Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a segment for a shield tunneling method, which is equipped with stable cut-off properties and proper constructibility by surely filling a section between adjacently-arranged segments so as to ensure the smoothness of an inner surface. SOLUTION: A segment body 2 comprises a steel shell portion 21 which constitutes its curved outer surface and the inner-surface side of which is formed in an open shape, and a concrete structure portion 22 which is infilled into the steel shell portion 21. A caulking material 3 is provided at the edge of the segment body 2, and an anchor portion 31 is protrusively provided on the surface of adhesion to the concrete structure 22 in the caulking material 3. The anchor portion 31 is provided with a bent portion 311, and embedded in the concrete structure 22 so as to be integrated with the segment body 2. Additionally, a hollow portion 32 is formed inside the caulking material 3. COPYRIGHT: (C)2009,JPO&INPIT
