SHIELD MACHINE FOR INCLINED SHAFT AND METHOD OF CONSTRUCTING HORIZONTAL SHAFT CONTINUED TO INCLINED SHAFT

摘要

PROBLEM TO BE SOLVED: To improve safety of execution and execution property. ;SOLUTION: By use of a shield machine 10 in which a slave machine 30 is housed in a parent machine 20, the working face side and shaft mouth side end surfaces of the parent machine 20 are formed to be crossed with the axial line of the parent machine 20 at an angle other than 90°, and the rotating shaft 35 of excavating means is arranged toward the vertical direction, a segment having a ring-to-ring joint surface horizontally formed thereon is assembled while the shield machine 10 is advanced to construct a inclined shaft 40. The slave machine 30 is started from the parent machine 20 in the lower part of the inclined shaft 40 to construct a horizontal shaft.;COPYRIGHT: (C)1997,JPO
