Description

La présente invention concerne un abri léger pour le stockage et la conservation dans un environnement confiné de produits organiques biodégradables, tels que les grumes et/ou bois sciés, les produits pulvérulents, en particulier les farines animales, ainsi qu'un procédé, en particulier pour la mise en oeuvre d'un tel abri léger.The present invention relates to a light shelter for storage and conservation in a confined environment biodegradable organic products, such as logs and / or sawn wood, pulverulent products, in particular animal meal, as well as a process, in particular for the implementation of such a light shelter.

La conservation sur une longue période, généralement de deux à quatre ans, de grumes et/ou de bois sciés nécessite d'inhiber au cours de cette période le développement et la croissance des organismes susceptibles d'attaquer le bois stocké.Long term storage, usually of two to four years, logs and / or sawn timber requires to inhibit during this period the development and growth of organisms likely to attack wood stored.

Deux méthodes sont utilisées à ce jour.Two methods are used to date.

La première méthode, dite par voie humide, consiste à immerger les grumes dans l'eau ou à soumettre les grumes à une aspersion continue de façon à garantir en permanence un degré d'hygrométrie égal ou supérieur à 100 % dans le bois. De cette manière, le développement des champignons et des insectes est rendu impossible et les bois stockés sont conservés dans de bonnes conditions. Toutefois, ce procédé par voie humide présente un certain nombre d'inconvénients. Il nécessite en particulier un réseau de pompage et de pressurisation et engendre une consommation en eau et en énergie élevée. Par ailleurs, l'eau d'aspersion chargée en éléments présente des risques pour l'environnement. Il est donc nécessaire de retraiter cette eau. Enfin, les bois ainsi conservés doivent subir un séchage avant transformation. Les inconvénients précités rendraient le procédé particulièrement onéreux.The first method, called the wet method, consists in immerse the logs in water or subject the logs to continuous spraying so as to permanently guarantee a humidity level 100% or more in wood. In this way, the development of fungi and insects is made impossible and stored wood is kept in good condition. However, this process wet has a number of disadvantages. In particular, it requires a pumping and pressurization and generates a consumption of water and high energy. In addition, the spray water loaded with elements present risks to the environment. It is therefore necessary to reprocess this water. Finally, the woods thus preserved must be dried before transformation. The aforementioned drawbacks would make the particularly expensive process.

La seconde méthode, dite par voie sèche, consiste à stocker les grumes en les revêtant d'un élément de couverture de type bâche. La composition de l'atmosphère ainsi confinée sous l'élément de couverture évolue rapidement par suite des réactions des espèces stockées et se traduit par une consommation de l'oxygène présent et la formation de gaz carbonique. Le milieu anaérobie ainsi créé limite le développement d'espèces destructrices. Tel est le cas des procédés décrits dans la demande de brevet internationale WO 98/26907 et le brevet US-A-2.617.202. Cette deuxième méthode est toutefois demeurée au stade expérimental en raison des difficultés de mise en oeuvre. En effet, la manipulation d'un élément de couverture de grande dimension a jusqu'à présent empêché son utilisation à des fins industrielles. Par ailleurs, les éléments de couverture utilisés jusqu'à présent présentaient une fiabilité insuffisante, nécessitant une maintenance importante au niveau du contrôle de l'atmosphère sous l'élément de couverture, en raison notamment de risques importants de rupture de l'élément de couverture. Dans d'autres cas, tels que ceux décrits dans les brevets FR-A-2.696.230 et US-A-5.579.820, la construction des abris est trop complexe pour permettre une exploitation industrielle de ces derniers.The second method, known as the dry method, consists in storing the logs by covering them with a covering element of tarpaulin type. The composition of the atmosphere thus confined under the cover element changes rapidly as a result reactions of the stored species and results in a consumption of oxygen present and gas formation carbonic. The anaerobic environment thus created limits the development of destructive species. This is the case with processes described in the international patent application WO 98/26907 and US-A-2,617,202. This second method, however, remained at the experimental stage in because of the difficulties of implementation. Indeed, the handling a large roofing element has so far prevented its use for any purpose industrial. In addition, the hedging elements used so far had reliability insufficient, requiring significant maintenance at level of atmospheric control under the element of coverage, in particular due to significant risks of rupture of the cover element. In other cases, such than those described in patents FR-A-2,696,230 and US-A-5,579,820, shelter construction is too complex for allow industrial exploitation of these.

Parallèlement aux grumes et/ou bois sciés, d'autres produits biodégradables posent des problèmes de stockage. Tel est le cas des produits pulvérulents, en particulier des farines animales stockées en vrac ou à l'état conditionné. Les enceintes de stockage de ces farines sont aujourd'hui constituées par des hangars à parois généralement en tôle qui ne permettent pas, de par leur conception, d'assurer un stockage étanche à l'environnement des produits et qui se révèlent onéreux en termes de coût d'exploitation dans le temps.In addition to logs and / or sawn timber, other biodegradable products pose storage problems. This is the case with powdery products, in particular animal meal stored in bulk or as is conditioned. The storage enclosures of these flours are today made up of walled hangars generally made of sheet metal which, due to their design, ensure environmentally tight storage of products and which prove to be expensive in terms of cost operating over time.

Un premier but de la présente invention est de proposer un abri léger dont la conception permet une pose aisée et rapide.A first object of the present invention is to provide a light shelter whose design allows easy installation and fast.

Un autre but de la présente invention est de proposer un abri léger dont la conception permet de réduire la maintenance.Another object of the present invention is to provide a lightweight shelter whose design reduces the maintenance.

A cet effet, l'invention a pour objet un abri léger pour le stockage et la conservation dans un environnement confiné de produits organiques biodégradables, tels que les grumes et/ou bois sciés, les produits pulvérulents, en particulier les farines animales, caractérisé en ce qu'il est constitué d'au moins un élément de couverture préfabriqué obtenu par assemblage, généralement par soudure, de lés réalisés en un matériau synthétique souple étanche à l'eau et à l'air, cet assemblage de lés délimitant une âme rectangulaire ou carrée formant toit prolongée d'une part, latéralement, de deux ailes trapézoïdales reliées chacune à l'âme par leur petite base, d'autre part, axialement, de rabats généralement rectangulaires ou carrés dont les bords libres de deux côtés parallèles sont respectivement solidarisés à un côté de l'aile trapézoïdale pour délimiter une chambre parallélépipédique de section transversale trapézoïdale dite principale dont les parois viennent à l'état dressé de l'élément de couverture coiffer l'empilement de forme générale parallélépipédique à section transversale trapézoïdale de produits organiques biodégradables.To this end, the invention relates to a light shelter for the storage and conservation in a confined environment biodegradable organic products, such as logs and / or sawn wood, pulverulent products, in particular animal meal, characterized in that it is made up at least one prefabricated roofing element obtained by assembly, generally by welding, of strips made in one flexible waterproof and airtight synthetic material, this assembly of strips delimiting a rectangular core or square forming an extended roof on the one hand, laterally, two trapezoidal wings each connected to the core by their small base, on the other hand, axially, of flaps generally rectangular or square with free edges of two parallel sides are respectively secured to one side of the trapezoidal wing to delimit a room trapezoidal cross section parallelepiped said main whose walls come in the erect state of the cover element cover the stack of form general parallelepiped with cross section trapezoidal of biodegradable organic products.

La conception de l'élément de couverture de forme prédéterminée permet, après fabrication, de plier l'élément en identifiant la position de chaque partie de cet élément. Ainsi, au moment de sa pose sur site, l'élément de couverture est posé à l'état plié en un emplacement déterminé sur le sommet de l'empilement de produits organiques biodégradables à conserver puis déplié manuellement pour venir, au moyen des parois de l'élément de couverture, coiffer l'empilement de produits. Dans le cas de grumes, l'élément de couverture peut ainsi recouvrir un volume de l'ordre de 200 m3 correspondant à un empilement de grumes de 18 mètres de longueur et 8 mètres de largeur en utilisant simplement un engin de levage pour positionner l'élément de couverture à l'état plié au sommet de l'empilement de grumes. La pose d'un tel élément de couverture devient ainsi particulièrement aisée. Il en est de même dans le cas de farines animales conditionnées dans des conteneurs souples de grande contenance dits "big-bag" puis empilées pour former l'empilement de forme générale -parallélépipédique à section transversale trapézoïdale.The design of the form cover element predetermined allows, after manufacture, to bend the element by identifying the position of each part of this element. Thus, at the time of its installation on site, the element of cover is laid folded in one place determined on the top of the product stack biodegradable organic to keep then unfolded manually to come, by means of the walls of the element cover, style the stack of products. In the in the case of logs, the covering element can thus cover a volume of around 200 m3 corresponding to a stack of logs 18 meters long and 8 meters in width by simply using a hoist to position the cover element in the folded state at the top from the stack of logs. The installation of such an element of coverage becomes particularly easy. It is similarly in the case of animal meal packaged in flexible containers of large capacity called "big-bag" then stacked to form the generally shaped stack -parallelepipedic with trapezoidal cross section.

L'invention a encore pour objet un procédé pour le stockage et la conservation dans un environnement confiné de produits organiques biodégradables, tels que les grumes et/ou bois sciés, les produits pulvérulents, en particulier les farines animales, en particulier au moyen d'un abri léger, caractérisé en ce qu'on recouvre successivement l'aire de stockage d'au moins une couche d'un matériau absorbant les chocs et les différences de relief et d'un tapis de sol de l'abri léger, en ce qu'on dispose sur le tapis de sol des supports, tels que des bastaings servant à la réception des de produits organiques à conserver, en ce qu'on empile les produits organiques à conserver sur les supports de manière à former un empilement de forme générale parallélépipédique à section transversale trapézoïdale, en ce qu'on recouvre l'empilement de produits organiques à conserver d'une couche d'un matériau absorbant les chocs et les différences de relief, en ce qu'on coiffe l'empilement d'un élément de couverture préfabriqué prépositionné à l'état plié au sommet de l'empilement de produits organiques à conserver, en ce qu'on solidarise de manière étanche l'élément de couverture préfabriqué et le tapis de sol pour former une enceinte fermée de forme parallélépipédique à section transversale trapézoïdale.The invention also relates to a method for storage and conservation in a confined environment of biodegradable organic products, such as logs and / or sawn wood, pulverulent products, in particular animal meal, in particular by means of a shelter light, characterized in that successively covers the storage area of at least one layer of a material absorbing shocks and differences in relief and a light shelter floor mat, as available on the support floor mats, such as bastaings used to the receipt of organic products to be stored, that the organic products to be stored are stacked on supports so as to form a stack of shapes general parallelepiped with cross section trapezoidal, in that it covers the stack of products organic to keep a layer of absorbent material the shocks and the differences in relief, in that we style stacking a prefabricated roofing element prepositioned in the folded state at the top of the stack of organic products to be preserved, in that tightly the prefabricated roofing element and the floor mat to form a closed enclosure rectangular with trapezoidal cross section.

These strips are preferably assembled by weld their longitudinal edges, as shown in the figure 1. This assembly of strips delimits, after removal parts corresponding to the hatched parts in the Figure 1, a rectangular or square core 5 forming a roof extended on the one hand, laterally, by two wings 6 trapezoidal each connected to the core 5 by their small base, on the other hand, axially, of flaps 7 generally rectangular or square with free edges 7A of two parallel sides are respectively secured to one side 6A of the trapezoidal wing.

    A l'état solidarisé, l'ensemble délimite une chambre parallélépipédique de section transversale trapézoïdale. Les parois de cette chambre viennent, à l'état dressé de l'élément 2 de couverture, coiffer l'empilement parallélépipédique à section transversale trapézoïdale de grumes 15 et/ou de bois sciés à conserver.In the joined state, the whole delimits a room rectangular trapezoidal cross section. The walls of this chamber come, in the erect state of cover element 2, cover the stack rectangular trapezoidal cross section of 15 logs and / or sawn timber to keep.

    Outre cet élément 2 de couverture préfabriqué, l'abri léger comporte au moins un tapis 3 de sol destiné à recevoir l'empilement de grumes 15 ou de bois sciés à conserver. Ce tapis 3 de sol est, de la même manière que l'élément 2 de couverture, réalisé en un matériau synthétique souple étanche à l'eau et à l'air. Ce tapis de sol 3 est par ailleurs assemblable de manière étanche à l'élément 2 de couverture pour former une enceinte étanche à l'eau et à l'air. De préférence, l'élément 2 de couverture préfabriqué et le tapis 3 de sol sont réalisés en PVC de manière à fournir à l'abri léger une aptitude à la déformation suffisante pour permettre, en particulier lors du raccordement de l'élément 2 de couverture à une source d'aspiration d'air, le plaquage des parois de la chambre délimitée par l'élément 2 de couverture contre l'empilement de grumes 15 de manière à réduire rapidement la quantité d'air contenue à l'intérieur de ladite chambre pour limiter les phénomènes d'oxydation. L'élément 2 de couverture préfabriqué peut également être traité anti-UV.In addition to this prefabricated cover element 2, the light shelter comprises at least one floor mat 3 intended to receive stacking 15 logs or sawn timber to keep. This floor mat 3 is, in the same way as item 2 of cover, made of a flexible synthetic material waterproof and airtight. This floor mat 3 is by elsewhere sealable to element 2 of cover to form a watertight and the air. Preferably, the prefabricated cover element 2 and the floor mat 3 are made of PVC so as to provide the light shelter with a capacity for deformation sufficient to allow, especially when connection of the cover element 2 to a source air intake, plating the chamber walls delimited by cover element 2 against stacking of logs 15 so as to quickly reduce the amount of air contained inside said chamber to limit oxidation phenomena. Cover element 2 prefab can also be UV treated.

    Comme le montre la figure 2, les ailes 6 et les rabats 7 de l'élément 2 de couverture comportent chacun dans leur prolongement une bavette 8 en appui au sol à l'état dressé de l'élément 2 de couverture. Cet élément 2 de couverture peut ainsi être assimilé à un double toit. Le tapis 3 de sol présente quant à lui une surface supérieure à la surface de l'aire délimitée par les bavettes 8 de l'élément de couverture pour permettre un repli à recouvrement des bords de tapis sur les bavettes 8 et leur solidarisation à ces dernières par une liaison étanche, comme le montrent les flèches de la figure 3. Cette solidarisation est généralement réalisée par soudure. Cette configuration permet de réutiliser l'élément 2 de couverture. Ainsi, lorsque l'abri léger doit être ouvert, l'élément 2 de couverture et le tapis sont découpés au niveau de la liaison bavette-tapis. Les bavettes 8 de l'élément 2 de couverture ayant été surdimensionnées, l'élément 2 de couverture peut être réutilisé avec un nouveau tapis de sol.As shown in Figure 2, the wings 6 and the flaps 7 of cover element 2 each have in their extension of a flap 8 resting on the ground in the upright state of cover element 2. This cover element 2 can thus be compared to a double roof. The carpet 3 of soil has an area greater than the surface of the area delimited by the flaps 8 of the element of cover to allow a fold to overlap of the carpet edges on the flaps 8 and their attachment to these by a tight connection, as shown the arrows in Figure 3. This connection is generally made by welding. This configuration allows reuse of the cover element 2. So, when the light shelter is to be opened, element 2 of blanket and carpet are cut at the flap-carpet connection. The flaps 8 of element 2 of cover having been oversized, element 2 of cover can be reused with a new mat ground.

    Cet abri léger comporte généralement, en outre, un second élément 4 de couverture agencé pour s'interposer entre l'élément 2 de couverture préfabriqué et les grumes 15 à stocker à l'état dressé de l'élément 2 de couverture préfabriqué. Ce second élément 4 de couverture est constitué d'un matériau absorbant les chocs et les différences de relief. A titre d'exemple, ce second élément 4 de couverture peut être constitué par un géotextile. La présence de ce second élément 4 de couverture permet, lors du plaquage des parois du premier élément 2 de couverture préfabriqué contre les grumes 15, d'éviter toute rupture de ce premier élément 2 de couverture de manière à garantir l'étanchéité de l'enceinte délimitée par l'élément 2 de couverture préfabriqué.This light shelter generally also includes a second cover element 4 arranged to be interposed between prefabricated roofing element 2 and logs 15 to store in upright condition of cover element 2 prefabricated. This second cover element 4 is made of shock absorbing material and relief differences. As an example, this second element 4 of cover can be constituted by a geotextile. The presence of this second cover element 4 allows, during plating the walls of the first cover element 2 prefabricated against logs 15, to avoid any breakage of this first element 2 of cover so as to guarantee the tightness of the enclosure delimited by element 2 of prefabricated cover.

    L'élément 2 de couverture préfabriqué est muni d'au moins deux orifices 9A, 9C obturables raccordables à un conduit 10 de circulation de fluide externe audit élément 2 de couverture pour établir un circuit fermé de circulation de fluide entre la chambre principale délimitée par l'élément 2 de couverture et le conduit de circulation de fluide. Un tel conduit de circulation de fluide est plus particulièrement représenté à la figure 6. Ce conduit 10 externe de circulation de fluide comporte sur son circuit au moins une enceinte étanche dite chambre 11 auxiliaire renfermant au moins une grume témoin. Cette enceinte étanche peut être fabriquée à partir des chutes de l'élément 2 préfabriqué. Cette enceinte étanche est déconnectable du conduit 10 externe après isolement de ce conduit 10 de l'atmosphère de la chambre délimitée par l'élément 2 de couverture. Il est ainsi possible d'étudier une grume témoin pour en déduire l'évolution des grumes contenues sous l'élément 2 de couverture préfabriquée. Cette opération peut être répétée plusieurs fois dans le temps en disposant plusieurs chambres 11 auxiliaires en série, comme le montre la figure 6, et en déconnectant dans le temps successivement lesdites chambres auxiliaires.The prefabricated cover element 2 is provided with at least two closable openings 9A, 9C connectable to a conduit 10 for circulation of fluid external to said element 2 of cover to establish a closed circulation circuit of fluid between the main chamber delimited by the element 2 cover and the fluid circulation duct. A such fluid circulation duct is more particularly shown in Figure 6. This conduit 10 external fluid circulation has on its circuit at least one sealed enclosure called auxiliary chamber 11 containing at least one witness log. This enclosure waterproof can be made from scrap element 2 prefabricated. This waterproof enclosure is disconnectable from the external conduit 10 after isolation of this duct 10 of the atmosphere of the room delimited by cover element 2. It is thus possible to study a witness log to deduce the evolution of the logs contained under element 2 of prefabricated cover. This can be repeated several times in the time by having several auxiliary chambers 11 in series, as shown in Figure 6, and by disconnecting in successively said auxiliary chambers.

    Ce conduit 10 externe de circulation de fluide peut encore comporter sur son circuit au moins un piège 12 à CO2. Ce pièce 12 à CO2 peut être constitué simplement d'un récipient renfermant de la chaux. En effet, des expériences ont démontré que, au cours du stockage, l'atmosphère sous l'élément 2 de couverture préfabriquée, évolue. This external fluid circulation conduit 10 may also include on its circuit at least one CO 2 trap 12. This CO 2 part 12 can simply consist of a container containing lime. In fact, experiments have shown that, during storage, the atmosphere under the prefabricated cover element 2 changes.

    L'atmosphère fortement chargée en oxygène et en CO2 tend, au cours du temps, à être essentiellement chargée de CO2 et d'azote, l'oxygène ayant été consommé. Toutefois, il s'avère que, dans une atmosphère anaérobie fortement chargée en CO2, certaines espèces microbiennes arrivent encore à se développer. L'objectif est donc de réduire également la quantité de CO2 contenue dans l'enceinte au profit de l'azote. La présence de ce piège 12 à CO2 permet une telle élimination. La disposition de ce piège 12 à CO2 à l'extérieur de l'élément 2 de couverture permet de recharger de temps en temps ce piège 12 à CO2 ou de le remplacer par un nouveau piège 12 à CO2.The atmosphere highly charged with oxygen and CO 2 tends, over time, to be essentially charged with CO 2 and nitrogen, the oxygen having been consumed. However, it turns out that, in an anaerobic atmosphere highly charged with CO 2 , certain microbial species still manage to develop. The objective is therefore to also reduce the quantity of CO 2 contained in the enclosure in favor of nitrogen. The presence of this CO 2 trap 12 allows such elimination. The arrangement of this CO 2 trap 12 outside the cover element 2 makes it possible to recharge this CO 2 trap 12 from time to time or to replace it with a new CO 2 trap 12.

    Pour que la conduite 10 externe de circulation de fluide transporte un air correspondant effectivement à l'ensemble de l'air contenu dans l'atmosphère de l'élément 2 de couverture, au moins l'un 9A des orifices 9A, 9C obturables de l'élément 2 de couverture est en outre raccordable à un conduit 18 de circulation de fluide interne s'étendant à l'intérieur de la chambre principale délimitée par l'élément 2 de couverture, comme le montre la figure 4. Ce conduit 18 de circulation de fluide interne permet ainsi de prélever de l'air au voisinage d'une des parois de l'enveloppe opposée à la paroi comportant les orifices obturables.So that the external fluid circulation line 10 conveys air that actually matches the whole of air contained in the atmosphere of element 2 of cover, at least one 9A of closable openings 9A, 9C of the cover element 2 is also connectable to a internal fluid circulation conduit 18 extending to the interior of the master bedroom bounded by cover element 2, as shown in figure 4. This conduit 18 of internal fluid circulation thus allows take air in the vicinity of one of the walls of the envelope opposite the wall comprising the orifices closable.

    L'élément 2 de couverture est en outre de préférence muni d'au moins un troisième orifice 9B obturable raccordable à un drain 13 s'étendant à l'intérieur de la chambre principale délimitée par l'élément 2 de couverture. L'orifice 9C de l'élément 2 de couverture est quant à lui utilisé au départ pour pouvoir être raccordé à une source d'aspiration d'air externe audit élément 2 de couverture, de manière à venir plaquer les parois de l'élément 2 de couverture contre les grumes 15 à stocker.The cover element 2 is also preferably provided at least a third closable orifice 9B connectable to a drain 13 extending inside the chamber main delimited by cover element 2. The opening 9C of the cover element 2 is used initially to be able to be connected to a source suction of air external to said cover element 2, so as to press the walls of element 2 of log cover 15 to store.

    L'ensemble de ces orifices 9A à 9C obturables est porté par une platine rapportée sur l'élément 2 de couverture. Chaque orifice obturable peut être conçu de manière analogue à ce qui est représenté à la figure 5. Dans ce cas, chaque orifice comporte un passe paroi représenté en 21 aux figures pour permettre un raccordement interne ou externe, une vanne d'arrêt 19 pour isoler l'élément 2 de couverture de l'extérieur et un obturateur automatique 20 disposé en série avec la vanne d'arrêt et sur le côté externe de cette dernière. Cet obturateur automatique permet de venir automatiquement raccorder le circuit externe de circulation de fluide.All of these closable orifices 9A to 9C are carried by a plate attached to the cover element 2. Each closable orifice can be designed analogously to this which is shown in Figure 5. In this case, each orifice has a wall pass shown at 21 aux figures to allow internal or external connection, a stop valve 19 for isolating the cover element 2 from the outside and an automatic shutter 20 arranged in series with the shut-off valve and on the outer side of this last. This automatic shutter allows you to come automatically connect the external circulation circuit of fluid.

    Pour permettre le stockage et la conservation de grumes 15 au moyen d'un tel abri, on pratique de la manière suivante. On recouvre successivement l'aire de stockage d'au moins une couche 17 d'un matériau absorbant les chocs et les différences de relief et d'un tapis 3 de sol de l'abri léger. On dispose ensuite sur le tapis 3 de sol des supports 16, tels que des bastaings, servant à la réception des grumes 15. Ces supports 16 ont en outre l'avantage de créer une lame d'air entre les grumes 15 et le tapis de sol de manière à mieux isoler ces derniers. On empile les grumes 15 sur les supports 16 de manière à former un empilement parallélépipédique à section transversale trapézoïdale puis on recouvre l'empilement de grumes 15 d'une couche 4 d'un matériau absorbant les chocs et les différences de relief. Cette couche 4 de matériau constitue le second élément de couverture interposé entre l'élément de couverture préfabriqué et les grumes. La précision de pose de cette couche 4 de matériau absorbant n'étant pas nécessaire, cette couche 4 de matériau absorbant peut se présenter sous forme d'une simple couche venant à recouvrement sur les grumes 15 stockées. On coiffe ensuite l'empilement de grumes d'un élément 2 de couverture préfabriqué du type précité après avoir préalablement positionné ce dernier à l'état plié au sommet de l'empilement de grumes, puis on solidarise de manière étanche l'élément 2 de couverture préfabriqué et le tapis 3 de sol pour former une enceinte fermée de forme parallélépipédique à section transversale trapézoïdale. On connecte alors l'élément 2 de couverture préfabriqué à une source de dépression ou d'aspiration d'air pour appliquer les parois de l'élément 2 de couverture contre l'empilement de grumes 15 de manière à réduire la quantité d'air à l'intérieur de ladite enceinte. On connecte ensuite l'élément 2 de couverture préfabriqué à un piège 12 à CO2 et/ou à une chambre 11 auxiliaire renfermant une grume témoin. Les grumes peuvent alors être conservées dans une telle enceinte pendant plusieurs années. De temps en temps, une grume témoin disposée dans une chambre auxiliaire peut être prélevée pour permettre un suivi de l'évolution des grumes sous l'élément 2 de couverture. Le piège à CO2 peut également être remplacé de temps en temps en fonction de la composition de l'atmosphère sous l'élément 2 de couverture préfabriqué. Au moment du déstockage des grumes 15, l'élément 2 de couverture préfabriqué est désolidarisé du tapis 3 de sol par découpage des bavettes le long de la ligne de soudure. L'élément 2 de couverture peut ainsi être réutilisé pour un nouveau stockage, les bavettes ayant été surdimensionnées à cet effet.To allow the storage and preservation of logs 15 by means of such a shelter, it is practiced as follows. The storage area is successively covered with at least one layer 17 of a material which absorbs shocks and differences in relief and a carpet 3 of ground for the light shelter. Then there are on the floor mat 3 supports 16, such as bastaings, used for receiving logs 15. These supports 16 also have the advantage of creating an air space between the logs 15 and the carpet. ground so as to better isolate them. The logs 15 are stacked on the supports 16 so as to form a parallelepipedal stack with a trapezoidal cross section, then the stack of logs 15 is covered with a layer 4 of a material absorbing shock and differences in relief. This layer 4 of material constitutes the second covering element interposed between the prefabricated covering element and the logs. Since the precision of laying this layer 4 of absorbent material is not necessary, this layer 4 of absorbent material can be in the form of a single layer overlapping the stored logs. The stack of logs is then capped with a prefabricated covering element 2 of the aforementioned type after having previously positioned the latter in the folded state at the top of the stack of logs, then the element 2 of prefabricated cover and the floor mat 3 to form a closed enclosure of parallelepiped shape with trapezoidal cross section. The prefabricated cover element 2 is then connected to a source of vacuum or air suction in order to apply the walls of the cover element 2 against the stack of logs 15 so as to reduce the amount of air to inside said enclosure. The prefabricated cover element 2 is then connected to a CO 2 trap 12 and / or to an auxiliary chamber 11 containing a control log. The logs can then be stored in such an enclosure for several years. From time to time, a witness log placed in an auxiliary chamber can be removed to allow monitoring of the progress of the logs under the cover element 2. The CO 2 trap can also be replaced from time to time depending on the composition of the atmosphere under the prefabricated cover element 2. When the logs 15 are removed from storage, the prefabricated cover element 2 is detached from the floor mat 3 by cutting flaps along the weld line. The cover element 2 can thus be reused for new storage, the flaps having been oversized for this purpose.

    Dans un autre mode de réalisation de l'invention conforme à la figure 7, le tapis de sol représenté en 3' affecte une forme similaire à celle de l'élément 2 de couverture préfabriqué. Le tapis de sol 3' est alors logé dans un canal de section trapézoïdale obtenu par terrassement. Les côtés remblayés et compactés du canal constituent d'une part une assise pour la pose de bastaings latéraux, d'autre part une plate-forme d'accès aux engins de manutention. On obtient ainsi un abri léger semi-enterré constitué de deux éléments 2 de couverture préfabriqués positionnés en vis à vis avec l'un des éléments 2 de couverture faisant office de tapis de sol. A l'état assemblé des éléments constitutifs de l'abri, on obtient une cellule hexagonale formée par la superposition de deux chambres trapézoïdales communiquant entre elles. Cette cellule peut être compartimentée transversalement par des cloisons étanches. In another embodiment of the invention according to Figure 7, the floor carpet shown in 3 'affects a shape similar to that of cover element 2 prefabricated. The 3 'floor mat is then housed in a trapezoidal section channel obtained by earthworks. The backfilled and compacted sides of the canal constitute a part of a seat for the installation of lateral bastaings, other share a platform for access to handling equipment. We thus obtains a light semi-buried shelter made up of two prefabricated cover elements 2 positioned opposite screw with one of the cover elements 2 serving of floor mats. In the assembled state of the elements of the shelter, we get a hexagonal cell formed by the superposition of two trapezoidal chambers communicating with each other. This cell can be transversely compartmentalized by watertight bulkheads.

    Ce mode de réalisation permet également d'envisager un fonctionnement par aspersion en équipant la structure de buses d'arrosage fixés par exemple sur les bastaings latéraux. La présence de l'élément 2 de couverture préfabriqué étanche supprime l'évaporation et permet de coupler le mode anaérobie avec le mode sous hygrométrie maximale de 100 %. L'eau d'aspersion est recueillie en partie basse et ré-injectée dans les buses d'aspersion. Un fonctionnement par circulation de gaz saturé en vapeur d'eau pourrait également être retenu.This embodiment also makes it possible to envisage a sprinkler operation by equipping the structure with sprinkler nozzles fixed for example on the bastaings lateral. The presence of cover element 2 waterproof prefabricates suppresses evaporation and allows couple anaerobic mode with hygrometry mode maximum of 100%. The sprinkling water is collected in lower part and re-injected into the spray nozzles. A operation by circulation of vapor saturated gas water could also be retained.

    Comme mentionné en introduction, tout ce qui vient d'être décrit ci-dessus peut s'appliquer de manière analogue au stockage et à la conservation de tout autre type de produit organique biodégradable conditionné ou non. Ainsi, l'abri peut plus particulièrement être utilisé pour le stockage et la conservation de produits pulvérulents, en particulier des farines animales. Ces produits pulvérulents pourront être stockés en vrac sous l'abri. Une solution préférée consiste toutefois à conditionner ces produits pulvérulents à l'intérieur de conteneurs souples de grande contenance dits "big-bag" fermés de manière étanche et munis d'un dispositif d'échappement des gaz en cas de surpression à l'intérieur du conteneur. Ces conteneurs seront ensuite empilés sous forme d'un tas de forme analogue à celui obtenu au moyen de grumes. Cette solution de stockage s'avère plus fiable que celle obtenue au moyen des hangars rigides utilisés jusqu'à ce jour. Dans ce cas, la grume témoin décrite ci-dessus sera remplacée par un échantillon témoin de produits pulvérulents.As mentioned in the introduction, everything that has just been described above can be applied analogously to storage and preservation of any other type of product organic biodegradable conditioned or not. So the shelter can more particularly be used for storage and the conservation of powdery products, in particular animal meal. These powdery products may be stored in bulk under the shelter. A preferred solution however, consists in packaging these powdery products inside flexible containers of large capacity so-called "big-bags" sealed and equipped with a gas exhaust system in the event of overpressure inside the container. These containers will then stacked in a pile of shape similar to that obtained by means of logs. This storage solution more reliable than that obtained from hangars rigid used to date. In this case, the log witness described above will be replaced with a sample witness of powdery products.

    Bien évidemment, l'abri peut être logé à l'intérieur de conteneurs ou de bâtiments.Obviously, the shelter can be housed inside containers or buildings.
