Method for lining tunnel wall formed by shield excavation

摘要

A method for lining a tunnel wall formed by a shield excavation includes filling a space between the tunnel wall surface and the outer peripheral surface of a lining form in two stages by dividing space into two, portions. One stage of the method is carried out with a ring-shaped rearward end frame ring secured to excavator propelling jacks and disposed to define a first space portion and a second stage of the method is carried out accompanying forward propulsion of the excavator.
