Abstract
The invention relates to a pile construction comprising a number of steel tube sections (1) that are joined together. Each tube section (1) is formed with joining portions (2, 4) in its respective ends. One joining portion is constituted by a male end (2) having a conical envelope surface (3) and the other portion by a socket end (4), the interior surface (5) of which is conical in correspondence to the conicity of the male end (2). When the tube sections (1) are joined the male end (2) of one section interacts with the socket end (4) of the next section, so that a stiff joint is obtained.
