FIELD: construction, particularly methods for building foundation protection against frost heave in seasonally freezing ground.
SUBSTANCE: method involves controlling natural seasonal freezing of ground surrounding building foundation by artificial retarding of natural seasonal ground freezing through depth equal to that of seasonally frozen ground sitting and width equal to foundation width. Artificial retarding of natural seasonal ground freezing is initiated when mean daily temperature of ambient air becomes equal to negative value. Said artificial retarding is carried out simultaneously from all foundation sides through total seasonally freezing ground layer with speed less than natural seasonal freezing speed and equal to 0.5-1 cm/day. Said freezing speed is kept up to natural freezing of ground through all sitting depth.
EFFECT: simplified technology of heaving protection, increased capacity, decreased labor inputs and costs, increased efficiency and reliability.
