Moling apparatus and a ground sensing system therefor

(57) At the time of use, summary this 願発明 is 配設 (ed) by the discharge object driven in the foundation with the equipment which has a self-adapting function between the mode of vibration and oscillating collision mode according to the foundation resistance which encounters, A perception means (19) to perceive dynamic resistance of the foundation through which a discharge object passes, and a signal-processing means (106) to process the output of the above-mentioned perception means and to supply a dynamic resistance waveform, Since the foundation characteristic is specified, a foundation sensing system (10) equipped with a waveform recognition means (108) to make the above-mentioned dynamic resistance waveform correlate with the stored dynamic waveform is offered. The waveform recognition means may be equipped with the neural network work system.
