Title:
GROUND RIGIDITY MEASURING DEVICE, COMPACTOR, AND GROUND RIGIDITY MEASURING METHOD
Document Type and Number:
Japanese Patent JP2015151826
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a ground rigidity measuring device capable of easily measuring the ground rigidity, a compactor accompanying the same, and a ground rigidity measuring method.SOLUTION: A ground rigidity measuring device 1 includes: a loading roll 2 that applies loads to the ground; a support frame 101 that rotatably supports a shaft part 103a; a first distance measuring part 4 that measures a separation distance Dwith respect to the support frame 101 at a first point Xin the traveling direction from a point Xdirectly underneath the rotational center line O in a ground under the support frame 101; and a rigidity measuring part 6a that calculates a difference value ΔS between a deflection amount S at the first point Xand a deflection amount Sat the point Xdirectly underneath the rotational axis on the basis of the difference value between the measurement result by the first separation distance measuring part 4 and a standard separation distance Dat the point Xdirectly underneath the rotational axis and measures the ground rigidity utilizing at least the difference value ΔS. A compactor 100 includes the ground rigidity measuring device 1. A ground rigidity measuring method measures the ground rigidity using the ground rigidity measuring device 1.
