| Abstract: | Since it is very difficult to repair or replace components of the main bearing inside the tunnel during the construction of TBM,a proposition of repairing or replacing the wear-resisting ring of the main bearing for the first time inside the tunnel is put forward in the paper,with its working procedures and methods for implementation,and points for attention introduced.Through the correct decision-making and the rational organization of construction,the scheduled duration is greatly shortened,the normal excavation soon restored,and very good effects achieved. |
