Definitions

  • Barrier element to block traffic and/or as a security precaution including a ballast compartment
  • the present invention relates to a barrier element to block traffic and/or as a security precaution, comprising: an elongated casing with two opposing longitudinal side walls and an, the two side walls joining, upper wall; at least one casing support structure located in the elongate casing and connecting to both the side walls; and supports for resting on the ground/surface connected to the lower side of the elongate casing and/or the lower side of the casing support structure.
  • the invention also relates to a method for making ready for use of such a barrier element.
  • Barrier elements are installations set up to control or block traffic, e.g. during roadworks, temporary road closure, as a security precaution and/or as Hostile Vehicle Mitigation (HVM).
  • HVM Hostile Vehicle Mitigation
  • barrier elements for bounding carriageways are well known and widely used. These barrier elements are typically connected end-to-end to form an elongated barrier to protect traffic from roadside obstacles or hazards or to prevent vehicles from crossing over a median and striking an oncoming vehicle. Due to their elongated casing, these type of barrier elements may be individually freestanding or coupled freestanding and are preferably easy to deploy, making them suited for temporary use.
  • barrier elements may also be more (semi-)permanently fixed to a roadbed (or other artificial construction like for instance a bridge or ramp) in situations where only a limited deflection distance is allowed.
  • Such (semi-)permanently fixed barrier elements are also referred to as “minimum deflection barrier systems”.
  • a barrier element is easy to install and remove, as well as easy to transport and store. These demands may for instance be provided by an elongated element substantially shaped as a traffic barrier, which traffic barrier may - or may not - be firmly connected to the ground or surface.
  • a further elementary requirement of a barrier element is that it provides an essential blocking functionality as it has to be able to handle the forces exerted on the barrier element exerted by a vehicle that collides with the barrier element.
  • the blocking functionality may be provided by the combination of various technical features like the shape of the barrier element, the weight (mass) of the barrier element, the connection(s) of the barrier element with the surface and/or one or more adjoining barrier element(s).
  • barrier element Even when one or more of the possible connections break, disconnect and/or detach due to a considerable force being exerted on the barrier element as a result of the impact of a vehicle onto the barrier element, the barrier element still is required to fulfil a blocking function.
  • road side barriers often absorb at least part of the kinetic energy of a colliding object, specifically a vehicle, contacting a barrier.
  • Common barrier elements hereby partially plastically deform as a method to dissipate the kinetic energy.
  • the barrier must on the other hand be sufficiently rigid to retain its barrier function.
  • barrier elements with a higher weight provide a better functionality than lighter barrier element (on the basis of the inertia provided by the barrier element) but that heavier barrier elements are less easy to transport.
  • the enhance functioning of the barrier element according the present invention is further a result of the increased friction between the heavier barrier and a road surface.
  • ballast compartment in itself does not substantially add to the weight of the barrier element but it enables to be filled with a curing material at a first location of use (or close to the first location of use of the barrier element).
  • the ballast compartment may stay empty (thus without holding any ballast).
  • the barrier element with initial empty ballast compartment has the advantage that the handling is the barrier element is before filling the ballast compartment with the ballast simpler, cheaper as it requires - due to the lower weight - less from the handling, transportation and/or storage means.
  • the ballast compartment may - in an upside down orientation of the barrier element - locally simply be filled with liquid curing ballast material so that the weight of the barrier element substantially grows,, which higher weight provides an enhanced functionality compared to the lighter barrier element with unfilled ballast compartment due to the additional inertia of the barrier element.
  • the barrier element according the invention thus combines the advantages of a lighter barrier element in the first stage of its life cycle and the advantages of a heavier barrier element during the intended use of the barrier element.
  • ballast compartment supports the dimensional stability of the construction of the barrier element, both in filled and in unfilled condition.
  • the closed top and closed sides are preferably fluid tight connected to each other and are forming together an inverted liquid-tight container with an open underside. This enables the filling of the turned upside down ballast compartment with a curing material without leakage of the curing material when in liquid state.
  • the ballast compartment may have an elongate ballast compartment casing as to distribute the additional weight of the ballast over a length of the barrier element.
  • the length of the ballast compartment comprises the total length, or nearly the total length of the barrier element.
  • the end parts e.g. including couplings
  • the top and sides of the ballast compartment barrier element may be made out of steel made, more specific out of metal sheet material, as in practice steel sheet material is easy to obtain at reasonable prices. Also during the production of prior art traffic barriers and barrier elements often use is made of steel plate material so the production the barrier element according the present invention will normally fit the production facilities of traffic barrier and barrier element producers without the demand for substantive changes of adaptation.
  • At least one of the supports is connected to the underside of two opposed sides of the ballast compartment. Again such an additional connection of parts adds to the structural strength of the construction of the barrier element but as a further advantage hardened ballast material in the ballast compartment may be secured/locked in its position as one or more supports may “lock” the hardened ballast material in its position.
  • the support(s) work as a blockade against the hardened ballast material leaving the ballast compartment.
  • ballast compartment it is advantageous to connect at least one casing support structure to the ballast compartment. Again such an additional connection will enhance the stability and strength of the construction of the barrier element. In case of considerable forces exerted onto the barrier element these forces will better be absorbed in case the support structure is “backed up” by the ballast filled ballast compartment.
  • the ballast compartment may also be provided with one or more internal protrusions.
  • the advantage of such protrusion(s) may be that - as also referred to in relation to the compartment attached supports above - hardened ballast material in the ballast compartment may be secured/locked in its position as one or more protrusions may hold the hardened ballast material form-fitting in its position.
  • the protrusion(s) may work as a blockade against the hardened ballast material leaving the ballast compartment.
  • the ends of the elongated casing may be provided with couplings. These may be connected to the ballast compartment (or alternatively formulated to a side and/or the top of the ballast compartment to provide additional strength and stability of the structure of both, the individual barrier elements, as well as a row of at least two mutual coupled barrier elements).
  • the ends of the elongated casing may be chamfered. This also provides additional strength to the construction and prevents the chance of unwanted contact of road users (pedestrians, cyclists, guards) with the barrier element.
  • the present invention relates not only to the barrier element with an empty ballast compartment as well as the barrier element wherein the ballast compartment is filled with a curing material.
  • the barrier element is suited to be used in circumstances in wherein the loads exerted onto the barrier element may be heavy.
  • a suited curing material may be concrete as it is easy and relatively cheap to obtain and prepare at most locations in the world. Further advantages of concrete is that it is relative heavy and it is also very suitable for absorbing pressure loads.
  • an additional reinforcement in the concrete e.g. a (metal) fibre
  • to make the concrete suited to withstand substantial tension forces is superfluous as the ballast compartment will function as an external length that may be provided by the ballast compartment.
  • the barrier element according the present invention may also be provided with at least one, but preferably at least two, lifting couplings (e.g. in the form of openings in the top providing access to a gripping element) to enable to attach a manipulator (e.g. a crane) for instalment and/or removal of the barrier element.
  • a manipulator e.g. a crane
  • the present invention also provides a method for making ready for use of a barrier element according to the present invention, comprising the method steps: A) placing the barrier element is brought in an inverted position; B) filling the ballast compartment with a liquid curing material; C) hardening the curing material; and D) turning the barrier element back to a working position.
  • the filling of the ballast compartment is easy via the open bottom and will increase the weight and stability of the barrier element enhancing its usage options.
