Helical Pile Capacity Chart

It is for quick reference only.

Helical pile capacity chart. Slope stabilization earth retention systems. The chart below details some of the piles that have been designed for past projects popular sizes and capacities. Large capacity helical piles have all of the advantages of traditional helical piers but are designed on a project specific basis and have higher capacities. Helical anchors inc is a manufacturer for helical pile helical piers and helical anchors.

They are based on dense granular soil a free head condition of the pile an above ground height of the piles of 150 mm 6 inches and with the application of only a lateral load. Q m σq h 2 1 where. The soil strength can be evaluated by use of various techniques and theories clemence 1985. With our superior patented inertia welding technology we provide the strongest piles in the industry.

The capacity of a helical anchor pile is dependent on the strength of the soil the projected area of the helix plate s and the depth of the helix plate s below grade. We have more than 25 years of experience in soil stabilization and earth foundation repair systems. The lateral capacity values are just indicative. The ultimate capacity of multi helix screw piles in compression and helical anchors in tension with a helix spacing diameter ration 3 is often taken as the summation of the capacities of the individual plates.
