摘要： A method and apparatus for increasing the load bearing capacity of tubular piles by freezing an area of soil surrounding the piles. A refrigeration unit is located on the surface of an offshore structure and circulates cold brine to an isolated section of the pile. The brine freezes the soil surrounding the pile. Freezing the soil increases the surface friction beween the pile and the soil, providing increased load bearing capacity.

摘要： The invention relates to a method and apparatus for increasing the capacity of a tubular driven pile. A refrigeration unit is lowered into the pile and grouted in place above a cement plug. The area between the refrigeration unit and the plug is filled with a secondary refrigerant. Seawater fills the pile above the refrigeration unit and is used for refrigeration unit cooling. The refrigeration unit cools the brine until the soil surrounding the pile is frozen. The adfreeze strength of the frozen soil and the pile increase the pull-out resistance of the pile. Further, the end-bearing capacity of the pile is increased as a result of the large frozen mass surrounding the pile.
