US 6,615,554 B2 · Helice pier coupling system used for soil stabilization

Abstract

A helice pier coupling system used for used for soil stabilization, supporting building structures and similar applications. The coupling system provides a way of adding one or more pier shaft extensions to a helice pier shaft of a helice pier for extending the length of the pier. The pier shafts may have lengths of 5 feet or greater. The coupling system includes a first helice pier. The first helice pier having diagonal cuts at a lower first end and an upper second end of a pier shaft. The lower first end of the pier shaft can be used as a lead point when the pier shaft is driven into the soil surface. The upper second end of the pier shaft can be used with a shaft coupling for engaging a lower first end, having a mating diagonal cut, of a pier shaft of a second helice pier or the pier shaft extension. The first helice pier includes one or more helice plates.
