摘要
PROBLEM TO BE SOLVED: To perform propulsion construction work by making a leader longer (increasing propulsion capability) than conventional leaders, using the same in ensuring the propulsion construction work, and causing the leader to start from a smaller vertical shaft than conventional vertical shafts. ;SOLUTION: This construction method is a double-phase, combination construction method involving different propulsion methods for an auxiliary leader 1 and a leader 2. The auxiliary leader 1 is used to secure the space required to assemble and install the leader 2. The leader 2 is assembled and installed after the space required for assembly and installation has been secured by the auxiliary leader 1, and is propelled up to a goal shaft.;COPYRIGHT: (C)1998,JPO
