HEATED PILE Russian patent published in 2005 - IPC

FIELD: heat engineering constructions.

SUBSTANCE: invention can be used as supports of different construction on permafrost. Proposed heated pile has reinforced concrete or metal shaft with inner or outer heated pipe in form of ribbed evaporator and condensers provided with metal strip ribbing arranged over ground surface with inclination to vertical part of shaft. Novelty is that heated pile is made T-shaped, and heated pipe in form of ribbed evaporator is made symmetrically double relative to axis of shaft with connection of some ends or its evaporators, other ends being connected with condensers. Evaporator ribbing is made in form of upward convex ring surfaces with central passes secured on inner surfaces of walls of heated pipe evaporators and uniformly distributed in height, and metal strip ribbing of condensers is element of horizontal part of T-shaped heated pile.

EFFECT: improved efficiency of heated pile, facilitated replacement of pile in case of failure.
