Abstract

PURPOSE: To accurately cut off water between a wave-making plate and the wall surface of waterway by inserting a strip-like water cut-off member in a guide groove formed along the periphery of the wave-making plate within the waterway, mounting a backup tube in the groove, and injecting a fluid into the tube.
CONSTITUTION: The wave-making procedure is carried out by operating periodically a servocylinder and reciprocally moving a wave-making plate 2 within the waterway 1. Into a backup tube 8 provided within a guide groove 6 at the peripheral side of the wave-making plate 2, there is injected a fluid such as air or the like via a fluid injecting hole 15 thereby to generate a slight pressure in addition to the water pressure. By this procedure, a strip-like water cut-off member 7 slides in the guide groove 6 by the back pressure due to the expansion of the tube 8, and a surface contacting member 72 comes into contact with a side wall surface 13 and a bottom wall surface 12, and the back surface of the surface contacting member 72 is backed with a flexible backing member 71. For this reason, the wave-making plate 2 and wall surface 13 are completely sealed together. Accordingly, the wave-making action can be carried out in a state where no water enters the back side of the wave- making plate 2.
