Weak soil anchor device to anchor one or several structures and method to arrange an anchor in weak soil

Abstract

Weak soil anchor device () for anchoring a number of structures, as well as method for arranging an anchoring in weak soils. Seen in a vertical operating position, the weak soil anchor device () comprises: an elongate inner continuous open box structure () with a triangular cross-section comprising a first wall surface (), second wall surface () and third wall surface (), an outer continuous open box structure () with a smaller vertical extent than the inner box structure () and having a triangular cross-section consisting of a first outer wall surface (), second outer wall surface () and third outer wall surface (), the vertical center area () of the first, second and third outer wall surfaces is connected to the inner elongate continuous open box structure () in a lower area of respectively an outer edge area between the first and second wall surface (), second and third wall surface () and the third and first wall surfaces (), and anchor brackets () are arranged in a lower outer area of the weak soil anchor device (), where the weak soil anchor device comprising the inner and outer box structure () is lowered down into the weak soils to a desired depth.
