PLANT FOR SOUND PROCEDURE Russian patent published in 2015 - IPC E02D1/02 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction and is intended for use in engineering and geological survey in order to partition soil thickness in process of rotary drilling and determination of mechanical properties of soils in field conditions. A sound procedure plant, comprising a vehicle, on the platform of which there is a mast with a spinner, a hydraulic system providing for operation of crane drilling equipment, differing by the fact that with the purpose to expand functional capabilities and to increase accuracy of measurements, the plant is equipped with a measurement device, a device of axial loading and a laser range finder, a measurement device, one end of which is connected to the spinner shaft, the other one via a device of axial loading with a tail of a drilling string, comprises two force sensors, measurement of vertical movement of a drilling tool is carried out using a wireless laser range finder and a reflector fixed on the mast, measurement of drilling string and soil weight on its side surface is carried out using a force sensor, speed of rotation of a drilling tool is determined by means of analysis of radio signals recorded during rotation of the measurement device.

EFFECT: expansion of functional capabilities, increased accuracy of measurements.
