DEVICE FOR DRILLING WELLS AND DETERMINING DENSITY OF SOIL IN FIELD CONDITIONS

摘要

The proposed device for drilling wells and determining density of soil in field conditions contains a core drill with a bar end and additionally, for the purpose to simplify the design and extend the utility range of the device, a mechanical eliminator. The eliminator contains a piston and a ring, which is coupled with the piston by rods. The piston is installed in the casing of the core drill with a possibility to be displaced. The ring of the eliminator is arranged at the bar end of the drill.
