THE MANHOLE REPAIRING METHOD USING A COLLAPSIBLE MANHOL HOUSING SUPPORTHING APPARATUS AND A CAST FOR THE REPAIR WORK OF A MANHOLE

摘要

The present invention relates to a manhole repair method using a collapsible manhole housing supporting apparatus and a manhole repair cast. More specifically, a first fixed body and a second fixed body are installed at leg members to be engaged to an internal surface and an external surface of a manhole housing in order for the manhole housing supporting apparatus to have improved structural stability, and the external side is made of a tube, thereby enabling quick installation and demolition work of the mold during a manhole repair work to enhance workability. For the manhole repair work, the optimized mold and manhole housing supporting apparatus is used, and the construction is simplified in comparison with a conventional manhole repair method, thereby shortening a construction period.
