FIELD: construction. ^ SUBSTANCE: invention relates to construction and may be used to make foundations of buildings, houses and other engineering structures for tunnelling of pilot holes under complicated soil conditions with driving of reinforced concrete piles in it, metal pipe and other piling elements, and also to manufacture driving concrete piles in soil. Device comprises motor, reducer, auger with starter, carriage with block for suspension to mast of piling plant. Reducer is arranged in the form of planetary component part and double-stage cylindrical gear, which connects mutually aligned shafts with rolling bearing, for instance, conical one - shaft of motor and inlet shaft of planetary component of reducer, satellites of which are arranged as double-staged, the first stage is engaged with solar wheel, and the second stage is engaged with support wheel. ^ EFFECT: increased efficiency in drilling of wells under complicated soil conditions. ^ 2 cl, 3 dwg |
