    • PROBLEM TO BE SOLVED: To accurately perform drilling along a schedule line shape without being controlled by a soil property.SOLUTION: A drilling device 1 includes: an outer piece 3 connected to a rod; an inner piece 5 extrudably housed inside the outer piece; and a position information transmitter 7 used for position detection by a sonde locator system. The position information transmitter is equipped with an attaching/detaching mechanism 9 which enables detachment and reattachment of the transmitter in the middle of drilling, and a sonde and an inclinometer are stored inside. When using percussion in the middle of drilling, a latch 93 of the attaching/detaching mechanism is released, and only the position information transmitter is tentatively recovered. Thus, in the state of being capable of surely protecting the position information transmitter from an impact, striking force is given to a distal end of the drilling device. When the percussion is ended, the position information transmitter is pushed back to an original position and reattached to the outer piece. Thus, accurate position detection by the sonde locator system can be restarted.

    • PROBLEM TO BE SOLVED: To provide a method of recording data which maximally utilizes the capacity of a storage memory and stores a maximum a mount of data every fixed time intervals.
      SOLUTION: For sampling waveform data at fixed time intervals, the data recording method changes the sampling time intervals to equal and unequal intervals according to the dynamic and static changes of the data e.g. as shown in Fig. 1. The data are sampled with equal sampling intervals in a greatly changing data range (dynamic changing portions) to obtain precise data and with unequal sampling intervals such as logarithmic or root intervals in a little changing range (static changing portions) to avoid taking in the data uselessly.
