PROBLEM TO BE SOLVED: To provide a work scaffold which can be easily and safely constructed in the inside of a giant tank such as an agitation tank of water-granulated slag, and a construction method and a method of application of the work scaffold.SOLUTION: Polyhedron block-shaped styrene foams are stacked on a tank bottom and furthermore plates are spread thereon to form a foundation part, and thereafter polyhedron block-shaped styrene foams each having at least a pair of parallel faces are stacked one or more steps on the foundation part such that the parallel faces are horizontal. Then, plates are spread thereon to form a work floor part, thereby constructing a work scaffold. When the work floor part consists of a plurality of stages of styrene foam layers, work inside the tank is proceeded from a high place to a low place while sequentially decreasing the number of stages of the work floor part. |
