摘要： PROBLEM TO BE SOLVED: To provide a boring machine capable of drilling an underground hole having a rectangular section, and a boring device capable of minimizing bad effects on a tunnel shielding material with a relatively small required space within a tunnel. SOLUTION: The boring device 20 forms a circular underground beam 12 in a natural ground 11 by propelling a rectangular sectional circular short pipe including a thrust transmission pipe provided with the boring machine at the tip from a start mouth 94 opened in a wall surface 10 located near the bottom of a tunnel T. A start frame 30 disposed in a position facing the start mouth 94 within the tunnel T includes a base pushing jack 22 for propelling the thrust transmission pipe from the start mouth 94 toward the natural ground 11, a guide rail and a guide roller for propelling the thrust transmission pipe toward the natural ground 11 along a preset curvature radius, and a retaining means for retaining the circular short pipe in a fixed attitude relative to the thrust transmission pipe.
