The radial faces configured to be moved towards respective radial faces of adjacent segments in order to form an annular tunnel portion, the circumferential faces configured to be moved towards respective circumferential faces of adjacent segments in order to form a linear extent of said tunnel along the longitudinal axis and an outer longitudinal face being at a greater distance than an inner longitudinal face from said longitudinal axis, is placed in contact with the ground, at least one investigation device is embedded in the arcuate structure to detect predetermined structural parameters. | 2020-04-16 |
