The excavating means is either a blade or a jet which formes at least one line segment connecting the the center (E) of gravity of the equilateral triangle with the vertex (M) thereof. The excavation is performed by revolving the excavating means in the orbit (C) with a prescribed angular speed and rotating the excavating means around the center of gravity with a prescribed angular speed. The ratio (η=L/r) of the radius (r) of the orbit (C) to a distance (L) between the center of gravity of the excavating means and the vertex thereof is selected, so that the cross-sectional shapes of the excavated holes (H1 and H2) adjacent to each other can mutually have complementarity and serve as continuous excavated cross sections.  <P>COPYRIGHT: (C)2004,JPO
