paragraph (1), in which the strength of the weir's weir's weir's weir's weir's weir's weir's weir's weir's slope is strengthened by laminating a different kind of membrane material on the same kind of membrane material as that of the weir's cylindrical body. Flexible membrane undulating weir. (4) Request for registration of a utility model in which the strength of the weir's weir's weir's weir's weir's weir's weir's weir's weir's weir's base is strengthened by making the weir's base using a high-strength membrane material different from that of the weir's cylindrical body's membrane material and joining it with the weir's cylindrical weir's cylindrical body. An undulating weir made of a flexible membrane according to item (1). (5) The undulating weir made of a flexible membrane according to claim (1) of the utility model registration claim, in which the strength of the membrane material of the weir is strengthened by reinforcing the strength only in the direction perpendicular to the flow using blind fabric or the like. (6) In the developed view of the weir at collapse shown in Figure 7, the upstream membrane is shown in the shaded area shown in Figure a, and the downstream membrane is shown in Figure b.
Flexibility as described in paragraph (1), (2), (3), (4), or (5) of the utility model registration claim, in which strength is reinforced in the shaded portion shown in Membrane undulating weir.
