Claims (1)

[Scope of utility model registration request] A flexible membrane envelope that forms a weir body is attached to at least the floor of a river, etc. in a direction across the river, and fluid is sent inside the envelope to expand and raise it up, and the fluid is discharged from the interior of the envelope to cause it to contract and fall down. In a weir that is designed to protect the weir by providing a cushioning material at the sheathing attachment part on the floor of a river, etc., rubber-coated cloth or rubber is used as a cushioning material to protect the sheathing attachment part. One end of a flexible membrane material such as a sheet is fixed with a bolt planted in the concrete foundation upstream of the enveloping attachment part, and the other end is extended downstream beyond the enveloping attachment part. An undulating weir made of flexible membrane characterized by:
