Description
FIELD
[0001] Embodiments disclosed herein relate to helically driven
piles used in civil and utility applications.
BACKGROUND
[0002] It is necessary to place cable telephone and communications
equipment and electrical wiring in enclosures for protection from
the elements. Thus, it is known to use cabinets to protect
equipment and wiring for telephone and cable applications;
naturally, these cabinets need to be level and stabilized, and
hence concrete slabs must be poured and dried.
[0003] However, problems in the use of concrete slabs have arisen.
First pouring a suitable concrete slab is time consuming and labor
intensive. An appropriate bed must be dug out, gravel compacted and
cement mixed, poured skimmed, leveled, and dried. Often, further
settling or shifting of the soil bed (or the compacted stone) leads
to cracking of the slab and instability. Additionally, concrete may
not be level or may not be skimmed appropriately, leading to the
puddling of water and further damage to the concrete slab and
instability of the cabinet. Finally, concrete slabs at ground level
are susceptible to water damage caused by large puddles or flooding
of water. Furthermore, at ground level, cabinets are exposed to
snow drifts and corrosive salts and debris associated with road
maintenance and snow removal.
[0004] One solution to the problems posed by the use of concrete is
to attach cabinets to telephone and utility poles. Attaching
cabinets to existing poles elevates equipment and wiring and
thereby provides protection from flooding water, snow build up,
salts and other corrosives and debris associated with snow removal
along roads and thorough fares. The elevated positioning thus
solves some of the problems associated with the use of concrete
slabs but creates others. When housing equipment, the cabinets are
heavy, and put stress on utility poles which are typically made of
wood. Furthermore, cabinets are mounted on one side of the pole,
thereby creating an imbalance that pulls the pole from its proper
alignment in holding up overhead lines. Re-setting poles is
expensive and disruptive to electric telephone and cable
service.
[0005] Accordingly, there exists long felt need to protect
equipment and wiring from the elements quickly while at the same
time reducing labor costs. There also exists a need to provide a
stable environment for equipment without loading existing
infrastructure excessively. The present invention is directed to
overcoming these and other disadvantages inherent in prior art
systems. Other advantages will be revealed in the following
specification.

DETAILED DESCRIPTION
[0019] FIG. 1 depicts a preferred embodiment of a pile 100. As
shown therein, the pile 100 is provided with a pile axis 101 and
plurality of pipe ends 101, 102. As used herein the term "pile end"
is intended to include the extreme portion of the pile 100 as well
as portions extending therefrom. Disposed at one of the pipe ends
101, 102 is a plate 200, which is referred to herein as a "first"
plate 200 in order to distinguish it from other plates. The first
plate 200 is welded to the pile end 101. The plate 200 provided in
the presently preferred embodiment is in the shape of a disc that
is oriented to be generally orthogonal to the pile axis 111 and
provided with a generally flat outer surface 210.
[0020] The plate 200 is provided with a plurality of openings 210,
211, 212, 213, 220, 221, 222, 223, 230, 231, 232, 233. The openings
are in the form of a plurality of holes 210, 211, 212, 213, 220,
221, 222, 223 and slots 230, 231, 232, 233. The holes 210, 211,
212, 213, 220, 221, 222, 223 include a plurality of fastening holes
210, 211, 212, 213 that are straight-through holes and shaped to
accept a plurality of bolts (not shown). Also shown in FIG. 2 are a
plurality of tapped holes 220, 221, 222, 223 that are shaped to
accept grounding lugs (not shown).
[0021] The first plate 200 is configured to be attached to a
platform 300, which is depicted in FIG. 3. As shown therein, the
platform 300 is in the form of a plate (which will sometimes be
referred to as a "second plate" in order to distinguish it from the
"first" plate 200). The platform is shaped to cooperate with a
housing 400 and is provided with a plurality of openings (which
shall be referred to a "platform openings" in order to distinguish
them from other openings shown herein).
[0022] The platform 300 is provided with an upper surface 301 and
an under surface 302, a plurality of reinforcements 310, 311, 312,
and a plurality of sides 303, 304, 305, 306. As FIG. 5-a
illustrates, the sides 303, 304, 305, 306 are configured as
opposing pairs 303, 304, 305 and 306. One pair of sides 305, 306
are welded onto the platform while the other pair of sides 303, 304
are formed over the edges 307, 308 of the platform, as is depicted
in FIG. 4 and FIG. 5-a.
[0023] The reinforcements 311, 312 extend from one of the sides of
the platform to the other side (from one side 303 to the other
opposing side 304). The reinforcements 311, 312 are in the form of
channels spaced to provide the platform 300 with rigidity.
Advantageously, the channels are provided with a plurality of drain
holes that drain away water that may condense or seep therein. The
channels and the second plate 300 are also provided with a
plurality of mounting holes 320, 321, 322, 323, that are shaped to
cooperate with the holes 210, 211, 212, 213 on the first plate 200.
Because the reinforcements 310, 311, 312 are in the form of
channels, the fasteners (preferably mounting bolts) used to secure
the platform 300 to the plate 200 are recessed so that the upper
surface 301 presents a smooth and flat finish.
[0024] As noted above, the plate 200 is provided with at least one
slot, but preferably a plurality of slots 230, 231, 232, 233. The
slots are curved about a slot axis 201, which advantageously is
coaxial with the pile axis 111 after the plate 200 and the pipe are
welded together. The slots 230, 231, 232, 233 are dimensioned to
accept a fastener, which, in the preferred embodiment, is a bolt.
As FIG. 2 illustrates, the slots 230, 231, 232, 233 are provided
with a slot width 23.
[0025] The slots 230, 231, 232, 233 are oriented so that the
mounting bolts pass through the mounting holes 320, 321, 322, 323
in the platform 300, through the channels, to extend through the
slots 230, 231, 232, 233 in the first plate 200. Because the slots
230, 231, 232, 233 are curved about the slot axis 201, the platform
300 can be turned and oriented while the mounting bolts extend
through both the plate 200 and the platform 300. After the platform
300 is adjusted on the plate 200, the mounting bolts and nuts
secure the platform 300 to the plate 200. Thus, the platform 300 is
adjustably mounted to the pile 100. In the preferred embodiment,
each of the slots 230, 231, 232, 233 forms an arc of 30.degree..
Nonetheless, it is within the scope of the present invention for
each slot to form an arc that ranges between 0.degree. and
30.degree.. Collectively, the slots form an opening 235 that is
shaped as a circle with at least one, but preferably a plurality
of, interruptions 236, 237, 238, 239.
[0026] The plate 200 is also provided with an indicator 240, which,
in the preferred embodiment, is in the form of a notch 241 located
at the outer portion of the plate 200. As FIG. 2 reveals, the plate
200 is provided with a plurality of notches 241, 242. The indicator
240 (and hence each of the notches 241, 242) provides the installer
with a visual indication of the orientation of the pile 100. Thus,
the pile 100 can be helically driven into the earth and then, by
virtue of the indicator 240, aligned for the platform 300 to be
secured to the plate 200.
[0027] The platform 300 is preferably configured to cooperate with
electrical wiring and is provided with a plurality of wiring holes
(which have been designated collectively as "330" on FIG. 3). The
pile 100 itself is also configured to cooperate with electrical
wiring, and hence, is provided with a fixture 120 that is shaped to
retain a plurality of wires. As FIG. 2 illustrates, the fixture 120
and is provided with a first fixture end 121 and a second fixture
end 122 and is in the form of a channel that extends axially along
the outer surface of the pipe 130. The fixture 120 is provided with
pilot holes to accept a screw (not shown) so that a wiring strap
can be secured to the pile 100.
[0028] The pile 100 is also provided with a depth indicator 241. In
the preferred embodiment, the fixture 120 also provides a visual
indication of how far into the soil the pile has penetrated. The
fixture 120 is positioned axially on the pipe 130 so that one of
the fixture ends 121, 122 is located at a standard installation
depth (approximately 4.5 feet).
[0029] The pile 100 is provided with a lead 140, a pipe 130, and a
plate 200. The lead 140 is shaped to penetrate earth so as to
provide a foundation for the platform 300. In the preferred
embodiment, the lead 140 is a helix and welded to an end of the
pipe 130. The fixture 120 is also welded to the pipe 130, and as is
noted above, the plate 200 is welded to the pipe 130 as well.
Advantageously, the pile 100, the plate 200, and the platform 300
are provided with a coating to prevent corrosion, preferably hot
dipped and galvanized.
[0030] Referring again to FIG. 2, the plate 200 is a simple flat
steel plate, approximately 0.75 inches in width, that is cut and
drilled to provide the openings 210, 211, 212, 213, 220, 221, 222,
223, 230, 231, 232, 233. While the plate 200 included as part of
the preferred embodiment is generally flat with holes 210, 211,
212, 213 for attachment to a Kelly bar adapter, in an alternative
embodiment, the plate 200 is replaced with a connector 400 that is
in the form of a casting with a Kelly bar adapter integrated
therein. During installation, a Kelly drive is coupled to the pile
100 (either through attachment of a Kelly Bar adapter via the
installation holes or through use of the connector) and the pole
100 is torqued. The helical lead 140 enables the pile to be
"screwed" into the soil up to the depth indicator 241 thereby
ensuring that the pile 100 is driven to an appropriate depth. After
the pile 100 is driven into soil, the platform is adjustably
attached to the plate 200 (or connector 400, as the case may
be).
[0031] After the platform 300 is secured, an enclosure (generally
designated "500" in FIG. 9) is fastened to the platform 300 via a
plurality of enclosure holes (which are collectively designated
"340" in FIG. 3). Preferably, as shown in FIG. 9, a plurality of
enclosures 501, 502 may be fastened to the platform 300.
[0032] While this invention has been particularly shown and
described with references to embodiments thereof, it will be
understood by those skilled in the art that various changes in form
and details may be made therein without departing from the spirit
and scope of the invention as defined by the appended claims.
