Definitions

  • the present invention concerns a barrier comprising a plurality of individual barrier units in a linear arrangement and a relatively rigid energy transfer means.
  • the barrier may be used to resist vehicle ramming attack.
  • Barriers intended to deal with vehicle collisions are well known in the art. In some applications, such as in military applications, barriers are required to prevent the vehicle from breaking through the barrier i.e. to be resistant to vehicle ramming attack. Otherwise, the vehicle itself or other subsequent vehicles can launch further attacks once the barrier has been breached. Standard testing for such barriers is well known in the art, for example by measuring the resistance of the barrier to an impact of a 15,000 lb truck travelling at 22.35 m/s.
  • Barriers currently used for this purpose include rows of concrete blocks, with each block connected to the blocks adjacent to it.
  • the concrete is sufficiently heavy that it is resistant to vehicle ramming attack.
  • Such barriers require water in order to make the concrete, which is not always available.
  • WO90/12160 discloses a gabion barrier that can be filled with concrete, wherein a concrete reinforcing rod can pass through the gabion baskets.
  • GB2512336 discloses a gabion barrier comprising a row of gabions and a row of posts and panels supported by the gabions. The posts may be supported by concrete blocks engaged with the fill material.
  • WO01/11146 discloses a barrier system comprising abutting barrier elements and a longitudinally extending guard mounted thereon.
  • GB2440145 discloses a barrier formed from vehicle tyres arranged to form a tube that are secured together using straps, wires or cord, or by a support frame or a wrap of material such as plastic sheeting or a mesh sleeve.
  • JP2004230697 discloses a row of logs arranged in parallel and surrounded with steel band members which are attached to each of the logs.
  • EP0202552 discloses a space element that can be used to reinforce slopes comprising latticework baskets that may be spaced apart by a rod.
  • a barrier comprising a plurality of individual barrier units in a linear arrangement and a relatively rigid energy transfer means, wherein the energy transfer means comprises at least one continuous member extending along the length of the plurality of individual barrier units that is connected to each individual barrier unit in the plurality, such that when a force is applied to one individual barrier unit in the plurality, the energy transfer means transfers part of the energy associated with the applied force to other individual barrier units in the plurality of individual barrier units.
  • the force applied to one individual barrier unit in the plurality may be the result of a collision between an object and the barrier unit, wherein the object may be a vehicle.
  • the barrier units may be placed on a surface and the force applied to the individual barrier unit may be perpendicular to the length of the plurality of individual compartments and parallel to said surface.
  • FIG. 1 illustrates a first embodiment of a barrier according to the present invention
  • FIG. 2 illustrates an enlarged view of the energy transfer means of the barrier of FIG. 1 ;
  • FIG. 3 illustrates the way in which the energy transfer means of the barrier of FIG. 1 is connected to the individual barrier units;
  • FIG. 4 illustrates a friction increasing means according to the present invention
  • FIG. 5 illustrates a second embodiment of a barrier according to the present invention
  • FIG. 6 illustrates an alternative embodiment of an energy transfer means that can be used in the present invention.
  • FIG. 7 illustrates an alternative embodiment of an energy transfer means that can be used in the present invention.
  • the energy transfer means in the present invention enhances the connection between the individual barrier units, thereby increasing the effective mass of the system without requiring an increase in mass of the individual barrier units.
  • by connecting the barrier units with the energy transfer means it is no longer only the mass of the barrier unit involved in the collision that is relevant but the mass of all of the barrier units in the plurality connected by the energy transfer means.
  • the arrangement of the present invention means that if a force is applied to an individual barrier unit, such as a vehicle colliding with the barrier unit, the energy transfer means is engaged and acts to pull the other barrier units in the plurality in the direction of the force.
  • the energy transfer means therefore connects the plurality of barrier units such that in combination, the plurality of barrier units and the energy transfer means act as a single energy transfer system. This acts to dissipate the energy involved in the collision, thereby increasing the barrier's resistance to ramming attack.
  • the energy transfer means transfers a majority of the energy associated with the applied force (i.e. over 50% of the energy). Even more preferably, the energy transfer means transfers almost all of the energy associated with the applied force (i.e. over 80% or over 90% of the energy).
  • the use of numerous barrier units to form the barrier means that the barrier can be deployed quickly and easily.
  • the length of the barrier is variable, depending on the number of barrier units.
  • the plurality of barrier units in the barrier can be of any number and thus the barrier can be of indefinite length.
  • the linear arrangement of the barrier units does not have to be a straight linear arrangement. Instead, the units may be positioned to allow the linear barrier to curve or change direction, so as to avoid any obstacles that may be present as the barrier is deployed.
  • the plurality includes three or more barrier units.
  • the barrier units are the units that create the front of the barrier, the front being one of the elongate surfaces of the linear barrier, perpendicular to the surface on which the barrier is placed (i.e. not the top or bottom of the barrier), to which a force is likely to be applied.
  • This front is preferably continuous, with no space between adjacent barrier units. It is therefore the barrier units themselves that create the obstacle, while the energy transfer means merely connects the units and preferably does not contribute to the obstacle created by the barrier.
  • relatively rigid it is meant that the energy transfer means is not readily deformed by weak forces, such as those experienced while the barrier is being deployed.
  • strong forces such as those involved in the collision of a vehicle with the barrier, may act to at least partially deform the energy transfer means.
  • This term is therefore intended to cover means such as wires, which may demonstrate some deformation on the application of strong forces, as long as they are not deformed during the deployment of the barrier.
  • the energy transfer means may comprise a bar, a rod, a wire, a hollow tubing or another elongate member which can extend along the plurality of the individual barrier units, such as that used in motorway crash barriers seen in central reservations (Armco Barriers).
  • a bar is used as it experiences less stretching when a force is applied compared to other arrangements, such as wire.
  • the energy transfer means may be flat, for example a flat bar.
  • the energy transfer means may be made out of a metal, such as steel, alloys or a woven material such as a canvas netting. If steel is used, this is preferably high tensile steel. Rods made from these materials are considered sufficiently rigid to form the energy transfer means of the present invention.
  • the energy transfer means may comprise two or more elongate members, which may be connected to one another at the point at which the energy transfer member is attached to the individual barrier units.
  • elongate it is meant that the continuous means has a length sufficient to extend along the length of the barrier. Preferably, the length of the continuous means is its longest dimension.
  • the energy transfer means acts as a single member to transfer the energy associated with the applied force.
  • the energy transfer means may comprise a continuous rod (or other elongate members), or may comprise two or more rods (or other elongate members) connected together to form a continuous energy transfer means.
  • the two or more elongate members may have different lengths.
  • the connection must be sufficiently strong that the energy transfer means acts as a single member to transfer the energy associated with the applied force, so that there is no reduction of energy transfer at the connection.
  • the elongate member itself must break before the connection between adjacent elongate members does, so no energy is lost at the connection.
  • the energy transfer means being “connected to each individual barrier unit” requires a connection between the energy transfer means and each barrier unit, which retains the energy transfer means in a position relative to each individual barrier unit in the plurality.
  • the movement of the energy transfer relative to each barrier unit is therefore restricted, due to the connection between the energy transfer means and the barrier unit in question.
  • the energy transfer means cannot move relative to each barrier unit.
  • the elongate member is the same either side of the connection, i.e. two identical elongate members are attached by the connection. This helps to increase the energy transfer along the energy transfer means.
  • connection between adjacent elongate members may be any suitable connection known in the art, such as a nut or clamp arrangement.
  • the energy transfer means comprises a hollow metal tube, such as a square hollow metal tube
  • the connection may comprise an overlapping region of adjacent tubes, wherein the end of one tube fits inside the end of the adjacent tube. Holes may be present in one or more side walls of both ends, which are then aligned when the ends of the tubes overlap. Pins can then be placed into the holes to hold the tubes together.
  • connection may comprise a hole through the end of the energy transfer means.
  • the energy transfer means preferably comprises a flat surface, for example is a flat bar.
  • a corresponding hole on the adjacent energy transfer means is aligned with said hole and a locking member is then inserted through both holes.
  • the locking member can be fastened using known fastening means such as nuts and bolts.
  • the elongate member may be threaded. This can help to connect two or more elongate members together to form an energy transfer means, as well as helping to connect the energy transfer means to the individual barrier units.
  • the energy transfer means may extend along the front and/or along the back of the plurality of individual barrier units.
  • the front and back are defined as the two elongate surfaces of the linear barrier, perpendicular to the surface on which the barrier is placed (i.e. not the top or bottom of the barrier).
  • the energy transfer means may extend along one or both of the elongate surfaces of the linear barrier.
  • the front surface is intended to refer to the surface to which a force is to be applied, while the back surface is the surface opposite the front surface.
  • the energy transfer means extends along the front of the plurality of individual barrier units.
  • the barrier comprises a first energy transfer means extending along the front of the plurality of individual barrier units and a second energy transfer means extending along the back of the plurality of individual barrier units.
  • the first and second energy transfer means may be the same or different in construction.
  • the energy transfer means may be present within the barrier units or along the outer face of the barrier. Including the energy transfer means internally in the barrier units means that no surface is provided on the outside of the barrier that may help an individual climb over it.
  • the energy transfer means may be positioned at a height such that the chassis of a vehicle would not hit the energy transfer means.
  • the energy transfer means comprises at least two elongate continuous members and is positioned at a height such that the chassis of a vehicle would impact the barrier between the two elongate members of the energy transfer means, such as between two rods. This would mean that the vehicle may be lifted off the ground on collision with the barrier, thereby reducing the energy that is applied to the barrier by the collision.
  • the barrier may further comprise connecting means that connect an individual barrier unit in the plurality to at least one adjacent barrier unit.
  • the barrier may comprise a plurality of connecting means, with each connecting means connecting an individual barrier unit to one adjacent barrier unit.
  • each connecting means connecting an individual barrier unit to one adjacent barrier unit.
  • it is the connecting means that maintain the barrier units in position relative to one another and the energy transfer means that acts to transfer part of the energy associated with an applied force to other individual barrier units in the plurality of individual barrier units.
  • Such connecting means may be any known in the art, such as screws, bolts, clamps or any other industry standard component joining mechanism. This further increases the efficiency of the energy transfer from the individual barrier unit to which the force is applied to the other barrier units in the plurality. This also increases the ease with which the barrier may be deployed.
  • the barrier may be surface mounted, i.e. extend less than four inches into a surface on which it is placed.
  • Surface mounted barriers are easy and fast to deploy when compared to barriers that are integrated with the ground, such as those including posts that extend into the surface on which the barrier is placed. Additionally, such barriers can readily be moved, if desired.
  • the increase in energy transfer of the arrangement of the present invention means that a surface mounted barrier can effectively resist a vehicle ramming attack.
  • the individual barrier units may comprise containers, such as gabions.
  • the containers or gabions may be open-topped or may comprise a lid.
  • Possible structures of suitable gabions are well known in the art and are generally made from wire mesh panels, which form side walls and a base, thereby creating a gabion cage.
  • the gabion may include a higher front panel relative to the back panel, which would make it harder for an individual to overcome the barrier.
  • Suitable barrier arrangements are shown, for example, in WO2008/020247, WO2007/060476 and WO2011/012879.
  • the connecting means may comprise helical coils wound between the wire mesh of the adjacent barrier units, thereby connecting the two.
  • Such arrangements are cheap and easy to manufacture and are well known in the art.
  • the energy transfer means may extend through the holes in the wire mesh of the gabion side walls. This helps to maintain the energy transfer means in the correct position and is cheap and easy to manufacture. Additionally, this means that the energy transfer means is present within the barrier units. As discussed above, this prevents the formation of a surface on the outside of the barrier that may help an individual climb over it.
  • the energy transfer means may be connected to each individual barrier unit using a nut, a clamp or other fastening means that are known in the art. Additionally, a plate may be positioned between individual barrier units. The energy transfer means can then extend through the plate, which may be made of metal or an alloy. This is particularly beneficial if the individual barrier units comprise side walls, such as are present in gabions. In this case, the plate may be placed between side walls of adjacent individual barrier units and the nut or other fastening means may be attached to the energy transfer means on the opposite side of the side wall, i.e. inside the gabion cage.
  • the barrier units may comprise further components, in addition to the gabion or other container.
  • one or more supports may be connected to the gabion or other container, which may extend higher than the height of the gabion or other container.
  • the support may comprise a post, which may be vertical and may further comprise a base portion.
  • the support may act as a brace.
  • a fence panel may be attached to said support at the front of the barrier unit, which may increase the height of the front of the barrier unit.
  • the energy transfer means may be connected to the support.
  • the connection may comprise a nut, a clamp or another fastening means.
  • the barrier unit may comprise one or more gabions or other containers that are connected together.
  • the gabions may be lined, optionally with a geotextile material.
  • the gabions may be double-lined.
  • a fill material can then be used to fill the gabion to increase the mass of the individual barrier units. Fill materials such as a well graded sand or rock can be used. This means that fill materials that are readily available at the site of deployment can be used, such as desert fill.
  • the gabions may include a flexible bag within the gabion cage.
  • This bag may be at least partially filled with a fill material either before or after it is placed within the gabion.
  • the fill materials may be as described above.
  • the flexible bag is a fluted bag.
  • Fluted bags include a member within the bag that internally connects one wall to an adjacent wall. This helps the bag to maintain its shape once filled, as square bags without these members expand towards a circular configuration when filled. In contrast, the members hold the walls in the desired configuration, so that they are easier to place within the gabion cage.
  • the flexible bag or the lining material comprises a lid. This acts to prevent the fill material from escaping the bag or liner when a force is applied to the barrier unit, thereby maintaining the weight of the barrier.
  • the flexible bag may be positioned towards the rear of the gabion cage.
  • the rear of the gabion is the elongate side of the linear barrier opposite that to which the force is to be applied.
  • the barrier may further comprise an additional plurality of individual barrier units in a linear arrangement, extending parallel to the first plurality and in contact therewith.
  • the second plurality of individual barrier units extends along the rear of the first plurality.
  • the barrier units in the second plurality may be the same as or different to those in the first plurality. This arrangement allows energy to be transferred from the barrier unit to which the force is applied to the second plurality of individual barrier units as well as the first, thereby further improving the resistance of the barrier to vehicle ramming attack.
  • the second plurality of barrier units also reduces the risk of the first plurality of barrier units rolling backwards upon impact, which can reduce the efficiency of the energy transfer and can result in the barrier being breached.
  • the second plurality of individual barrier units is staggered compared to the first plurality of individual units, such that the connections between adjacent individual barrier units within each plurality do not fall at the same points along the length of the barrier. This further improves the strength of the barrier, thereby improving the resistance of the barrier to vehicle ramming attack.
  • the second plurality of individual barrier units may be connected to the first plurality of individual barrier units.
  • Such connection means may be any means known in the art and may be the same means as is used to connect adjacent individual barrier units within the first and/or second plurality of individual barrier units, as discussed above.
  • the second plurality of individual barrier units may comprise gabions, which may include a bag, as discussed above in relation to the first plurality of individual barrier units.
  • the bag may be positioned towards the front of the gabion cage.
  • the front of the barrier is the elongate side of the linear barrier closest that to which the force is to be applied.
  • the gabions in both pluralities may include a bag.
  • the bags may be positioned in the gabion cage towards the side of each plurality of gabions adjacent to the other plurality of gabions.
  • One or more individual barrier unit may also comprise a friction increasing means on its base.
  • the base is the side of the barrier unit in contact with the surface on which the barrier is deployed.
  • This barrier unit may be part of the first plurality of individual barrier units and/or the second plurality of individual barrier units (if present).
  • the friction increasing means extends from the base of the individual barrier unit towards a surface on which the barrier is placed. The friction increasing means can therefore interact with a surface on which the barrier is placed. This increases the friction between the barrier and the surface, thereby helping to transfer the energy associated with the force applied to an individual barrier unit away from the individual barrier unit to which it is applied.
  • the friction increasing means is present on all of the individual barrier units in the barrier.
  • the friction increasing means may be any means that extends from the base of the individual barrier unit.
  • the friction increasing means may comprise bolts that extend from the base of the barrier unit.
  • the bolts may extend through a plate, which may be a flat bar plate, on the inside of the gabion cage and then through the holes in the wire mesh.
  • the bolts (or any other friction increasing means) may be held in place by the weight of the fill material placed within the gabion cage, or may be attached to the base of the barrier unit.
  • the friction increasing means may comprise a metal grid with one or more angled surface, such as an expanded sheet metal.
  • the angled surfaces extend from the base of the barrier unit and may dig into the surface on which the barrier is placed when a force is applied.
  • the friction increasing means may be positioned towards the rear of the barrier. This may allow the front of the barrier to lift up as a force, such as a vehicle ramming attack, is applied to the barrier.
  • a trench may be created in front of the barrier in order to decrease and disrupt the amount of energy with which a vehicle can collide with the barrier. This therefore increases the resistance of the barrier arrangement to vehicle ramming attacks.
  • a method of deploying a barrier comprising the steps of deploying a plurality of individual barrier units in a linear arrangement to form a barrier and connecting the plurality of individual barrier units with a relatively rigid energy transfer means, wherein the energy transfer means comprises at least one continuous member extending along the length of the plurality of individual barrier units that is connected to each individual barrier unit in the plurality.
  • This method is quick and easy and provides a barrier with an increased resistance to vehicle ramming attack, as when a force is applied to one individual barrier unit in the plurality, the energy transfer means transfers part of the energy associated with the applied force to other individual barrier units in the plurality of individual barrier units.
  • a kit comprising a plurality of barrier units that can be positioned in a linear arrangement having a length, as well as a relatively rigid energy transfer means wherein the energy transfer means comprises at least one continuous member that can extend along the length of the plurality of individual barrier units and that can be connected to each individual barrier unit in the plurality such that when a force is applied to one individual barrier unit in the plurality, the energy transfer means transfers part of the energy associated with the applied force to other individual barrier units in the plurality of individual barrier units.
  • the energy transfer means may comprise two or more rods (or other elongate members) connected together to form a continuous energy transfer means.
  • the two or more elongate members may have different lengths. This allows the connection between the elongate members to be positioned away from the connection between adjacent barrier units.
  • FIG. 1 illustrates a barrier 1 comprising a plurality of individual barrier units 2 , connected by an energy transfer means 3 .
