タの数が多くなって、コストアップにつながる。[0004] By the way, it is almost unavoidable in Japan that if heavy traffic such as dump trucks and backhoes are arranged in tandem in a place where traffic is frequent compared to the road width, the work range will be widened and traffic obstacles and safety will be increased. Sex problems arise. If the excavated soil is to be used as backfill soil as it is, the excavated soil must be transported by a dump truck. Another characteristic of the open shield method is that a series of heavy machinery works in unison, so the heavy machinery used, the operating equipment, and the operating
The number of data increases, leading to an increase in cost.
