Definitions

  • the present invention relates to a method, an apparatus and a kit of parts for mounting a pole or post into the ground.
  • FIG. 1 A first conventional technique for mounting a pole, for example a sign post, in the ground 12 is illustrated in Figure 1.
  • a hole 13 is dug in the ground where a pole 10 is to be placed.
  • a pole 10 is then placed in the hole 13 and the hole is back filled with concrete 11.
  • a problem with the above technique is that by digging a hole in the ground, the surrounding soil is disturbed and is allowed to relax. Before the hole is dug, the soil is compacted and reasonably stable; however, after digging, the surrounding soil becomes loose. Once the pole and concrete are placed in the hole, the soil surrounding the concrete may not give satisfactory support and the pole may be insufficiently fixed in the ground.
  • FIG. 2 A second conventional technique of mounting a pole in the ground is illustrated in Figure 2.
  • a pole 10 is driven into the ground 12 and the surrounding surface, and any gaps at the side of the pole, are filled with concrete 11.
  • this technique can save time as compared to the first conventional technique.
  • the second conventional technique suffers from other problems in that the pole can more easily be withdrawn by unauthorised persons as the pole has less weight and less side friction without the concrete mass.
  • the pole can more easily be withdrawn by unauthorised persons as the pole has less weight and less side friction without the concrete mass.
  • since concrete is used this suffers the same problems of cost and time for preparation and transportation.
  • the present invention has been made with the aim of solving the above problems, and it is an object of the present invention to provide a method for mounting a pole in the ground that is quicker, more sustainable by not involving concrete, is secured at the bottom to negate unauthorised withdrawal and enables a pole to be replaced conveniently, by providing a shoe attached to the bottom of the pole that includes retractable projecting means that are operable to engage with the ground when in a projecting state.
  • a method including the steps of: forming a hole in the ground using a hole forming means while inserting a mounting sleeve into the hole formed; withdrawing the hole forming means and leaving the mounting sleeve in the hole; affixing to the pole a shoe having at least one retractable shoe projecting means; inserting the shoe and pole into the mounting sleeve; and twisting the pole to engage the at least one shoe projecting means into the ground.
  • the method further includes the steps of: affixing a collar to the top of the mounting sleeve, and affixing the collar to the pole, to provide rigidity and weather proofing to the assembly.
  • the step of twisting the pole attaches the pole to the top of the mounting sleeve by means of a bayonet mount.
  • the at least one shoe projecting means is a spike (but a flange or other projection could be used).
  • the hole forming means is an eccentric auger, and withdrawing the auger includes withdrawing the auger in concentric mode.
  • the hole forming means may be a pile driver.
  • the step of inserting the shoe and the pole into the mounting sleeve includes the step of removing a protective band from the shoe to release tension in at least one shoe tension means (such as a spring that forces the spike to project from the shoe) mounted in the shoe.
  • the method includes the steps of: separating the collar from the pole; separating the collar from the mounting sleeve; twisting the pole, so as to release the spikes from the ground, and withdrawing the pole from the mounting sleeve.
  • an apparatus in accordance with a second aspect of the invention, includes a shoe including at least one shoe projecting means, wherein the shoe is adaptable for attachment to a pole and the at least one shoe projecting means is retractable and has a retracted state and a projecting state. In the projecting sate the shoe projecting means is operable to engage with the ground.
  • a kit of parts includes the shoe according to the second aspect and a mounting sleeve.
  • the mounting sleeve has an inside diameter large enough to allow passage of the shoe and a pole having the shoe attached thereto, when the at least one shoe projecting means is in the retracted state.
  • the inside diameter is smaller than that of the at least one shoe projecting means when the shoe projecting means is in the projecting state.
  • the kit further includes a collar operable to be affixed to the top of the mounting sleeve and to the to the pole. It may also include adhesive operable to affix the collar to the pole.
  • a pole is provided mounted in the ground.
  • a mounting sleeve surrounds the pole, the mounting sleeve having a lower end.

If an eccentric auger is used, the auger may be withdrawn in the concentric mode.

  • the spikes 22 will extend and engage the soil to a certain extent depending upon the force applied by the springs 24.
  • the pole 10 is then rotated so as to fully extend the spikes 22 into the ground soil and force the spikes 22 into the projected state, as shown in Figure 9E.
  • the collar 45 is placed around the pole 10, and attached to the shoulder 20a of the mounting sleeve 20. The collar 45 is then attached to the pole 10 using a resin adhesive 46 (see Figure 9F).
  • the following, procedure may be used.
  • the pole 10 may then be pulled out from the mounting sleeve 20 and a replacement pole 10 fitted in its place according to the steps described above.
  • the shoe 21 may be removed from the old pole and attached to the new pole, or the new pole may have a new shoe already fitted.
  • the embodiments described above provide the advantage that the soil is not allowed to relax since the mounting sleeve 20 is inserted as the hole is being made by the pile driver or auger 60. Because of this, a firm, sturdy method of mounting a pole in the ground has been described that will be very resilient to external effects, i.e. wind and rain, and should last a long time. In addition there is no need to use concrete, which would require a contractor mixing, or awaiting delivery of ready-mixed concrete, thus saving time and money.
  • the pole may be mounted into the ground easily and quickly with the minimal of additional tools, and may be accomplished by a single contractor in a short time.
  • a pole mounted in the ground can easily be removed if it becomes damaged, or removed for any other reason, by simply removing the collar, twisting the pole and withdrawing it. Again this process could be accomplished by a contractor quickly and with minimal equipment.
  • To replace a pole it is only necessary to remove the old pole, fix the shoe (either the old one or a new one) to the new pole and then insert this according to the method above. This allows for the replacement of poles to be achieved with minimal equipment and may be performed in a matter of minutes.
  • the process does not require significant on-site quality control as this is achieved through the use of power equipment and preformed items. This would lead to saving in costs and time in the mounting of poles, but also the time and expense in training contractors to carry out the process.
  • the new process may be more environmentally friendly since old concrete is not wasted each time a new pole is fitted, and the shoes can be detached from the old poles and reused on the new replacement pole.
