Water expansion ruber ribon installing between objects for preventing water from invading water inside space formed by the objects

摘要

The subject innovation relates to a construction and Public Works water swellable material index (止水 材) as used, more specifically, the number of suppressing the expansion of the water to be contacted in the longitudinal direction when expanded to absorb (吸水) the inflatable rubber It relates to jisupan.; It came to invent the jisupan which can suppress the conventional wave phenomena.; The subject innovation for the purpose of the wave is suppressed in the base has a H-shaped cross-section having a groove in a longitudinal direction on upper and lower portions; and; It characterized in that the coupling to be a swelling index of rubber material is interposed in the attachment groove of the base.
