Definitions
- the present invention relates to a flood defence assembly, and relates particularly, but not exclusively, to an assembly adapted to be disposed adjacent a body of water that is susceptible to flooding.
- a flood defence assembly may comprise support posts which can be fixed into the ground and panels which are fitted between the support posts to form the flood defence barrier.
- Prior art flood defence assemblies of this type suffer from the drawback that expensive infrastructure must be laid adjacent to the body of the water that is susceptible to flooding.
- metal anchor plates must be permanently cast into a concrete ground beam, the anchor plates being adapted to support the metal supporting posts.
- a plurality of dam beams are then fitted between the posts and compressed with a pressing tool.
- Another problem with this system is that very close tolerances are involved, and the system therefore only works on flat horizontal surfaces hence the need for a ground beam foundation.
- Preferred embodiments of the present invention seek to overcome the disadvantages of the prior art.
- a flood defence assembly comprising:—
- a plurality of panel members adapted to be disposed between adjacent pairs of support members to form a barrier for substantially preventing ingress of water
- said support members are adapted to hold the panel members at an acute angle relative to the horizontal such that the weight of water acting on at least one said panel member aids the formation of a seal between said panel member, at least one corresponding said support member and a surface on which said assembly is placed.
- this provides the advantage that the weight of the flood water is utilised to push the panels into the support and the ground in order to form a seal and prevent the ingress of water past the flood defence assembly.
- the design tolerances of the flood defence assembly can be less than that of prior art flood defence assemblies, such that the costs of both manufacturing and operating the flood defence assembly are reduced. This also provides the advantage that the flood defence assembly can follow contours and inclines.
- At least one said panel member is flexible.
- This provides the advantage of further increasing the effectiveness of forming a seal, because the panel members tend to flex in order to take up a sealing position.
- this provides the advantage that the flood defence assembly can be used on uneven ground as the flexible panels take up the shape of the uneven ground.
- This also provides the advantage that the panels can be thinner than those of the prior art.
- At least one said panel member is formed from plywood.
- Said acute angle may be between 15° and 30°.
- the assembly further comprises a plurality of seal members adapted to be disposed between at least one said support member and at least one said panel member and the surface on which the assembly is placed, and/or between at least one said support member and the surface on which the assembly is placed.

- At least one said seal member may be formed from closed cell rubber.
- the assembly further comprises a plurality of restraint members adapted to be mounted to at least one said support member and/or at least one said panel member in order to reinforce said panel member.
- This provides the advantage of further increasing the strength of the panel members, in particular to limit the extent to which the panel members can flex and also to assist the panel members in absorbing impacts from the wave motion of water or impacts from water borne objects.
- At least one support member may comprise a sleeve member adapted to be removably disposed over a bollard disposed adjacent a body of water, the sleeve member having at least one recess adapted to slidably engage a panel member.
- the sleeve member By providing a sleeve member that can be removably disposed over a bollard, the sleeve member having at least one recess adapted to slidably engage a panel member, this provides the advantage that a supporting bollard can be left in place adjacent the body of water that is susceptible to flooding, and when there is risk of a flood, the support members can simply be dropped over the bollards to provide easy mounting and removal of the support members. Also, as the sleeve members have at least one recess adapted to slidably engage the panel members, this provides the advantage that the panel members can be easily slid into place, and no dedicated tools are required to either erect the sleeve members or join the panel members to the sleeve members.
- the assembly may further comprise at least one bollard disposed adjacent a body of water in use.
- Said sleeve member may comprise a plurality of rings.

Abstract
A flood defence assembly comprises a support member (2) formed from steel or other rigid material and having a sleeve portion (4) that is adapted to be slidably mounted on a bollard (6). Bollard (6) is set into the ground (8) to an appropriate depth adjacent a body of water that is susceptible to flooding. The support member (2) comprises first and second support panels, which form a slot (14) into which a panel member (16) is slidably mountable. Support member (2) is also provided with a plurality of brackets (19) for supporting restraint members (20) in the form of metal tubes or other members of similar strength. Buttress members (22) are disposed between the sleeve portion (4) and the back panel of support members (2). A rubber sheet (24) can be removably placed along the ground (8) at the point where the panel member (16) contacts the ground (8). When a body of floodwater (26) rises, the weight of the floodwater (26) deforms panel member (16) and pushes the panel member (16) downwardly onto rubber sheet (24) and into the rubber seal members (not shown) disposed in slot (14). The restraint member's (20) support the panel members (16) at the maximum deflection of panel member's (16).
Description
- The present invention relates to a flood defence assembly, and relates particularly, but not exclusively, to an assembly adapted to be disposed adjacent a body of water that is susceptible to flooding.
- Permanent, temporary or demountable flood defence assemblies are required to protect property that is susceptible to flooding. A flood defence assembly may comprise support posts which can be fixed into the ground and panels which are fitted between the support posts to form the flood defence barrier.
- Prior art flood defence assemblies of this type suffer from the drawback that expensive infrastructure must be laid adjacent to the body of the water that is susceptible to flooding. For example, in one system metal anchor plates must be permanently cast into a concrete ground beam, the anchor plates being adapted to support the metal supporting posts. When the supporting posts are bolted to the anchor plates, a plurality of dam beams are then fitted between the posts and compressed with a pressing tool. Another problem with this system is that very close tolerances are involved, and the system therefore only works on flat horizontal surfaces hence the need for a ground beam foundation.
- Preferred embodiments of the present invention seek to overcome the disadvantages of the prior art.
- According to the present invention, there is provided a flood defence assembly comprising:—
- a plurality of support members adapted to be placed adjacent a body of water; and
- a plurality of panel members adapted to be disposed between adjacent pairs of support members to form a barrier for substantially preventing ingress of water;
- wherein said support members are adapted to hold the panel members at an acute angle relative to the horizontal such that the weight of water acting on at least one said panel member aids the formation of a seal between said panel member, at least one corresponding said support member and a surface on which said assembly is placed.
- By providing a plurality of support members adapted to hold a plurality of panel members at an acute angle relative to the horizontal such that the weight of water held by the panel aids the formation of a seal between the panel members, the support members and the surface on which the assembly is placed, this provides the advantage that the weight of the flood water is utilised to push the panels into the support and the ground in order to form a seal and prevent the ingress of water past the flood defence assembly. As a result of holding the panel members at an acute angle and utilising the weight of the water to help to form a seal, the design tolerances of the flood defence assembly can be less than that of prior art flood defence assemblies, such that the costs of both manufacturing and operating the flood defence assembly are reduced. This also provides the advantage that the flood defence assembly can follow contours and inclines.
- In a preferred embodiment, at least one said panel member is flexible.
- This provides the advantage of further increasing the effectiveness of forming a seal, because the panel members tend to flex in order to take up a sealing position. In particular, this provides the advantage that the flood defence assembly can be used on uneven ground as the flexible panels take up the shape of the uneven ground. This also provides the advantage that the panels can be thinner than those of the prior art.
- At least one said panel member is formed from plywood.
- This provides the advantage that the panels can be formed from cheap and readily available material.
- Said acute angle may be between 15° and 30°.
- It has been found that an angle of between 15° and 30° formed between the panel member and the surface of the ground is the most efficient at utilising the weight of the water to form a seal.
- In a preferred embodiment, the assembly further comprises a plurality of seal members adapted to be disposed between at least one said support member and at least one said panel member and the surface on which the assembly is placed, and/or between at least one said support member and the surface on which the assembly is placed.
- This provides the advantage of further increasing the water retaining properties of the assembly.
- At least one said seal member may be formed integrally on at least one said panel member.
- At least one said seal member may be formed from closed cell rubber.
- In a preferred embodiment, the assembly further comprises a plurality of restraint members adapted to be mounted to at least one said support member and/or at least one said panel member in order to reinforce said panel member.
- This provides the advantage of further increasing the strength of the panel members, in particular to limit the extent to which the panel members can flex and also to assist the panel members in absorbing impacts from the wave motion of water or impacts from water borne objects.
- At least one support member may comprise a sleeve member adapted to be removably disposed over a bollard disposed adjacent a body of water, the sleeve member having at least one recess adapted to slidably engage a panel member.
- By providing a sleeve member that can be removably disposed over a bollard, the sleeve member having at least one recess adapted to slidably engage a panel member, this provides the advantage that a supporting bollard can be left in place adjacent the body of water that is susceptible to flooding, and when there is risk of a flood, the support members can simply be dropped over the bollards to provide easy mounting and removal of the support members. Also, as the sleeve members have at least one recess adapted to slidably engage the panel members, this provides the advantage that the panel members can be easily slid into place, and no dedicated tools are required to either erect the sleeve members or join the panel members to the sleeve members.
- The assembly may further comprise at least one bollard disposed adjacent a body of water in use.
- Said sleeve member may comprise a plurality of rings.
- This provides the advantage of reducing the weight and cost of the support members.
- At least one said support member may further include at least one flange adapted to prevent removal of said panel member in a forward direction from the support member.
- The assembly may further comprise at least one wedge member adapted to be inserted between said panel member and at least one flange to wedge the panel member against said support member.
- This provides the advantage of increasing the strength of the seal between the panel and the support member.
- At least one said support member may further include a plurality of pins adapted to prevent removal of said panel member in a forward direction from the support member.
- The assembly may further comprise at least one wedge member adapted to be inserted between said panel member and at least one pin to wedge the panel member against said support member.
- This provides the advantage of increasing the strength of the seal between the panel and the support member.
- The assembly may further comprise at least one fixing bracket adapted to be mounted on at least one said pin, said fixing bracket comprising biasing means adapted to bias at least one said panel member against the corresponding recess.
- This provides the advantage of increasing the strength of the seal between the panel and the recess in which the panel is held.
- Said biasing means may comprise at least one bolt mounted in at least one corresponding threaded hole formed in said fixing bracket.
- At least one support member may comprise a concrete block adapted to be placed adjacent a body of water and having at least one recess adapted to slidably engage a panel member.
- This provides the advantage that the flood defence assembly can be completely removed from adjacent the body of water when there is no risk of a flood. Due to the weight of the concrete blocks, no other infrastructure such as bollards are required in order to support to the concrete blocks.
- The assembly may further comprise:
- at least one barrier member adapted to be connected to at least one support member to form an enclosure adjacent to at least one said panel member; and
- granular material for filling said enclosure to form a seal between the barrier member and said panel member.
- This provides the advantage of providing a seal along the ground in front of the panel member, which is particularly useful when the panels are disposed on uneven ground.

FIG. 13 is a cross sectional view of the third embodiment of the flood defence assembly of the present invention comprising a ground seal assembly. - Referring to
FIGS. 1 to 6 , a first embodiment of a flood defence assembly comprises asupport member 2 formed from steel or other rigid material and having asleeve portion 4 that is adapted to be slidably mounted on abollard 6.Bollard 6 is set into theground 8 at an appropriate depth, such as one metre, adjacent a body of water that is susceptible to flooding. Thesupport member 2 comprises first andsecond support panels slot 14 into which apanel member 16, formed from plywood or a material with similar properties, is slidably mountable. -
Support member 2 is also provided with aback panel 18 to which a plurality ofrestraint members 20 in the form of metal tubes or other members with similar strength can be mounted tobrackets 19. A pair of buttressmembers 22 is disposed between thesleeve portion 4 and theback panel 18 to provide support to the assembly. Arubber sheet 24 or sheet of material with similar properties can be removably placed along theground 8 at the point where thepanel member 16 contacts theground 8.Rubber sheet 24 may have grooves (not shown) formed on its underside to increase the force of contact with the ground whensheet 24 is put under pressure (i.e. by the weight of water and panel member 16), to increase the strength of the seal formed byrubber sheet 24. - Referring to
FIGS. 2 b and 4 b,seal members 40 formed from a closed cell rubber material or material with similar properties can be placed between thepanel members 16 andsecond support panels 12 to provide a seal against ingress of water. Wedge members (not shown) can be placed between thefirst support panels 10 and thepanel members 16 to push thepanel members 16 against theseal members 40. - Referring to
FIGS. 5 and 6 , in order to erect the flood defence assembly a plurality ofsupport members 2 are mounted onbollards 6 which are permanently in place alongside a body of water that is susceptible to flooding. Thesupport members 2 are designed to be light enough to be carried by a maximum of two persons, such that they can be dropped overbollard 6 without the need for any machinery. Thepanel members 16 can then be slid intoslots 14 again by a maximum of two persons without the need for lifting machinery. It should be noted that neither thesupport members 2 nor thepanels 16 require any fixings such as nuts and bolts to mount them in place.Restraint members 20 can then be mounted tobrackets 19 formed onsupport members 2 in order to reinforce thepanel members 16.Rubber sheeting 24 can also be placed underneath thepanel members 16. A plurality of further rubber seals (not shown) are placed at the interface between the edges of thepanel members 16 and theslot 14. - When a body of
floodwater 26 rises, the weight of thefloodwater 26deforms panel member 16 and pushes thepanel member 16 downwardly ontorubber sheet 24 and into the rubber seal members (not shown) disposed inslot 14. Therestraint members 20 support thepanel members 16 at the maximum deflection ofpanel members 16. It can therefore be seen that the weight of thefloodwater 26 pushes thepanel members 16 into their respective seals, andrestraint members 20 prevent the panel from flexing too far. Due to the deformable nature of thepanel members 16, and the use of the weight of theflood water 26 pushing thepanel members 16 against the rubber seals, this flood defence assembly can be used on uneven ground, and can also be manufactured at relatively low expense because there is no need for close tolerances to form tight seals against the ingress offlood water 26. - It has been found that the system works best at an acute angle α (
FIG. 1 ) between the ground and the panel members of between 15° and 30°, although any acute angle could be used. - Referring to
FIGS. 7 a and 7 b, the second embodiment of the flood defence assembly comprises a planter 29 in which plants and trees can be planted, aconcrete block 28 or other item of street furniture such as a waste disposal holder.Concrete block 28 and planter 29 have pairs of laterally opposedangular slots 30 which are adapted to slidably receivepanel members 32.Concrete block 28 or planter 29 do not require bollards to hold them in place due to their weight, and can be mounted in a line on arubber sheet 34 adjacent a body of water that is susceptible to flooding. -
Restraint members 36 are mountable onbrackets 38 behind thepanel members 32, and rubber seals 40 can also be placed in theslots 30 between the points where thepanel members 32 contact theslots 30. - Referring to
FIG. 8 ,floodwater 42 deforms thepanel members 32 and pushes thepanel members 32 intorubber seals restraint members 36 support the back of thepanel members 32, such that a seal is formed. The weight of the concrete blocks 28 is selected so that the weight of thefloodwater 42 cannot move the concrete blocks 28. All of the components of this embodiment of the invention are designed such that they can be carried by two persons, except the concrete blocks 28 or planters 29 which require lifting equipment. - A third embodiment of flood defence assembly is shown in
FIGS. 10 to 11 b, with parts common to the embodiment ofFIGS. 1 to 6 denoted by like reference numerals but increased by 100. - A
support member 102 comprises supportingrings 150 connected to abacking member 118 by buttressmembers 122. Therings 150 can be placed over bollards (not shown) disposed in the ground. Backingmember 118 comprises a plurality ofrestraint member apertures 152 through whichrestraint members 120 can be slidably mounted.
