A surface connection type precast reinforced roadbed rigid wall structure and a method for constructing the same are provided to induce the integration of a reinforced roadbed rigid wall and an embankment and to form a load transmission structure by connecting precast concrete panels (PC panels) and backfilling material by a surface connection method and by injecting filling material between the reinforced roadbed rigid wall and the embankment, and are also provided to easily stack the precast concrete panels into the reinforced roadbed rigid wall with flexural rigidity by continuously arranging the reinforcing bars of the reinforced roadbed rigid wall using the flat ducts formed inside the precast concrete panels. The surface connection type precast reinforced roadbed rigid wall structure comprises: the embankment; a foundation part buried in the ground and having a foundation part protruding reinforcing bars vertically formed in the same; a reference frame having a reference connecting plate, used as a welded metal mesh installed when the embankment is formed, preventing verticality and soil leakage on a slope having a severe gradient, and installed to secure the stability of the embankment under and after construction; the precast concrete panels having the flat ducts and embedded plates, assembled to be stacked each other, and forming the reinforced roadbed rigid wall; and the filling material injected between the reinforced roadbed rigid wall and the embankment, wherein the precast concrete panels are connected to the reference frame by the surface connection method. |
