Zusammenfassung:PURPOSE:To carry out the positioning work for a segment safely and correctly by the less number of workers, by guiding a newly transported segment onto an already installed segment by a panel guide plate, etc. CONSTITUTION:A segment 3 to be installed newly is suspended, and transported over a segment setting device fixed on an already installed segment 2. The edge parts on the left and right sides and the lower edge part of the segment 3 are guide by the panel guide plates 72, 83, and 93, respectively. At the same time, the upper edge of the already installed segment 2 is automatically positioned at a prescribed position by lowering the segment 3 by its dead weight. At this time, the tilt of the segment 3 is finely adjusted by advancing and retreating the absorbing pads 71, 85, and 91 which are sucked on the segment 3 and support the segment 3.
