<p>A pile joint comprising two pile tubes (1, 2) with end surfaces in mutual contact (at 8) and a jointing sleeve (7) arranged inside the joint, wherein the ends (3, 4) of the pile tubes (1, 2) are widened cylindrically and coaxially with the extension of the pile tube to an internal diameter corresponding to the internal diameter of the pile tube increased with 1/2 to 2 times the thickness of the material in the pile tube. The jointing sleeve (7) has an external diameter substantially corresponding to said widened internal diameter, and in the joint sleeve (7) has a length that is less than the total length of the diameter-widened parts of the two pile tube ends (3, 4), and a method of producing the pile joint.</p> |
