SOIL TEST DEVICE Russian patent published in 2015 - IPC E02D1/00 G01N19/00 

FIELD: construction.

SUBSTANCE: device includes a loading die, a load application unit, a thrust system and a measurement system. The die is made in the form of a stiff structure of a square shape. Under the die there arranged is an elastic plate with dimensions of the die in a plan view, with thickness of 0.05-0.1 of the size of the die sides and elasticity modulus of 30-50 MPa. A rectangular coordinate grid is applied to lateral sides of the elastic plate. The measurement system includes a recorder of the applied load and a die settlement recorder. On the lateral sides of the die there rigidly fixed on its symmetry axes by means of brackets are video recorders of deformation of the elastic plate with a possibility of complete vision of lateral sides of the elastic plate.

EFFECT: simplifying and cheapening of determination of distribution of reactive voltage of a soil foundation at any arbitrary points along the die bottom and improving reliability of results at one test.
