GROUND DISPLACEMENT CONFIRMATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a ground displacement confirmation device for confirming at least displacement in an approaching direction or/and an alienating direction among displacement generated between two spots of a ground.

SOLUTION: A ground displacement confirmation device 10 for detecting the displacement of a ground comprises: a first display member 12 partially fixed to a specific site G1 of a ground G, and including a first display area; and a second display member 22 partially fixed to the other specific site G2 of the ground G, and including a second display area 24 covering the first display area. It is configured such that when at least ground displacement to an approaching direction or/and an alienating direction is generated between the specific site of the ground and the other specific site of the ground, a visible deviation is generated in the positional relation of the first display area with respect to the second display area.
