Description

La présente invention concerne un procédé de réalisation d'une pièce d'eau d'agrément à épuration naturelle de l'eau contenue.The present invention relates to a method of making a body of pleasure water with natural purification of the water contained.

L'invention couvre aussi la pièce d'eau ainsi réalisée.The invention also covers the piece of water thus produced.

On connaît des propriétés disposant d'étangs naturels, de cours d'eau existants traversant ladite propriété mais toutes les propriétés n'en disposent pas.There are properties with natural ponds, existing streams crossing the property but not all properties.

Or, la demande des propriétaires est forte dans ce domaine car un bassin d'agrément apporte de très grandes satisfactions pour la vue, pour le plaisir de la baignade en milieu naturel, pour la faune et la flore qui se développent autour de ce micro milieu naturel. Le cycle local présente un effet de synergie par l'évaporation naturelle de l'eau, cette humidité captée par les plantes et arbres disposés et poussant alentour, les systèmes racinaires qui stabilisent le sol et en retour l'ombre fournie.However, the demand of the owners is strong in this area because a pleasure pool provides great satisfaction for the view, for the pleasure of swimming in the wild, for the fauna and flora that develop around this micro environment natural. The local cycle has a synergistic effect through the natural evaporation of water, this moisture captured by plants and trees arranged and growing around, the root systems that stabilize the soil and in return the provided shade.

Il est possible d'apporter des aménagements extrêmement agréables comme des ponts, cascades, rus coulant sur gravière qui sont autant de spectacles et de plaisirs.It is possible to bring extremely pleasant amenities such as bridges, waterfalls, rus flowing on gravel pit that are as many shows and pleasures.

En effet, il existe des constructions telles que les piscines qui permettent la baignade mais uniquement la baignade. Il s'agit d'une construction totalement artificielle, avec des systèmes de traitement de l'eau au moyen de produits chimiques qu'il s'agisse de sels ou de chlore.Indeed, there are constructions such as swimming pools that allow swimming but only swimming. This is a totally artificial construction, with water treatment systems using chemicals such as salts or chlorine.

L'environnement de ces piscines ne peut pas être naturel, tellement peu que les propriétaires de ces piscines les couvrent avec des protections.The environment of these pools can not be natural, so little that the owners of these pools cover them with protections.

De tels aménagements sont réservés à des emplacements de surface plus restreinte.Such developments are reserved for smaller surface areas.

Les objectifs sont donc totalement différents et l'on entend par "pièce d'eau" pour la suite de la description, toute pièce d'eau quels que soient sa taille, son volume, sa profondeur et sa forme.The objectives are totally different and the term "piece of water" for the rest of the description, any body of water regardless of its size, volume, depth and shape.

On connaît des pièces d'eau réalisées à partir de films d'étanchéité en matériau polymère qui tapissent le fond de la pièce d'eau. Eventuellement de la terre est rapportée sur ce film. Dans la première solution, l'eau est stagnante ce qui provoque des désagréments car les dépôts s'accumulent et lorsque la saison chaude est là, il peut y avoir pourrissement des matières végétales avec émission d'odeurs, l'eau n'est jamais claire. Dans une seconde solution connue, l'eau est traitée par trop plein ou pompage dans un système de filtres à cartouches dans des bassins en matériau de synthèse ou en maçonnerie. Dans ce cas, l'eau est claire mais elle requiert un investissement lourd et surtout des consommables qui rendent le cycle de vie d'une telle pièce d'eau très coûteuse en plus du fait de recourir à des filtres en matériau de synthèse qu'il faut ensuite éliminer en décharge.Pieces of water made from sealing films made of polymeric material which line the bottom of the body of water are known. Possibly earth is reported on this film. In the first solution, the water is stagnant which causes inconvenience because the deposits accumulate and when the hot season is there, there may be rotting of vegetable matter with emission of odors, the water is never Claire. In a second known solution, the water is treated by overflow or pumping in a system of cartridge filters in pools of synthetic material or masonry. In this case, the water is clear but it requires a heavy investment and especially consumables that make the life cycle of such a piece of water very expensive in addition to the use of filters in synthetic material that it must then be disposed of in a landfill.

Le but de la présente invention est de permettre grâce au procédé proposé la réalisation d'une pièce d'eau avec des constituants d'origine naturelle et ensuite un traitement naturel de l'eau qu'il contient.The object of the present invention is to allow, thanks to the proposed method, the production of a body of water with constituents of natural origin and then a natural treatment of the water that it contains.

Le procédé selon l' invention est maintenant décrit en détail suivant un mode de réalisation préférentiel, non limitatif, en regard des dessins annexés qui montrent :

  • figure 1 : une vue en perspective d'une pièce d'eau réalisée selon la présente invention,
  • figure 2 : une vue d'une section d'une pièce d'eau réalisée selon le procédé de l'invention, et
  • figure 3 : une vue schématique du système d'épuration de l'eau.
The method according to the invention is now described in detail according to a preferred embodiment, not limiting, with reference to the appended drawings which show:
  • figure 1 : a perspective view of a body of water made according to the present invention,
  • figure 2 : a view of a section of a body of water produced according to the method of the invention, and
  • figure 3 : a schematic view of the water purification system.

Le procédé de réalisation d'une pièce d'eau selon la présente invention consiste, dans une première étape, à creuser un bassin 10 avec un contour adapté pour obtenir la forme de la pièce d'eau à réaliser avec la profondeur souhaitée.The method of producing a water body according to the present invention consists, in a first step, in digging a basin 10 with a contour adapted to obtain the shape of the body of water to be produced with the desired depth.

On retrouve cet agencement en figure 1.We find this arrangement in figure 1 .

Ce bassin doit avoir de façon préférentielle sur toute sa périphérie une pente avec un ratio de 3 de long pour 1 de haut entre la plage 12 future laissée par l'eau arrivant à son seuil 13 de remplissage.This basin must have preferentially over its entire periphery a slope with a ratio of 3 long to 1 high between the future range 12 left by the water arriving at its threshold 13 of filling.

Cette pente, non nécessaire est néanmoins fortement préférentielle.This slope, which is not necessary, is nevertheless highly preferential.

En effet, la deuxième étape consiste à réaliser une couche 14 d'étanchéité à base d'argile compactée. On se réfère à la figure 2.Indeed, the second step consists in producing a sealing layer 14 based on compacted clay. We refer to the figure 2 .

Cette couche 14 d'étanchéité comprend de façon préférentielle deux couches 14-1 et 14-2 superposées et compactées individuellement. Le compactage est plus efficace sur deux couches d'une épaisseur e que un compactage unique sur une épaisseur 2e. On retient de façon adaptée mais non limitative une valeur de e de 20 cm.This sealing layer 14 preferably comprises two layers 14-1 and 14-2 superimposed and compacted individually. The compaction is more effective on two layers of a thickness e than a single compaction on a thickness 2e . A value of e of 20 cm is suitably but non-limitatively retained.

Selon le procédé de l'invention, le compactage est effectué avec au moins un cylindre à dents. Un tel cylindre permet d'exercer un effort important sur l'argile par les dents conduisant à un fort compactage.According to the process of the invention, compaction is carried out with at least one toothed cylinder. Such a cylinder makes it possible to exert a strong force on the clay by the teeth leading to a strong compaction.

L'argile elle-même est choisie dans les différentes variétés existantes mais son taux de siccité doit être adapté pour l'obtention du compactage optimal. Trop humide l'argile se compacte mal et laisse des vides conduisant à une plus faible étanchéité et trop sèche, l'adhésion entre les grains s'effectue mal également ce qui laisse aussi subsister des possibilités d'infiltration.The clay itself is chosen from the different existing varieties but its dryness rate must be adapted to obtain optimal compaction. Too wet the clay compacted poorly and left empty leading to a lower seal and too dry, the adhesion between the grains is also poor, which also leaves opportunities for infiltration.

L'argile une fois compactée au rouleau à dents est ensuite lissée dans une troisième étape afin de conférer au fond du bassin un état de surface régulier.The clay once compacted with a tooth roller is then smoothed in a third step to give the bottom of the basin a regular surface condition.

Une couche 16 de séparation est rapportée sur la surface de l'argile dans une quatrième étape. Cette couche est par exemple dans un mode de réalisation, un matériau de carrière, avantageusement de granulométrie 40/70 et la nature est du calcaire dans l'exemple retenu. Cette couche est faiblement compactée de sorte à la stabiliser sachant qu'elle coopère avec l'argile en surface qui assure son maintien en place. Il y a là une autre effet de synergie puisque l'argile reçoit à sa surface la couche de matériau de carrière et que la couche de matériau de carrière la protège mécaniquement et évite aux utilisateurs d'être en contact avec ce matériau qui, s'il assure une très bonne étanchéité n'est pas d'un contact agréable.A separation layer 16 is attached to the surface of the clay in a fourth step. This layer is for example in one embodiment, a quarry material, preferably of 40/70 particle size and the nature is limestone in the example selected. This layer is weakly compacted so as to stabilize it knowing that it cooperates with the clay surface that ensures its maintenance in place. This is another synergistic effect since the clay receives on its surface the layer of quarry material and the layer of quarry material protects it mechanically and prevents users from being in contact with this material, which it ensures a very good seal is not a pleasant touch.

Avantageusement là aussi, dans une cinquième étape, une couche 18 de sable est ensuite répartie sur cette couche 16 de matériau de calcaire. Cette couche 18 de finition, généralement du sable, qui par sa fine granulométrie est là aussi adaptée pour conférer une sensation agréable aux utilisateurs qui viendront au contact du fond. De plus, comme indiqué ci-après, cette couche 18 de finition en sable assure aussi un agrément à la vision donnant un fond clair, avec des capacités de développement de micro bactéries naturelles nécessaires au traitement de l'eau.Advantageously also, in a fifth step, a layer 18 of sand is then distributed over this layer 16 of limestone material. This layer 18 finish, usually sand, which by its fine particle size is also adapted to give a pleasant sensation to users who will come into contact with the bottom. In addition, as indicated below, this layer 18 of sand finish also provides an approval to the vision giving a clear background, with development capabilities of natural micro-bacteria needed for water treatment.

Les couches de calcaire et de sable tout comme la couche d'étanchéité peuvent se prolonger au delà de la zone mouillée pour constituer des plages autour de la pièce d'eau en fonction de la topographie des lieux et des souhaits des utilisateurs à venir.The layers of limestone and sand as well as the sealing layer can extend beyond the wet zone to form beaches around the water feature depending on the topography of the place and the wishes of future users.

Dans ce cas, la pente peut être éventuellement avec un ratio plus faible jusqu'à 4 de long pour 1 de haut.In this case, the slope may be possibly with a lower ratio up to 4 long for 1 high.

Le bassin réalisé selon le procédé peut être mis en eau, soit à partir d'un ru existant soit à partir d'une prise d'eau issue du sous-sol, soit encore au fur et à mesure des précipitations naturelles mais il faut prévoir une réalisation en période de pluie pour éviter le dessèchement de l'argile durant cette période de remplissage.The basin built according to the process can be put in water, either from an existing ru or from a water intake coming from the basement, or again as and when the natural precipitations but it is necessary to envisage a realization in rainy period to avoid the dryness of the clay during this period of filling.

Le procédé prévoit également des moyens de traitement de l'eau, MTE, comme montré sur la figure 3. Ce procédé permet d'obtenir une eau parfaitement claire quelle que soit la période de l'année. Le traitement de l'eau consiste en la succession suivante des étapes :

  • prélèvement par des moyens 20 de captage par débordement d'un volume d'eau, régulier,
  • passage gravitaire dans un filtre 22 à sable, et
  • remontage de l'eau épurée par des moyens 24 de pompage, et
  • distribution de cette eau épurée dans la pièce d'eau par écoulement oxygénant.
The method also provides water treatment means, MTE, as shown on the figure 3 . This process makes it possible to obtain perfectly clear water whatever the time of the year. Water treatment consists of the following sequence of steps:
  • sampling by means 20 of catching by overflow of a volume of water, regular,
  • gravitational passage in a sand filter 22, and
  • winding purified water by pumping means 24, and
  • distribution of this purified water in the body of water by oxygenating flow.

De façon avantageuse, il est prévu un dégrillage au débordement de sorte à retenir les corps étrangers flottants de grandes dimensions comme les feuilles et branches.Advantageously, an overflow screening is provided so as to retain the floating foreign bodies of large dimensions such as leaves and branches.

L'invention couvre aussi un procédé de réalisation d'un filtre 22 à sable.The invention also covers a method of producing a sand filter 22.

En effet, le filtre comprend une excavation 26, généralement de forme parallélépipédique, une entrée 28 d'eau prélevée, un réseau 30 de répartition, une couche 32 filtrante, un réseau 34 de collecte de l'eau épurée et un poste 36 de relevage.In fact, the filter comprises an excavation 26, generally of parallelepipedal shape, an intake 28 of withdrawn water, a distribution network 30, a filtering layer 32, a network 34 for collecting purified water and a station 36 for lifting. .

Selon un mode préférentiel de l'invention, l'excavation 26, une fois creusée est aussi recouverte sur son fond et sur ses parois d'une couche d'argile afin d'assurer une étanchéité des parois. Les pressions exercées et la quantité d'eau traversante ne requièrent pas un compactage du type de celui du bassin et une simple enduction au moyen d'une pelle mécanique suffit.According to a preferred embodiment of the invention, the excavation 26, once dug is also covered on its bottom and on its walls with a layer of clay to ensure a tightness of the walls. The pressures exerted and the amount of water passing through do not require a compaction of the basin type and a simple coating by means of a mechanical shovel is sufficient.

Les réseaux 30 de répartition et 34 de collecte comportent de façon connue des tubes 38 en matériau plastique munis de fentes formant drain.The distribution and collection networks 30 comprise, in known manner, tubes 38 of plastics material provided with drain slots.

Des géotextiles 40 peuvent isoler les différentes zones, ceci toujours de façon connue.Geotextiles 40 can isolate the different zones, this always in a known manner.

L'entrée du réseau de répartition est équipée de moyens 42 de contrôle du débit d'eau recueilli à débordement, pour ajuster le débit d'eau à épurer.The inlet of the distribution network is equipped with means 42 for controlling the flow of water collected overflow, to adjust the flow of water to be purified.

Le poste 36 de relevage comprend un regard 44 avec des moyens 24 de pompage. Ces moyens 24 de pompage sont soit des pompes électriques, soit des moyens mus par des énergies renouvelables tels que des pompes éoliennes.The lifting station 36 includes a view 44 with means 24 for pumping. These pumping means 24 are either electric pumps or means driven by renewable energies such as wind pumps.

L'eau refoulée est réintroduite dans la pièce d'eau par tout moyen 46 d'oxygénation adapté. On peut ainsi citer une cascade, ou un écoulement irrégulier sur un lit de galets de dimensions aptes à générer des multitudes de petits seuils assurant ainsi une oxygénation de l'eau qui prend le caractère d'eau vive et non d'eau stagnante.The discharged water is reintroduced into the body of water by any adapted oxygenation means 46. One can thus quote a cascade, or an irregular flow on a bed of rollers of dimensions able to generate multitudes of small thresholds thus ensuring an oxygenation of the water which takes the character of living water and not stagnant water.

Ce regard comprend aussi une sortie de vidange en point bas pour assurer la vidange de la pièce d'eau si besoin est vers une dépression naturelle perméable ou vers le réseau d'assainissement d'eaux pluviales lorsqu'il existe.This view also includes a drain outlet at low point to ensure the emptying of the water body if necessary towards a natural permeate depression or to the stormwater network where it exists.

De façon avantageuse, il est prévu une prise 48 de fond avec grille, disposée en point bas du bassin afin de permettre une vidange totale du bassin si besoin était.Advantageously, there is provided a background intake 48 with a grid, disposed at the bottom of the basin to allow a complete emptying of the basin if needed.

Les divers circuits sont prévus au moment du modelage de sorte à ce qu'ils soient intégrés dans le sol.The various circuits are provided at the time of modeling so that they are integrated in the ground.

Ainsi la pièce d'eau réalisée selon le procédé est très faiblement perméable au point de la considérer comme étanche, nécessitant des apports d'eau plus pour compenser l'eau perdue par évaporation que l'eau perdue par pénétration dans le sol à travers la couche d'argile.Thus the piece of water produced by the process is very weakly permeable to the point of considering it as watertight, requiring more water inputs to compensate for the water lost by evaporation than the water lost by penetration into the soil through the clay layer.

Quant à l'eau, elle est traitée en permanence par filtration sur lit de sable, les impuretés retenues étant digérées par des bactéries à ensemencement naturel. Cette eau est également oxygénée si bien qu'elle est de très bonne qualité et se trouve devenir très claire déjà après quelques jours de mise en eau seulement. L'entretien d'une telle installation est extrêmement limité puisque son fonctionnement est naturel, sans apport chimique et sans apport de chaleur ou de froid. La consommation reste limitée au seul relevage de l'eau qui de plus peut être réalisé au moyen d'une énergie renouvelable dont on sait que l'investissement de départ peut être un peu plus élevé mais dont le coût de fonctionnement est nul.As for the water, it is permanently treated by filtration on a bed of sand, the impurities retained being digested by bacteria with natural seeding. This water is also oxygenated so that it is of very good quality and is becoming very clear already after a few days of impoundment only. The maintenance of such an installation is extremely limited since its operation is natural, without chemical input and without heat or cold input. Consumption remains limited to the only lifting of the water which moreover can be realized by means of a renewable energy which one knows that the initial investment may be a little higher but the operating cost is nil.

Selon une variante de réalisation, le procédé prévoit de réaliser la couche 16 de séparation non pas avec du calcaire mais avec un film du type polyane étanche. Néanmoins, comme ce film est déposé en bandes partiellement superposées, il n'assure pas l'étanchéité puisque les bandes ne sont pas soudées et c'est toujours l'argile qui remplit cette fonction.According to an alternative embodiment, the method provides for making the separation layer 16 not with limestone but with a tight polyane type film. However, since this film is deposited in partially superimposed strips, it does not seal because the strips are not welded and it is still the clay that fulfills this function.

Le polyane évite par contre tout passage des particules d'argile.On the other hand, the polyane prevents any passage of the clay particles.

Afin de protéger ce film polyane qui est relativement fragile mécaniquement et notamment au poinçonnement, il est prévu que cette couche 16 de séparation soit renforcée par un géotextile anti-poinçonnement de 250g par exemple.In order to protect this polyane film which is relatively mechanically fragile and in particular punching, it is expected that this separation layer 16 is reinforced by an anti-punching geotextile of 250g for example.

Ainsi, le géotextile peut recevoir la couche 18 de finition, notamment du sable. Cet agencement évite de façon particulièrement satisfaisante les remontées d'argile colorée dans la couche de finition, surtout quand elle est réalisée en sable clair.Thus, the geotextile can receive the finishing layer 18, in particular sand. This arrangement particularly satisfies the return of colored clay in the topcoat, especially when it is made of clear sand.
