Wherein the cutting tool 4 is located at the front side of the ripping tool 2 in the ripping direction, and the rotary drive means 3 is capable of driving the cutting tool 4 to rotate about the above-mentioned axis of rotation, and is rotatable outside the ripping tool 2 in the radial direction. Since the rotary drive 3 drives the cutter 4 to rotate about the axis of rotation and the cutter 4 is located on the front side of the ripping tool 2 in the ripping direction, it is possible to make the cutter 4 form an annular kerf on the front side of the ripping tool 2, and since the cutter 4 rotates radially outward of the ripping tool 2, the ripping tool 2 rippes in the annular kerf formed by the cutter 4 and preferably a plurality of ripping tools 2 are distributed in the annular kerf formed by the cutter 4. The tunneling tool 2 is a tool capable of tunneling underground, and the cutting tool 4 is a tool capable of cutting reinforced concrete.
