PROBLEM TO BE SOLVED: To provide a boring machine which carries out drilling according to a central interpolation method with arrangement of a standard hole on the order of 10 m for consolidation grouting, without providing scaffolding. SOLUTION: The boring machine is comprised of a bucket bracket 10, a body 15, a shaft 16, a guide mounting 17, and a cylinder 18. The bucket bracket 10 is pivoted at the tip of an arm 9 for a hydraulic shovel-type mobile truck 1, by means of two pins 11, 13. The body 15 has its base portion mounted on a front surface of a base 14 which is detachably attached to a front surface of the bracket, and its distal end protrudes from an upper edge of the base at right angles. The shaft 16 is mounted on a side portion of a distal end of the body 15 so as to be located on a lateral side of the arm in parallel with the body. The guide mounting 17 is rotatably mounted on the shaft at right angles, for bearing a guide cell 20 of a rock drill 22. The cylinder 18 is rotatable about the shaft between a position that is in parallel with the front surface of the base and a position that is perpendicular to the front surface.
