Title:
METHOD AND SYSTEM FOR MEASURING DISPLACEMENT
Document Type and Number:
Japanese Patent JP2017040560
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To propose a method and a system for measuring displacement, which enable simple measurement of displacement of the foundation at a blind position.SOLUTION: The displacement measuring method for measuring a displacement amount of a measurement point 3 disposed on the ground surface, includes a relay point measuring work in which a displacement amount of a relay point 4 is measured from a reference point 5, which is a steady point, and a measurement point measuring work in which a laser beam LB is horizontally emitted from the relay point 4 toward a gauge rod 11 provided at the measurement point 3 and a numerical value of the gauge rod 11 irradiated with the laser beam LB is read.SELECTED DRAWING: Figure 1
