Title:
LIGHT-WEIGHT GROUND INVESTIGATION MACHINE AND GROUND INVESTIGATION METHOD USING THE SAME
Document Type and Number:
Japanese Patent JP2017122375
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a light-weight ground investigation machine that is light-weighted to weight enabling carriage to a mountain district or the like, and a ground investigation method capable of more accurately determining ground properties by using the machine.SOLUTION: In a penetrometer 10, a pulley 26 to which dead weight of a hammer part 20 is applied is supported by a hanger 70 disposed on the upper side of a support part 24 and the lower parts of legs 64, 66, 68 constituting the support part 24 are supported on a ground 62 to be investigated directly or via a pedestal part 56. When the hammer part 20 is being lifted, the dead weight of the hammer part 20 applied to the pulley 26 acts upon a drive force generation part 22 through a reaction force transmission part 72 constituting the support part 24. Thereby, when the hammer part 20 is being lifted, the reaction force of force lifting the hammer part 20 is cancelled by the dead weight of the hammer part 20.SELECTED DRAWING: Figure 1
