Definitions

  • the invention relates to a bulk material surface for sports fields, in particular soccer fields.
  • the invention further relates to a method for producing such a bulk material surface.
  • Sports fields are subject to very high loads when used as intended, especially if the sport is associated with high positive or negative accelerations in the movement of the athletes and / or sports shoes with studs are used. This is especially true for soccer fields.
  • the grip is sufficient for low to medium loads, but usually fails at higher loads due to the curl of the particles the fill.
  • the risk of falling injuries from abrasion / bruising is high. Maintenance, for example by smoothing and rolling, is much easier than that of a lawn.
  • the object of the invention is to provide a bulk material area (also called bulk material bedding) for sports fields, in particular soccer fields, which largely combines the user advantages of a grass field with the maintenance advantages of hard or tennis courts and offers further advantages, in particular with regard to construction costs.
  • a bulk material area also called bulk material bedding
  • This task is based on a bulk material surface or bulk material bedding with a water-permeable, multi-layer superstructure known per se for tennis floors, which - apart from the top or covering layer - preferably a conventional structure (filter layer, base layer) corresponding to the relevant standards (e.g. DIN 18035) , dynamic layer) on a surface or substructure; z. B. in the lower part of the superstructure and / or in the underground or substructure, the usual drainage devices, geotextiles and the like can be used or arranged in a manner known per se.
  • the water-permeable cover layer of the superstructure of the bulk material surface or bulk material bed serving as a covering consists at least predominantly and preferably practically completely of a wood bark material which consists essentially of platelet-shaped parts or particles and which are compacted to form a practically stable top layer.
  • bulk material area is used in the same way as the term “turf area” and means a multi-layer bulk material bed and not a two-dimensional "area” in the geometric sense.
  • Preferred embodiments of the bulk material surface according to the invention have the features specified in claims 2-9, the DIN or SNV standard specifications refer to the respective German or Swiss standard regulations.
  • the method according to the invention for producing the new bulk material surface is characterized in that the top layer is formed on the superstructure produced in the customary manner by pouring on the particulate wood bark material mentioned, the particles are pre-oriented in the course of the bed or subsequently parallel to the horizontal plane and the pre-oriented loose bed is then mechanically condensed.
  • Preferred forms of the method have the features specified in claims 11 and 12.
  • Fresh or at least slightly rotten wood bark material particles are preferably used as the wood bark material.
  • the pre-orientation of the platelet-shaped particles can by appropriate storage methods, for. B. scattering machines, with predominantly parallel particle delivery or by treating the deposited layer, for. B. with rakes can be achieved.
  • the mechanical. Compression can e.g. B. by isostatic rolling and is typically at least about 10% and for example about 30% of the thickness of the loose bed.
  • Wood bark products as they occur in the manual or mechanical debarking of deciduous and coniferous trees both in forestry operations and in industrial tree or wood processing, are a large-scale waste product, its disposal or use, e.g. B. as fuel or for composting, is economically significant. It is also known to use crushed bark material as soft bulk material, for example as so-called mulch material or for riding arenas and playgrounds. In the known uses of bark material as bulk material, however, a loose bed is always sought, i. H. a layer of particles with statistical position distribution; but even in the case of fillings with a more or less pronounced orientation of the particles, an essentially loose particle bed is normally achieved, which has practically no strength when loaded by forces acting parallel or at an acute angle to the surface.
  • the degree of tread resistance desired or required for the top layer of a bulk material surface according to the invention can depend on the desired resilience of the sports field, including the type of sport and the nature of the athletic shoe (e.g. studs); In general, there is sufficient minimum resistance to treading if the sports surface allows at least one game without interruptions due to the surface under the usual load for professional football, and the tread resistance can be increased by taking into account the parameters mentioned below.
  • wood bark materials of various origins deciduous or coniferous trees
  • various types of extraction manual or mechanical debarking
  • Bark and bast material from hard-to-decompose wood, especially hardwood such as oak, and wood bark with a wood content of 10-30% by weight represent a preferred starting material.
  • a platelet-shaped wood bark material suitable for the invention - hereinafter referred to as a mixture for short - the raw material obtained during debarking, if necessary after comminution, can be obtained by known classification methods such as sieving, sifting and the like.
  • classification methods such as sieving, sifting and the like.
  • the devices suitable for this are known to the person skilled in the art for the production of building material mixtures. Bark products of different origins can also be mixed before or after classification.
  • Suitable platelet-shaped parts or particles of the bark material are capable of forming a bed which, if necessary after prior orientation, can be compacted into a layer which, in vertical section, shows an orientation of the particles approximately parallel to the surface of the covering.
  • the wood bark material contains little or no fines, e.g. B. less than 10% by weight of particles with maximum dimensions of less than 6 mm. Particles that are too long or narrow are less suitable, which is why the width: length ratio of a considerable (e.g.
  • 50% by weight or more) fraction is at least 1: 4 and accordingly normally at most 1: 1, otherwise the «widths »Dimension becomes the « length »dimension; finally, the smaller area dimension ("width") of an essential and usually at least 50% by weight part of the wood bark material should be at least three times larger than the thickness of the particles.
  • a certain proportion, preferably at least 20% and in particular at least 50% (in each case based on weight) of the wood bark material is preferably formed by particles which have a maximum thickness of approximately 3 mm and each have a total surface area of more than 300 mm 2 .
  • the classification of particles suitable or preferred for the invention can generally be carried out according to known criteria for the assessment of particle sizes or particle shapes, as described in the relevant standard regulations and can be checked by visual inspection, sieving and the like methods.
  • Wood bark material particles are particularly advantageous which, according to SNV standard 670 / 120a, have a non-uniformity index C u of 10-50 or / and a curvature index C e of 1-3.
  • the bulk material surface or bulk material bed 10 lies on a substructure 11, which either improves the surface, ie the naturally present soil, if necessary, for. B. by mechanical strengthening or with binding agent, or a substructure, that is a heap on the ground, which can also be improved.
  • the base or substructure 11 is leveled in the usual way with the flatness and inclination values customary for sports fields.
  • the filter layer 12 lying above is the first bed layer that normally belongs to the superstructure, but can also be replaced by a geotextile layer. Any drainage devices (not shown) are usually located in or immediately below the filter layer, which is generally intended to prevent sub-surface or sub-construction material softened after frost periods or persistent rain from penetrating into the overlying base layer 13.
  • This base layer should have a sufficiently stable grain structure in order to increase the load-bearing capacity of the covering and furthermore have a pore space which is sufficiently large for rain drainage of the layers above.
  • the installation of a dynamic layer 14 is optional; such layers normally serve mainly to increase the elastic compliance under vertical loads. Since the covering layer 15 according to the invention has a much higher elasticity than conventional turf coverings, the installation of a dynamic layer 14 is usually dispensed with; such a dynamic layer 14 can, however, form a granulometric transition between the covering layer 15 and the base layer 13 and have an additional water storage function.
  • the subsoil or substructure 11 and the surface layers 12, 13 and optionally 14 can be produced and constructed in practically the same way as that of conventional turf surfaces, apart from the covering of the latter.
  • Specific information about suitable thicknesses and compositions of layers 11-14 can be found, for example, in relevant standards, e.g. B. DIN 18035 or the installation recommendations of the suppliers of geotextiles.
  • the top layer 15 typically has a thickness of 5-25 cm, but could also be thicker, and can be applied in one operation. It is preferably applied in at least two work steps, each work step being poured on with simultaneous or subsequent pre-orientation and compacting, e.g. B. with conventional rollers.
  • a comparatively coarser wood bark material for example grain size according to SNV 670 812a to 60 mm, preferably up to 40 mm
  • Wood bark material e.g.
  • grain according to SNV 670 812a up to 30 mm, preferably up to 15 mm can be used in the upper partial layer 151 under its surface 150, for example a 5-10 cm and typically about 8 cm thick wood bark platelet layer with a finer texture and to form a higher tread and surface shear strength or in the lower sub-layer 152, for example a 10-20 cm and typically 15 cm thick wood bark platelet layer with a coarser texture and higher water permeability.
  • the platelet-shaped wood bark material to be used for the top layer 15 can first be loosely sprinkled evenly onto the layer 13 or 14; when using relatively smooth, d. H. this loose layer can already have a certain surface-parallel particle orientation when the pouring devices are not swirling strongly. If this is not the case, mechanical coarse screens can be used.
  • the loose bed of wood bark material for the top layer 15 or its lower sub-layer 152 is processed by compression, typically by about 10-40% and for example 30% of its loose bed height, e.g. B. with a smooth wheel roller of about 1 t / m drum width.
  • a theoretical boundary layer 159 indicated by dash-dotted lines is created, at which the two differently textured partial layers 151, 152 adjoin one another or merge into one another.
  • the entire top layer 15 is preferably saturated several times with water, which, depending on the weather, may require 1-4 liters / m 2 of covering per day. Between the saturation phases it is expedient to carry out repeated densification, expediently until a total pore volume of about 45-70% is reached and a water permeability value of 2.10-3 cm / sec has not yet been reached.
  • the optimum water content of the top layer 15 is approximately 45-50% by weight under normal conditions.
  • the bulk material surface 10 according to the invention is now ready for use as a soccer field.
  • Test pieces taken from the edge of the top layer 15 made of wood bark material show a pronounced grain, i. H. Particle orientation, parallel to surface 150 of cover layer 15.
  • Known red-inhibiting substances can be added to the water used to saturate the top layer 15 or the wood bark material for forming the top layer 15.
  • Elemental sulfur in powder form is a preferred additive for this purpose, e.g. B. in amounts of 0.1-5%, in particular 0.5-3% and typically about 1% of the weight of the bark material, but other substances are also suitable which are practically insoluble in water and in the layer 15 a physiological produce acidic pH of preferably 6 or less and in any case delay the microbiological degradation.
  • the wood bark material or the water used to saturate the layer 15 can if desired, artificial binders (for example an aqueous tar or PVC emulsion) can be added for further solidification.
  • artificial binders for example an aqueous tar or PVC emulsion
  • the use of such binders in considerable proportions is usually neither necessary nor advantageous and can have the disadvantage that the water permeability is reduced excessively.
  • the proportion of artificial binder in the cover layer should be less than 5% by weight, preferably less than 1% by weight.
  • the resin which is usually present in relatively high proportions in wood bark material, is often sufficient for sufficient top layer strength and is not included in the artificial binder.
  • the addition of special red-inhibiting substances to the top layer 15 is not particularly critical if it contains considerable portions of bark material which contains a large amount of tannins or has a similar preservative effect (“Gerberlohe”), as is typical for hardwoods such as oak.
  • the invention offers advantages in terms of space and maintenance costs, since the bark material is comparatively cheap, but the covering produced with it is comparatively stable and generally does not require any particularly high maintenance expenditure. Detached covering parts can usually easily, e.g. B. with trawls or by rolling back in the layer and usually leave no holes, but comparatively harmless because of flat depressions.
  • the finished top layer 15 Since the swellability of bark material is comparatively low, a compacted top layer 15 does not lose its porosity due to swelling.
  • the finished top layer 15 z. B. have a water absorption value of at least 2 ⁇ 10 -3 cm / sec and a pore volume of 45-50 vol.% Determined according to DIN 18 035, Part 5, which can normally be achieved with the above-mentioned bark materials or installation conditions.
  • a typical cover layer 15 of 5-20 cm thickness produced according to the above information has a comparatively high resilience and is nevertheless practically completely sturdy, so that all movement sequences typical of football and comparable sports remain unimpeded.
  • the risk of bumping and crushing injuries when falling can be significantly reduced compared to hard or hard lawns and the risk of abrasions can be virtually eliminated.
  • Another considerable advantage of the invention, particularly in the case of soccer fields, is that raining immediately before or during the game does not normally lead to a deterioration in the example, ie no “heavy ground” arises; it may even be expedient to spray water on a football field according to the invention immediately before a game.
