Zusammenfassung:PROBLEM TO BE SOLVED: To provide a structural member and a construction method for a built-up passage for an observer, which can shorten a construction period and cut back on a construction cost, by solving the problem that the construction period cannot be reduced because the construction of the in-tunnel passage for the observer requires many processes and other works cannot be started until the completion of curing of concrete. SOLUTION: A steel guard fence (guard rail) for use in current road construction is effectively utilized, and the in-tunnel passage for the observer is constructed as a built-up type, so that the construction period of in-tunnel construction work can be shortened.
