APPARATUS AND METHOD FOR FASTENING A COMPOSITE POLE TO THE
GROUND
FIELD OF THE INVENTION
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
It is known to fasten composite poles in the ground by excavating a recess, and thereafter
positioning the ite pole in the recess and fill 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.
It is also known to mount a composite pole to a column raised from the . 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 bring the concrete to the position of the column often by use of a
helicopter, or make te at the position of the column. Both methods comprises extra
costs and work.

SUMMARY OF THE INVENTION
The invention has for its object to remedy or to reduce at least one of the drawbacks of
the prior art, or at least provide a useful alternative to prior art.
The object is achieved through features, which are ied in the description below and
in the claims that follow.
The invention is defined by the independent patent claims. The ent claims define
advantageous embodiments of the invention.
In a first aspect, the invention relates more particularly to fastening element in ance
with claim 1.
The ion concerns having a slit-formed opening, being circular, in the ground, where
a fastening element is positioned in the slit-formed opening. The fastening element has a
conical upper portion above the ground. A hollow composite pole, has a complementary
conical inner portion at its lower end, and is positioned on and abutting the fastening element.
The lower end portion of the fastening element is circular for allowing the fastening
element to be placed in the slit formed opening being circular, n the fastening element
is one-piece.
By hollow means that the composite pole must have an inner opening, at least in the portion
that is moved over the ing element.
The slit formed opening may be formed by ng or hammering a body into the ground.
The fastening element may be ed with drill elements at its lower end portion to enable
the fastening element to be used as a drill.
The drill elements may comprise metal or ceramic material or combinations thereof.
In a second aspect the invention relates more particularly to a method for fastening a hollow
composite pole for overhead power lines to the ground in accordance with claim 5.
The method comprises fixing the fastening element to the ground, for ce by adhesive
or a concrete based material.
The method may se making the slit formed opening by drilling into the ground.
James & Wells Ref: 309964NZ
The method may comprise making the slit formed g by hammering the fastening element
into the ground.
The method comprises providing the lower end portion of the fastening element with drill
elements and ng the fastening element into the ground.
The fastening element may be made from composite material or metal or combinations
thereof.
If parts of the ground that is positioned on the inner side of the slit should loosen or where
it is advantageous to have it removed partly or fully, the material on the inner side of the
slit may be at least partly removed.
When drilling in soil or march, it may be advantageous to have frost in the ground to avoid
movement in the ground during drilling.
Tests show that the drill or the fastening element must be aligned with the vertical axes
prior to being moved into the ground.
The apparatus and method according to invention solves the problem of ing a hol-
low composite pole to the ground in a relatively simple and cost effective way.

DETAILED DESCRIPTION OF THE EMBODIMENTS
On the drawings, the reference numeral 1 denotes a drill that by the help of a power drill 2
is under cement into the ground 4. The ground 4 may constitute for example rock,
soil, or march, alternatively combination thereof.
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,
ces 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.
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.
In an embodiment of the invention, shown in fig. 3, a sleeve formed fastening element 10
is positioned in the slit formed g 6. Additional fixing of the fixing element 10 to the
ground 4 may be carried out as described for the composite pole 8. A composite pole 8
that is conical inside is placed about the fastening element 10 that has a conical upper
n 18, and moved against the fastening element until nt is established.
In some cases, as when the ground 4 mainly constitutes suitable soil, the fixing element
10 may be forced into the ground 4 by hammering.
In a r alternative embodiment as shown in fig. 4, the fastening element 10 is by its
lower end portion 12 ed with several drill elements 14. The section IV-IV in fig 5
shows a possible distribution of the drill elements 14 about the centre axis 16 of the fastening
element 10. The drill elements may be made from material from the fastening ele-
ment 10 or constitute other materials that is fixed to the fastening element 10.
James & Wells Ref: 309964NZ
A typical drill element 14 is shown in fig. 6 where the drill element 14 that constitutes hard
metal, is braced to the in use lover end portion lower end n 12 of the fixing element
The fixing element 10 shown in fig. 4 is shown in two parts where in use an upper portion
18 that is fixed to the composite pole 8 is fixed to the in use lower portion 22 of the fixing
t 10 by a flange connection 20. The lower portion 22 is here drilled into the ground
It should be noted that the above-mentioned embodiments illustrate rather than limit the
invention, and that those skilled in the art will be able to design many alternative embodi-
ments without departing from the scope of the appended claims. In the claims, any reference
signs placed between parentheses shall not be construed as limiting the claim. Use
of the verb "comprise" and its ations does not exclude the presence of elements or
steps other than those stated in a claim. The article "a" or "an" preceding an element does
not exclude the presence of a plurality of such ts. The mere fact that certain
measures are recited in mutually different dependent claims does not te that a combination
of these measures cannot be used to advantage.
