Abstract
A shield tunneling machine in which a segment holding member is movable through a lifting beam in the radial direction of a shield frame so that the segment holding member holds a segment and sets it at a predetermined position in the circumferential direction of a tunnel within the shield frame; and an end balancer is pivotably connected to a base or root balancer which in turn is slidably mounted on the lifting beam so that the segment held by the segment holding member is correctly set at a predetermined position while the posture of the segment is suitably adjusted, whereby the erection and assembly of segments can be easily accomplished.
