PURPOSE: To automate drilling processes and achieve faster, reproducive and lower-cost drilling work by making measurements to select judgement that the drive of a buried pipe is started and finished and automatically controlling system management. ;CONSTITUTION: A drilling device 1 at the end contains an inclinometer 14, a soil pressure meter 15 and stroke length detecting meters 17, 18 as sensors, as well as an electromagnetic valve 19 to stroke-control a direction modifying part. Data from these are fed into a data processor 24 in a soil pit via multiple transfers 21, 25 and an I/O unit 23 to modify deviation from a target value in remote control. A target light receiver 22 is provided for monitoring in the drilling direction to receive radiated laser beams on the target plane and show the degree of the deviation. A primary pushing device 27 is provided in a vertical shaft to detect propulsion speed pressure for measuring the propulsion pressure and stroke of a propulsion jack. Then, the propulsion and retreat of the drilling device 1 is automatically judged, followed by automatic processing.;COPYRIGHT: (C)1995,JPO
