SHIELD LINING SEGMENT, SHIELD LINING STRUCTURE, AND METHOD OF CONSTRUCTING SHIELD LINING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a shield lining segment which exerts excellent rigidity to stress applied to a joint connecting the segments in a tunnel axial direction or concrete around the joint, and bending moment imposed by a shield jack during construction work, even if the width thereof in the tunnel axial direction is extended, and to provide a shield lining structure and a method of assembling the shield lining structure.;SOLUTION: The shield lining segment 1 is formed of: steel pipes 10 penetrating both edges of the segment 1 in the tunnel axial direction; and the joints 12 arranged at both edges of each steel pipe 10 for connecting the steel pipes 10 of the respective segments 1 adjacent to each other in the tunnel axial direction.;COPYRIGHT: (C)2007,JPO&INPIT
