Segment joint structure, segment assembly method and its disassembly method, segment assembly equipment and segment disassembly equipment

摘要

PROBLEM TO BE SOLVED: To reduce a stroke required for assembling a segment and to easily disassemble the segment from the inside of a tunnel, a joint structure of the segment, a method of assembling the segment and a method of disassembling the segment, a segment assembling device and a segment disassembling. Provide the device. A joint structure connects a plurality of segments 1B and 1K to each other in the tunnel circumferential direction. The guide unit guides the segment 1K to be assembled in order to insert the segment 1K to be assembled next to the assembled segment 1B from the diagonal direction D2 with respect to the tunnel axial direction. The guide portion slidably guides the slide portion of the segment 1K to be assembled in the diagonal direction D2. The guide portion rotatably guides the segment 1K to be assembled so that the direction of the segment 1K to be assembled is from the oblique direction D2 to the tunnel axial direction.
