TEST METHOD OF SOIL FOUNDATION WITH PILE WITH GRILL Russian patent published in 2015 - IPC E02D33/00 

FIELD: construction.

SUBSTANCE: test method of a soil foundation with a pile with a grill involves application of a vertical force to a pile with a grill in the form of a square plate in a plan view, measurement of the applied force and settlement of the pile and calculation of soil resistance. A grill plate is horizontal and symmetrical relative to the pile and it has dimensions of sides, which are by 6 times larger than diameter of the pile, with thickness that is by 40 times less than the dimension of plate sides and from material with elasticity modulus of less than 210000 MPa, brought to the surface of the soil foundation till complete contact and rigidly fixed on the pile head, with that, at the same time, vertical movements of four angular points of the grill plate are measured and resistance of the soil foundation to the grill and the pile is calculated as per the specified relationships.

EFFECT: identity of tests of a soil foundation; improvement of reliable results at one test; simplification and cheapening of a test technology of the soil foundation with a pile with a grill.
