The present invention relates to a tunnel support installing method capable of being applied regardless of lower ground conditions. The purpose of the present invention is to provide a structure and a method to manage the displacement of a composite bridge and install a reverse composite slope tunnel support so that a temporary slope tunnel support controls an abnormal displacement, when the abnormal displacement caused by a construction error including a connected shape is generated, by forming the slope tunnel support by utilizing the base part or wall part of an abutment and a pier as a support base. To achieve the purpose, the structure to manage the displacement of a composite bridge and install a reverse composite slope tunnel support according to the present invention is formed to bear a load by supporting a bridge girder by installing a slope tunnel support on the base part or wall part of an abutment and pier, installing the tunnel support at the pier in a left/right symmetrical direction, and installing the tunnel support to be inclined at the abutment in one direction. To achieve the purpose, the method to manage the displacement of a composite bridge and install a reverse composite slope tunnel support according to the present invention comprises the following steps of: assembling and installing a girder on an abutment and a pier in a grid form; installing a slope tunnel support of a basic material written in a claim 2 of the present invention between the upper side of the base part of the abutment and pier and the lower side of the girder; bringing a predetermined load (P1) in an inclined direction by driving a loading jack installed in the lower part of the slope tunnel support; constructing a slab by depositing and curing concrete on the girder; and dismantling the slope tunnel support after the construction of the slab. |
