置計測装置。 A small-diameter measurement tube is installed inside the tunnel or in the pipeline in parallel with the tunnel or pipeline, and inside this measurement tube, a gyro probe with a built-in gyro, an accelerometer, and an inclinometer is inserted along the axial direction of the tube. The gyro probe is moved at a certain speed or higher, and the azimuth, inclination angle, and speed are continuously detected using the gyro, accelerometer, and inclinometer, as well as the distance traveled by a separate distance meter that measures the distance traveled by the gyro probe. In this method, the movement trajectory of the gyroscope is determined using a separate computing unit from these detection data, and the position of the tunnel or pipeline is measured from this movement trajectory. A winch characterized in that it is equipped with wheels, a wire is connected to one end of the probe, a wire that also serves as a signal line is connected to the other end, and winches are provided at both ends of a tunnel or conduit to feed out or wind up these wires. A position measuring device for tunnel construction using a driven gyroscope method.
