TECHNIQUE FOR CONTROLLING TUNNELING PARAMETERS OF SHIELDED TUNNELING MACHINE FOR ROCKY REGION AT SHIELDED TUNNELING LAUNCH POINT

摘要

A technique for controlling the tunneling parameters of a shielded tunneling machine for a rocky region at a shielded tunneling launch point, said technique being aimed at situations in which rock is present during tunneling. By means of building pressure with a mud tank, controlling shielded tunneling speed, controlling the amount of muck excavated, and controlling synchronous grouting and secondary grouting, the influence of the presence of rock on shielded construction is fundamentally eliminated, thus realizing the safe and smooth execution of shielded construction.
