知装置。In a mechanical shield tunnel excavator, a dual ultrasonic or acoustic transmitting/receiving device with two or more frequencies is installed on the cutter disk or the part of the bulkhead that faces the cutter disk, and transmits acoustic waves or ultrasonic waves toward the face ground in front of the cutter disk. A face collapse detection device for seeded tunnel excavators that emits sound waves, detects the reflected waves, and uses the detected waves to determine the structure of the ground at the face.
