Description

AUSTRALIA PATENTS ACT 1990
COMPLETE SPECIFICATION INNOVATION PATENT A MARINE PILE
The following statement is a full description of this invention:
A MARINE PILE TECHNICAL FIELD
[0001] The present invention relates to a marine pile.
BACKGROUND
[0002] The reference to any prior art in this specification is not, and should not be taken as an acknowledgement or any form of suggestion that the prior art forms part of the common general knowledge.
[0003] Marine piles are used for various purposes including: supporting wharves, jetties and boardwalks; restraining marina pontoons and canal pontoons; supporting jetties and floating pontoons at boat ramps; acting as fender piles in marina applications; and construction of navigation beacons around ports and harbours.
[0004] In practice, marine piles are made from concrete, steel or timber. The corrosive environment takes its toll on such piles which need to be replaced. Replacement is complicated by the weight of the piles.
[0005] The preferred embodiment provides a lighter, stronger and/or more durable alternative to known piles.
SUMMARY OF THE INVENTION
[0006] According to one aspect of the present invention, there is provided a marine pile including: an inner protective layer; a structural layer adjacent the inner protective layer; and an outer protective layer adjacent the structural layer; each layer being wound with filament and including epoxy vinyl ester resin, the structural layer having a different proportion of filament and resin than the inner protective layer and the outer protective layer.
[0007] Advantageously, the structural layer is sandwiched between the protective layers to facilitate durability. The pile may be tubular thereby making it lightweight compared with known solid piles. The pile may be more flexible than concrete, steel or timber alternatives.
[0008] The resin may include vinyl ester or epoxy vinyl ester. The filament may include e-glass or fibre glass
[0009] Each protective layer may be waterproof. Each protective layer may include at least 70% epoxy vinyl ester resin. Each protective layer may include at most 30% filament. Each protective layer may be at least 0.5 mm thick.
[00010] The outer protective layer may include a ultraviolet stabilizer. The outer protective layer may include a color pigment.
[00011] The structural layer may include at least 70% filament. The structural layer may include no more than 30% epoxy vinyl ester resin. The structural layer may have a wind angle of between 30 degrees and 60 degrees. The structural layer may have a thickness of between 10 and 30mm. The pile may have a diameter in the range of 100mm to 1200mm.
[00012] The marine pile may include a coating adjacent the outer layer. The coating may resemble existing piles in a structure, when retrofitting the pile.
[00013] According to another aspect of the present invention, there is provided a method for manufacturing a marine pile, the method including: forming an inner protective layer; forming a structural layer adjacent the inner protective layer; and forming an outer protective layer adjacent the structural layer; wherein each layer is wound with filament and includes epoxy vinyl ester resin, the structural layer being formed with a different proportion of filament and resin than the inner protective layer and the outer protective layer.
[00014] Any of the features described herein can be combined in any combination with any one or more of the other features described herein within the scope of the invention.
BRIEF DESCRIPTION OF THE DRAWINGS
[00015] Preferred features, embodiments and variations of the invention may be discerned from the following Detailed Description which provides sufficient information for those skilled in the art to perform the invention. The Detailed Description is not to be regarded as limiting the scope of the preceding Summary of the Invention in any way. The Detailed Description will make reference to a number of drawings as follows:
[00016] Figure 1 is a sectional view of a wall of a marine pile in accordance of an embodiment of the present invention;
[00017] Figure 2 is a characteristic showing the properties of a structural layer of the marine pile of Figure 1; and
[00018] Figure 3 shows exemplary load data for the structural layer of Figure 2.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[00019] According to an embodiment of the present invention, there is provided a tubular marine pile 100 with a wall cross-section as shown in Figure 1. The pile 100 includes an inner protective layer 102, a load-bearing structural layer 104 adjacent the inner protective layer 102, and an outer protective layer 106 adjacent the structural layer 104.
[00020] Advantageously, the structural layer 104 is sandwiched between the protective layers 102, 106 to facilitate durability. The pile 100 is tubular thereby making it lightweight compared with known solid piles. Furthermore, the pile 100 is more flexible than concrete, steel and timber alternatives.
[00021] Each layer 102, 104, 106 is wound and includes vinyl ester or epoxy vinyl ester resin. Each layer 102, 104, 106 also includes e-glass (or fibre glass) filament.
[00022] Each protective layer 102, 106 includes at least 70% vinyl ester or epoxy vinyl ester resin, and includes at most 30% filament. Each protective layer 102, 106 is at least 0.5 mm thick to ensure waterproofing so that the structural layer 104 is not exposed to moisture.
[00023] The outer protective layer 106 also includes an ultraviolet stabilizer, and can also include include a color pigment.
[00024] The sandwiched structural layer 104 includes at least 70% filament, and includes no more than 30% vinyl ester or epoxy vinyl ester resin. The structural layer 104 can have a wind angle of between 30 degrees and 60 degrees as indicated in Figure 2 to provide the right mix of strength and stiffness. A 30 degree wind produces a stiffer pile 100 than a 60 degree wind. A layer wall thickness of between 10 and 30mm provides loading as indicated in the tables of Figure 3. The pile 100 can a diameter in the range of 100mm to 1200mm.
[00025] In some circumstances, such as retrofitting the pile 100, the marine pile 100 may include a coating 108 adjacent the outer layer 106 which resembles existing piles in a structure. This layer 108 is a traditional marine coating applied post production essentially as an aesthetic enhancement or to match the new pile 100 into an existing structure. Coatings 108 such as Interzone and Marathon can be applied to the composite pile 100 and still exceed manufacturers pull off standards i.e. the paint yields before the surface bond.
[00026] The pile 100 is a far stronger and more durable product than known piles, better suited to the marine environment as it is inert meaning that vessels moored in close proximity will not suffer electrolysis damage to metal components. The structural pile 100 can be driven by means of hammer or vibration in the same way traditional timber, steel and concrete piles are installed. Advantageously, the pile 100 weighs half the weight of a steel pile of comparable strength which allows a pile driving barge of a set lifting capacity to drive bigger or longer piles than was possible before.
[00027] The pile 100 is formed in layers using a filament winding process. This process involves winding the filament under tension over a rotating mandrel. The mandrel rotates around the spindle (Axis 1 or X: Spindle) while a delivery eye on a carriage (Axis 2 or Y: Horizontal) traverses horizontally in line with the axis of the rotating mandrel, laying down the filament in the desired pattern or angle. This process is computer controlled to ensure that the filament is wound onto the mandrel at the correct angle and thickness for the design application. The most e-glass filament is impregnated in a bath with the vinyl ester or epoxy vinyl ester resin as it is wound onto the mandrel. Once the mandrel is completely covered to the desired thickness, the resin is cured. Depending on the resin system and its cure characteristics, often the rotating mandrel is placed in an oven or placed under radiant heaters until the part is cured. Once the resin has cured, the mandrel is removed or extracted, leaving the hollow final product.
[00028] According to the foregoing method, the marine pile is formed by first forming the inner protective layer 102, then forming the structural layer 104 adjacent the inner protective layer 102, and finally forming the outer protective layer 106 adjacent the structural layer 104. The coating 108 can be applied to the finished pile 100 if desired.
[00029] A person skilled in the art will appreciate that many embodiments and variations can be made without departing from the ambit of the present invention.
[00030] In compliance with the statute, the invention has been described in language more or less specific to structural or methodical features. It is to be understood that the invention is not limited to specific features shown or described since the means herein described comprises preferred forms of putting the invention into effect.
[00031] Reference throughout this specification to 'one embodiment' or'an embodiment' means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearance of the phrases 'in one embodiment' or'in an embodiment' in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more combinations.
