Title:
APPARATUS FOR MEASURING GROUND DISPLACEMENT
Document Type and Number:
WIPO Patent Application WO/2010/050714
Kind Code:
A2
Abstract:
The present invention relates to an apparatus for measuring ground displacement, and specifically to an apparatus for measuring ground displacement that is inserted into an inclined tube that is drilled perpendicularly into the ground to enable movement along the length direction thereof and sensing by contact of the displacement inside the inclined tube, comprising: a sensing means that measures 3-dimensional coordinate displacement at each measurement timing when moving lengthwise in the inclined tube; a timing setup means that sets up said measurement timing; and a displacement calculation means that calculates the ground displacement from the 3-dimensional coordinate displacement data measured at said sensing means; because the moving part measures the displacement in a 3-dimensional (or 3-axial) direction on a real time basis according to the measurement timing while the moving part is moving within the inclined tube, the measurement process takes place without the need to take into account the minimum measurement interval, reference point, etc., thus, the problems of the prior art regarding measurement error due to inconsistency of the reference point, perpendicularity of punching, twist of the inclined tube, etc., are resolved.
