トンネル掘削機

Japanese Patent JP7174379

B2

To provide a tunnel excavator that prevents damage to the machine due to overload and helps stable tunnel construction.SOLUTION: A skin plate 12 of a tunnel excavator 10 is equipped with a sensor 14 that directly detects the sliding resistance in the tunnel extension direction between the outer peripheral surface of the skin plate and the earth and sand. Further, the sensor 14 for detecting the sliding resistance in the circumferential direction between the outer peripheral surface of the skin plate and the earth and sand may be equipped. Further, the sensor 14 for detecting the soil water pressure acting on the outer peripheral surface of the skin plate from the outside in the radial direction may be equipped. Alternatively, the sensor 14 that simultaneously detects the sliding resistance in the tunnel extension direction and the circumferential direction may be provided. Further, the sensor 14 that simultaneously detects the sliding resistance in the tunnel extension direction and the circumferential direction and the soil water pressure acting from the outside in the radial direction may be provided.SELECTED DRAWING: Figure 1
