PILE ERECTED IN PERMAFROST SOIL Russian patent published in 2019 - IPC E02D5/36 E02D27/35 

FIELD: construction.

SUBSTANCE: invention relates to construction and can be used in construction of pile foundations on permafrost soils. Pile erected in permafrost soil comprises tubular pile shaft installed in well designed with diameter exceeding section of tubular pile shaft. At that, formed space between tubular pile shaft and well walls is filled with solution which is frozen after installation. Tubular pile shaft is made in the form of armored structure containing tubular reinforcement frame with coarse aggregate in the form of stone, which is formed by external and internal coaxially located cylindrical frames from reinforcement rods, which are combined in each frame by transverse rings and centralizers, connecting frames between each other. Outside and inside tubular reinforcement frame is covered with metal mesh attached to reinforcement rods of outer and inner frames and holding filler in tubular space between frames. Central cavity of tubular pile shaft, cavities between large aggregate of reinforced-stone structure and space between it and walls of well are filled with solution of clay with cement.

EFFECT: higher bearing capacity of the pile, higher resistance of the torque pile, as well as maintaining stability and sudden thawing.
