PROBLEM TO BE SOLVED: To provide a construction method for an underground tubular structure capable of being favorably used when a relatively short tubular structure in the length is constructed in a natural ground. SOLUTION: When a tubular structure 1 with a substantially equal section is constructed in a natural ground N, a plurality of wall members 11, 12(21-24) obtained by dividing the wall body of the tubular structure 1 into a plurality of pieces along the longitudinal direction are prepared. These wall members 11, 12 are inserted respectively into the corresponding positions in the wall body construction location of the tubular structure 1 in the natural ground G. These wall members 11, 12 inserted in the natural ground G are connected to each other. COPYRIGHT: (C)2004,JPO
