It is provided. This face exploration device 1 detects the condition of the ground 16 immediately in front of the cutter frame 5 by receiving ultrasonic or electromagnetic wave signals transmitted along the face plate 6 from the ultrasonic or electromagnetic wave transmitter 14 to the receiver 15. It is designed to be detected. Specifically, as shown in FIG. 2, the ultrasonic or electromagnetic wave transmitter 14 is connected to a generator 18, and the electric signal from the generator 18 is transmitted to the ultrasonic or electromagnetic wave transmitter 14.
is designed to convert into ultrasonic or electromagnetic wave signals and transmit them. Further, a receiver 15 provided opposite to the ultrasonic wave or electromagnetic wave transmitter 14 is connected to a discrimination circuit 19, and the ultrasonic wave or electromagnetic wave signal received by the receiver 15 is converted into an electric signal by the discrimination circuit 19.

レーム５直前の地山１６の状態を検知することに成る。Transmission of the ultrasonic wave or electromagnetic wave signal is accomplished by the foot sound wave or electromagnetic wave transmitter 14 converting the electric signal from the generator 18 into an ultrasonic wave or electromagnetic wave signal and transmitting it. Due to the nature of this ultrasonic or electromagnetic wave signal propagating in muddy water but not in earth and sand, the receiver 15
The presence or absence of HA sound waves or electromagnetic wave signals is confirmed by this. For example, when an ultrasonic wave or electromagnetic wave signal is received, it is converted into an electric signal by the discrimination circuit 19 and sent to the ultrasonic wave or electromagnetic wave transmitter 14 and the receiver 1.
It is detected that there is a muddy water state between 5 and 5. On the other hand, if no signal is received, it means that there is mud. Roughly speaking, lit waves have stronger penetrating power than ultrasonic waves, and it is possible to investigate the concentration of highly concentrated water distribution and sediment deposits that are attenuated by ultrasonic waves. Since this is done while rotating the cutter frame 5 during the shield method construction, the state of the ground 16 immediately in front of the cutter frame 5 is detected while rotating in the circumferential direction of the cutter frame 5.
