Abstract
An apparatus includes a head having an obverse side and a reverse side. The apparatus includes a vertical load cell detachably connected to the obverse side. The vertical load cell in operation measures a plurality of vertical loads at a respective plurality of ground depths. The apparatus includes a plurality of pins connected to the reverse side. Each pin of the plurality of pins includes a rod and a cone connected to the rod. The apparatus includes a torsional load cell detachably connected to the obverse side. The torsional load cell in operation measures a plurality of torques at a respective plurality of rotational angles.
Claims16
An apparatus comprising:
- a head comprising an obverse side and a reverse side;
- a vertical load cell detachably connected to said obverse side;
- a plurality of pins connected to said reverse side, each pin of said plurality of pins comprising a rod and a cone connected to said rod, said rod comprising a rod diameter, said cone comprising a cone diameter. said cone diameter being larger than said rod diameter, said plurality of pins in contact with soil and comprising a plurality of vertical loads at a respective plurality of ground depths, said vertical load cell in operation measuring the plurality of vertical loads at the respective plurality of ground depths;
- and
- a torsional load cell detachably connected to said obverse side, said plurality of pins in contact with soil and comprising a plurality of torques at a respective plurality of rotational angles, said torsional load cell in operation measuring a the plurality of torques at a the respective plurality of rotational angles.
An apparatus comprising:
- a head comprising an obverse side and a reverse side;
- a vertical load cell detachably connected to said obverse side;
- a plurality of pins connected to said reverse side, each pin of said plurality of pins comprising a rod and a cone connected to said rod, said plurality of pins in contact with soil comprising a plurality of vertical loads at a respective plurality of ground depths, said vertical load cell in operation measuring the plurality of vertical loads at the respective plurality of ground depths;
- a torsional load cell detachably connected to said obverse side, said plurality of pins in contact with soil comprising a plurality of torques at a respective plurality of rotational angles, said torsional load cell in operation measuring the plurality of torques at the respective plurality of rotational angles;
- and
- a processor communicating one of directly and indirectly with said vertical load cell and said torsional load cell, said processor converting the measured plurality of vertical loads into a plurality of vertical penetration shear strength values at the respective plurality of ground depths, said processor converting the measured plurality of torques into a plurality of rotational shear strength values at the respective plurality of rotational angles.
