Abstract (en)
[origin: EP1087062A2] The present invention relates to an extension arrangement for piles (1,2) which are to be driven into the ground, wherein the upper end (3) of a lower pile (1) and the lower end (13) of an upper pile (2) are interconnected by a separate interconnecting portion (6) arranged axially at the ends (3,13) of said piles (1,2). Said interconnecting portion (6) is dimensioned to have such a fit that the lateral surfaces thereof will drift apart, due to a change in temperature, radially from the lateral surfaces of a counter-portion (3,13) which is axially in an overlying position therewith and connects thereto, while said lateral surfaces in a normal temperature, correspondingly, will press against each other. The present invention further relates to a method for extending piles (1,2) wherein the extension comprises outer and inner interconnecting portions (6;3,13) which are pushed into an overlying disposition. By means of a temperature difference said outer interconnecting portion (6) is expanded to be larger than said inner interconnecting portion (3,13), after which said outer (6) and said inner (3,13) interconnecting portions ar brought to move into said overlying position while the fitting clearance so provided prevails and then to clamp together in normal temperature. <IMAGE>
