PROBLEM TO BE SOLVED: To provide an air bag fence usable for multiple purposes, effective in cleaning particularly inside a tunnel, usable as a large-sized air bag fence, a fence in need of cooling or a fence in need of thawing and self-standable also outdoors. SOLUTION: This air bag fence is constituted by connecting airtight front foundation cloth and rear foundation cloth by a large number of connecting threads of almost fixed length, applying airtight working to the peripheral edges, and providing a base part for self-standing. The air bag fence with the fixed thickness formed to self-stand is usable as a single body for the fence and usable for many purposes by forming cylindrical shape or polygonal shape by combination. The air bag fence is effective in cleaning particularly inside the tunnel by forming at least one face in an oblique shape or a circular arc shape, and usable as a large-sized air bag fence by providing a through part, as the fence in need of cooling or the fence in need of thawing by putting cold air, hot air or warm water. Further, the air bag fence with the fixed thickness is self-standable also outdoors by putting water. COPYRIGHT: (C)2004,JPO
