The present invention relates to a non-abutment precast ramen bridge, which is rapidly constructed and structurally stable in the construction of a bridge, such as a bridge constructed along an embankment formed along a river, requiring excessive efforts and costs for constructing temporary facilities, and a construction method thereof. The non-abutment precast ramen bridge includes: a non-abutment lower structure on one side, including an RC girder continuously and longitudinally connecting upper ends of cast-in-place concrete piles constructed at intervals in a longitudinal direction; a non-abutment lower structure on the other side including a PC pillar separated from the non-abutment lower structure on one side in the transverse direction and a PC girder formed in the upper part of the PC pillar; a connection steel frame individually installed on the outer upper end of an inner deck constructed between the RC girder and the PC girder and on the inner upper end of an outer deck constructed on the outer side of the PC girder in a cantilever method; and a slab concrete integrally placed and cured such that the non-abutment lower structure on one side, and the upper part of the non-abutment lower structure on the other side, and the connection steel frame are embedded. |
