FIELD: building, particularly to erect foundation bases in permafrost ground.
SUBSTANCE: method for tubular pile driving in permafrost ground involves drilling hole; installing pile in the hole and leaving it as it is inside the hole up to thermal permafrost ground regime recovery. To install pile in the ground inventive insert having diameter smaller than hole diameter in lowered in hole along central hole axis. Space between the insert and hole wall is filled with loose ground. Then the pile having inner diameter practically equal to outer diameter of the insert and opened lower end is driven in the loose ground. After that the insert is removed from hole. Other variants of pile driving are also disclosed.
EFFECT: increased building and assembly job efficiency due to decreased time of pile freezing in permafrost ground and improved load-bearing capacity of piles.
