Method for manufacturing large flexible film undulation dam body

摘要

To provide a weir having a weir height of more than 1.5 m, which has stable strength after manufacture and has excellent durability and aesthetic appearance, without reducing the equipment cost and without increasing the installation area of the apparatus, Provided is a method for manufacturing a large flexible film undulation dam body. SOLUTION: An aggregate in which end edges in the longitudinal direction of laminated bodies 20 in an unvulcanized state adjacent to each other in the width direction are bonded to each other is vertically superimposed so that the longitudinal direction of the aggregate is In a direction perpendicular to the long side of the vulcanizing press region in the vulcanizing press device 12 from the direction perpendicularly intersecting the long side of the vulcanizing press region into the vulcanizing press region and subjected to press vulcanization The process of joining the edge portions in the longitudinal direction of adjacent flexible film sheet laminates and the edge portions on one side of the aggregate overlapping vertically and conveying them to the outside of the vulcanization press area Repeat until the length in the direction along the short side of the vulcanization press area in the sulfurized area reaches the predetermined length required for use as the flexible membrane relief dam main body.
