Abstract
The present invention relates to an erosion prevention arrangement that assists in preventing erosion of a bank by moving water, for example along a seawall by dissipating kinetic energy of the moving water. The erosion prevention arrangement comprises a frame arrangement configured for containing energy dissipation members, the frame arrangement comprising one or more poles secured to one or more piles of an anchoring arrangement. A plurality of energy dissipation members is contained within the frame arrangement. The erosion prevention arrangement comprises a fabric layer extending at least partly along a surface of the bank and along a landward side of the frame arrangement, in use, and wherein the fabric layer is composed of a geotechnical fabric configured for preventing erosion of the bank. The fabric layer serves to prevent erosion of relatively fine soil and gravel from being eroded from the bank between the relatively large energy dissipation members. In this way, the bank will not be eroded out from under the energy dissipation members, which can create holes in the frame arrangement through which the energy dissipation members can be lost, thereby reducing the effectiveness of the erosion prevention arrangement.

Description of Embodiments It should be noted in the following description that like or the same reference numerals in different embodiments denote the same or similar features.
And erosion prevention arrangement according to a first aspect of the invention is generally indicated by the numeral 1000.
In one embodiment now described, there is provided an erosion prevention arrangement 1000. The erosion prevention arrangement 1000 is configured for preventing erosion of a bank 5000, such as a riverbank, or a seashore, by moving water such as a river, tidal water movement or waves.
The erosion prevention arrangement 1000 comprises a frame arrangement 1100, within which is contained many energy dissipation members 1200. The energy dissipation members 1200 are envisaged as being concrete blocks or boulders of a size that are movable by medium-sized earthmoving equipment.
The frame arrangement 1100 includes an anchoring arrangement 1110 for securing the erosion prevention arrangement 1000 to the bank 5000. The anchoring arrangement 1110 is preferably in the form of two parallel lines of piles 1120. One line of piles 1120 is preferably arranged to the waterward side, while one line of piles is arranged to the landward side. It is envisaged that each of the lines of piles 1120 will be driven into the ground either partway up the bank 5000, or proximate to the bank, and extending parallel to the bank. It is envisaged that the waterward side line of piles 1120 will be driven deeper into the ground than the landward side line of piles 1120, since this line of piles 1120 can be expected to have to deal with increased buffeting from moving water such as waves.
It is envisaged that the anchoring arrangement 1110 could be provided by alternative arrangements and/or formations, including the provision of concrete foundations or the like. However, these not preferred due to the complexities of installing these while being subject to issues such as tides, the collapsing of holes due to the ingress of water, and the like.
The frame arrangement 1100 further comprises interlocked poles 1130 that secured to the piles 1120, preferably by fasteners (not shown) such as nut and bolt arrangements. The interlocked poles 1130 and piles 1120 together with the bank 5000 form a cage arrangement 1140 for containing the energy dissipation members 1200. The interlocked poles 1130 are preferably composed of plastic pipes that have been filled with concrete. In one possible embodiment, the plastic pipes can include steel reinforcing bar (not shown) around which concrete has been set, in order to make the poles 1130 more resistant to bending. The applicant believes that poles 1130 will be resistant to ingress of seawater through micro cracks in the concrete, and will assist in preventing rusting of reinforcing bars within the concrete. Further, the poles 1130 will be resistant to bending, and to damage by water.
It is envisaged that in an alternative embodiment (not shown) frame arrangement could further comprise diagonally extending interlocked poles.
In the preferred embodiments shown, erosion prevention arrangement further comprises a fabric layer 1300 that extends preferably along a lower portion of the frame arrangement 1100, and along the landward side of the frame arrangement 1100. The fabric layer is preferably composed of geotechnical fabric, for example in the form of woven polypropylene material. The fabric layer 1300 preferably extends around, and is folded around some of the interlocking poles 1130 (as shown in figure 1).
The fabric layer 1300 serves to prevent erosion of relatively fine soil and gravel from being eroded from the bank between the relatively large energy dissipation members 1200. In this way, the bank 5000 will not be eroded out from under the energy dissipation members 1200, which can create holes in the frame arrangement 1100 through which the energy dissipation members 1200 can be lost, thereby reducing the effectiveness of the erosion prevention arrangement 1000.
In a preferred embodiment shown in figure 6, it is envisaged that the erosion prevention arrangement 1000 further comprise a walkway 1400 arranged along an upper portion operationally. It is envisaged that the walkway 1400 could comprise a series of elongate support members 1410 in the form of timber or concrete slabs arranged parallel to each other (as shown in figure 6). In an alternative embodiment, the walkway 1400 could be composed of poured concrete. In order to provide a poured concrete walkway 1400, it is envisaged that concrete could be poured directly onto underlying energy dissipation members 1200, or into moulds (not shown) built specifically for that purpose above the energy dissipation members 1200.
In this way, a scenic pedestrian pathway may be provided by the installation of a series of adjacent erosion prevention arrangements 1000.
Advantageously, it is envisaged that the frame arrangement 1100 will, together with the walkway, form an enclosed cage arrangement (shown in figure 6) containing energy dissipation members in a manner that prevents energy dissipation members 1200 from being moved by moving water acting on them.
It is envisaged that, in order to construct of the erosion prevention arrangement 1000, contractors will initially locate and install parallel lines of piles 1120 along the length of the bank 5000, preferably using a piledriver (not shown) having an extended reach. After this, the interlocking poles 1130 will be fastened to the piles 1120 fasteners.
The fabric layer 1300 will then be installed to cover the bottom and landward side of the frame arrangement 1100. After this, energy dissipation members 1200 will be used to fill up the space between the frame arrangement 1100 and the bank.
Lastly, a walkway can optionally be installed at or towards an upper portion of the frame arrangement 1100, for example by laying elongate members 1410 alongside each other and fastening the elongate members to the frame arrangement, or setting up moulds, and pouring concrete into the moulds.
Advantageously, as the energy dissipation members 1200 are effectively held in place by the frame arrangement 1100 in rough weather, relatively smaller size energy dissipation members 1200 can be used, which means that smaller size earthmoving equipment can be used to deliver and install the energy dissipation members 1200. In some embodiments, even manual labour could be used.
At the same time, the energy dissipation members 1200 will dissipate the energy in large waves or the like as it impacts on the erosion prevention arrangement 1000, to thereby prevent erosion of the bank 5000.
