Definitions

  • the invention relates to a composite floor covering according to the preamble of claim 1 and to a road shoulder or a road surface which is designed as such a composite floor covering.
  • Composite floor coverings for open spaces with a mineral granulate bound with a polymer material are known from the state of the art.
  • polymer granulate can also be provided in a bound or unbound form.
  • a water-permeable stone composite molded body which consists of 99 to 65 percent by weight of granules made of mineral plastics with a grain size of 0.5 to 100 mm and 1 to 35 percent by weight of a two-component polyurethane adhesive.
  • a masonry can be provided for building gabion stone basket walls, whereby the stones are vibrated within the gabion stone basket or are firmly connected to one another with filling material or by means of binding materials.
  • a roadside verge is also known, whereby the basic body of the verge consists of a mixture of stone, sand, humus and numerous other elements, which is covered by a layer of geotextile. This ensures such a stable Vegetation layer is designed so that it can also be used on roadside verges or as parking spaces without vehicles sinking into the grass.
  • the DE 41 30 768 C1 discloses a bearing and support cushion for earth and road construction.
  • the core material is covered by a geotextile or random fiber fleece, and it is also proposed to provide geotextile layers within the support cushions that run over parts of the cross-section.
  • the EP 1 464 756 A1 A structure for a playground can be seen, whereby the layer structure is reinforced by geotextile layers.
  • composite floor coverings made of mineral granules and polymer material have been criticized for their environmental impact because of the polymaterial. Even with bound polymaterial, abrasion is unavoidable, meaning that microplastics end up in the environment.
  • a filter system for filtering ions, complexes or other particles from an aqueous flow.
  • the filter device can be made of different materials, such as sand, polymer material, ash, perlite or a solid, porous matrix, such as CPP (Cementious porous pavement).
  • the CPP is preferably porous enough so that water can flow through the pores.
  • a road shoulder can be provided with such a CPP, for example.
  • Membrane filters with a pore size in the order of 0.1 to 50 microns and even up to 3000 or more microns are disclosed as another filter material. This membrane material is preferably made of cellulose.
  • the GB 2 416 130 A shows a structure for a floor covering in which different grain materials are used.
  • a fleece can be used, among other things.
  • the GB 2 396 379 A refers to a floor covering for draining water, which is made up of different layers.
  • a surface layer can be porous asphalt or porous concrete.
  • the porous asphalt can contain bitumen, whereby the bitumen can be interspersed with a polymer, and granular aggregates. Under the surface layer there are further coarser layers and a semi-permeable membrane.
  • the membrane is a synthetic woven geotextile membrane.
  • a laminated geotextile is made up of a number of layers and is intended for use as a filter and/or drainage layer.
  • the layers include woven or non-woven geotextiles made of different materials with different strengths and pore sizes.
  • the CN 106 565 175 A discloses a floor covering made up of several layers for draining or storing water, whereby the layers are characterized by different material compositions.
  • the materials range from concrete to quartz sand to polyurethane.
  • a water-permeable geotextile is provided between a base layer and the layer above.
  • EP 1020566 A2 describes a device and a method for restoring the water permeability of a porous paving surface layer of a drainage system or a water-permeable paving.
  • a high-pressure water jet is ejected onto the surface to clean clogged air pores.
  • the EP 2210982 A2 has a mobile high-pressure cleaning machine for outdoor plastic floors.
  • the high-pressure cleaning machine has a spray device for spraying water under high pressure against a floor surface to be cleaned and a collection device for collecting sprayed water and dirt using suction air.
  • the task is therefore to create a composite floor covering that is very environmentally friendly and can provide a filtering effect in the long term.
  • the porous composite floor covering or polymer covering is provided which is provided with at least one filter fleece section and which consists of a mineral granulate which is bonded to the polymer material to form a porous composite floor covering.
  • the composite floor covering is characterized in that several filter fleece sections are arranged in the composite floor covering, wherein the filter fleece sections are arranged in at least two levels are arranged offset from one another and overlap in the vertical projection and wherein the filter fleece sections have a pore size of not more than 100 ⁇ m.
  • a fleece is preferably arranged at least on the underside of the covering, whereby the fleece can be provided with a pore opening of no more than 100 ⁇ m.
  • the porous composite floor covering has a first filtering effect for coarse-grained materials, such as sand. This is retained in the pores of the composite floor covering. Fine dust, including microplastics, is washed by water through the composite floor covering to the fleece and held there, thus preventing it from entering the environment.
  • the fleece thus serves as a second filter to capture fine dust and other fine particles.
  • the composite floor covering can be cleaned at regular intervals.
  • a high-pressure water jet is pressed into the composite floor covering and the water is sucked out again using a suction device.
  • a composite floor covering made of mineral particles bonded to a polymer material can, on the one hand, have the necessary coarse porosity required to filter coarse particles and which allows water to be pressed in, and, on the other hand, is so stable that such a cleaning process can be carried out repeatedly with water under high pressure.
  • porous floor coverings in which the particles are bonded to a mineral binding agent, for example cement-based. Large pores can also be provided here.
  • mineral binding agents are not elastic, which means that they break and are destroyed when cleaned with water under high pressure. With such floor coverings, the particles would come off during repeated cleaning.
  • a porous composite floor covering which is made of a mineral granulate and an elastic polymer material, and a fleece with a small pore size allows the filtering of coarse and fine substances and can be cleaned regularly, so that a long-term filtering effect is possible.
  • the fleece has a pore size of no more than 100 ⁇ m. It can also be made even finer and preferably no more than 50 ⁇ m in order to reliably retain the microparticles and fine dust.
  • the coating can be removed after its service life and disposed of properly.
  • the surface can be used for road shoulders.
  • the composite floor covering according to the invention can be used to produce water-permeable, open-pored bound road shoulders as well as car parking areas and retention systems for surface drainage (troughs, ditches, infiltration basins) of the roadways and parking areas.
  • the composite floor covering can also be used as a sports floor covering, in particular tennis court or football field covering, where a fine-grained granulate can be loosely applied to this to correspond to a conventional sand court.
  • This granulate can be a plastic granulate or sand granulate. This can lead to plastic abrasion, which is caught by the fleece. The coarse-grained plastic granulate is rubbed off during use, so that fine-grained abrasion occurs. The sand granulate causes fine-grained abrasion on the composite floor covering.
  • a cleaning device not according to the invention can be provided for cleaning a composite floor covering as explained above, wherein the cleaning device has a cleaning nozzle for forcing water or an aqueous solution into the porous floor covering and a suction device for sucking the water out of the floor covering.
  • the cleaning device preferably has a filter device for filtering the extracted water. This allows the water to be reused and a concentrate of dirt to be collected. This is particularly useful when the cleaning device is arranged on a street cleaning vehicle.
  • the cleaning device can have a suction or pressure bar in which one or more cleaning nozzles and/or one or more suction nozzles are integrated.
  • the suction or pressure bar has a length of at least 30 cm and preferably at least 50 cm.
  • the maximum length of the suction or pressure bar is preferably 1 m or 1.2 m.
  • a street cleaning vehicle for cleaning the composite floor covering as explained above can be provided, wherein the street cleaning vehicle has a cleaning device as explained above.
  • Such a street cleaning vehicle with a suction or pressure bar is preferably designed in such a way that the suction or pressure bar can be arranged at different angles of inclination with respect to the direction of travel of the street cleaning vehicle. This allows the effective width to be changed by tilting the suction or pressure bar and to be adapted to the width of the section to be cleaned, in particular the road shoulder to be cleaned.
  • a first embodiment of a composite floor covering 1 is explained below, which forms a banquet ( Figure 1 ).
  • the composite floor covering 1 is made of a mineral granulate and a binding agent.
  • the mineral granulate includes, for example, gravel and/or splinters (soft and hard rocks such as limestone, diabase, basalt, gneiss).
  • the mineral granulate can consist of a grain mixture of 2/5 mm (i.e. a grading curve between 2 mm and 5 mm), 4/8 mm or 8/16 mm, with a proportion of fine-grained material up to 0.2 mm preferably amounting to a maximum of 10% of the mass weight of the rock in the covering.
  • the grading curve is determined individually depending on the load and requirements of the respective trade.
  • the binding agent can be made from a 1-component or 2-component coating material, for example based on polyurethane.
  • a 1-component or 2-component coating material for example based on polyurethane.
  • other polymers such as those based on epoxy, polyethylene, polypropylene, etc., are also suitable as binding agents.
  • a composite floor covering made from these polymers is resistant to frost and de-icing salt.
  • the binding agent is between 3% and 5% by mass.
  • the binding agent's mass proportion should not be greater than 10% in order to ensure sufficient porosity of the composite covering.
  • the greater the binding agent's mass proportion the lower the porosity of the composite covering 1 is as a rule. If the binding agent's mass proportion is very low, this can impair the strength of the composite covering. It is therefore advisable to provide a binding agent's mass proportion of the composite covering of at least 1% and in particular at least 2%.
  • the composite floor covering 1 can be designed with a void content of at least 20% by volume, preferably at least 25% by volume and in particular at least 30% by volume.

  • the pore size for a grain mixture of 4/8 mm is a maximum of 10 mm.
  • the minimum pore size is generally in the range of 0.5 to 3 mm. This means that there is a high water permeability and a good filtering effect for coarse particles.
  • a filter fleece 2 is provided as a filter medium for fine particles.
  • the filter fleece is preferably designed with a minimum weight of 250 g/m 2.
  • the weight of the filter fleece can also be significantly higher.

  • the porosity can also be smaller and limited, for example, to a maximum of 75 ⁇ m or 50 ⁇ m or 25 ⁇ m or 20 ⁇ m.
  • Such filter fleeces are available from Noravin.
  • the porosity of the composite material is one or more orders of magnitude greater than that of the filter fleece. This ensures that water flows through the composite material in sufficient quantities and is filtered by the filter fleece.
  • the pore size of the filter fleece is preferably larger than 10 ⁇ m. This ensures sufficient water permeability.
  • the filter fleece is laid under the composite covering 1, which forms a shoulder, and is pulled up on the flanks to the shoulder surface.
  • the composite floor covering 1 has, in addition to the filter fleece 2, also internal filter fleece sections 3.
  • These internal filter fleece sections 3 can be designed with different porosities than the filter fleece 2 and thus serve for coarse and fine filtration.
  • the composite floor covering 1 rests on an unbound base layer 5. At the edge area, it rests with an edge section on a bound base layer 6 (asphalt ...), which is arranged horizontally abutting the composite floor covering, with the surfaces being flush or forming a continuous transition.

  • the topsoil can have the same incline, be even more inclined, or be less steep and even horizontal.
  • the width of the composite floor covering is based on the RVS specifications for banquets.
  • the filter fleece 2 is arranged at least on the entire underside of the composite floor covering and is pulled up and installed like a trough at the joint areas to the supporting layer 6 and the topsoil 4.
  • the filter fleece 2 thus forms a channel-shaped trough.
  • the inner filter fleece sections 3 are designed as strip-shaped sections which extend in the longitudinal direction of the composite floor covering. They are arranged, for example, parallel to the underside of the composite floor covering.
  • the composite floor covering 2 has a minimum thickness of 8 cm according to RVS. However, for other applications of the composite floor covering, the minimum thickness can also be lower.
  • the specific design of a verge depends on the requirements of the respective JDTV classes, which are determined according to the respective traffic volume (vehicles in 24 hours).
  • the design of the composite floor covering can vary accordingly.
  • the road shoulder is designed with an incline of approximately 5° to 10° relative to the roadway and has a
