SQUARE SHAFT HELICAL ANCHORS
In our last blog, Tip Of The Day, Brian dives deeper into the beneﬁts of a square shaft Helical Anchor.
The square shaft is typically solid and capable of large axial compressive loads. The shaft carries the load down through to the end of the pile, this is made possible because the solid shaft is continuous at each extension. Square shaft anchors can be used for a variety of the tension applications, but as Brian stated they are best used as anchors or tie backs. An advantage to having a square shaft is in rocky hard soils the square shaft leads are better at advancing with out damage in a lateral load. So we typically use these types of anchors on retaining walls and slopes.
