FIELD: construction.
SUBSTANCE: invention relates to construction, in particular to methods of erection of pile bases and foundations, mainly in soft soils, and can be used in industrial and civil construction both in erection of new buildings and structures, and in reinforcement of foundations of old, damaged or requiring reconstruction at design pull-out loads, for example, when anchoring a slab from floating. Impression pile in the form of a pipe is equipped with a cap, a tip and a calibrator, the diameter of which exceeds the pipe diameter. Pile is equipped with additional calibrators; at that, each calibrator is made in the form of a truncated cone. At the level of each calibrator there are holes in the pipe with the possibility of supplying through them cement mortar with hardening retarder into the gap between the well wall and the pipe.
EFFECT: increasing bearing capacity of the pile on soil for pulling out.
