10. The muck transfer system of shield tunnel according to claim 9, characterized in that in step S34, if the number of trackless automatic transport vehicles needs to be increased more than the available number of trackless automatic
; LL LU506668 transport vehicles, the control module sends a warning signal to the warning module to inform the staff.
