Apparatus and Method for Fastening a Composite Pole to the Ground

Abstract

A fastening element is for fastening a hollow composite pole to the ground at a location where a slit-formed opening is present in the ground. The fastening element has a lower end portion that is configured for being positioned in the slit-formed opening, wherein a conical portion of the composite pole is abutting a conical upper portion of the fastening element. A method is for fastening a hollow composite pole to the ground.
