重要な項目の１つとなっている。In recent years, this underground continuous wall construction method has been highly evaluated for its safety, workability, and rigidity. In particular, it has gained public attention as a construction method for effectively utilizing an underground space, and has been applied to a large depth in accordance with the expansion of its application. Shows the tendency of With the use of the underground continuous wall method and its deepening, construction management techniques for building high-quality walls are required, and in particular, excavation precision management for high-precision excavation is important. It has become one of.

問題となる。However, such management has the following problems, so that not only cannot the predetermined excavation accuracy be ensured, but also
There is a tendency to spend a great deal of time on correction excavation. In particular, such a tendency becomes more important as the depth increases.
【０００８】傾斜計（アナログ）は、その箇所におけ

後管理となることから、適切な掘削機の姿勢制御時期が
遅れがちとなるばかりでなく、修正掘削に多大な時間を
費やすことになる。[0009] Since the groove wall measurement is performed after excavation and is post-management, not only is the timing of appropriate attitude control of the excavator prone to be delayed, but also a large amount of time is spent for correction excavation.
