To provide a centrifugal force molding method for a segment for a shield construction method which not only facilitates the manufacture but also has a good quality such as the manufacturing precision or strength, and in addition, which can reduce the manufacturing cost.
The segment for the shield construction method is centrifugal force-molded by using a centrifugal mold 110 for centrifugal force-molding a buried pipe for the propelling method. On the internal side of the centrifugal mold 110, a plurality of inter-ring partitioning members 120 are arranged in the rotating axis direction, and at the same time, a plurality of inter-segment partitioning members are arranged in the circumferential direction. By laying concrete while rotating the centrifugal molding frame 110, the segments of a plurality of rings are centrifugal force-molded.
