Abstract
A multifunctional screw drill and reaming device, for the testing of the structure and composition of various soil types, as well as for sampling and boring, extracting and injecting of gases and various types of chemicals as well as liquids, slurry, granules and solids. Screws can be hydraulically, pneumatically, mechanically, electrically or manually driven. Dependent upon the operation, the secondary screws (2) can rotate and change position or rotational direction within the primary screw's bore (1), or both primary (1) and secondary screws (2) can be coupled and rotate as one unit.
