Summary:The invention discloses a rotary disc for segment selection of a shield tunneling machine. The rotary disc comprises a stator and a rotor which are both disc-shaped, the stator is connected with the center of the rotor through a rotating shaft arranged at the center of the stator, the rotor can rotate by 360 degrees relative to the stator by centering on the rotating shaft, 12 positioning points are distributed on the upper surface of the stator uniformly along the circumferential direction, a circular ring taking the center of the rotor as the circle center is arranged on the upper surface of the rotor and composed of six areas which are connected, the connection sequence of the six areas is in accordance with the assembly sequence of segments in each circle, and a 'T'-shaped pointer is further arranged on the upper surface of the rotor. Only the rotor needs to be rotated to place a horizontal section of the 'T'-shaped pointer on the rotor at the minimum tail clearance position or maximum cylinder stroke pos
