To provide a salt damage prevention-type wall surface structure which enables a wall surface structure in the case of the performance of the landscaping, restoration and new construction of an artificial rock, rich in surface undulations akin to those of a natural rock, to be shaped from concrete on a job site, and which hardly undergoes slat damage even on or near a coastline by sufficiently securing the thickness of cover concrete of a reinforcing bar.

A substitute for a form is constituted by attaching a net inside a lattice-shaped bar in which shaped reinforcing bars are lengthwise and crosswise connected together; concrete is infilled inside the net and cured; and subsequently, the lattice-shaped bar and the net are detached. Since the construction method is adopted, the objective rock wall-like undulations can be easily shaped from the lattice-shaped bar and the net; and the landscaping, restoration and new construction of the artificial rock, rich in the surface undulations akin to those of the natural rock, can be performed. The concrete is placed in a state in which a removal screw rod for mounting the lattice-shaped bar is inserted through a flexible hole. Thus, a cover concrete dimension is set sufficiently thick by infilling mortar into a trace hole from which the removal screw rod and the flexible hose are pulled out, so as to fill the trace hole. Consequently, this plain concrete wall structure can be achieved.
