AUTOMATIC SEGMENT ASSEMBLY ROBOT FOR SHIELD TUNNELING MACHINE

Tunnels are formed with the aid of precast reinforced-concrete segments. Erecting and positioning such segments using conventional erectors is tough and hazardous work. Labor-saving automation has long been awaited. The author's development of an automatic segment assembly robot that manipulates approximately 5-ton weight segments to form a 9.5-m-diameter ring should help the situation. The robot has already found use in a 600-m-long tunnel construction site in Tokyo. High-precision assembly is achieved thanks to a light-section method that applies laser-slit lighting and to digital servo technology. The benefit of automation tied in with a manual-remote hybrid control system reduces assembly time.
