2. Description of the Related Art Conventionally, a steel sheet pile wall in which steel sheet piles are continuously driven by engaging their claws with each other is used as a revetment for rivers, seas, etc., and corrosion prevention is provided on the upper portion of the steel sheet pile wall. ,
Alternatively, shade concrete is provided for beautifying the structure. This shade concrete was arranged by arranging a reinforcing bar on the upper part of the steel sheet pile wall, mounting a mold on the outer periphery of the wall, then placing concrete in the mold and removing the mold after hardening. .

However, the above-mentioned shade concrete has a long construction period because it is necessary to assemble the reinforcing bars or the formwork, and to place the concrete on site, and as a support material for the formwork, a temporary bracket is installed on the river side. There is a problem in that it is necessary to provide a staircase and a scaffolding as a workbench on the river side is required, so that temporary construction costs and time are required. Furthermore, when the water level of a river rises, on-site construction becomes impossible, and in winter construction, workability is poor, and there are problems in concrete quality and curing.

In order to solve the problem when using such a mold, Japanese Patent Laid-Open No. 1-262656 discloses
