DEVICE FOR PERFORMANCE OF STATIC PROBING OF SOILS WITH VARIABLE DENSITY Russian patent published in 2010 - IPC E02D1/02 

FIELD: construction.

SUBSTANCE: device for performance of static probing of soils with variable solidity consists of hollow auger column and bale auger chisel, which comprises body with blades and pilot cutter. One of auger chisel blades is arranged of larger size compared to the other one, and is rigidly connected to body of auger chisel and flange, and blade of smaller size is hingedly joined to body of auger chisel, to provide for its inclination from axis, and is arranged as a whole with pilot cutter, upper end of which is a valve and enters internal cavity of auger chisel body, overlapping it. Upper end of larger blade rigidly fixed to body of auger chisel is installed higher than end of smaller blade end.

EFFECT: provision of possibility to perform research of soils with variable solidity by means of static probing without withdrawal of drilling assembly and rock-destroying tool from well with high efficiency of specified works, reduced material intensity and time required for research performance.
