Definitions

  • the disclosure relates to a system for assembling a road.
  • the establishment of a road by assembling the road out of parts, wherein modules are available for lining-up and connecting to make the road, has the advantage that the footprint needed for putting down the road is relatively small. Also, the speed by which such a road can be laid is very advantageous.
  • WO 20207022888 A1 describes a system and a method for building such a road. The disclosure further relates to a road.
  • Rainwater that falls onto the road is preferably collected, and somehow guided into a predetermined direction, which may be the direction of a drainage system.
  • a drainage system cannot always cope.
  • the supply of rainwater may simply be too much.
  • the rainwater, then often referred to as stormwater may find its way into underground infiltration systems for temporarily storing the water.
  • W02016/042141 A1 describes an example of such systems. Over time, the water may from such systems slowly permeate into the ground.
  • attenuation systems Such systems do not allow for permeation of water from the underground storage into the ground.
  • the disclosure also relates to a method for capturing traffic produced contamination.
  • the disclosure further relates to use of a system of filters for removing contamination from rainwater.
  • the disclosure relates also to a support structure for use in the system for assembling a road.
  • the disclosure further relates to a road.
  • the disclosure provides a system for assembling a road.
  • the system comprises a plurality of plastic support structures and a plurality of road deck elements.
  • Each of the support structures comprises a base plate and at least one supporting element that extends, or is for extending, upwardly from the base plate for supporting at least partly one of the road deck elements.
  • the system is such that when rainwater falls onto the road, it predominantly flows away over the road to one or more rainwater collection points adjacent each support structure and/or each road deck element.
  • the plurality of plastic support structures comprises a multi-functional support structure which is provided with at least one filter for filtering rainwater that has from the one or more rainwater collection points entered a treatment volume. At least a part of the at least one filter is positioned within that treatment volume.
  • the treatment volume may be spanned by dimensions of the multi-functional support structure.
  • the multifunctional support structure is a one of the plurality of support structures which are present anyway for supporting the road deck elements of the road deck, there is hardly a need, if at all, for enlarging the footprint and/or the volume of the road.
  • the treatment volume is in its entirety within the dimensions of the multifunctional support structure, so that no extra footprint and no extra volume is required for having this facility for removing contamination from rainwater that falls onto the road.
  • the treatment volume may be spanned by dimensions of the multifunctional support structure. This provides for a maximum of capacity for treating the water by filtering etc., without having to enlarge the footprint of the road.
  • the treatment volume may exclude the one or more rainwater collection points.
  • the system in the assembled condition is such that rainwater which is collected by the one or more rainwater collection points and that has entered the treatment volume, includes rainwater which has flowed over at least another area of road deck.
  • the other area of road deck is different from an area of road deck that covers that at least one multifunctional plastic support structure.
  • for filtering all the rainwater that falls down on the road only one out of a plurality of plastic support structures needs to be provided with the at least one filter, making it not only economically viable for making the system, but also economically viable for maintaining the road in that only a relatively small number of the supporting structures will over time need to be assessed for cleaning or replacing the at least one filter, partly or in its entirety.
  • the system in its assembled condition the system is such that rainwater which has been filtered by the at least one filter finds its way away from the treatment volume into other volume.
  • the at least one filter can continuously be in use without a need for consumption of mankind-made energy sources.
  • the filtered water may at least temporarily be kept under the road.
  • the other area of road deck is area of road deck under which no such multifunctional plastic support structure is present.
  • the other area of road deck is area of road deck under which an infiltration system is present for temporarily storing water before it permeates into the ground.
  • Such systems are known systems and assist for instance in the handling of stormwater. When much rain falls in a short period of time and the drainage systems cannot cope with the amount of rainwater, much of that water may quickly find its way into such systems.
  • the system of the present disclosure allows for assembling a road and filtering out of rainwater that flowed over that road the contamination before that rainwater ultimately permeates into the ground.
  • a path for rainwater into such infiltration systems is predominantly, if not exclusively, available via the treatment volume, and even more preferably, via the at least one filter.
  • the other area of road deck is area of road deck under which an infiltration system is present for temporarily storing water before it permeates into the ground
  • an infiltration system instead of an infiltration system, and attenuation system is present under that other area of road deck.

  • TPH Petroleum Hydrocarbons
  • FOG Oils and Grease
  • the treatment volume is underneath the road
  • the collected rainwater is collected from parts of the road which are free from having underneath the road the treatment volume.
  • the parts of the road that are free from having underneath the road the treatment volume have underneath the road an infiltration system for temporarily storing rainwater before it permeates into the ground, or have underneath an attenuation system for temporarily storing rainwater before it finds its way further into sewage system.
  • Rainwater downstream of that relatively fine filter preferably moves thus into an infiltration system or into an attenuation system.
  • the disclosure further provides use of a system of filters for removing contamination from water, wherein the use is preferably in a system for assembling a road.

  • the plurality of road deck elements being supported by a plurality of plastic support structures.
  • Each of the plastic support structures comprises a base plate and at least one supporting element, extending, or for extending, upwardly from the base plate for supporting at least partly one of the road deck elements.

  • the road is provided with a number of fluid communications for replacement of water according to a predetermined route.
  • the rainwater together with the contamination it picked up from the road is less likely to flow directly into the ground underneath and/or next to the road.
  • the fluid communications according to a predetermined route allow for ensuring that the water enters the treatment volume, does pass filters, and then for instance enters an infiltration or attenuation system.
  • the number of fluid communications comprise fluid communications of a first type and fluid communications of a second type, wherein the fluid communications of the first type requires the presence of water to establish the communication under influence of the force of gravity, and wherein the communication of the second type requires the presence of an amount of water in terms of a certain height relative to a height of a structural element.
  • the road has a fluid communication of the first type between the road deck and the one or more rainwater collection points, and has a fluid communication of a first type and/ora fluid communication of a second type between the one or more collection points and the treatment volume.
  • water flows freely from the road and "flushes" with it contamination that was on the road. As soon as it is of the road, the replacement of water is slowed down, and sedimentation of the contamination can start.
  • the road also comprises a fluid communication of a third type which relies on the principle of interconnecting vessels. This allows for removal of contamination that floats on top of water. This type of fluid communication also allows to the removal of contamination that floats in water, for instance when a fine filter is placed in the fluid communication of the third type.

  • the at least one supporting element 6 is in the embodiment shown as an integral structural feature of the structure 4. That is, the supporting element 6 and the base plate 4 form each a structural feature of a one-piece structure 4.

At least one and preferably each supporting element 6 is hollow and cone-shaped and allows for compact stacking onto each other during storage and transport of the supporting structures.
  • the support structures 4, including the supporting elements 6 are each water-permeable, not by the nature of the material but by the presence of perforation in the structure and/or slits, openings etc.
  • the system In an assembled condition, the system is such that when rainwater falls onto the road 1, it predominantly flows away over the road 1 to one or more rainwater collection points CP.
  • the phrasing "flows over the road” is to be understood as contrasting to “flowing into the road or through the road”.
  • the phrasing "predominantly flows over the road” is understood to mean that more than, say 90%, of the water flows over the road, as opposed to flowing into or through the road. Ideally more than 95%, and even more preferably more than 99% flows overthe road.

  • the rainwater mainly flows when a "path" for flowing is available. Although that path is at least partly made available by the force of gravity, this does not mean that the flow is always in the direction of the force of gravity. Structure features may guide the water whilst flowing under the influence of the force of gravity.

  • Another way of describing this aspect is by pointing out the presence of a fluid communication.
  • the fluid communication between the road and the rainwater collection points is referred to as a fluid communication of the first type, which is in this disclosure a fluid communication that requires the presence of waterto establish a communication underthe influence of the force of gravity.

  • the inlet gutter 7 streamlines in a traffic direction A of the road 1 a flow of rainwater of which at least a large amount of rainwater has flowed over the road deck of the road.
  • the inlet-gutter can be extending into any other direction, such as for instance, somewhat transvers to the road direction, and does also not need to extend into a straight line.
  • the plurality of plastic support structures 4 comprises a multi-functional support structure 8 which is provided with at least one filter 9 for filtering rainwater that has from the one or more rainwater collection points CP entered a treatment volume TV which is preferably spanned by dimensions of the multi-functional support structure 8.

  • the inlet gutter 7 also collects rainwater that has flowed over the area of road deck 3a, 3b (RD) that covers one of the multi-functional plastic support structures 8. Not only figure 1 but also Fig 12 displays this schematically by means of arrows.

  • the structural element is the lower rim of the opening of the inlet gutter 7 that allows for water to flow into the treatment volume TV. Also the gravity plays a role in this fluid communication.
  • Fig 4 to Fig 12 show various views of the multifunctional plastic support structure 8. From comparing Fig 4 and 5, it is clear that in the assembled condition of the system, the treatment volume TV is in its entirety under area of road deck 3a, 3b that covers that at least one multi functional support structure 8.
