FLEXIBLE JOINT STRUCTURE FOR SHIELDED TUNNEL

摘要

PROBLEM TO BE SOLVED: To further simplify a flexible joint structure for a shielded tunnel while still making the most of an advantage of becoming easy in removing work from an interrupted part by forming a thrust receiving material in a wedge shape. SOLUTION: An inclined face is formed on opposed end surfaces 2a and 3a of themselves of a pair of front-rear tunnel end members 2 and 3 for forming an annular interrupted part G1. A wedge-shaped space is formed for inserting the wedge-shaped thrust receiving material 1. COPYRIGHT: (C)2005,JPO&NCIPI
