HORIZONTAL DISPLACEMENT METER OF UNDERGROUND STRUCTURE

摘要

The present invention relates to a displacement meter of an underground structure, and comprises: a vertical extension unit perpendicularly installed on a position spaced apart from a wall of an underground structure; a horizontal extension unit which is in contact with the wall; a displacement converting unit which converts the displacement of the horizontal extension unit in a horizontal direction to the displacement in a vertical direction and transmits the converted displacement to the vertical extension unit; and a displacement measuring unit measuring the vertical displacement of the vertical extension unit.
