Abstract
Description
L'invention est relative à la fabrication de terrains de sport, notamment de terrains ou courts de tennis. The invention relates to the manufacture of sports grounds, in particular tennis courts or grounds.
Pour établir un court de tennis dit "en dur", on creuse le terrain sur une surface et une profondeur appropriées, on le draine, par exemple au moyen de tuyaux ou drains placés dans des tranchées creusées au fond de la fouille et reliés à un drain collecteur, on dépose une couche ou "forme" de sable mélangé à du gravier qui est compactée, par exemple par vibrations, On établit ensuite une couche de béton poreux constitué par du gravier et du ciment Vlst, Portland ou autre, généralement suivant une multiplicité de dalles adjacentes formant ainsi un quadrillage. To establish a so-called "hard" tennis court, the field is dug to an appropriate surface and depth, it is drained, for example by means of pipes or drains placed in trenches dug at the bottom of the excavation and connected to a collector drain, a layer or "form" of sand mixed with gravel is deposited, which is compacted, for example by vibration, A layer of porous concrete is then established, consisting of gravel and Vlst, Portland or other cement, generally according to a multiplicity of adjacent slabs thus forming a grid.
Cette couche de béton poreux, dans certains courts de tennis, est couverte d'un revêtement comprenant du gravier à grains concassés. Ces grains, bruts de carrière, forment une surface extremement râpeuse qui, pour ne pas provoquer une usure trop rapide des bailles, doit être poncée. Mais la surface alors obtenue est glissante et désagréable pour le joueur. This layer of porous concrete, in some tennis courts, is covered with a coating comprising gravel with crushed grains. These grains, rough from the quarry, form an extremely rough surface which, in order not to cause too rapid wear of the yokes, must be sanded. But the surface then obtained is slippery and unpleasant for the player.
C'est un but de l'invention de fabriquer un court de tennis en dur, qui ne présente pas les inconvénients rappelés ci-dessus, et fasse appel à des matériaux bon marché. It is an object of the invention to manufacture a hard tennis court, which does not have the drawbacks mentioned above, and uses inexpensive materials.
Dans le procédé selon l'invention, la couche de béton poreux, après avoir été arasée, puis vibrée à des fins de compactage, est couverte d'une deuxième couche de béton poreux dont l'agrégat est un matériau à grains arrondis. On utilise avantageusement un matériau alluvionnaire basaltique et/ou siliceux, arrondi par l'érosion naturelle, tel qu'obtenu après tamisage jusqu'à une granulométrie aux alentours de 4,5 mm. In the method according to the invention, the layer of porous concrete, after having been leveled, then vibrated for compacting purposes, is covered with a second layer of porous concrete, the aggregate of which is a material with rounded grains. Advantageously, a basaltic and / or siliceous alluvial material is used, rounded by natural erosion, as obtained after sieving to a particle size of around 4.5 mm.
Le fait d'utiliser des grains arrondis noyés dans du béton poreux en tant que couche de revêtement permet d'obtenir une surface non abrasive, diminuant ainsi l'usure des balles et qui, simultanément, est agréable pour le joueur. En particulier, il a été constaté qu'une surface comprenant des grains arrondis est peu glissante et que l'eau de pluie s'élimine rapidement. The fact of using rounded grains embedded in porous concrete as a coating layer makes it possible to obtain a non-abrasive surface, thus reducing the wear of the balls and which, simultaneously, is pleasant for the player. In particular, it has been found that a surface comprising rounded grains is not very slippery and that rainwater is quickly eliminated.
On peut utiliser divers matériaux, dans la mesure où ils sont sous forme de grains arrondis, avantageusement criblés pour présenter une granulométrie uniforme. Various materials can be used, insofar as they are in the form of rounded grains, advantageously screened to have a uniform particle size.
La description ci-après se réfère à la figure unique du dessin annexé qui est une vue schématique en coupe d'un court de tennis fabriqué conformément à l'invention. The description below refers to the single figure of the accompanying drawing which is a schematic sectional view of a tennis court made in accordance with the invention.
Sur le fond 1 de la fouille effectuée sur une aire appropriée et sur une profondeur d'environ 30 à 40 cm, et qui comprend en général 11 enlèvement de la terre végétale, et après pose d'un système de drainage approprié usuel, on dépose une "forme" 2 à surface supérieure bien horizontale, constituée de sable mélangé à du gravier. Cette forme 2 est posée sur une épaisseur de 25 à 40 cm suivant la nature du sous-sol. On the bottom 1 of the excavation carried out on an appropriate area and to a depth of about 30 to 40 cm, and which generally includes 11 removal of topsoil, and after installation of a usual suitable drainage system, one deposits a "shape" 2 with a very horizontal upper surface, consisting of sand mixed with gravel. This form 2 is laid on a thickness of 25 to 40 cm depending on the nature of the basement.
Après compactage de la forme 2, on réalise une première dalle en béton poreux 3. Cette dalle est en fait composée de plusieurs dalles adjacentes formant un quadrillage, en général de trente-six dalles. Le béton poreux est constitué à partir de granulats de 5/15 mm et de ciment Vicat, par exemple Vicat 445, ou Portland, à raison d'environ 3QO kg de ciment par mètre cube d'agrégat. After compacting the form 2, a first porous concrete slab 3 is produced. This slab is in fact composed of several adjacent slabs forming a grid, generally thirty-six slabs. The porous concrete is made from aggregates of 5/15 mm and Vicat cement, for example Vicat 445, or Portland, at a rate of approximately 30 kg of cement per cubic meter of aggregate.
On utilise avantageusement un agrégat alluvionnaire, par exemple de la migonnette mélangée à du gravier et de granulométrie 5/15. Advantageously, an alluvial aggregate is used, for example migonnette mixed with gravel and grain size 5/15.
La couche de béton 3, coulée sur une épaisseur d'environ 8 cm, est alors arasée puis vibrée mécaniquement ou a la main. The concrete layer 3, poured over a thickness of about 8 cm, is then leveled and vibrated mechanically or by hand.
Après compactage, l'épaisseur de la couche de béton est réduite de 3 cm.After compaction, the thickness of the concrete layer is reduced by 3 cm.
On coule alors sur l'épaisseur restante de 3 cm une couche de revêtement 4, constituée, conformément à l'invention, par un béton poreux de matériau granulaire alluvionnaire, à particules arrondies, le ciment étant du Vicat 45 ou 55, par exemple, ou du Portland, utilisé à raison d'environ 350 kg par m3 de matériau granulaire. A coating layer 4 is then poured over the remaining thickness of 3 cm, constituted, in accordance with the invention, by a porous concrete of alluvial granular material, with rounded particles, the cement being Vicat 45 or 55, for example, or Portland, used at a rate of approximately 350 kg per m3 of granular material.
On utilise un matériau basaltique et/ou siliceux, arrondi par l'érosion naturelle, qu'on peut trouver facilement en carrière, principalement en Auvergne, et qui est retamisé pour obtenir une granulométrie d'environ 4,5. A basalt and / or siliceous material is used, rounded by natural erosion, which can easily be found in quarries, mainly in Auvergne, and which is re-screened to obtain a particle size of approximately 4.5.
La couche de revêtement est ensuite tirée à la règle puis roulée. The coating layer is then drawn with a ruler and then rolled.
On applique alors sur la surface de la couche 4 une couche de peinture à laquelle éventuellement ont été associés des produits antidérapants, fongicides, ou présentant d'autres caractéristiques propres à fournir les propriétés souhaitables pour un court de tennis. A layer of paint is then applied to the surface of layer 4, which may have been associated with non-slip products, fungicides, or having other characteristics capable of providing the desirable properties for a tennis court.
