Abstract:
To provide a soil measuring method which enables soil properties to be accurately measured at each depth while preventing a rod from being affected by earth pressure.
In measurement in which a Swedish sounding tester 1 penetrates into the ground, a pipe 7 making a rod 3 freely rotatable and movable in an axial direction is externally fitted to the outside of the rod 3; separation is achieved so that sediment in the ground cannot be brought into contact with the rod 3; and soil properties in the ground are measured by preventing the rod 3 from being affected by earth pressure.
