Abstract
Improvements in the tommonstras for geotechnical studies, characterized by comprising a cylinder composed of a shirt and a piston, short in relation to this, adjusted through joints to the aforementioned shirt and a concentric guide tube to it, appearing shirt and tube attached to a head located at one of the ends of both elements, this head having on its free end a central hole for receiving a connecting rod to a conventional drilling machine or the like, provided with means for driving a fluid under pressure for its transfer through a conduit made in the same head, from this hole for receiving the rod into the cylinder, and a conduit that communicates inside the guide tube with a hole also made in its head in which there is a valve, whose step drive is made from the guide tube to the hole communicated with the outside.
