Abstract
PURPOSE: To prevent an abnormal falling of a rubber weir from occurring due to the adhesion of the inside walls of a swelling portion when a rubber weir is leveled, by a method wherein a small-diametered hollow portion is provided in a swelling portion of a rubber weir used for checking sea water or the like, and a fluid material hardenable at normal temperature is filled in the hollow portion to project the latter.
CONSTITUTION: A rubber weir is leveled by opening a valve and forcibly discharging a fluid out of the rubber weir by a pump. A fluid material solidifiable at normal temperature is filled into a hollow portion 3 to cause the latter to project into a swelling portion 1a, thereby forming gas passages 8 within the rubber weir when the rubber weir falls. As a result, the inside walls of the swelling portion 1a will not adhere to each other even under water pressure. In addition, since the air passages 8 are stretching longitudinally to a point near a fluid injection port along the hollow portion 3 filled with the solidified fluid material 7, the fluid which would otherwise remain in the rubber weir main body is moved through the passages 8 toward the injection port and discharged.
