AI Technical Summary

Benefits of technology

The invention offers a way to attach a hollow composite pole to the ground in a easy and affordable way.

Problems solved by technology

Regarding poles for overhead power lines, such a method will often involve relatively large environmental damage, particularly when a recess is made in rock.
When fastening poles by use of said method, frost damage may occur due insufficient draining.
Both methods comprises extra costs and work.

Embodiment Construction

[0032]On the drawings, the reference numeral 1 denotes a drill that by the help of a power drill 2 is under displacement into the ground 4. The ground 4 may constitute for example rock, soil, or march, alternatively combination thereof.

[0033]The power drill 2 is typically aligned and is fixed to the ground 4 or another suitable, not shown device. There after the power drill 2 that may be electrically or hydraulically driven, displaces the drill 1 into the ground 4 while rotating the drill 1. Thus, a slit formed opening 6 is formed in the ground 4. The drill 1 is then removed from the slit formed opening 6.

[0034]A composite pole 8 that has been moved into the slit formed opening 6 is shown in FIG. 2. Additional fixing of the composite pole 8 to the ground 4 may be achieved by inserting grouting, fixing compound or other material (not shown) in between the composite pole 8 and the ground 4.

[0035]In an embodiment of the invention, shown in FIG. 3, a sleeve formed fastening element 10 i...

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.

Description

FIELD OF THE INVENTION[0001]This invention relates to an apparatus for fastening a hollow composite pole to the ground where a slit formed opening is present in the ground. The invention also relates to a method for fastening a hollow composite pole to the ground.BACKGROUND OF THE INVENTION[0002]It is known to fasten composite poles in the ground by excavating a recess, and thereafter positioning the composite pule in the recess and till in around the pole. Regarding poles for overhead power lines, such a method will often involve relatively large environmental damage, particularly when a recess is made in rock. When fastening poles by use of said method, frost damage may occur due insufficient draining.[0003]It is also known to mount a composite pole to a column raised from the ground. The column may be made from concrete and having reinforcement that extends into the ground. The composite pole may be inserted over the column. If the column is made from concrete, it is necessary to...
