Helical anchors consist of an assembly of steel shafts with a series of helical steel plates attached on a pitch to create a screw anchor. These steel anchors can be screwed into the ground to create foundation support, tie back wall systems and soil nail wall systems. It is screwed into the ground until there is enough torque resistance to indicate sufficient bearing strength. The capacity of a helical anchor in compression or tension is based upon the bearing capacity of the helices against the soil in which it is embedded. Therefore the capacity increases as the area of the helices is increased and as the soil friction angle increases. During installation, the torque resistance of the anchor is monitored and provides verification when the anchor capacity is achieved. It provides working/design compression and uplift capacity on the order of 30 to 100 kips depending on the soils encountered. The benefits of this system is that they eliminate the need for grout to set up to gain capacity, and eliminates disposal of spoils, which is especially important when installed in contaminated soils.
