The present invention relates to a non-abutment rigid-frame bridge using a precast concrete wall and a pile, and a construction method for the same. The purpose of the non-abutment rigid-frame bridge is to: improve constructability as a structure except for a floor unit of an upper structure is constructed using precast concrete; stably induce a movement of a structure by a temperature change; and obtain ground stability of a backfill part. According to the present invention, the non-abutment rigid-frame bridge using the precast concrete wall and the pile includes: one or more piles (10) individually constructed on sides facing each other on both sides of a road or a river in order for a head unit to protrude from the ground whereas a lower part is embedded in the ground; a precast concrete wall (20) constructed in order for the head unit of the pile to penetrate the upper part of a pile insertion hole, wherein the precast concrete wall (20) comprises a hollow unit (21) and the one or more pile insertion holes (22) inside; a socket (50) which is a concrete body with a hole, wherein the socket is mounted on the hollow unit of the precast concrete wall to be able to move and is connected to the head unit of the pile through the hole; an upper structure (30) which is integrated with the pile and the socket through a girder (31) arranged to cross a river or a road, wherein both sides of the girder in the longitudinal direction are mounted on the precast concrete wall, and through a floor unit (32) constructed using concrete across the inside of the socket, a point unit in which the upper part of the socket of the girder are connected to each other, and the upper part of the girder; and a pavement layer constructed on the upper structure. While the precast concrete wall is not moved, the pile and the upper structure are moved in the precast concrete wall. |
