Description of the Related Art In recent years, it has been practiced to apply a makeup that serves both protection and scenic views to a concrete wall surface of a retaining wall so as to have an appearance that is compatible with a natural environment. In such a scenic construction work, if natural stone is used as a cosmetic material and a skilled worker piles up or attaches the natural stone on the front of the retaining wall, the material cost and labor cost increase. For this reason, a method has been proposed in which a decorative veneer with a surface shape imitating natural stone is attached to the front of the retaining wall and the decorative veneer surface is colored and painted as necessary. Was still bulky.

Further, a support form such as a plywood is provided with stud bolts at a predetermined interval in front of the retaining wall, and a form form such as styrofoam is provided on the support form, and is poured between the retaining wall and the form form. After the concrete has hardened, a method of removing the supporting formwork and shape formwork has also been proposed, but since it is a complicated process, it is necessary to secure skilled field workers,
The labor cost increased, and it was necessary for workers to enter the narrow space between the supporting formwork and the retaining wall to perform pattern matching of the formwork, resulting in poor workability.

In the makeup system disclosed in Japanese Patent Application Laid-Open No. 4-118425, a concrete veneer is mounted with stud bolts at regular intervals in front of a retaining wall, and concrete is poured between the retaining walls. The veneer is bonded to the retaining wall by curing, and the veneer used as the formwork is used as it is as a member of the landscape,
Material costs and labor costs have been reduced, and workability has been improved.However, the nuts connecting the decorative panels to the stud bolts are exposed on the front of the decorative panels. As a result, the front of the veneer was stained, and the effect of the landscape of the veneer was reduced.
