FIELD: construction.
SUBSTANCE: invention relates to construction and may be used for building pile foundations mainly in subsiding ground conditions with I type, bulk, highly porous clay, sand and other weak soils with low bearing capacity in their natural or anthropogenic addition. Method of piling of drive device, according to which well is created, is filled with soil material without compaction and a piled. Well is made by punching with making a compacted zone of soil on both side surface and bottom of the well. After piercing the well one creates a widened base by filling it with hard ground material in its lower part to the height of not less than two diameters of the well with subsequent compaction of ground material and creation of a widened base. Then well is filled with soil material without compaction. Piling is done with deepening of pile in a widened base to form additional zone of compacted soil material around piles.
EFFECT: technical result is improvement of carrying capacity of pile in weak soils, reduce of labour intensity.
