Summary:The utility model discloses a turnplate for model selection of duct pieces of a shield tunneling machine. The turnplate for the model selection of the duct pieces of the shield tunneling machine comprises a stator and a rotor, the stator and the rotor are both of a disc shape, the stator is connected with the center of the rotor through a rotating shaft arranged in the center of the stator, the rotor can rotate in 360 degrees relative to the stator with the rotating shaft as a center, twelve locating points are evenly distributed on the upper surface of the stator in the peripheral direction, a circular ring with the center of the rotor as a circle center is arranged on the upper surface of the rotor, the circular ring is formed by six regions in a connection mode, the connecting sequence of the six regions is identical with the assembling sequence of each circle of duct pieces on the shield tunneling machine, and a T-shaped pointer is further arranged on the upper surface of the rotor. According to the turnp
