Abstract: The present sampler is adapted to take soil samples from the ground surface, from a borehole sunk by other tools, as well as for drilling shallow boreholes. The sampler is provided with an air-operated percussion mechanism and a soil sample receiving sleeve arranged coaxially thereto. The side surface of the sleeve is provided with an annular ridge having a diameter somewhat larger than the diameter of the percussion mechanism housing. This feature enables a reduction of the forces applied to the sampler to sink it into or withdraw it from the soil.

Abstract: A device for taking soil samples from a hole drilled in the ground by another tool, and for drilling shallow holes. The device comprises a pneumatic impact mechanism rigidly connected with a soil sampling socket provided with an appliance for holding the soil sample in the socket when the latter is being extracted from the hole. This appliance is made in the form of an elastic inflatable element which, being inflated with compressed gas, covers completely the inner cross-sectional area of the socket, thus making it possible to take complete and high-quality samples irrespective of the type and condition of the soil.

Abstract: The device features its housing carrying the soil sampling ing socket and the striker arranged coaxially to said socket, and adapted to act thereupon and establish some chambers in said housing, which are alternatively communicated, through the inlet fitting and the piping connected thereto, with a source of compressed air for the striker to perform forward and return strokes. The piping portion immersed in water is essentially a rigid pipe joined with the inlet fitting by way of an axially spring-loaded sleeve whose one end is rigidly connected to said pipe. Arranged along said pipe is another pipe rigidly coupled thereto and serving for used-up gas to discharge from said chambers to the water surface.Such a device is applicable for soil sampling at depths amounting to several scores of meters.
