ABSTRACT:
A piling assembly, and a method of anchoring the piling, are provided for increasing resistance to pull-out of the piling. The assembly includes an elongated piling having first and second ends, and first, second, third, and fourth anchors, each anchor having a circumferential extent less than one-half the circumference of the piling. The anchors are attached to the piling so that the first and second anchors are opposite each other at a first position adjacent the piling first end, and third and fourth anchors are opposite each other at a second position adjacent the piling first end. The second position is a greater distance than the sum of the distance the first position is spaced from the piling first end and the axial length of an anchor. The third and fourth anchors are circumferentially displaced from the first and second anchors around the piling. Each anchor comprises a pocket member of rigid material having an open top communicating with a hollow interior, and closed bottom, sides and ends. The pocket member, including the hollow interior, decreases in cross-sectional area from the open top to the bottom, and a plurality of flutes are formed in a side of the anchor defining the open top. Each pocket member is defined by a plate and a hollow, open-based, truncated pyramid section extending along the plate. When the piling is driven into the earth, if an obstruction is encountered the piling is rotated until the anchor encountering the obstruction is no longer in line with the obstruction, and then driving is continued.
