TECHNICAL FIELD

The present invention relates to a flood barrier system that is scalable in size, shape, and orientation to a wide variety of applications. The invention may be used to protect an area or building during floods. In other forms, the barrier system may also be used for containing water or other flowable solids (such as grains) in an enclosed area.

BACKGROUND

Any references to methods, apparatus or documents of the prior art are not to be taken as constituting any evidence or admission that they formed, or form part of the common general knowledge.

Increased damage from unpredictable weather events that lead to flooding has heightened the need for temporary flood control barriers which may be easily transported, quickly erected at the desired site and then disassembled when the need for flood protection is relieved. Residential and business areas with buildings of relatively high commercial value can be adversely affected by flooding. Civic authorities in flood prone regions have tried to address the issue by building levees and erecting dykes. However, such construction is expensive and not always effective in preventing flood damage.

The time available to provide at least temporary flood protection for structural developments in flood prone areas may range from hours to several days. For example, during the severe flooding of Brisbane, Australia in January 201 1 , the predicted flood levels or "crests", particularly downstream of the source of flooding, were available several days prior to the critical flood period. In this case, attempts to protect many structures in flood prone areas were unsuccessful in that sand bag barriers or temporary earthen dykes or levees were quickly breached once the flood waters impinged on these structures. However, even if permanent earthen levees or dykes were present, these structures would have been topped by the rising flood waters and efforts to increase the height of these levees using wooden planks, sandbags, or temporary sand or earth fill would have been largely unsuccessful.

The erection of sandbag and earth-fill barriers are labour and equipment intensive and time consuming and such structures can rapidly become saturated and structurally weakened to the point of failure. Still further, they create a problem with respect to removal after the flood-waters have subsided.

Currently available temporary (demountable) barriers usually comprise rigid barriers or semi-rigid connecting or interlocking components which are bulky to store, or finable tubular bladders.

The erection of temporary barriers for containing toxic liquids or flowable solids such a grains for temporary storage is also highly desirable. In view of the above, it is desirable to provide a barrier system that addresses some of the shortcomings of the prior art.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Referring to Figures 1 to 3, a barrier system 100 for flood control in a confined area is illustrated. The barrier system 100 comprises of two main parts that can be optionally assembled together when a flooding event is imminent. At least one of these parts may be uncoupled and stowed away during other periods. The following passages will provide a detailed explanation of how the barrier system 100 can readily assembled during flood events and easily uncoupled and stowed away during other periods.

In a first preferred embodiment, the barrier system 100 includes a rigid and elongate base member 1 10 (of indefinite length) that may be positioned around a perimeter of a house or a building that requires to be protected from flooding (as shown in Figure 14). The base member 110 is structured to be anchored to an underlying supporting surface. In the preferred embodiment, the inventor has envisioned that the base member 110 may be positioned in a shallow trench dug around the perimeter of the house or dwelling and be anchored and positioned within the trench such that a substantial part of the base member 1 10 is hidden from plain view. Such a configuration of the base member 110 may be considered to be structurally similar to a trench drain assembly. The inventor believes that concealing the base member 110 thereby alleviating the need to remove the base member 1 10 when the barrier system 100 is not being used.

Unlike many other barrier systems of the prior art that use heavy and bulky structures that are difficult to install and remove, the base member 110 of the present embodiment only needs to be installed once by way of anchoring the base 110 within a trench dug around the perimeter of the house or building being protected. Once anchored, the base member 1 10 can be left in a permanently installed position without the need to be removed. Referring to Figure 2B and 2C, a sectional view of the base member 1 10 has been shown in an in-use configuration wherein the base member 110 has been installed below ground level. In other optional embodiments, the base member 110 may be modified to allow the modified base member to be anchored onto the supporting surface without being positioned in a trench. Preferably, the base member 110 is entrenched such that the top surface of the base member 110 is substantially flush with the ground. As a result, the base member 110 does not present a barrier for vehicles or pedestrians to cross when not in use in the stowed position.

The base 110 is also provided with a channel 1 12 extending along the length of the elongate base 110. This channel 112 is structured to have sufficient depth that allows at least a part of a wall assembly 120 to be received into the channel 1 12 when the barrier system 100 needs to be installed in a flood preventing configuration. Such a configuration requires the wall assembly 120 to be positioned in a substantially upstanding configuration. The base 1 10 also comprises a top wall and outer side walls 114 that extend along the length of the base 1 10. Outwardly extending feet 1 13 that extend outwardly from the outer side walls 114 are also provided to support the base member 110 upon a supporting surface.

The wall assembly 120 includes a flexible barrier wall 122 having a length and a height with a connecting arrangement provided in the wall assembly 120 to allow the wall assembly 120 to be easily received into the channel 112 of the base 1 10 in order to position the flexible barrier wall 122 in a substantially upstanding position to prevent flooding of an area adjacent the barrier wall 122. The main advantage of providing a flexible barrier wall 1 12 is that the barrier wall 112 can be easily rolled away and stored easily once uncoupled from the base 1 10 as will be explained in further detail in the foregoing sections. The additional covering (such as but not limited to the cover-strip 115 shown in Figure 2) may also be positioned above the base member 110 for covering the channel 112 to prevent any contaminants from falling into the channel 1 12 when the channel 112 is not in use ie. when the barrier assembly 120 has been uncoupled from the base 1 10.

Referring to Figures 1 and 3, the wall assembly 120 includes a top frame member 124 and a bottom frame member 126 with the height of the barrier wall 122 extending therebetween such that the connecting arrangement for positioning the wall assembly 120 in the channel 1 12 is provided along the bottom frame member 126 to allow a portion of the bottom frame member 126 to be readily received into the channel 1 12 of the base member 110 during use. The connecting arrangement in the wall assembly 120 comprises a tube-shaped configuration for the bottom frame member 126 that allows the tube- shaped bottom frame member 126 to be received into and retained within a lower portion of the channel 112 when the flexible barrier wall assembly 120 has been stowed away.

Referring to Figures 2A to 2C, the channel 1 12 in the base 110 is also provided with a relatively narrower mouth portion 1 17 with a width w2 that is located directly above the relatively broader and larger bottom portion 1 19 of the channel 112 having a width w1 which is sized for receiving the tube-shaped bottom frame member 126 of the wall assembly 120. In the preferred embodiment, the bottom channel portion 1 19 defines a curved surface that is adapted to engage a corresponding curved surface of the bottom frae member 126. The unique configuration of the channel 112 allows the bottom member 126 be received into the lower portion 1 19 of the channel 1 12 to position the flexible barrier wall 122 in a substantially upstanding position and for simultaneously preventing the bottom member 126 from being passed through the opening defined by the upper portion 1 17 of the channel in an upwardly direction. Such a novel configuration of the channel 1 12 ensures that the wall assembly 1 12 is not inadvertently withdrawn out of the channel 1 12 when forces are acting in an upwardly direction. As explained earlier, the system 100 is for providing an improved flood barrier It is also important to note that, during use, as the water level adjacent the flexible barrier wall 122 starts rising, the hydrostatic pressure increases which may exert pulling forces on the bottom frame member 126 in an upward direction towards the upper portion/roof the of the channel 112. This pulling force also results in the curved surface of the bottom member 126 being pushed against the curved walls of the lower channel portion 1 19 resulting in a self-sealing effect. The reduced width w2 of the upper channel portion 1 17 ensures that that the bottom member 126 of the frame assembly is retained in the channel 1 12. In this regard, the bottom member 126 may be formed from a resilient or flexible material to be sufficiently rigid to form a seal with the walls of the channel 1 12 whilst being sufficiently flexible to allow the bottom frame member 126 to flex during use.

The unique narrow mouth configuration of the channel 1 12 also allows the cover 1 15 to be plugged into and fastened with the walls defining the opening of the narrower channel portion 1 17 when the wall assembly 120 is not being used.

One of the possible ways of coupling the wall assembly 120 from the base member 1 10 is to impart relative axial movement between the wall assembly 120 and the base member 1 10 (shown by the arrow in Figure 3) and withdraw the wall assembly 120 from one of the two ends of the base 110. By way of example, if we refer to Figures 2A and 3, the bottom frame member 126 is inserted into the channel 1 12 by sliding the bottom frame member 126 in axial direction of the channel 1 12 via a guide opening 11 1 which has a slightly broader opening to allow easy insertion of the bottom member 126 into the channel 1 12. The guide opening 1 1 1 may be provided on one of the ends of the base member 1 10 (as shown in Figures 1 to 3) or in alternative embodiments two guide openings 1 11 may be provided at either end of the base member 1 10.

Referring to Figures 1 and 3, the top frame member 124 comprises a loop extending along the length of the top portion of the barrier wall 122. A flexible line 121 (such as a metallic cable with sufficient tensile strength) passes through the loop to provide the top frame member 124. The insertion of the line 121 into the loop of the top portion of the wall assembly 120 forms the top frame member 124 and provides structural support along the length of the top portion of the wall assembly 120. During use, the tension in the line 121 may be varied by using a tension adjuster 123 to easily adjust tension in the line 121 in order to maintain the upper portion of the the barrier wall 122 in an upright position during use. In at least some embodiments, the tension adjuster 123 may be useful for inter- connecting separate tensioning lines 121. By way of example, if the two ends of the barrier assembly 120 are connected to respective additional barrier members 120 or any other structures that may or may not form part of the presently described barrier system 100 then such a tension adjuster may include additional coupling arrangements for forming such inter-connections. The upper and lower members 124 and 126 may be permanently attached to the flexible barrier wall 122 and may be rolled up with the upper and lower members 124 and 126 when not in use. The flexible line 121 may also be rolled up along- with the wall assembly and may not be withdrawn out of the loop of the top frame member 124.

The wall assembly 120 also includes spaced apart lateral frame members 125 at either lateral end of the of the wall assembly 120 (as shown in Figure 1). As discussed in the earlier sections, the wall assembly 120 is adapted to allow the barrier wall 122 to be easily rolled length-wise in between the lateral frame members 125 such that once the lower frame member 126 is withdrawn out of the channel 1 12 for the base 1 10, the barrier wall can be easily rolled and put away in storage.

Figures 4 to 6 illustrate a second embodiment of a barrier system 200 that uses a base member 210 which has an alternative structural configuration when compared with the base member 110 from the previously described barrier system 100. The main difference between the base member 210 when compared with base member 110 is that base member 210 does not include outer walls that depend downwardly from a top portion of the base member 210. Instead, the base member 210 includes outwardly extending lateral wall portions with ends that that sit flush on ground level when installed into a trench and suspend the channel 212 into the trench. As shown in Figure 6, pegs or other types of fasteners may be used for fastening the base member 210 onto the ground during installation of the base 210. The base member 210 includes a channel 212 which has structural configuration that is similar to channel 112 as has been previously described. Specifically, the channel 212 includes a narrower top portion 217 and a broader bottom channel portion 219 that has a curved surface that can abut a corresponding curved surface of a bottom member 226 of the wall assembly 220. The wall assembly 220 also includes a top frame member 224 and a bottom frame member 226 with the height of the barrier wall 222 extending there- between such that the connecting arrangement for positioning the wall assembly 220 in the channel 212 is provided along the bottom frame member 226 to allow a portion of the bottom frame member 226 to be readily received into the channel 212 of the base member 210 during use. The connecting arrangement in the wall assembly 220 also comprises a tube-shaped configuration for the bottom frame member 226 that allows the tube-shaped bottom frame member 226 to be received into and retained within a lower portion of the channel 212 when the flexible barrier wall assembly 220 has been erected in an upstanding position.

During use, the upstanding wall assembly 220 is further supported by one or more supporting assemblies 230. Each barrier support assembly 230 comprises a triangular supporting wall 232 extending transversely relative to the barrier wall 222. The supporting wall 232 comprises a relatively narrower top part that forms the apex of the triangular wall 232 and is coupled to the top member 224 of the wall frame assembly 220. The supporting wall 232 also includes a relatively broader bottom part coupled to a base 234 of the support which is adapted to be positioned on the ground. A number of such supports may be positioned one side or both sides of the barrier wall assembly 220 to provide additional support to the wall assembly during use. The support 230 may either be integrally formed with the flexible barrier wall 222 or in other embodiments the supports 230 may be provided in the form of discrete supporting members that are positioned adjacent to the wall assembly 120 (once erected) to provide additional support if required.

Referring to Figures 4 to 6, the barrier system 200 also comprises a joining member 240 that can be used to join two separate wall assemblies 220 along their lateral frame members 225. The joining member 240 is also adapted to be coupled to two adjacently located base members 210. The joining member 240 is provided to form a continuous inter-connected barrier system that can be easily used to interconnect wall assemblies at various angles. For example, in Figure 5, the joining member 240 is structured or shaped to inter-connect two wall assemblies at right angles to one another. Each joiner member 240 includes two upright channels 242 located at either lateral end of the joiner member 240. Each of the upright channels 242 is configured to receive a lateral frame member 225 from a respective wall assembly 220 thereby allowing two wall assemblies of the barrier system 200 to form a continuous flood barrier along a length of the perimeter of the area being protected from floods. Similarly Figure 4 shows the joiner member 240 being shaped to include two channels 242 that allow two wall assemblies 220 to be positioned in a co-planar manner. In some embodiments, the joiner member 240 may have a base that could be coupled to the base member 210. In alternative embodiments, the joiner member 240 may be adapted to be positioned on and coupled to the ground without being directly coupled to the base member 210.

The wall assembly 220 also includes spaced apart lateral frame members 225 at either lateral end of the of the wall assembly 220 (as shown in Figure 4). As discussed in the earlier sections, the wall assembly 220 is adapted to allow the barrier wall 222 to be easily rolled length-wise in between the lateral frame members 225 such that once the lower frame member 226 is withdrawn out of the channel 212 for the base 210, the barrier wall can be easily rolled and put away in storage.

Referring to Figures 7 and 7A, an additional support member 330 is shown for use with the barrier system 200. Once again, the support 330 provides additional support to the erect barrier wall assembly 220 and prevent the wall assembly 220 from collapsing during periods when water is applying pressure against the barrier wall 222 during a flood event. Each additional support 330 includes an upper portion 332 that can be coupled to a top frame member 224 of the wall assembly 220 and an extendable leg portion 334. In this instance, the additional support 330 may be directly coupled to the tensioning line 221 passing through the loop formed in the top frame member 224. The plurality of the additional support members 330 may be positioned transversely relative to the wall assembly 220 such that respective top portions 332 of the support members 330 can be easily connected to the top frame 224 at a plurality of spaced locations along the top frame 224. In the preferred embodiments, the leg 334 is telescopic and allows the length of the leg to be adjusted so that the supports 330 can be positioned on undulating surface.

Referring to Figures 8, 8A and 8B, another embodiment of the additional support 430 has been illustrated for use with system 200. Like reference numerals denote like features that have been previously disclosed. Each of the additional supports 430 includes a pair of supporting members that are joined together at an upper portion 432 with telescopic legs 434A and 434 depending in mutually opposed downwardly direction. Once again, upper portion 432 of each additional support 430 may be coupled with the tensioning line 221 located in the loop that forms a part of the top frame 224 of the wall assembly 220 as shown in Figure 8. In the preferred embodiments, the legs 434 are telescopic which allows the length of each leg to be adjusted so that the supports 430 can be positioned on an uneven surface.

It is important to note that each of the top portions of the respective support members 330 or 430 may be passed through a cut-out opening 229 provided in the loop of the top frame member 224. As a result, the supporting assembly 330 or 430 supports the flexible barrier wall 222 to maintain the barrier assembly 220 in a substantially upstanding position. A retaining arrangement may be provided on the respective upper portions 332 or 432 to secure the tensioning line 121 to the upper portion 332 or 432 of the supports 330 or 430.

Referring to Figures 9 to 14, the system 200 may further include a bollard assembly 500. Referring to Figure 10, the bollard assembly 500 comprises a bollard housing 530 housing with a roller mechanism positioned in the housing. The roller mechanism comprises a drum 532 around which the flexible wall assembly 220 can be wound to allow the flexible wall assembly to be stowed during periods of non-use whilst the bollard is positioned upon the base member 210. The bollard assembly 500 is configured to receive and store the wall assembly 220 in a stowed configuration whilst being fastened either to the base member 210 or to an underlying surface by a fastening arrangement 520 the bollard assembly comprising a fastening arrangement to allow the bollard assembly to be fastened to the base member 210 and be positioned in a substantially upright position. The roller may be mechanically driven by a hand held roller handle 510. In alternative embodiments, the roller may also be driven using a motor.

The bollard housing 530 also comprises a channel 542 that runs along the height of the bollard housing 530. The placement of the channel 542 allows the channel 542 to receive a lateral frame 225 and allow the deployment of a wall assembly 220 into a substantially upstanding position. In this manner, the bollard assembly 500 functions not only as a storage device for stowing the rolled wall assembly but also as a joiner member to join adjacently positioned wall assemblies 220. Figures 1 1 and 12 provide two alternative embodiments for fastening the bollard housing 500 onto the base member (denoted by 210). Like reference numerals denote like features that have been previously described. The first fastening arrangement 210A shown in Figure 11 comprises a bayonet lock connecting arrangement that allows the bayonet pins 533 on the bollard housing 530 to be locked into a circular channel 534 of a socket 535. The bayonet design is not intended to be a single geometry element that unto itself is design critical to the operation concept of this mechanism. Alternate methodology may be used to facilitate securement of the bollard housing 530 to the base member 210. The second alternative type of fastening arrangement 520 B (as shown in Figure 12) comprises a base plate 536 with a spigot 537. The base plate 536 may be positioned flush with the ground level and/or one or more base members 210 with the spigot portion 537 being driven into the ground. A lower portion of the bollard housing 530 may be fastened to the base plate 536 by way of fasteners such as screws or bolts.

Turning to Figure 14, a perspective in-use view of the barrier system 200 has been shown. The barrier 200 has been constructed by inter-connecting several wall assemblies 220 with each other by using four bollard members 500. A typical installation process would involve unfurling the flexible barrier wall 222 in a lengthwise direction and positioning the lower frame member 226 for each wall assembly 120 into the channel 212 of the base members 210 anchored along the perimeter of the house. At each of the four corners of the area to be protected, the bollard assemblies 500 are positioned to inter-connect the wall assemblies 220 in a continuous manner. Support assemblies 230 and 330 have also been shown in use. The support assemblies extend transversely from the barrier wall assemblies 220 in a manner as previously described to provide additional support to the erected wall assembly 220 during periods of flooding. It will be understood that the system 200 is in no way limited to using a plurality of barrier assemblies 220. For example, a single continuous barrier assembly 220 may be coupled with one or a plurality of base members 1 10 for forming a continuous barrier wall without departing from the spirit and scope of the invention.

The presently described embodiments of the barrier systems 100 or 200 refers to use during floods. However, such use is not limiting and the barrier system 10Oin accordance with other embodiments may be utilised for containment of toxic chemical either in liquid or solid form or other materials such as grains within a confined space. The use of the barrier systems 100 and 200 is not limited to being used to confine a given area. By way of example. The systems 100 or 200 may be positioned across a door opening in a building to prevent water from entering the house during a flooding event.
