SEGMENT FOR TUNNEL LINING AND ITS ASSEMBLY METHOD |
摘要 |
PROBLEM TO BE SOLVED: To facilitate assembly of a segment for tunnel lining and simultaneously introduce prestress in the peripheral direction and in the tunnel axial direction of a tunnel lining body by using a short PC tension material. SOLUTION: The circumferential direction and the axial direction of a segment are connected to each other by alternately and sequentially introducing tensile force to a PC tension material for each of ring rows by alternately arranging segment rings made of segments for tunnel lining providing four pieces of PC tension material insertion ducts passing through to a side surface in the tunnel axial crossing direction from a side surface in the tunnel axial direction of the segment in a parallel crosses form in the tunnel axial direction.
