Abstract:

For safe and efficient execution using the microtunneling method, it is necessary to understand both buried objects and ground information. The authors adopted an electromagnetic wave sensing system, devised an antenna that can be installed in a microtunneling driving machine with a diameter of approximately ø350 mm, and incorporated an original analysis algorithm to develop a frontward sensing system capable of automatically judging the locations of buried objects. This system made it possible to accurately detect both the presence and distance to buried objects to the front and sides of the driving machine, thus improving driving safety and efficiency.
