HELICAL TIE-BACK ANCHORS
A helical tie-back anchor is a steel shaft with round helix plates that is used to reinforce foundation and retaining walls for lateral stability. When the anchor is rotated into the ground, the helix plates generate an axial thrust causing the helical tie-back to advance into the ground much like a screw into wood. With one end of the tie-back secured to the wall, the tie-back is rotated into the ground at an angle to stabilize the wall against lateral loads.
Ram Jack helical tie-back anchors are 2-7/8″ diameter sectional pipe piles. They are hydraulically rotated into the ground to a minimum embedment or torque specified by an engineer. The piles are manufactured from high strength carbon steel tubing into standard lengths of 3, 5 and 7 feet, with couplings on the ends to allow them to be connected together as necessary to achieve the desired length. They are coated with a polyethylene copolymer-based thermoplastic powder coating for corrosion protection.
