Abstract
An anchoring system for poles includes a support member having a tapered recess for receiving a tapered end of a pole and an anchor connected to the support member for securing the support member to a fixed surface. Preexisting poles can be rehabilitated by securing the pole in an upright position and then severing the pole near ground line. The pole is tapered near the bottom end and the bottom end of the pole is inserted into the tapered recess of a support member. The support member is then secured to a fixed surface such as an anchor member by anchor bolts for example.
Description
_ ~ CA 02269940 1999-04-21 HYDRO POLE ANCHOR APPARATUS AND METHOD
BACKGROUND OF THE INVENTION
This invention relates to a method and apparatus for anchoring poles, such as utility poles, and, in particular, for rehabilitating used poles.
Various types of earth anchors have been developed for poles or the like. An example is the pointed post support shown in United States Patent No. 4,271,646 to Mills.
This support has a square recess on the top for receiving a post.
A similar post is shown in United States Patent No. 4,644,713 to Lehman.
Canadian Patent No. 286,122 shows a detachable post anchor for use with highway marker posts.
This includes a spike-like projection and a rectangular base with a pointed projection.
While the prior art does reveal devices for mounting poles, it does not adequately address the problem of wooden utility poles which have become rotted at ground line. This is a problem frequently encountered in moist climates. As a result, the poles are usually replaced and the entire used pole is discarded despite the fact that the defect is chiefly at the ground line.
Fresh poles, whether of wood, concrete, metal or other materials, are relatively expensive.
There is also considerable labor involved in removing hydro or telecommunication lines from the used pole, erecting the new pole and reconnecting the lines and other attachments.
It is an object of the invention to allow the reuse of wooden poles, such as utility poles, which have become weak at the ground line.
It is also an object of the invention to allow poles to be reused without having to detach hydro and communication lines from the pole, while the poles are being rehabilitated.
It is a further object of the invention to provide an apparatus and method for rehabilitating hydro poles which is economical and long-lasting.
SUMMARY OF THE INVENTION
According to the invention there is provided an anchor for poles which includes a member having means for receiving a pole having a tapered end. There is means connected to the member for securing the member to a fixed surface. For example, the means for receiving may include a conical recess in the member.
There is also provided, according to the invention, a method of erecting poles. One end of a pole is tapered. The pole is erected and the one end of the pole is inserted into a tapered recess in an anchor.
There is also provided, according to a further aspect of the invention, a method of I 5 rehabilitating utility poles. The poles are severed at a point near the ground line. One end of the pole, which is adjacent to the point, is tapered. The one end of the pole is inserted into an anchor with a complementary tapered recess.

BRIEF DESCRIPTION OF THE DRAWINGS
In the drawings:
Fig. 1 is a top, front isometric view of a combination utility pole and support system according to an embodiment of the invention, the utility pole being shown in fragment and the support system being partly broken away; and Fig. 2 is an exploded view of a support system for poles according to an alternative embodiment of the invention.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring first to Fig. 1, this shows a support system 10 for a utility pole 12. It should be understood however that the invention is applicable to other types of poles or the like. The support system includes an anchor 14 which has a frusto-conical support member 16. The member 16 has an internal frusto-conical recess 18 which serves as means for receiving tapered end 20 of pole 12. There is a flange 22 connected to bottom 24 of the frusto-conical member which is circular in shape in this embodiment. This serves as means for connecting the member 16 to a fixed surface.
In this particular example, the fixed surface is an upper surface 30 of an anchor member 34 which is typically buried in the ground. The anchor member has a flange 36 on its top 38 which is complementary in configuration to the flange 22 on the support member 16. Bolts 40 pass through complementary apertures in the two flanges to secure the members 16 and 34 together.
Fig. 2 shows a support system 10.1 which is generally the same as the previous embodiment.
The support member 16.1 is shown without a pole. Also, apertures 50 in flange 22.1 are visible. In this case anchor member 34.1 is a concrete block. The actual size would likely be larger than illustrated. It has four spaced-apart anchor bolts 50 which extend upwardly from top surface 30.1. These pass through the apertures 50 in the member 16.1 and nuts are applied to the ends of the bolts to secure the members together.
In use, the anchor system is typically employed to rehabilitate utility poles, such as hydro poles. These poles deteriorate most rapidly at ground level as is well known.
In the past the usual approach has been to completely remove such rotted poles and replace them with new poles of wood, concrete or other materials. However the invention offers a method for rehabilitating utility poles which is much simpler and less expensive. First, the pole can be temporarily secured by various means, such as a feller buncher of the type usually used for harvesting trees. These allow the utility pole to be clamped in an upright position and severed where desired. For example, a suitable unit is sold under the trademark UNIVER\SAW by Peninsula Design & Fabricating, Inc. of Stephenson, Michigan, USA.
Once the preexisting pole has been secured in position and severed near ground line, the stub of the pole remaining in the ground can be excavated and removed. In its place, a suitable anchor member, such as either of the types disclosed above, can be positioned.
The bottom end of the pole is tapered to the shape shown in Figure 1. This can be done manually using an ax, for example, or using a conical cutter similar to a large pencil sharpener. This can include a cage holding a mechanism like a pencil sharpener. It is mounted vertically on a turntable base which is hydraulically clamped to the bottom end of the pole.
When the turntable rotates, a knife held at a suitable angle tapers the pole. Hydraulic power may be supplied by a small, portable gas-powered pump or connected by a quick coupling to another machine at the site.
The tapered end of the pole in inserted into frusto-conical member 16 or 16.1 and the member is then secured to the anchor. Once this is completed, the pole can be released and is securely held in its original position. Holes may be drilled through the member and lag bolts inserted through the holes and into the pole if desired, for example if the pole is in a ravine and utility wires exert a lifting force on the pole.
The invention is also applicable to positioning new poles, rather than rehabilitating existing poles. In addition, other types of anchors can be utilized. For example, the member 16 of Figure 1 can be secured to a natural rock bluff by anchor bolts extending trough the flanges and into the rock of the bluff. In such cases excavation is not necessary to locate utility poles. Other man made anchors may be used such as preexisting concrete foundations.
Optionally there may be a trough extending about the tops of recesses 18 and 18.1 to receive a sealant such as a tar-like substance or caulking and wood preservative.
