Position-fitting or positioning is made by position correcting action on X, Y and Z axes and attitude correcting action on X, Y and Z axes. At that time, in the case a segment is gripped, the position fitting of the segment to a grout hole 12d in which a grip mechanism 31 is carried is carried out. The gripped segment is fitted to the existing segment to carry out mechanically work to place at a built-up position. According to the constitution, an erector space L1 can be enlarged by distributing guide rails 35, linear bearings 36, slide jacks 22 and 24, etc., in X axis to arranged.
