PURPOSE: A tunneling machine equipped with a laser nozzle is provided to minimize damage of a cutter head caused face to face with piles, reinforcing bars and bed rocks by a camera recognizing the exact location of obstacles and a breaker wrecking or cutting them, therefore to extend lifetime against a long-distance running, moreover to promote safe working conditions. CONSTITUTION: The tunneling machine equipped with a laser nozzle contains; a cutter head(300) provided with openings(320) and numbers of bits(310); a manipulator(420) provided with an arm(440) allowable to revolve and move by an arm motor, also helping a first hydraulic cylinder(430) horizontally move along a guide rail(410); a second hydraulic cylinder adjusting slight movement of the arm; a third hydraulic cylinder opening a door; a front body(100) provided with a camera(450), a laser nozzle breaking or cutting obstacles, an air pump drying and removing all the pollutants sticking on obstacles by high air pressure; a refrigerant nozzle spraying liquid refrigerant for the complete break of obstacles sufficiently heated by laser beam; a couple of steering jacks; a tail body(200) comprising a motor(210) and a reduction gear box(220) necessary to run the cutter head.
