装置。A shield construction segment formed in an annular structure, comprising a hydraulic cylinder, a piston rod inserted into the cylinder and moved back and forth within the cylinder by hydraulic operation, and an operating piece attached to the tip of the piston rod. In a jacking device that propels the segment by bringing an action piece into contact with the ring rib surface, the pressure-receiving surface of the piston rod is formed into an arc shape curved in approximately the same direction as the annular shape of the segment. A segment propulsion jacking device that is characterized by a short distance between the two segments.
