Title:
CONNECTING SECTION OF SEGMENT FOR TUNNEL
Document Type and Number:
Japanese Patent JP3933296
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide the connecting section of a segment for a tunnel, in which the machining of the connecting section and the connecting works of a segment body are facilitated and specified clamping force can be generated.
SOLUTION: The second connecting section R2 of a second segment body S2 is pushed into the first connecting section R1 of a first segment body S1 from the front side to the interior side in the tunnel longitudinal direction Y for coupling the second segment body S2 with the existing first segment body S1 in the tunnel peripheral direction X and pulled and joined mutually in the connecting section of the segment for the tunnel. An engaging section 5 and a surface to be engaged 2 inclined in the tunnel peripheral direction X to the pushing-in direction Y of the second segment body S2 and mutually engaged freely are both distributed and formed to the second connecting section R2 and the first connecting section R1, and a place adjusting means A capable of adjusting the place of at least one of the engaging surface 5 and the surface to be engaged 2 in the tunnel peripheral direction X before the second segment body S2 is pushed in is mounted at that time.
