In a shield excavator that assembles segments by inserting a horizontally tapered key segment held by the grip of an erector device from the side between adjacent segments using a shield jack, during shield propulsion. When the shield jack stroke reaches the amount required for the above segment assembly, a mark that appears outside the end face of the existing segment,
A shield excavator characterized by having a tail plate provided on the inner periphery of the shield body. 2. A means for detecting a shield jack stroke in a shield excavator that assembles segments by laterally inserting a horizontally tapered key segment held by a grip of an erector device between adjacent segments by a shield jack; means for determining whether or not the shield jack stroke during shield propulsion has reached the amount required for segment assembly, based on the output of the detection means; and means for displaying the determination result on an operation panel. A shield excavator characterized by the following.
