Description

GABION CONTAINMENT APPARATUS

This invention r&ates to a gabion containment apparatus and in particular to improvements in and relating to storing and/or deploying gabions.

Gabions are generally structures of the type which comprise &de waD panels, end panels and partition panels which connect the wall panels, and aD the panels are usuafly rectangular and may be pivotally attached, connected together so that the structure can be moved between an expanded (or deployed) condition for use and a collapsed (or folded) condition for storage and transport. In the deployed condition, the structure is elongated and the panels define a row of cavities extending in the length direction of the structure, each cavity being defined by side panels and partition panels, apart from the end cavities which are defined by side panels, partition panels and end panels. These cavities can be filled with ballast or building materials so that the structure turns into a robust wall which can be used for defences for flooding, for military equipment and personnel, and for shoring of hillsides and river banks and the like, or simply as a property or other boundary. They can be used side-by-side, end-to-end or in superimposed relationship, depending upon the use to which they are to be put.

In the folded condition, the structure is basically flat and the partition and end panels lie in parallel planes, whilst the side panels of each side are folded one relative to another in zig-zag or concertina fashion, so that the plan footprint of the coflapsed structure is rectangular.

It is to be mentioned that when reference is made to "rectangular" herein, square, which is one form of rectangle, is specificaHy to be included.

An example of a structure of the type set forth is Ulustrated in European Patent No. 0 466 726 Bi in Figs. 1 and 2 thereof, and an accompanying description is also included in that Patent.

Gabions have been used throughout the world for many thfferent uses, and often in situations where rapid deployment (to prevent flooding, or protect against hostile forces, for example) is necessary. One advantage of the pivotaHy attached, connected multi-compartmental gabions described in EP-B-0466726 is that they can be easily and quickly erected, and can be tiDed with readily available and inexpensive materiaL especially in those embodiments, as described in said European Patent, where the panels are of mesh and have a lining material of gee textile to prevent particles of the filling material from falling through the holes of the mesh. This mesh and lining material construction is the preferred form for the present invention, but the invention is not limited to this particular form.

Heretofore, gabions have been supplied on pallets and In stacks, often wrapped in shrink wrap plastics material. Whilst this has been satisfactory and will we believe continue to be satisfactory especially for smaller sizes of gabion, with the larger gablons, the removal of the shrink wrapping, the removal of the gabion from the pallet takes time, and in emergency situations, time is of the essence, and the more time which can be saved in erecting defence walls, the better.

WO 2008(081177 describes a gabion deployment system comprising a container for retaining a gabion in a folded configuration and from which the gabion can be deployed. Whilst this has been satisfactory and will we believe continue to be satisfactory, the container Itself may be bulky and/or heavy and require a large amount of space in a storage facility and/or in a transport vehicle. Also, once the gabion has been deployed from the container, a user is left with an empty container which must be disposed of.

This Invention seeks to achieve an Improvement in thIs area, and to provide a means whereby the storage and/or transport of gabions can be achieved without the disadvantages of the present methods.

According to an aspect of the invention, there is provided a gabion containment apparatus for storing a folded multi-compartment gabion and from which the gablon can be deployed, the containment apparatus comprising: a base element for supporting the folded multi-compartmental gablon, the base element comprising a first member configured to extend along at east a part of a first side of said folded multi-compartment gabion, and a second member, extending transversely from said first member, said second member configured to extend along at east a part of a second side of said folded multi-compartmental gabion; and at least one retaining &ement, coupled at a first end thereof to said base element, said at east one retaining element being releasably attached, connected or retentively engaged, at least at one point of said at least one retaining element, by way of at least one releasable attaching, connecting or retentive engaging means, to a portion of a compartment of said folded multi-compartment gabion, said at least one retaining element configured to extend from said base element, over at least a portion of said folded multi-compartment gabion, said at least one retaining element serving to attach, connect or retentively engage a part of the gabion to the base element when the gabion is folded but to release the gabion from the base element when the gabion is deployed.

According to another aspect of the present invention, there is provided a gabion of the type comprising: hingedly attached, connected sidewalls and cross-members such that it can be folded for storage and deployed for use; and at least one releasable attaching, connecting or retentive engaging means suitable for attaching, connecting or retentive engaging the gabion to at east one retaining element of a gabion containment apparatus as described above and hereinafter; wherein the at least one releasable attaching, connecting or retentive engaging 4.

According to another aspect of the present invention, there is provided a palletised multi-compartmental gablon comprising pivotally connected side and end walls and at least one partition wall each having first and second ends defining respectively a top and a bottom of the palletised gabion, the gabion being mounted on its bottom on a pallet and secured thereto by means of a tether extending from the pallet over an end wall of the gablon and across at least a portion of the top of the gablon and frangibly or releasably secured thereto.

The at least one retaining element may be releasably attached, connected or retentively engaged, by way of said at least one releasable attaching, connecting or retentive engaging means, at a plurality of spaced intervals to a portion of a

S

respective plurality of indMdual compartments forming said folded multi-compartment gabion.

Elements of the base element and/or at least one retaining &emerit are optionally manufactured of tough and/or strong and/or durable materials (e.g. metal or plastics).

OptionaRy, the gabion containment apparatus may have dimensions such that it is readily transportable on a paflet, such as a pallet of dimensions 2 metres x 22 metres. Further optionally, an element of the gabion containment apparatus may comprise a pallet.

The at least one retaining element may comprise an elongate member, and may optionally comprise for example, at least one of a bar, cable, rope or strap or any other suitable form of restraint. Parts of the gabion can be releasably attached, connected or retentively engaged to the elongate member. Further optionally, the retaining element may comprise a tether, which tether may be frangibly or releasably secured to the gabion sequentially at a plurality of locations.

Optionally, the respective locations may correspond to different compartments of the multicompartmental gabion.

It is envisaged that, for example, when a multicomparimental gabion comprises five compartments, the folded gabion will be stored/transported in a gabion

U

containment apparatus provided with four releasable attaching, connecting or retentive engaging means. A first releasable attaching, connecting or retentive engaging means may be situated to couple the at least one retaining element to a side wail between first and second compartments of the gabion. A second releasable attaching, connecting or retentive engaging means may be situated to couple the at east one retaining element to a side wall between second and third compartments of the gabion. A third releasable attaching, connecting or retentive engaging means may be situated to couple the at least one retaining element to a side wall between third and fourth compartments of the gabion. A fourth releasable attaching, connecting or retentive engaging means may be situated to couple the at least one retaining element to a side wall between fourth and fifth compartments of the gabion, However, it should be emphasised that this is by way of example only, and each releasable attaching, connecting or retentive engaging means may be situated to couple the at least one retaining element to a different part of the gabion than the side wall between adjacent compartments.

Also, greater or fewer releasable attaching, connecting or retentive engaging means may be provided as required.

Optionally, the base element may comprise an L-shaped member.

I

The at least one releasable attaching, connecting or retentive engaging means can be of any suitable type. It is anticipated that suitable releasable attaching, connecting or retentive engaging means may comprise, amongst others: A folded gabion compartment edge section * A frangible oop or ring * A frangible part of the gabion A deformable member * A helical member; * A releasable Une; * A dip; A frangible coupling on, or part of, said at east one retaining element; and * A frangible portion of said at least one retaining element.

Where the releasable attaching, connecting or retentive engaging means is frangible, a point of weakness, such as a notch or groove may be provided to encourage the attaching, connecting or retentive engaging means to break at a predetermined position and/or load.

Any suitable type of clip may be used, such as a karabiner-type cUp or a sprung-cam type clip.

The at least one releasable attaching, connecting or retentive engaging means is adapted to attach, connect or retentively engage a part of the gabion to the at least one retaining element when the gabion is folded but to r&ease the gabion from the retaining means when the gabion is deployed.

The at least one retaining element may be designed so that the releasable attaching, connecting or retentive engaging means is provided by the gabion itself, or by a section thereof. In this sense the attaching, connecting or retentive engaging means is r&easable in the sense that it is capable of being released from the retaining element. In other embodiments the attaching, connecting or retentive engaging means may also or instead be releasable from the gabion itself.

The releasable attaching. connecfing or retentive engaging means is preferably adapted to break (where it is frangible), disconnect (where it is a clip), or deform (where it is deformable) at a predetermined load, or to break or deform the retaining element of the gabion containment apparatus at a predetermined load, Optionally, the releasable attaching, connecting or retentive engaging means is adapted to break and/or release a part of the gabion when loaded by an applied force (e.g. hand or machine-assisted pulling).

Optionally, the base element is configured such that the apparatus can be stored and/or transported and/or a gabion deployed therefrom with the first member in a lowermost position, and/or such that the apparatus can be stored and/or transported and/or a gabion deployed therefrom wfth the second member in a lowermost position.

One or more embodiments of the invention are described further hereinafter, by way of example only, with reference to the accompanying drawings in which: Fig. I shows a schematic view of a prior art sing'e unit gabion; Fig. 2 shows a schematic view of a prior art multiple unit gabion in a folded configuration; Fig. 3 shows a schematic view of a prior art multiple unit gabion in a deployed configuration; Fig. 4 shows a schematic prior art container gabion deployment system of a first type; Figs. 5a, Sb and Sc, 6 and 7 show schematic prior art container gabion deployment systems according to a second type; Fig. 8 shows a schematic gabion containment apparatus according to the present invention; Figs. 9a to 9c show schematically a deployment of a gabion from the apparatus illustrated in Fig. 8; Fig. 10 iflustrates a perspective view of the gabion containment apparatus of Fig. 8 mounted on a paHet; I0 Fig. ha shows schematic gabion containment apparatus according to the present invention in a particular orientation for storage and/or transport and/or deployment; Figs. I lb and lie show schematically a deployment of a gabion from the apparatus illustrated in Fig. ha; and Figs. 12 to 16 show side views of releasable attaching, connecting or retentive engaging means.

Turning now to the drawings, Fig. I shows a schematic view of a prior art single unit gabion 10, which comprises a pair of spaced-apart end walls 12 that are hingedly 14 connected to side walls. The side walls comprise two panels each 16 and 18 that are hingedly connected to one another 20 as well as to the end walls 14. Alternative gabion designs suitable for use with the present invention comprise single-pan& side walls. Side walls comprising more than two panels are also contemplated within the scope of the invention.

Each wall 12, 16 & 18 is constructed from a wire mesh. The hinge connections 14 & 20 are typically helical wire members that engage corresponding edge wires of adjacent walls 12, 16 & 18. The hinges 14 & 20 are sometimes separable from the walls 12, 16 & 18 (for which see our previous application GB0424321.8). Different configurations are possible, such as providing side walls constructed from substantially closed panels rather than mesh panels.

I

Turning now to Figs. 2 and 3, a prior art multiple-unit gabion is shown 22.

The construction is similar to that shown in Hg. 1 with side waUs 16 & 18 and an end wail 12 constituting a repeat unit that can be added as many times as necessary to produce a gabion 22 of desired length.

The gabion 22 can be stored in a folded configuration (Fig. 2) and extended to a deployed configuration (Fig. 3) by applying a tensile force as indicated by Arrows A. Conversely, the gabion 22 can be folded by applying a compressive force in the opposite sense to Arrows A. Once deployed, a gabion can be filled with any suitable fill' material (e.g. rocks, sand, earth, ice etc.) to produce a wail-type structure. Gabions generally have a liner (not shown) made of a sheet material to inhibit egress of filflng material through the holes in the mesh.

In Figs. 4, 5, 6, 7, 8 and ha a gabion 22 is represented by showing only a succession of end walls 12 for clarity. The side walls are represented by dotted Unes, which show that the end walls 12 are attached connected to one another. In Figs. 9a to 9c, 11 b and lie, folded portions of a part-deployed gabion 22 are represented by showing only a succession of end walls 12 for clarity. However, deployed portions of the part-deployed gabion 22 illustrated in Figs. 9a to 9c, lib and lie are represented showing end waIls 12, panels 16, 18o1 side walls, and hinges 20. s..

One conveiient way of transporting gabions 22 Is in containers as illustrated by Fig. 4. A container 30 generally comprises a base 32, side and end walls 34 and a roof 36. The base 32 has apertures tabs 38 that engage with pins provIded (in this case) on a lorry 42. The container 30 has eyelets 44 to enable It to be loaded onto and off the lorry 42 using a crane (not shown).

The gabion 22 is deployed by pulling on the first end wall 12' as indicated by Arrow B such that the gablon extends, usually in a unit-by-unit manner. The pull B can be effected by pulling on the end wall 12', holding the end wall 12' and driving the lorry in the direction indicated by Arrow C or a combination of both.

A major problem with transporting and deploying gabions 22 in this manner is that when the gabion 22 is to be deployed on inclined ground 46, there is a tendency for the gablon 22 to topple out of the container 30. Because the various parts of the gablon 22 are attached or connected to one another 48, once it has begun toppling, a large part, If not all of the gabion 22 is likely to spill out onto the ground behInd the lorry 42. This can be extremely hazardous to persons nearby. A further problem is that the gabion 22 can become tangled or break, which can be inefficient, wasteful, and time-consuming to rectify.

Another known way of transporting gabions 22 in containers is iflustrated in Figs. 5a to 5c, with known methods of deployment in Figs. 6 and 7. In Hg. St a container 30 is shown having a roof 36. From opposite ends of the underside of the roof 36 depend eyelets 37 to which a retaining means in the form of a retaining cable 50 is attached, connected by way of snap hooks 39.

End walls 12 of the gabion 22 are attached or connected to the retaining cable 50 by way of discontinuous rings 66.

The retaining cable 50 prevents the gabion 20 from spifling out of the container 30 without the attaching, connecting or retentive engaging rings 66 first being broken or deformed.

In Fig, 5b it can be seen that each end wafl 12 is provided with a pair of attaching, connecting or retentive engaging rings 66 for attaching, connecting or retentive engaging to a pair of spaced-apart and substantially parallel retaining cables 50.

It is possible to provide non-parallel support cables 50 such that the gabion 22 becomes more difficult to slide therealong as it approaches the door of the container 30.

In this prior art arrangement, gabion 22 may have been factory-assembled, provided with attaching, connecting or retentive engaging rings 66 and folded.

One or more support cables 50 are threaded through the attaching, connecting or retentive engaging rIngs 66 and clip fasteners 39 attached, connected or retentively engaged to ends of the cable or cables 50. The gabion 22 is then loaded into a contaIner 30 and the dip fasteners 39 attached, connected or retentively engaged to roof eyelets 37.

In Fig. Sc, the contaIner 30 has a retaining means 50 dIsposed on the underside of the roof 36. The retaIning means comprises an attachment 52 to which a retaining cable 54 is attached, connected or retentively engaged. An extendible/retractable attachment 56 is attached, connected or retentively engaged to the other end of the retaining cable 54. The extendible/retractable attachment 56 comprises a support bar 58 that Is slidably engageable with a sheath 60. An end-stop 62 is provided to prevent the support bar from sliding beyond a desired extent. The support bar 58 depends from the sheath 60 and has an undulation 64 therein to inhibit movement of the gabion 22 thereaiong.

Associated with each end wall 12 of the gabion 22 is a releasable attaching, connecting or retentive engaging means 66 that connects respective end walls 12 of the gablon 22 to either the retaining cable 54 or the support bar 58. The height of the retaIning cable 54 and support bar 58 is such that the majority of the weight of the gablon 22 Is supported by the floor of the container.

In use, as iflustrated by Fig. 6, the door of the container 30 is opened and the first end waR 12' of the gabion 22 pulled in the dftection indicated by Arrow D. The support bar 58 slides beyond the periphery 68 of the container 30 such that a part of the gabion 22 is suspended beyond the periphery 68. The support bar 58 is prevented from disengaging the sheath 60 by virtue of the end-stop 62.

The releasable attaching, connecting or retentive engaging means 66 can be configured to disconnect 66 under the weight of a part of the gabion or to disconnect when an additional force E is applied thereto. Thus, the gabion 22 can be deployed unit-by-unit by a user (not shown) by first puthng a desired number of units out D, then pulling down E to release a desired number of units of the gabion 22. If the releasable attaching, connecting or retentive engaging means 66 are configured to disconnect under just the weight of the gabion 22, then the user need only pull the first unit out 0 and the rest wifl follow if the lorry 42 is advanced F. Fig. 7 shows how the gabion neither deploys nor spills out of the container 30 when the lorry 42 is on inclined ground 46. The releasable attaching, connecting or retentive engaging means 66 are configured to support the weight of the gabion 22 thereby preventing it from spilling out unless an additional force E is applied. Furthermore, the undulation 64 in the support bar 58 limits the number of gabion units that advance beyond the periphery of i6 the container 30, thereby limiting the cad on the releasable attaching, connecfing or retentive engaging means 66 to prevent additional forces E from being applied thereto.

A problem with storing and/or transporting gabions 22 in the manner iHustrated in Figs. 5a to 5c, 6 and 7 is that the container 30 adds to the weight and size of the material to be stored/transported when the gabions 22 are in a folded configuration. Also, once a gabion 22 has been deployed from container 30, a user is left with an empty container 30 with which the user may need to dispose.

Various versions of the invention are iflustrated in Figs. 8 to 11 of the drawings.

A gabion containment apparatus 80 according to the present invention is illustrated in Fig. 8.

The gabion containment apparatus 80 comprises a bracket 82 upon which the gabion 22 is located. The bracket 82 comprises a first plate 84 which comprises a member extending beneath the gabion 22 to support the gabion during storage/transport/deployment. A second plate 86, comprising a member extending transversely from an end of the first plate 84 is arranged to support an end of the gabion 22. The first and second plates 84, 86 are arranged in an Lshape configuration to form bracket 82.

In the illustrated arrangement, first and second plates 84, 86 comprise &ongate members. However, this need not be the case, and the first and second plates 84, 86 may comprise wider or narrower members as appropriate.

A retaining element comprising a retaining strap 88 is coupled, by way of coupling element 90, to an end of second plate 86 remote from the region where second plate 86 joins first plate 84. In the illustrated arrangement, the retaining strap 68 extends upwardly from the end of second plate 86, over a top end-edge 91 of the gabion 22, and across a top surface of gabion 22.

The retaining strap 88 is releasably attached, connected or retentively engaged to the top surface of gabion 22 at least at one point along the length of the strap. In the illustrated arrangement of Fig. 8, the retaining strap 88 is releasably attached, connected or retentively engaged to the top surface of gabion 22 at four points along its length by releasable attaching, connecting or retentive engaging means 92, 94, 96, 98 respectively. In a particular arrangement, releasable attaching, connecting or retentive engaging means 92, 94, 96, 98 releasably attach, connect or retentively engage the retaining strap 88 to respective end walls of single unit gabions forming the multiple-unit gabion 22. However, in other, optional, arrangements, the releasable attaching, connecting or retentive engaging means 92, 94, 96, 98 may releasably attach, connect or retentively engage the retaining strap 88 to any suitable portion of single unit gabions forming the multiple-unit gabion 22 In the arrangement illustrated in Fig. 8, the retaining strap 88 extends over a portion of the top surface of gabion 22 only. However, in an optional arrangement, the retaining strap 88 may extend over the entire top surface of gabion 22 and, optionally, may extend over another top end-edge 93 of gabion 22 (opposite top end-edge 91) and extend downwardly therefrom to be coupled to an end of first plate 84 remote from the point it meets second plate 86.

The retaining strap 88 and the bracket 82 serve, in combination, to prevent the gabion 22 from spilling, falling, or being inadvertently deployed from bracket 82 without the releasable attaching, connecting or retentive engaging means (hereinafter "engaging means' for brevity) 92, 94, 96, 98 first being broken or deformed.

Although only one retaining strap 88 is illustrated in Fig. 8, optionally, multiple retaining straps may be provided in one or more of the above described configurations with respect to the gabion 22 and the bracket 82.

It is envisaged that the gabion containment apparatus 80 will be assembled in the manner iuustrated in Fig. 8 in a factory. The gabion containment apparatus 80 may then be loaded onto a suitaNe transport vehicle for conveyance to a location at which it is to be deployed. The gabion 22 may be deployed from the folded state iUustrated in Fig. 8 directly from the transport vehicle to a deployed configuration. Optionafly, the gabion containment apparatus 80 may be unloaded from the transport vehicle and deployed from the gabion containment apparatus 80 located at ground level, or some other base level.

Figs. 9a to 9c illustrate steps in a deployment process.

In Fig. 9a, a first end wall 12' of the gabion 22 is pulled in the direction indicated by arrow 0. This causes at east one single unit gabion 10 of the gabion 22 to deploy from the gabion containment apparatus 80. Continued application of force in the direction indicated by arrow 0 causes further single unit gabions 10 of the gabion 22 to be deployed from the gabion containment apparatus 80 until a point is reached where the applied force is transferred through the deployed single unit gabions 10 to an outermost single unit gabion to which the retaining strap 88 is coupled via engaging means 98.

From that outermost single unit gabion, the applied force is transferred to the engaging means 98 itself.

The engaging means 98 is configured to disconnect 98' under continued application of force in the direction of arrow G. This causes the outermost single unit gabion to which the retaining strap 88 is coupled to be released from the retaining strap 88 and aHows deployment of that single unit gabion.

Continued application of force in the direction indicated by arrow G causes further engaging means 92, 94, 96 to disconnect 96' (Fig. 9b). 94', 92 (Fig. 9c) sequentially in the sequence 96, 94, 92 until the gabion 22 is free from the retaining strap 88 such that it can be pulled from the bracket 82 entirely (Fig. 9c). Thus, from the position illustrated in Fig. 9c, the gabion 22 is free to be fully deployed. This may be by continuing application of force indicated by arrow G to pull the gabion 22 free from the bracket 82 and/or may be by applying an additional force in a direction opposite to that indicated by arrow 0 to pull the bracket 82 from beneath the folded/part-folded portion of the gabion 22.

In an optional deployment arrangement, the bracket 82 may be used as a "skid" from which the gabion 22 can be deployed from the folded configuration (Fig. 8), through the part-deployed configurations illustrated in Figs. 9a to 9c, to a fully deployed configuration.

In this optional deployment arrangement, at east one outermost (i.e. remote from second plate 86) single unit gabiori of gabion 22 may be pulled to extend the at least one outermost sIngle unit gabion to a fully deployed configuration.

Fill material may then be added to this single unit gabion. This serves to anchor an end of the gabion 22. A deployment force may then be applied in a direction opposite to that indicated by arrow G in Figs. 9a to 9c to pull the bracket 82 away from the anchored end of the gabion 22. Such a force may be applied by attaching a coupling element such as a chain, rope. etc. betwccn bracket 82 and a suitable towing vehicle and then advancing the vehicle in a direction opposite to that kidicated by arrow G. This serves to pull the bracket 82 and folded portion of gabion 22 away from the anchored end of the gabion 22. Release of the folded portion of gabion 22 from retaining strap 88 then occurs in a similar manner to that described in relation to Figs. 9a to 9c.

Fig. 10 illustrates a top-perspective view of the gabion containment apparatus situated on a pallet 100. This arrangement may allow for convenient movement of the gabion containment apparatus 80 by, for example, a fork-lift truck or pallet truck Optionally, the gabion 22 may be deployed directly from pallet 100 using one of the methods descilbed above, In the illustrated arrangement, an upper surface of pallet 100 is provided with guide runners 102, 104 which are located adjacent edges of the pallet upper surface and which are configured to inhibit lateral movement of the gabion containment apparatus 80 rSative to the pa Vet 100.

An optional gabion containment apparatus 80 storage and/or transport configuration is iflustrated in Fig. ha and an option& deployment method from the storage and/or transport configuration is illustrated in Figs. llb and 11 C. n the optiona' configuration iflustrated in Fig. ha, the gabion containment apparatus 80 is oriented such that the second plate 86 forms the base of the gabion containment apparatus 80 in a normal orientation.

This configuration may be convenient to optimise space in a storage/transport facflity and/or during storage/transport in a vehicle. As will be appreciated from Fig. lot the footprint of an end of the gabion containment apparatus 80 is smaller than the footprint of the base of the gabion containment apparatus in the orientation iVustrated in Fig. 10. By orienting the gabion containment apparatus 80 on its end! the space required for the gabion containment apparatus during storage/transport may be reduced.

Further, in this configuration, the gabion 22 may become compressed under its own weight and so may not extend as far along first plate 84 as it does in the configuration iflustrated in Fig. 10. This may aVow additional single gabion units to be added to the gabion 22 on the gabion containment apparatus 80. It will be appreciated, therefore, that the capacity of the gabion containment apparatus may be increased to carry a gabion 22 comprising more single unit gabions using this configuratbn.

The gabion containment apparatus 80 illustrated in Fig. ha is simHarto that described in relation to Figs. 8 to 10, and ike reference numerals denote common features. The gabion containment apparatus 80 differs from the earher described apparatus by way of a curved lip 106 at a remote end of first plate 84 which serves to assist depbyment of the gabion 22 from the gabion containment apparatus 80 in this orientation.

An optional deployment method of the gabion 22 from the gabion containment apparatus 80 in this orientation is illustrated in Figs, lib and lie and occurs in a similar manner to that described above. It differs, however, in that outermost single unit gabions foflow a curved path over curved lip 106 upon application of a force in a direction indicated by arrow H. Depbyment continues from the state iflustrated in Fig. 11 b to that iflustrated in Fig. I Ic under continued application of the force in the direction indicated by arrow H. It may be the case that appcation of the force in the direction indicated by arrow H causes the gabion containment apparatus 82 to tip in the direction indicated by arrow L (see Fig. iIc. In this case, then deployment may continue in the manner illustrated in Fig. 9c and described above in relation to that figure.

In an optional arrangement, the gabion containment apparatus may be stored and/or transported in the configuration illustrated in Fig. ha, i.e. with the second plate 86 in a lowermost position. However, deployment of the gabion from the gabion containment apparatus may be via the deployment steps illustrated in Figs. 9a to 9c, and as described above, i.e. with the first plate in a lowermost position.

Turning now to Figs. 12 to 16, various possible types of releasable attaching, connecting or retentive engaging means 92, 94, 96, 98 are shown.

In Fig. 12, the releasable attaching, connecting or retentive engaging means 92, 94, 96, 98 comprises a metal ring 108 having a notch 110 therein. The notch is configured such that it causes the ring 108 to break when a predetermined hoopstress therein is attained.

In Fig. 13, a metal ring 108 is shown having a discontinuity 112 therein. Upon application of a force, the ring 108 deforms and the discontinuity 112 enlarges (as indicated by the dotted line) causing the gabion to be released from the retaining strap 88.

In Fig. 14. the end wall 12 of the gablon 22 has a loop 114 formed Integrally therewith through which the retaining strap 88 or the like can be threaded.

The loop 114 has a point of weakness 116 thereIn (in this case a notch) such that the loop 114 breaks under a predetermined load. The loop 114 could be formed integrally with any part of the gabion 22, such as a side wail 16, 18 or a hinge 14, 20. It is envisaged that such a feature would be provided on a portion of each single unit gabion of multi-compartment gabion 22.

Fig. 15 shows a releasable attaching, connecting or retentive engaging means 92, 94. 96, 98 in the form of a camming member. An aperture 118 Is provided in the body 120 thereof through which the retaining strap 88 can be threaded. Optionally, the means 92, 94, 96, 98 of this arrangement can be fixedly located at spaced intervals on the retaining strap 88.

A cam member 122 Is provided that is pivotally mounted within the body 120 about a pivot 124. One side of the cam member 122 has a cut-out 126 for receiving a part 128 of a gablon 22. The part 128 of the gabion 22 is retained by the corresponding cam member cut-out 126 and a cut-out 130 in the body 120. The cam member 122 is held in-situ by a sprung ball-bearing 132.

When an excessive load I is applied to the gabion 22, the cam member 122 rotates J and the sprung ball-bearing 132 is depressed K. The cam member 122 eventually over-centres, and the cam member cut-out 126 no longer coincides with the body cut-out 130 thereby releasing the part 128 of the gabion 22. The force I required to cause disconnection of the gabion from the releasable attaching, connecting or retentive engaging means 92 94, 96, 98 can be configured by adjusting the compressive force applied by the sprung ball-bearing 132 to the cam member 122.

Fig. 1 6 illustrates an optional arrangement where a releasable attaching, connecting or retentive engaging means 92, 94, 96, 98 is integral with the retaining strap 88.

The retaining strap 88 is formed with a plurality of hoops 140 through which parts 138 of gabion 22 pass. The hoops 140 have a frangible portion 142 therein which is configured such that it causes the hoop 142 to break when a predetermined hoop-stress is attained.

Optionally, the frangible portion 142 may comprise a notch and/or a discontinuity and/cr a perforation in the material of retaining strap 88.

Further optionally, the frangible portion 142 need not be coincident with the hoops 140, but rather may be formed in portions of the retaining strap 88 between hoops 140.

In further optional arrangements, the means for releasably attaching, connecting or retentively engaging the retaining strap 88 to a part, or parts, of gablon 22 may comprise any other suitable type of clip. For example, a karabiner-type clIp or a sprung-cam type dip may be used.

In yet further optional arrangements, the means for releasably attaching, connecting or retentively engaging the retaining strap 88 to a part, or parts, of gabion 22 may comprise any combination of one or more of the above-described releasably attaching, connecting or retentive engaging means.
