The plate comprises a shield tube (118) for protecting a portion of the tunnel boring machine (100), which is temporarily arranged between the borehole segments (112) for lining the borehole wall, and a sensor (116) arranged in the shield tube for detecting the distance between the shield tube and the borehole segments. The sensor is arranged away from the borehole wall in the inner surface of the shield tube. A supporting ring (122) and the lateral surface of shield tube are integrally formed from a single material. An independent claim is included for a tunnel boring machine. |
