PURPOSE:To enable the easy assembly of a reinforcement member at the predetermined position by assembling the member with the shield propulsion jack forward part inserted into the steel pipe of a reinforcement for concrete. CONSTITUTION:A reinforcement member 1 to be assembled in a shielding machine is constituted with a steel pipe 2 and a reinforcement 3, and divided into a plural number in a circumferential direction. The forward part of a propulsion jack is inserted in the steel pipe 2 of the reinforcement 1 and the reinforcement member 1 is assembled in turn in a circumferential direction. Then, an inner mold frame 4 is assembled on the internal surface of the reinforcement member 1 and a tail frame 6 is used to close a gap at the side of the shielding machine between the drum plate of thereof and the inner mold frame 4. In addition, concrete is filled into the aforesaid gap. Thereafter, quick- curing mortar filled in the steel pipe 2 of the reinforcement member 1 is pressed with the propulsion jack, thereby enabling a shielded drilling and advancing process. Furthermore, after the completion of drilling, the forward part of the propulsion jack is drawn in turn from the inside of the steel pipe 2 and quick- curing mortar is instead filled into the steel pipe 2 in order.
