According to the method for constructing a retaining wall of the present invention, concrete is poured into a concrete placing formwork in which an embedded weir plate and a decorative weir plate are connected by connecting metal fittings, and only the concrete is cured. Since the retaining wall is completed in, the construction period required for constructing the retaining wall can be shortened and labor can be saved, and the retaining wall formwork can be constructed without requiring skill in assembling. The embedding weir plate and the makeup weir plate are strong weir plates because PC embedding panels and decorative panels that are continuously arranged vertically and horizontally are connected by reinforcing bars arranged in a grid pattern. It becomes stronger than the conventional retaining wall because it becomes a structural body of the retaining wall integrated with the concrete placed in between, and the work process is reduced because it is not necessary to dismantle the formwork after hardening the concrete. In addition, since it does not use wooden formwork, it is useful for protecting natural resources, and because the formwork is not disassembled and the waste material accompanying it does not appear,
There is no cost for waste treatment, and it also helps reduce waste.

When the PC-embedded panel is made of one selected from concrete, resin concrete, FRP and GRC, it is possible to obtain a strong embedding dam plate and select a panel suitable for the construction site. be able to. The decorative panel constituting the decorative barrier plate is a panel formed by one layer selected from concrete, resin concrete, FRP, GRC, or a multilayer panel formed by using two or more of the above materials. Since the panel can be used, it is possible to select a panel suitable for various construction sites, and it is possible to improve the strength and aesthetics of the retaining wall surface. Further, the connecting metal fittings for connecting the decorative dam plate and the embedded dam plate are provided with elongated holes at positions symmetrical to the bending line of the thin steel plate elastically deformed into a substantially V-shaped cross section, and the outer end of the decorative dam plate is formed. The elastic force of the thin steel plate is obtained by inserting the inner end sides of the two connecting rods having the locking portions for locking the reinforcing bar and the reinforcing bar of the embedded dam plate into the two long holes of the thin steel plate bent in a substantially V-shaped cross section. Thus, when the two connecting rods are crimped together, the decorative barrier plate and the embedded barrier plate can be easily connected, and the time required to construct the form of the retaining wall can be shortened.
