<P>PROBLEM TO BE SOLVED: To solve the problem that, when a water cut-off device is buried along inclination of a slope in the case of installing the water cut-off device in a building including a slope in the vicinity of a gateway, a clearance is formed between a water stop body and the building by the inclination angle of the slope when erecting the water stop body, thus causing infiltration of water into the building. <P>SOLUTION: A water cut-off device is structured in such a manner that infiltration of water into a building is prevented by erecting a water stop body even if a ground in which a water cut-off device is buried in the vicinity of a gateway is inclined due to a slope and that the water cut-off device does not impede comings and goings of people. <P>COPYRIGHT: (C)2013,JPO&INPIT |
