Then, the lining member is positioned at a predetermined long side position by a long side moving mechanism, a shift mechanism, and an axial center moving mechanism. In addition, the lining member on the short side is changed in posture using a bending rotation mechanism and an arm rotation mechanism provided on the holding frame, and the respective mechanisms are driven to be positioned at predetermined short side positions. Can be. Also, even if a support member (obstacle) such as an earth removal device is arranged near the short side position, the side member of the support member is held in a posture along the long side direction by holding the lining member on the short side portion. And by moving the lining member on the short side to a position along the short side by the refraction turning mechanism while moving to the short side position side, passing the side of the support member to the short side position. Can be easily positioned. Therefore, even in the rear space in the narrow shield machine, the long lining member can be smoothly supplied, the posture can be changed, and the lining member can be positioned at a predetermined position.

According to the second aspect of the present invention, even if the internal space of the existing lining body is narrow and the long lining member interferes with the reinforcing member when the long lining member is rotated, the shape is replaced with the reinforcing member. By disposing the holding device so that it does not interfere with the lining member, it is possible to reliably support the external force received by the lining when exposed from the rear end of the shield machine, and to reduce the internal space of the existing lining.
