Abstract

The pitch has an infra-structure which is an underground network of inclined channels that are covered by a grid. The rest of the surface is covered with a layer of concrete which is 10-12 cm thick. The concrete is covered with a grooved layer in hard plastics material. An artificial perforated mat made of elastic material, such as natural or artificial rubber, covers the whole surface. The mat's upper surface has conical projections of the same material or strengthened with nylon, or other threads. Hot air can be circulated through the channels.

Description

L' invention se réfère à un terrain artificiel de football et d' Athlétisme de dimensions habituelles, qui rem­placera le terrain existant de tapis en gazon naturel.The invention relates to an artificial football and athletic field of usual dimensions, which will replace the existing field of natural grass carpet.

Les terrains de football ou d' athlétisme qui sont utilusés à nos jours sont avec tapis en gazon naturel et très peu a vec sol en plasique. Le sol de ces deux terrains a le désacantage qu'il ne peut pas dégager dépuis la surface la pluie et la neige.The football or athletic fields which are used nowadays are with natural grass carpet and very little with plastic soil. The soil of these two terrains has the disadvantage that it cannot clear from the surface rain and snow.

La construction de ce terrain artificiel se réfère aux éléments suivants :The construction of this artificial ground refers to the following elements:

On enlève de la surface le tapis en gazon existant.The existing grass carpet is removed from the surface.

On compresse à l' aide d'un paveur le sol.The soil is compressed using a paver.

Le terrain ainsi formé ABCD ( Schéma 1 ) est separé en deux parties égales avec une ligne EF ( schéma 1 ). Dans les parties du terrain AEFD et EBCF en des canaux inclinés, dista ncés de 2 à 3 mètres entre eux et lesquels commencent dépuis la ligne EF et finissent aux cotés AD et BC ( schéma2).The ground thus formed ABCD (Diagram 1) is separated into two equal parts with a line EF (diagram 1). In the parts of the ground AEFD and EBCF in inclined channels, separated by 2 to 3 meters between them and which start from the line EF and end at the sides AD and BC (diagram2).

La profondeure et la largeure des canaux seront a­adaptées selon les buts et bésoins poursuivis.The depth and width of the channels will be adapted according to the goals and needs pursued.

On revêt les trois surfaces intérieures des ca - naux avec du béton de 10 cm. d' épaisseur , tout en sauve­gardant l' inclinaison de leur forme.The three interior surfaces of the channels are coated with 10 cm concrete. thick, while saving the inclination of their shape.

On couvre le restant de la surface du terrain avec du béto n de 10 - 12 cm. d' épaisseur, légerement armé et en formant une surface parfaitement horizontale.The rest of the ground surface is covered with 10-12 cm concrete. thick, lightly reinforced and forming a perfectly horizontal surface.

Les canaux sont couverts d' une grille constituée soit de matière plastique dure , soit de duraluminium (sché­ma 3 ).The channels are covered with a grid made either of hard plastic or of duraluminium (diagram 3).

La surface entière du terrain , sauf celle des ca­naux , est couverte d' une couche cannelée constituée de ma­tière plastique dure ( schéma 4 ) .The entire surface of the land, except that of the canals, is covered with a grooved layer made of hard plastic (diagram 4).

Les sillons de cette couche aboutissent aux canaux.The grooves in this layer lead to the canals.

A chaque côté AD et BC on creuse un canal incliné de prpfondeur et largeur analogue aux bésoins et buts (sché­ma 5 ) .On each side AD and BC, an inclined channel of depth and width similar to the needs and goals is dug (diagram 5).

Ces canaux vont recevoir l' eau des petits canaux ( schéma 6 ) .These canals will receive water from the small canals (Figure 6).

En suite ces eaux seront évacuées soit vers le ré­seau de deversement de la ville , soit vers deux puits (sché­ma 7 ).These waters will then be evacuated either to the city's drainage network, or to two wells (Figure 7).

Dans ces petits canaux se trouve une installation permanente de pluie artificielle dont les extrémités auront la possibilité de sortir automatiquement des petits canaux à la surface du terrain et d' y revenir.In these small canals there is a permanent installation of artificial rain, the ends of which will have the possibility of automatically leaving and returning from the small channels on the surface of the ground.

Aux quatre côtés externes du terrain existent des installations permanentes de p̂luie artificielle. Comme pluie artificielle on utilise : 1) l' eau du réseau public , 2) de l'eau salée d' un reservoir existant, tous les deux en tempé­rature naturelle ou chauffée. Si la pression de l' eau de vil­le est petite on utilise des compresseurs.On the four external sides of the site, there are permanent artificial rain installations. As artificial rain we use: 1) water from the public network, 2) salt water from an existing reservoir, both at natural or heated temperature. If the city water pressure is small, compressors are used.

Sous les gradins existe une installation de clima­tisation laquelle avec des installations existantes dans les petits canaux procure de l' eau chaude à l' atmosphère de la surface du terrain.Under the stands there is an air conditioning system which with existing systems in small canals provides hot water to the atmosphere of the land area.

Sur la surface entière du terrain, on installe tapis troué constitué de matière élastique de provenance naturelle ou artificielle , de qualité parfaite et de couleur vert ou autre, lequel se constitue de deux niveaux de grilles posi­tionnées l' une sur l' autre perpendiculairement , chacune de largeur et d' hauteur de 0,002 m. à 0,006 . et en formant ain­si une surface trouée avec comme dimension des trous de 0,002 à 0,006 m. ( schéma 8 ) .On the entire surface of the ground, we install a perforated carpet made of elastic material of natural or artificial origin, of perfect quality and green or other color, which consists of two levels of grids positioned one on top of the other perpendicularly, each width and height of 0.002 m. at 0.006. and thus forming a perforated surface with the dimension of holes from 0.002 to 0.006 m. (diagram 8).

Sur la surface supérieure des frilles se situent des élevations coniques de la même matière plastique avec di­mension de base de 0,002 à 0,005 m. , de sommet 0,001m. à 0,003 et de hauteur 0,01m. à 0,07 m. ( schéma 9 ).On the upper surface of the frills are conical elevations of the same plastic with a basic dimension of 0.002 to 0.005 m. , with a height of 0.001m. at 0.003 and height 0.01m. at 0.07 m. (diagram 9).

Ces élevations sont simples ou fortifiées d' un fil en lin ou en nylon ( schéma 10 ).These farms are simple or fortified with a linen or nylon thread (diagram 10).

A l' aide de ce tapis troué et de la surface cannelé située en dessous , l' eau est facilement évacuée vers les pe­tits canaux et ensuite vers le réseau de deversement de la ville.Using this perforated mat and the grooved surface underneath, the water is easily evacuated to the small canals and then to the city's drainage network.

L' avantage de cette invention est que le terrain artificiel n' est pas influencé par la plui ou la neige.The advantage of this invention is that the artificial terrain is not influenced by rain or snow.

Plus concrétement, même si il pleut abondamment plu­sieurs jours et nuits, après cin minutes que la pluie s'ar­rête, sur le terrain il y aura aucune trace d' eau.More concretely, even if it rains abundantly several days and nights, after fifty minutes that the rain stops, on the ground there will be no trace of water.

Mais dans le cas où la pluie persiste, alors il se­ra possible pour les joueurs de continuer le jeu sur un ter­rain où il n' y aura par de trace de pluie mais où les joueurs seront mouillés tandis que le tapis présentera une humidité relative.But in case the rain persists, then it will be possible for the players to continue the game on a ground where there will be no trace of rain but where the players will be wet while the carpet has relative humidity.

Dans le cas où le terrain sera couvert de neige de quelques centimètres jusqu'à plus qu'un mètre, le systè­me permanent de pluie artificielle se met en marche et la neige dans une petite période fond et s' évacue en forme d' eau de pluie, dépuis la surface du terrain à l'aide du tapis troué.In the case where the ground will be covered with snow from a few centimeters up to more than one meter, the permanent system of artificial rain starts up and the snow in a small period melts and drains out in the form of water. rain, depuis the surface of the ground using the perforated carpet.

Si pendant la durée du jeu il neige, la quantité de neige emmagasinée sur la surface du tapis artificial est inférieure de n' importe autre surface qui reçoit la même quan­tité de neige 1) à cause de la composition du tapis et 2) à cause de la pluie artificielle en eau salé qui vient d'être utilisée.If during the duration of the game it is snowing, the amount of snow stored on the surface of the artificial carpet is less than any other surface which receives the same amount of snow 1) because of the composition of the carpet and 2) because of the artificial salt water rain that has just been used.

Dans ce terrain artificiel il existe un mécanisme de climatisation, sousterrain qui dispense à l' atmosphère de la surface du terrain de l' air chsud à intensité modulable.In this artificial ground there is a subterranean air conditioning mechanism which dispenses to the atmosphere of the ground surface chsud air with adjustable intensity.

En ce qui concerne la dureté - mollesse de la sur - facedu tapis artificiel , si on la compare elle est identique à la dureté-molesse du tapis naturel, lequel se trouve en con­dition identique aux meilleures conditions d' un terrain na­turel et de son tapis en gazon.Regarding the hardness - softness of the surface of the artificial carpet, if we compare it it is identical to the hardness-softness of the natural carpet, which is in identical condition to the best conditions of a natural ground and its carpet in grass.

Nous pouvons aussi, à la surface supérieure des grilles du tapis troué, à la place des élevations poser n'im­porte quelle couche poreuse.We can also, on the upper surface of the grids of the perforated carpet, instead of elevations lay any porous layer.
