Zusammenfassung: | The present invention relates to an abutment structure using a PC block and an RC construction method which is constructed on a slope. To this end, the present invention comprises: a base unit composed of a plurality of first PC blocks combined at the upper portion of a discarded concrete layer; a sphere unit which is composed of a plurality of second PC blocks which are stacked and coupled in the height direction at the upper portion of the base unit; and an abutment coping unit which is stacked and coupled in the height direction at the upper portion of the sphere unit, and is composed of a plurality of third PC blocks which support a girder connected to a pier. Here, the abutment coping unit has a bridge seat support unit which is provided to support the girder by means of a PC wall body block which is stacked and coupled at the upper surface. The first PC blocks of the base unit, the second PC blocks of the sphere unit and the third PC blocks of the abutment coping unit have a reinforcing space unit which is located on the vertical line of the bridge seat support unit to be connected to each other. As for each reinforcing space unit, in a state in which a pillar reinforcing bar which is installed in parallel with a pile head exposed to the discarded concrete layer passes, an RC construction method is also performed to place a filled concrete on site such that the abutment support unit may be formed to support the load of the girder. Therefore, structural safety may be guaranteed.
