Abstract
A method for forming a drilled pile wall in ground using a drilling device having a reamer and flushing with a medium to remove drilling waste during drilling, and non-rotating pipe piles equipped with interlocks. A vertical 1 hole is drilled while simultaneously placing a pipe pile in the drill hole. At least one subsequent vertical hole is drilled hole in the ground side by side with the drill hole while simultaneously placing a subsequent pipe pile in the subsequent drill hole while the interlocks of the subsequent pipe pile interlock with interlocks of the pipe pile to guide the subsequent pipe pile into the drill hole. Reinforcements are installed in the drill holes, concrete is cast into each pipe pile to form a concrete pile, and at least some of the pipe piles are lifted at least partly out of the drill hole after the concrete has been cast, but before the concrete has bonded rigid to form a unified watertight pile wall. The invention also relates to a pile wall.
