DEVICE FOR COMPLEX DETERMINATION OF PHYSICAL AND MECHANICAL PROPERTIES OF SOILS UNDER FIELD CONDITIONS Russian patent published in 2014 - IPC E02D1/08 

FIELD: construction.

SUBSTANCE: device for complex determination of physical and mechanical properties of soils under field conditions includes an anchor, a thrust beam, a load screw, a turning wheel, an impeller and a cutting ring. In order to enlarge functional capabilities and improve measurement accuracy, it is equipped with a servo drive with a screw, which is installed on the thrust beam, a torque sensor fixed on a tie rod with a circular die, a force sensor fixed in lower part of the servo drive, a vertical movement sensor installed at a reference point. The servo drive, the force sensor, the torque sensor, the vertical movement sensor are connected to the control unit and through an interface to a computer, thus forming a measurement system with direct and feedback communication between the sensors and the servo drive.

EFFECT: improving accuracy of loading and measurement by automatic control of performed tests.
