Description

Module pour la réalisation d'un Matériel Ambidrome de Franchissement  Module for the realization of an Ambidrome Crossing Material
(MAF)  (MY F)
La présente invention se rapporte à un module pour la réalisation d'un Matériel Ambidrome de Franchissement (MAF) et plus particulièrement de type bac modulaire pour la traversée de cours d'eau, les modules pouvant éventuellement également être accouplés pour former un pont. The present invention relates to a module for the production of an Ambidrome Crossing Equipment (MAF) and more particularly of the modular tank type for the crossing of streams, the modules possibly also being coupled to form a bridge.
La présente invention se rapporte également à une interface de chargement dédiée pour ledit module.  The present invention also relates to a dedicated loading interface for said module.
Les bacs et ponts flottants sont principalement destinés à permettre à des véhicules militaires de franchir un fleuve ou une rivière en dehors de tout pont ou autre système de bac installé à demeure. Les applications peuvent être également civiles, après des crues ou inondations par exemple ou pour la traversée d'une rivière en l'absence d'ouvrage permanent et notamment pour permettre le passage de véhicules lourds de chantier ou d'intervention par exemple.  The floating bins and decks are intended primarily to allow military vehicles to cross a river or river outside any deck or other permanently installed ferry system. The applications can also be civil, after floods or flood for example or for the crossing of a river in the absence of permanent work and in particular to allow the passage of heavy vehicles for construction or intervention for example.
Les véhicules plus particulièrement visés sont des véhicules à chenilles ou à roues de masse moyenne pouvant atteindre 30 à 60 tonnes.  The most particularly targeted vehicles are tracked or wheeled vehicles of average mass of up to 30 to 60 tons.
Les modules constitutifs du bac ou du pont ad hoc peuvent notamment être amenés au point de franchissement désiré et assemblés.  The constituent modules of the tank or the ad hoc bridge can in particular be brought to the desired crossing point and assembled.
De manière générale, un bac ou pont flottant est réalisé à partir d'un ou plusieurs caissons de flottaison, éventuellement motorisés, et conçus pour supporter une voie de roulement pour la circulation des véhicules sur le bac ou sur le pont.  In general, a floating ferry or deck is made from one or more buoyancy chambers, possibly motorized, and designed to support a raceway for the circulation of vehicles on the ferry or on the deck.
De manière complémentaire, ledit pont ou bac pourra être terminé à l'une ou à ses deux extrémités par une rampe d'accès, généralement repliable, ou rég l abl es ang u la i rement, permettant l e ch a rg em ent et déchargement des véhicules transportés. Avantageusement toutefois, le bac ou pont sera ambidrome.  In a complementary manner, said bridge or ferry can be terminated at one or at both ends by an access ramp, generally folding, or reg l abl abl ably, allowing the ch anging and unloading transported vehicles. Advantageously, however, the ferry or deck will be ambidrome.
Dans le cas d'un assemblage en pont flottant, le nombre de modules assemblés dépendra de la distance à franchir et des caractéristiques de flottaison des caissons de flottaison. Dans le cas d'un assemblage en bac de transport, le nombre de modules assemblés dépendra bien évidemment des véh icules à transporter a i n s i q u e d e l e u r ch a rg e e n fo n ct io n d es caractéristiques de flottaison des caissons. Il n'existe pas de module autonome contenant l'ensemble des éléments nécessaires à l'assemblage du bac ou du pont flottant à réaliser, à l'exception des véhicules autonomes motorisés et amphibies tel que les Engins de Franchissement de l'Avant (EFA). De tels engins ne sont pas aisément déplaçables loin de leur point d'attache, notamment par voie aérienne et restent relativement chers puisque possédant leur propre système moteur amphibie requérant également une maintenance plus importante. In the case of a floating bridge assembly, the number of assembled modules will depend on the distance to be traveled and the floatation characteristics of the floats. In the case of a transport bin assembly, the number of assembled modules will of course depend on the vehicles to be transported as well as on the type of floatation characteristics of the caissons. There is no autonomous module containing all the elements necessary for the assembly of the ferry or floating bridge to be made, with the exception of autonomous motorized and amphibious vehicles such as Forward Crossing Machines (EFA). ). Such devices are not easily movable far from their point of attachment, especially by air and remain relatively expensive since having their own amphibious engine system also requiring greater maintenance.
Concernant les systèmes transportables, il existe des bacs et ponts flottants réalisés à partir de bateaux sur lesquels des travures, éléments constitutifs de la voie de roulage finale, sont installées transversalement aux bateaux.  Concerning the transportable systems, there are floating bins and bridges made from boats on which deck pieces, constituent elements of the final taxiway, are installed transversely to the boats.
L'assemblage d'un bac ou pont flottant actuellement nécessite donc le transport desdits bateaux, des travures, des moteurs à installer sur les bateaux, etc ... soit de nombreux constituants épars rendant généralement difficile leur acheminement rapide sur site.  The assembly of a ferry or floating bridge currently requires the transport of said boats, bridges, engines to install on boats, etc ... or many scattered components generally difficult to quickly get on site.
De plus, les différents éléments étant séparés, l'assemblage nécessite un temps relativement important et reste complexe, le poids de chaque élément devant être porté par un homme ne devant pas dépasser les limites militaires .  In addition, the different elements being separated, the assembly requires a relatively long time and remains complex, the weight of each element to be worn by a man not to exceed the military limits.
La présente invention vise à proposer un module permettant la réalisation d'un bac ou d'un pont flottant modulaire regroupant le maximum, et de préférence la total ité, des éléments constitutifs et sim pl ifiant en conséquence les opérations d'assemblage.  The present invention aims to provide a module for the realization of a modular floating deck or bridge grouping together the maximum, and preferably the totality, of the constituent elements and simplifying the assembly operations accordingly.
Un tel module doit bien évidemment rester aisément acheminable sur site et doit respecter les normes mil itaires internationales et répondre notamment aux contraintes de masses et de dimensions de gabarit routier, aérien et ferroviaire.  Such a module must of course be easily transportable on site and must comply with international milíary standards and respond in particular to the constraints of masses and dimensions of road, air and rail gauge.
Pour ce faire, la présente invention se rapporte à un module pour la réalisation d'un bac et/ou pont flottant modulaire comprenant un caisson de flottaison, caractérisé en ce que ledit caisson de flottaison est réalisée sous la forme de deux demi-caissons de flottaison articulés entre eux autour d'une ligne d'articulation entre une position d'ouverture dans laquelle les deux demi- caissons sont sensiblement alignés et forment le caisson de flottaison, et une position de fermeture dans laquelle un demi-caisson est rabattu sur l'autre demi-caisson à la manière d'un couvercle formant ainsi une boîte container renfermant tout ou partie des éléments de réalisation du bac ou pont flottant. Ainsi, en prévoyant un caisson de flottaison en deux demi-caissons articulés l'un sur l'autre, ledit caisson de flottaison se transforme en boîte pour le rangement d'au moins une partie, et de préférence la totalité, des divers éléments constitutifs du bac ou pont mobile. To do this, the present invention relates to a module for the realization of a modular tank and / or floating bridge comprising a buoyancy chamber, characterized in that said buoyancy chamber is made in the form of two half-boxes of floatation hinged together about a hinge line between an open position in which the two half-boxes are substantially aligned and form the buoyancy chamber, and a closed position in which a half-box is folded over the other half-box in the manner of a lid thus forming a container box containing all or part of the elements of realization of the tray or floating bridge. Thus, by providing a floating caisson in two half-boxes articulated one on the other, said flotation box is transformed into a box for the storage of at least a portion, and preferably all, of the various constituent elements ferry or moving bridge.
Généralement, pour la réal isation d'un bac, il suffira donc de transporter deux caissons de flottaison / boîtes selon l'invention, ces boîtes contenant les éléments essentiels et nécessaires pour la réalisation du bac qui est peut donc être commencée immédiatement.  Generally, for the realization of a tray, so it will be sufficient to transport two caissons / boxes according to the invention, these boxes containing the essential elements and necessary for the realization of the tray which can be started immediately.
Il en résulte un gain logistique important dû à la facilité de transport et la rapidité d'installation.  This results in a significant logistical gain due to the ease of transport and the speed of installation.
Avantageusement, les demi-caissons sont équipés d'au moins un moyen mécanique d'aide à l'ouverture et fermeture, notamment du type vérin.  Advantageously, the half-boxes are equipped with at least one mechanical means of assistance for opening and closing, in particular of the jack type.
Avantageusement encore, au moins l'un des deux demi-caissons comprend au moins un moyen de propulsion et de d irection aquatique, notamment de type propulseur à jet d'eau, préférentiellement orientable. On pourra notamment prévoir un propulseur principal, notamment orientable, et des propulseurs secondaires de complément de direction. Ainsi, il ne sera pas nécessaire de prévoir l'installation de propulseurs extérieurs rapportés sur le caisson de flottaisson, le caisson / boîte selon l'invention pouvant renfermer ses propres moyens de motorisation et de propulsion.  Advantageously, at least one of the two half-boxes comprises at least one means of propulsion and aquatic disrection, especially water-jet propellant type, preferably orientable. In particular, it will be possible to provide a main thruster, in particular steerable, and secondary thrusters for steering complement. Thus, it will not be necessary to provide the installation of external thrusters reported on the float box, the box / box according to the invention may contain its own means of motorization and propulsion.
On visera plus particulierment des moyens de propulsion dont la poussée est prévue pour donner au bac ou au pont des capacités de vitesse sur l'eau d'au moins 4m/s.  More specifically, propulsion means whose thrust is intended to give the ferry or deck speeding capabilities on the water of at least 4m / s.
Selon une variante de réalisation avantageuse, on pourra prévoir deux propulseurs principaux orientables situés respectivement à l'avant et à l'arriére d'un demi-caisson. Ce mode de réalisation permet une manoeuvrabilité accrue et ne nécessite pas la mise en place de propulseurs secondaires de complément de direction.  According to an advantageous embodiment variant, it is possible to provide two steerable main thrusters located respectively at the front and at the rear of a half-box. This embodiment allows increased maneuverability and does not require the establishment of secondary thrusters of additional direction.
Le moteur pourra également alimenter un ou plusieurs générateurs hydraulique, et/ou électrique, et/ou pneumatique, pour alimenter différents organes, notamment, par exemple des organes de type vérins. Dans le cas où deux moteurs sont installés, cela permettra en outre une redondance de ses fonctions, notam ment de générateu r pneu matiq ue, hyd rau l iq ue, et/ou électrique.  The motor may also power one or more hydraulic generators, and / or electric, and / or pneumatic, to supply different organs, including, for example, type of actuators. In the case where two motors are installed, this will also provide redundancy of its functions, including general mot r u rt, hyd rau l ic, and / or electric.
De manière préférentielle, au moins un demi-caisson comprend au moins un flotteur d'étrave, préférentiellement gonflable. Un tel flotteur d'étrave permettra notamment au module d'avoir une traînée compatible avec la poussée des propulseurs pour obtenir les capacités souhaitées de vitesse sur l'eau. Preferably, at least one half-box comprises at least one bow float, preferably inflatable. Such a bow float will in particular allow the module to have a drag compatible with the thrust of the thrusters to obtain the desired speed capabilities on the water.
Avantageusement, au moins l'un, et préférentiellement chacun, des demi-caissons renferme au moins un élément de travure monté mobile entre une position de rangement dans une partie basse du demi-caisson et selon une direction sensiblement longitudinale dudit demi-caisson, et une position déployée dans laquelle l'élément de travure vient sensiblement au dessus du demi-caisson et est orienté sensiblement selon une direction transversale au demi-caisson à proximité d'une ligne médiane du caisson de flottaison.  Advantageously, at least one, and preferably each, of the half-boxes contains at least one spacer element mounted movably between a storage position in a lower part of the half-box and in a substantially longitudinal direction of said half-box, and an extended position in which the bridging element comes substantially above the half-box and is oriented substantially in a direction transverse to the half-box near a median line of the buoyancy chamber.
Avantageusement encore, l'élément de travure est monté sur un moyen de levage du type vérin apte à soulever ledit élément de travure depuis sa position de rangement en partie basse du demi-caisson jusqu'à au moins une hauteur correspondante à sa position déployée.  Advantageously, the bridging element is mounted on a jack type lifting means capable of lifting said bridging element from its storage position in the lower part of the half-box to at least one height corresponding to its deployed position.
De manière avantageusement complémentaire, l'élément de travure est monté pivotant d'au moins 90 degrés, entre une orientation longitudinale au demi-caisson et une orientation transversale audit demi- caisson.  Advantageously complementary, the bridging element is pivotally mounted at least 90 degrees, between a longitudinal orientation to the half-box and a transverse orientation to said half-box.
De manière complémentaire encore, l'élément de travure monté translatable selon une direction sensiblement longitudinale du demi-caisson de manière à pouvoir l'amener de sa position de rangement, vers sa position de déploiement à proximité de la ligne médiane du caisson de flottaison.  In a further complementary manner, the bridging element mounted translatable in a substantially longitudinal direction of the half-box so as to bring it from its storage position to its deployment position near the median line of the buoyancy chamber.
Préférentiellement, chaque dem i-caisson renferme u ne dem i- travure. Cela permet notamment d'équilibrer les charges lors de la mise à l'eau du caisson de flottaison déployé.  Preferably, each demi-box contains a demi-bay. This allows in particular to balance the loads when launching the deployed floatation chamber.
De manière avantageuse, le module, en position de fermeture est apte à renfermer également un ou plusieurs éléments de rampe constitutifs d'au moins une rampe d'accès destinée à être installé à une extrémité de travure formée de ses éléments de travure.  Advantageously, the module, in the closed position is also able to contain one or more ramp elements constituting at least one access ramp intended to be installed at a bridging end formed of its bridging elements.
Préférentiellement, au moins une et avantageusement les deux extrémités de travure constituée de ses éléments de travure sont équipées de moyens de liaison à une extrémité d'une travure également constituée de ses éléments de travure d'un deuxième module en position déployée. Il pourra notamment s'agir de chapes aptes à coopérer par complémentarité de forme et aptes à recevoir un axe de maintien. De manière avantageusement complémentaire, au moins un demi- caisson comprend au moins un élément d'un mât dépliable formant potence de manutention, ledit caisson étant apte à contenir la potence en position repliée. Preferably, at least one and advantageously both bridging ends consisting of its bridging elements are equipped with connecting means at one end of a bridging also consisting of its bridging elements of a second module in the deployed position. It may in particular be screeds adapted to cooperate by complementary shape and able to receive a maintenance axis. Advantageously complementary, at least one half-box comprises at least one element of a folding mast forming a handling bracket, said box being adapted to contain the bracket in the folded position.
Cette potence pou rra également servir le cas échéant à la manutention et au levage des éléments de travure, notamment à leur pivotement et / ou à leur translation.  This bracket can also serve if necessary to the handling and lifting of bridging elements, including their pivoting and / or translation.
Cette potence permet en outre de modifier la place des rampes et éventuellement des travures en fonction des configurations de transport ou de travail en bac ou en pont. En configuration de transport, la potence est repliée.  This stem also allows to change the place of the ramps and possibly bridges depending on transport configurations or work tray or bridge. In transport configuration, the stem is folded.
Le mât dépliable pourra comprendre notamment plusieurs secteurs articulés les u ns su r les autres et config urés de man ière tel le q ue le redressement d'un secteur inférieur, notamment à l'aide d'un vérin ou autre moyen motorisé, formant pied de mât entraîne le déploiement des autres secteurs articulés.  The foldable mast may comprise in particular several articulated sectors u ns su r the others and config urés such as q ue the rectification of a lower sector, especially with the aid of a cylinder or other motorized means, forming foot the deployment of the other articulated sectors.
Alternativement, il pourra par exemple s'agir d'un mât télescopique ou encore d'un pied de mât apte à recevoir ledit mât de manière démontable. Un tel mât déployable permettra aux opérateurs d'effectuer la manutention des divers éléments, et notamment des éléments de rampe.  Alternatively, it may for example be a telescopic mast or a mast base adapted to receive said mast removably. Such a deployable mast will allow operators to handle the various elements, including ramp elements.
Préférentiellement, au moins une extrémité de travure est équipée d'au moins une partie orientable motorisé, notamment par au moins un vérin, et notamment apte à orienter la rampe d'accès le cas échéant. Par ailleurs, lorsqu'une extrémité ne sera pas équipée de rampe d'accès, ces parties orientables permettront d'assurer la planéité et le bon nivellement des travures entre deux modules formant bac.  Preferably, at least one sparer end is equipped with at least one motorized steerable part, in particular with at least one jack, and in particular capable of orienting the access ramp, as the case may be. In addition, when one end will not be equipped with an access ramp, these orientable parts will make it possible to ensure the flatness and the good leveling of the bridges between two modules forming a tray.
De manière avantageusement complémentaire, la travure est équipée d'au moins un moyen de centrage et d'indexation, préférentiellement déployable, notamment à l'aide d'un ou plusieurs vérins, apte à coopérer avec un moyen de centrage et d'indexation correspondant d'une travure d'un deuxième module. Les moyens de centrage et d'indexation pourront se présenter sous la forme de bras d'indexation situés sous la travure présentant une extrémité sensiblement triangulaire ou conique, et apte à pénétrer dans un logement correspondant d'une travure d'un deuxième module déployé.  Advantageously complementary, the span is equipped with at least one centering and indexing means, preferably deployable, in particular with the aid of one or more jacks, adapted to cooperate with a means of centering and indexing corresponding of a span of a second module. The centering and indexing means may be in the form of indexing arms located under the span having a substantially triangular or conical end, and adapted to penetrate into a corresponding housing of a span of a second deployed module.
Avantageusement, le module est équipé d'au moins un moyen de préhension par un bras polybenne, notamment du type arceau.  Advantageously, the module is equipped with at least one gripping means by a polybenne arm, in particular of the hoop type.
La présente invention se rapporte encore à une interface support pour le transport d'un module selon l'invention, comprenant un plateau de transport destiné à recevoir ledit module et équipé d'au moins un moyen de préhension par un bras polybenne caractérisé en ce que ledit plateau de transport est équipé d'au moins un chariot monté mobile en translation le long du plateau de transport entre une position de récupération dans laquelle le chariot est située à proxim ité d'une extrém ité du plateau de man ière à permettre l'accroche et la récupération du module à transporter et une position de transport dans laquelle le chariot est remonté vers le moyen de préhension par le bras polybenne en vue de tirer le module sur le plateau. The present invention also relates to a support interface for transporting a module according to the invention, comprising a platter of transport intended to receive said module and equipped with at least one gripping means by a polybenne arm characterized in that said transport tray is equipped with at least one carriage mounted to move in translation along the transport tray between a position of recovery in which the carriage is located near one end of the tray so as to allow the hooking and recovery of the module to be transported and a transport position in which the carriage is raised to the gripping means by the polybenne arm to pull the module on the tray.
Cette interface est destinée à faciliter grandement le transport, la mise à l'eau et la récupération des modules selon l'invention tant avec des berges à bord franc qu'au niveau de berges inclinées.  This interface is intended to greatly facilitate the transport, launching and recovery of the modules according to the invention both with banks with straight edge at the level of inclined banks.
Cette interface, et plus particulièrement le bras polybenne, permet également la mise à terre du module, sa pose sur un wagon, par exemple, ou sur une rampe d'accès d'un avion cargo.  This interface, and more particularly the polybenne arm, also allows the grounding of the module, its installation on a car, for example, or on an access ramp of a cargo plane.
La présente invention sera mieux comprise à la lumière de la description détaillée qui suit en regard du dessin annexé dans lequel :  The present invention will be better understood in the light of the following detailed description with reference to the appended drawing in which:

Les figures 1 et 2 montrent un module 1 selon l'invention pour la réalisation d'un bac modulaire pour la traversée de cours d'eau, les modules 1 pouvant éventuellement également être accouplés pour former un pont.  Figures 1 and 2 show a module 1 according to the invention for the realization of a modular tank for the crossing of streams, the modules 1 may optionally also be coupled to form a bridge.
Conformément à l'invention, ce module 1 comprend un caisson de flottaison 2 réalisé sous la forme de deux demi-caissons de flottaison 2a, 2b. Les deux demi-caissons de flottaison 2a, 2b sont articulés entre eux autour de pièces de pivotement 3 le long d'une ligne d'articulation A entre une position d'ouverture (figure 2) dans laquelle les deux demi-caissons 2a, 2b sont sensiblement alignés et forment le caisson de flottaison 2, et une position de fermeture dans laquel le u n dem i-caisson est rabattu su r l'autre dem i- caisson à la manière d'un couvercle formant ainsi une boîte container apte à renfermer des éléments de réalisation du bac ou pont flottant. According to the invention, this module 1 comprises a buoyancy chamber 2 made in the form of two half-floating caissons 2a, 2b. The two half-water boxes 2a, 2b are hinged together around pivoting parts 3 along a hinge line A between an open position (Figure 2) in which the two half-boxes 2a, 2b are substantially aligned and form the buoyancy chamber 2, and a closed position in which the one half i-box is folded on the other demi-caisson in the manner of a lid thus forming a container box able to contain elements of realization of the ferry or floating bridge.
La figure 1 montre le module 1 en position de fermeture, c'est-à- dire formant une boîte destinée à contenir des éléments constitutifs du bac, un demi-caisson de flottaison 2b formant un couvercle de la boîte.  Figure 1 shows the module 1 in the closed position, that is to say forming a box for containing the constituent elements of the tray, a half-flotation chamber 2b forming a lid of the box.
La fig ure 2 montre le mod ule 1 en position d 'ouvertu re, dans laquelle le demi-caisson de flottaison 2b formant le couvercle de la boîte a été pivoté autour de la ligne d'articulation A de manière à venir dans l'alignement du premier demi-caisson de flottaison 2a, formant ainsi le caisson de flottaison 2 complet.  Fig ure 2 shows the model 1 in the open position, in which the buoyancy half-box 2b forming the lid of the box has been pivoted about the hinge line A so as to come into alignment of the first half-water box 2a, thus forming the complete water box 2.
De manière à permettre aux opérateurs l'ouverture du module 1 , les demi-caissons 2a, 2b sont équipés d'au moins un moyen mécanique d'aide à l'ouverture et fermeture, notamment du type vérin . En l'espèce, ces moyens mécaniques se présentent sous la forme de vérins 4 latéraux, présentant une prem ière extrém ité l iée à u n des dem i-caissons 2a, 2b et u ne deuxième extrém ité l iée à une pièce de pivotement 3 de man ière à permettre aux opérateurs d'ouvrir le module 1 .  In order to allow the operators to open the module 1, the half-boxes 2a, 2b are equipped with at least one mechanical means of assistance for opening and closing, in particular of the jack type. In the present case, these mechanical means are in the form of lateral cylinders 4, having a first extremity l ized to one of the demi-caissons 2a, 2b and u second second end l ied to a pivoting piece 3 to allow operators to open module 1.
Ces vérins 4 pourront être al imentés par un générateur d'appoint externe, par exemple, ou éventuellement directement par un générateur interne au module 1 et démarré depuis l'extérieur.  These cylinders 4 may be supplied by an external auxiliary generator, for example, or possibly directly by an internal generator module 1 and started from the outside.
Da n s l e cas d ' u n générateur interne, ce dern ier pou rra être alimenté par un moteur interne au module, démarré depuis l'extérieur, et prévu notamment pour entraîner des moyens de propulsions et d'autres générateurs le cas échéant (générateur électriques, hydrauliques, pneumatiques).  In the case of an internal generator, the latter can be powered by an internal motor module, started from the outside, and provided in particular to drive propulsion means and other generators if necessary (electrical generator, hydraulic, pneumatic).
A cette fin, le module 1 comprend deux blocs moteur 5 alimentant en puissance chacun un moyen de propulsion associé du type propulseur à jet d'eau et disposés dans un fond du premier caisson de flottaison 2a, celui-ci étant pourvu d'ouvertures en conséquence.  To this end, the module 1 comprises two engine blocks 5 each supplying power to a propulsion means associated with the waterjet propellant and arranged in a bottom of the first buoyancy chamber 2a, the latter being provided with openings result.
En l'espèce, le demi-caisson 2b forme donc un caisson de proue tandis que le demi-caisson 2a forme un caisson de poupe. Ces moyens de propulsion sont orientables et permettent une grande manœuvrabilité du caisson de flottaison 2. Le bloc moteur associé à un moyen de propulsion forme un groupe moto-propulseur. In this case, the half-box 2b thus forms a bow box while the half-box 2a forms a stern box. These propulsion means are steerable and allow great maneuverability of the buoyancy chamber 2. The engine block associated with a propulsion means forms a powertrain.
Plus précisément et de manière préférentielle, les propulseurs seront donc des propulseurs à jet d'eau orientables et dont la sortie d'eau propulsée est inclinée d'environ 15 degrés sous la coque du demi-caisson de flottaison 2a. Ainsi, un tel propulseur permet une navigation avec une faible hauteur d'eau sous la coque (jusqu'à quelques centimètres).  More specifically and preferably, the thrusters will therefore be steerable waterjet thrusters and the output of propelled water is inclined by about 15 degrees below the hull half buoyancy chamber 2a. Thus, such a propeller allows navigation with a low water level under the hull (up to a few centimeters).
Par ailleurs, comme mentionnée précédemment, les blocs moteurs 5 pourront chacun comprendre une fonction de générateur hydraulique et/ou électrique et/ou pneumatique.  Furthermore, as mentioned above, the engine blocks 5 may each include a hydraulic generator function and / or electric and / or pneumatic.
La présence de deux blocs moteurs 5 permet une redondance de sécurité de ces fonctionnalités et de la propulsion.  The presence of two engine blocks 5 allows a redundancy of safety of these features and propulsion.
Alternativement, d'autres systèmes de propulsion peuvent être mis en œuvre.  Alternatively, other propulsion systems can be implemented.
Ainsi, on pourra prévoir un seul bloc moteur alimentant en puissance un moyen de propulsion principal du type propulseur à jet d'eau et d isposé au fond du prem ier ca isson de flottaison 2a, et qu i permettra également l'alimentation de propulseurs d'appoint de direction, notamment de propulseurs d'étrave situés à proximité d'une extrémité avant du deuxième demi-caisson 2b et/ou à l'arrière du demi-caisson 2a.  Thus, it will be possible to provide a single power unit supplying power to a main propulsion means of the waterjet propellant type and positioned at the bottom of the first floatation circuit 2a, and that it will also make it possible to supply propulsion engines. additional steering, including bow thrusters located near a front end of the second half-box 2b and / or the rear of the half-box 2a.
Avantageusement, le moyen de propulsion principal sera pareillement orientable. On pourra également prévoir deux propulseurs secondaires, positionnés l'un à l'avant (demi-caisson 2b) et l'autre à l'arrière (demi-caisson 2a), chaque propulseur comprenant une hélice disposée dans un tube sensiblement horizontal débouchant sous la ligne de flottaison.  Advantageously, the main propulsion means will be similarly rotatable. It will also be possible to provide two secondary thrusters, positioned one at the front (half-box 2b) and the other at the rear (half-box 2a), each thruster comprising a helix disposed in a substantially horizontal tube opening under the waterline.
Les propulseurs secondaires pourront être utilisés pour corriger la trajectoire du caisson de flottaison 2, notamment lors des manœuvres d'accouplements entre modules 1 pour constituer un bac ou pont flottants et lors des manœuvres de navigation du bac constitué.  The secondary thrusters may be used to correct the trajectory of the buoyancy chamber 2, in particular during the coupling maneuvers between modules 1 to form a floating ferry or deck and during navigation maneuvers of the tank formed.
Les moyens de propulsion sont complétés par un poste de pilotage 7, éventuellement démontable et rangeable dans un dem i-caisson 2a ou emportable par le pilote. Le bloc moto-propulseur 5 sera de préférence également apte à alimenter un ou plusieurs équipements de génération de puissance hydraulique, électrique ou pneumatique. De manière à améliorer les performances de navigation, le demi- caisson 2b formant proue sera équipé d'un flotteur d'étrave 8, glonflable, et protégé par une plaque métallique pour réaliser les accostages sur les bords de berges. Cette plaque 8 est repliable contre le demi-caisson 2b lorsque le flotteur est dégonflé et que le module 1 est en position de fermeture. The propulsion means are completed by a cockpit 7, possibly removable and stored in a demi-box 2a or transportable by the pilot. The power unit 5 will preferably also be able to power one or more hydraulic power generation equipment, electrical or pneumatic. In order to improve navigation performance, the bow-shaped half-box 2b will be equipped with a bow thruster 8, glonflable, and protected by a metal plate to make the berthing on the edges of the banks. This plate 8 is foldable against the half-box 2b when the float is deflated and the module 1 is in the closed position.
Conformément à l'invention , le module 1 abrite, en position de fermeture tout ou partie des éléments constitutifs du bac à réaliser.  According to the invention, the module 1 houses, in the closed position all or part of the constituent elements of the tray to achieve.
Plus précisément, chaque demi-caissons 2a , 2b renferme un élément de travure 1 0a, 1 0b monté mobile entre une position de rangement d a ns u n e pa rtie basse d u d em i-caisson 2a, 2b et selon u ne d irection sensiblement longitudinale dudit demi-caisson, et une position déployée dans laquelle l'élément de travure 10a, 10b vient sensiblement au dessus du demi- caisson 2a, 2b et est orienté sensiblement selon une direction transversale au demi-caisson à proximité d'une ligne médiane du caisson de flottaison.  More precisely, each half-casing 2a, 2b encloses a bridging element 1 0a, 1 0b movably mounted between a storage position in a low section of the casing 2a, 2b and according to a substantially longitudinal direction of said half-box, and an extended position in which the bridging element 10a, 10b comes substantially above the half-box 2a, 2b and is oriented substantially in a direction transverse to the half-box near a center line of the box of flotation.
La figure 2 montre les éléments 10a, 10b de travure 10 en position de rangement dans leur demi-caisson 2a, 2b respectif. L'élément de travure 1 0a reposant sur les blocs moto-propulseur 5, il est surélevé par rapport à l'élément 10b de l'autre demi-caisson caisson 2b.  Figure 2 shows the elements 10a, 10b of bridging 10 in storage position in their respective half-box 2a, 2b. The bridging element 1 0a resting on the motor-booster blocks 5, it is raised relative to the element 10b of the other box half-box 2b.
Chaque demi-caisson 2a, 2b comprend un élément de travure 10a, 10b formant plus précisément chacun une demi-travure.  Each half-box 2a, 2b comprises a bridging element 10a, 10b each more precisely forming a half-span.
Ainsi, une travure 10 destinée à former une voie de 4m de large pour le passage des véhicules sera réalisée à partir de deux demi travure 10a, 1 0b d'environ deux mètres de large chacune, et plus précisément d'environ 1 ,8m chacune pour tenir compte de divers espaces intersticiels. La longueur de chaque élément 10a, 10b de travure 10 est légèrement inférieure à la longueur de chaque demi-caisson 2a, 2b.  Thus, a span 10 intended to form a path of 4m wide for the passage of vehicles will be made from two half-span 10a, 10b of about two meters wide each, and more precisely about 1.8 m each to account for various interstitial spaces. The length of each element 10a, 10b of span 10 is slightly less than the length of each half-box 2a, 2b.
Afin de faciliter le passage des éléments de travure 10a, 10b depuis leur position de rangement (longitudinale) vers leur position déployée (transversale), chaque élément 10a, 10b de travure 10 est monté sur un vérin, non visible, sensiblement central, permettant de soulever ledit élément 10a, 10b de travure 10 depuis sa position basse à l'intérieur du caisson de flottaison 2 vers une position haute légèrement au dessus du caisson de flottaison 2 de manière à permettre sa rotation vers une orientation sensiblement transversale.  In order to facilitate the passage of the bridging elements 10a, 10b from their (longitudinal) storage position to their deployed (transverse) position, each element 10a, 10b of bridging element 10 is mounted on a jack, not visible, substantially central, allowing lifting said element 10a, 10b of span 10 from its low position inside the buoyancy chamber 2 to a high position slightly above the buoyancy chamber 2 so as to allow its rotation to a substantially transverse orientation.
Pour ce faire, l'élément 10a, 10b de travure 10 est donc également monté pivotant sur son vérin de levage, ou le vérin de levage est lui-même apte à pivoter. Avantageusement, l'élément 1 0a, 1 0b de travure 10 pourra être pivoté indifféremment dans un sens de rotation ou dans l'autre. En effet, selon la configuration des moyens d'accouplement présentés par l'autre module 1 , il pourra être nécessaire de placer la travure 10 dans un sens ou dans l'autre. To do this, the element 10a, 10b bridging 10 is also pivotally mounted on its lifting cylinder, or the lifting jack is itself pivotable. Advantageously, the element 1 0a, 1 0b bridging 10 can be rotated indifferently in one direction of rotation or in the other. Indeed, depending on the configuration of the coupling means presented by the other module 1, it may be necessary to place the bridge 10 in one direction or the other.
La mise en place de l'élément 10a, 10b de travure 10 est complété par une translation selon une direction sensiblement longitudinale du demi- caisson 2a, 2b vers une zone sensiblement médiane du caisson de flottaison 2 (à l'équilibre des charges près).  The placement of the element 10a, 10b of span 10 is completed by a translation in a substantially longitudinal direction of the half-chamber 2a, 2b to a substantially median zone of the buoyancy chamber 2 (at the equilibrium of the loads) .
Ainsi, les deux éléments de travure 10a, 10b se rejoignent à proximité d'une ligne médiane pour former la travure 10 présentant la largeur totale souhaitée égale à deux fois la largeur d'une demi-travure 10a, 1 0b, et constituant ainsi une voie de roulement pour les véhicules à transporter.  Thus, the two bridging elements 10a, 10b meet near a center line to form the span 10 having the desired total width equal to twice the width of a half-span 10a, 1 0b, and thus constituting a track for vehicles to be transported.
Une fois les éléments de travures 10a, 10b, en place, la constitution d'un bac 100 peut commencer.  Once the elements 10a, 10b, in place, the constitution of a tray 100 can begin.
Un bac 1 00, tel que représenté sur les figures 4 et 5 est réalisé à partir de deux modules 1 par accouplement des travures 10 de chaque module 1 .  A tray 1 00, as shown in Figures 4 and 5 is made from two modules 1 by coupling the bridges 10 of each module 1.
Pour ce faire, chaque extrémité de travure 10 du premier module 1 est équipée de moyens de liaison à une extrémité d'une travure 10 du deuxième module 1 en position déployée. Il pourra notamment s'ag ir d'un système de chapes 1 1 aptes à coopérer par complémentarité de forme et solidarisées par l'insertion d'axes (non visibles).  To do this, each end of span 10 of the first module 1 is equipped with connection means at one end of a span 10 of the second module 1 in the deployed position. It may in particular be a system of clevis 1 1 able to cooperate by complementarity of form and secured by the insertion of axes (not visible).
Avantageusement, les axes pourront être montés à une extrémité de travure et actionné mécaniquement, par exemple à l'aide d'un vérin.  Advantageously, the axes may be mounted at one end of the span and mechanically actuated, for example by means of a jack.
Par ailleurs, afin de facil iter l'accouplement des modules 1 , les travures 1 0 seront avantageusement équ ipées de moyens de centrage et d'indexation déployables, se présentant notamment sous la forme de bras d'indexation 12 déployés à l'aide de vérins et apte à pénétrer dans un logement 13 correspondant de la travure 10 du deuxième module 2.  Moreover, in order to facilitate the coupling of the modules 1, the bridges 1 0 will advantageously be equipped with deployable centering and indexing means, in particular being in the form of indexing arms 12 deployed with the aid of jacks and adapted to penetrate into a corresponding housing 13 of the span 10 of the second module 2.
II convient de noter que le bras d'indexation 12 est disposé dans la continuité du logement 1 3 traversant. Ainsi, un seul élément de centrage et d'indexation central peut être prévu pouvant en fonction des besoins servir d'élément mâle (bras 1 2 sorti traversant le logement 13) ou femelle (bras 1 2 rétracté et logement 1 3 libre pour recevoir un bras 12 de l'élément de travure 10a à accoupler. On notera qu'une extrémité de chaque demi-travure 10a, 10b est équipée d'au moins une partie 16 orientable, sur une face interne de laquelle est disposé le logement 13, associée à un actionneur, notamment au moins un vérin, et notamment apte à orienter une rampe d'accès 15 le cas échéant et la bloquer en position lors du passage des véhicules. Dans le cas d'un pont, les parties 16 non utilisés pour l'installation d'une rampe 15 seront maintenus sensiblement horizontales et assureront le nivellement de la voie de roulement. It should be noted that the indexing arm 12 is disposed in the continuity of the housing 1 3 through. Thus, a single central centering and indexing element can be provided that can, depending on the needs, serve as a male element (arm 1 2 extended through the housing 13) or female (arm 1 2 retracted and housing 1 3 free to receive a arm 12 of the bridging element 10a to be coupled. Note that one end of each half-span 10a, 10b is equipped with at least one orientable portion 16, on an inner face of which is disposed the housing 13, associated with an actuator, in particular at least one jack, and in particular adapted to guide an access ramp 15 if necessary and block it in position during the passage of vehicles. In the case of a bridge, the parts 16 not used for the installation of a ramp 15 will be maintained substantially horizontal and will ensure the leveling of the raceway.
Comme mentionné précédemment, chaque module 1, en position de fermeture est apte à renfermer également un ou plusieurs éléments constitutifs d'au moins une rampe d'accès 15 destinée à être installé à une extrémité de travure 10.  As mentioned above, each module 1, in the closed position is able to also contain one or more elements constituting at least one access ramp 15 to be installed at one end of span 10.
Comme pour la travure 10, la rampe 15 se présente sous la forme de deux demi-rampes 15a, 15b stockées séparément dans le module 1 et assemblées pour former la rampe 15.  As for the span 10, the ramp 15 is in the form of two half-ramps 15a, 15b stored separately in the module 1 and assembled to form the ramp 15.
Pour ce faire, chaque demi rampe 15a, 15b est montée sur une extrémité d'une demi-travure 10a, 10b associée, et plus précisément, est rattachées à une partie 16 qui permettra son orientation.  To do this, each half ramp 15a, 15b is mounted on an end of a half-span 10a, 10b associated, and more specifically, is attached to a portion 16 which will allow its orientation.
Les deux demi-rampes 15a, 15b pourront être ensuite éventuellement solidarisées entre elles, à l'aide de moyens de fixation rapides, ou boulonnage afin d'assurer l'unité de la rampe 15.  The two half-ramps 15a, 15b may then be optionally secured to one another by means of fast fastening means, or bolting to ensure the unity of the ramp 15.
Conformément à un aspect avantageux de l'invention, les demi- rampes 15a, 15b seront installées à l'aide d'au moins une potence de manutention 19, équipée notamment d'un treuil hydraulique ou électrique.  According to an advantageous aspect of the invention, the half-ramps 15a, 15b will be installed using at least one handling bracket 19, equipped in particular with a hydraulic or electric winch.
Selon un mode de réalisation avantageux, la potence est réalisée à partir d'un mât dépliable comprenant plusieurs secteurs articulés les uns sur les autres et configurés de manière telle que le redressement d'un secteur inférieur, notamment à l'aide d'un vérin ou autre moyen motorisé, formant pied de mât entraîne le déploiement des autres secteurs articulés.  According to an advantageous embodiment, the bracket is made from a foldable mast comprising several sectors articulated on each other and configured so that the recovery of a lower sector, in particular with the aid of a jack or other motorized means forming a mast base causes the deployment of other articulated sectors.
Alternativement selon un autre mode de réalisation donné à titre d'exemple, la potence pourra être installée sur un mât télescopique fixé dans le caisson 2 sensiblement au niveau de la ligne médiane des deux demi-travures 10a, 10b. Le mât téléscopique pourra être remplacé par un pied de mât apte à recevoir un mât démontable, qui pourra être rangé dans le caisson de flottaison 2.  Alternatively according to another embodiment given by way of example, the bracket may be installed on a telescopic mast fixed in the housing 2 substantially at the center line of the two half-bridges 10a, 10b. The telescopic mast may be replaced by a mast base adapted to receive a removable mast, which can be stored in the water box 2.
Plus précisément, la potence 19 est agencée de manière à pouvoir être déployé entre les demi-travures 10a, 10b en position déployée tra n sversa l e m e n t a u ca i sso n d e fl otta i so n 2 . U n e l ég ère d éco u pe correspondante pourra être prévue sur les bords des demi-travures 1 0a, 1 0b de manière à permettre le passage si nécessaire de ladite potence 1 9 le cas échéant. More specifically, the bracket 19 is arranged to be deployed between the half-bridges 10a, 10b in the deployed position Tra n sversa lementau ca i sso nde fl otta i so n 2. A corresponding eco e pe e e pe pe can be provided on the edges of half-bridges 1 0a, 1 0b so as to allow the passage if necessary of said bracket 1 9 if necessary.
La potence 19 permet la manutention des éléments contenu dans le module 1 et notamment les demi-rampes 1 5a, 1 5b qui sont installées sur leur flan, avant déplacement en position fonctionnelle une fois la demi-rampe 15a, 15b au moins partiellement attachée à la partie 16.  The bracket 19 allows the handling of the elements contained in the module 1 and in particular the half-ramps 1 5a, 1 5b which are installed on their blank, before moving into the operative position once the half ramp 15a, 15b at least partially attached to part 16.
Une rampe d'accès 15 complète, est donc fixée par l'intermédiaire de chapes supérieures des demi-travures 1 0a, 1 0b et plus précisément des parties 16, directement en position fonction nel le et l iaison à des chapes inférieures desdites parties 16.  A complete access ramp 15 is thus fixed by means of upper screeds of the half-spanings 10a, 10b and more specifically parts 16, directly in the operating position and the iaison to lower screeds of said parts 16 .
Avantageusement, le bac 100 réalisé sera ambidrome, le premier module 1 étant équipé d'une rampe pour la montée du ou des véhicules à transporter, le deuxième module étant équipée d'une rampe similaire pour la descente desdits véhicules.  Advantageously, the tray 100 made will be ambideous, the first module 1 being equipped with a ramp for the mounting of the vehicle or vehicles to be transported, the second module being equipped with a similar ramp for the descent of said vehicles.
De manière complémentaire, des guide-roues pourront être stockés le long des travures 1 0 et mis en place à la main. On pourra également prévoir des guide-roues spécifiques aux rampes 15, également mis en place à la main. Ces guide-roues sont constitués, par exemple, de simples cornières tenues au profil de rive par les plots fusibles.  In a complementary manner, wheel guides may be stored along the bridges 1 0 and put in place by hand. We can also provide specific wheel guides 15 ramps, also implemented by hand. These wheel guides consist, for example, simple brackets held at the edge profile by the fusible pads.
Un caillebottis formant un petit platelage central pourra être mis en place pour couvrir l'intervalle entre les deux demi-rampes 15a, 15b.  A grating forming a small central decking may be put in place to cover the gap between the two half-ramps 15a, 15b.
De la même manière, pour les travures 1 0, lorsque la potence 19 est située au niveau de la travure 10, et malgré le rapprochement maximal des éléments de travure 1 0a , 1 0b, il pourra su bsister un intervalle entre les éléments de travure 10a, 10b.  In the same way, for the bridges 1 0, when the bracket 19 is located at the span 10, and despite the maximum approximation of the bridging elements 1 0a, 1 0b, it can suhs bsister a gap between the bridging elements 10a, 10b.
Cet intervalle pourra être avantageusement comblé par la mise en place, notamment manuelle, d'un caillebotis formant également platelage central entre les deux éléments de travure 1 0a, 1 0b. On pourra également prévoir des guides roues latéraux rabattables équipant les éléments de travure 10a, 10b. Les guide roues externes seront relevés pour délimiter le bord de la voie de roulement tandis que les guide-roues internes seront simplement mis à l'horizontal pour couvrir l'intervalle entre les deux éléments de travure 10a, 10b. Une pièce formant traverse pourra être prévue pour lier fermement les deux demi-becs d'extrémité de rampes 15 et assurer une bonne rigidité de la rampe 15 lors de l'embarquement des véhicules. This interval can be advantageously filled by the introduction, including manual, a grating also forming central decking between the two elements of span 1 0a, 1 0b. It may also provide foldable side wheel guides fitted to the bridging elements 10a, 10b. The outer wheel guides will be raised to delineate the edge of the raceway while the inner wheel guides will be simply set horizontally to cover the gap between the two bridging elements 10a, 10b. A crosspiece piece may be provided to firmly bind the two ramp end half-nozzles 15 and ensure good rigidity of the ramp 15 when boarding vehicles.
Après le repli de la potence 1 9, le bac 1 00 ainsi formé à l'aide de deux modules 1 selon l'invention est opérationnel.  After folding the stem 1 9, the tray 1 00 thus formed using two modules 1 according to the invention is operational.
La longueur de chargement hors rampes sera calculée de manière à être com pati ble avec l a long ueu r des véh icu l es à rou es des classes concernées. Les rampes 15 peuvent en parties, être chargées en bac en navigation avec des véh icules légers. Les caractéristiq ues d u caisson de flottaison 2 seront bien évidemment déterminées pour satisfaire aux conditions de flottaison requises.  The length of loading off ramps will be calculated so as to be compatible with the length of the vehicles in the classes concerned. Ramps 15 may be in part, be loaded in ferry while sailing with light vehicles. The characteristics of a buoyancy chamber 2 will obviously be determined to satisfy the required flotation conditions.
Un pont flottant sera constitué de la même manière, et composé d'un nombre nécessaire de modules 2 déployés en fonction de la longueur souhaitée.  A floating bridge will be constituted in the same manner, and composed of a necessary number of modules 2 deployed according to the desired length.
On notera également qu'en dehors d'une utilisation en bac 100 ou en pont flottant, les modules 1 simplement ouverts mais non totalement déployés (figure 2) pourront servir de barge de transport (notamment pour des personnels et des sacs de sable par exemple, ou autre paquetage).  It will also be noted that, apart from use in a tray 100 or a floating bridge, the modules 1 simply open but not fully deployed (FIG. 2) may serve as a transport barge (in particular for personnel and sandbags, for example , or other package).
De manière complémentaire, chaque caisson de flottaison 2 pourra être équipé d'une ancre, préférentiellement installée dans un puits débouchant à travers une paroi du demi-caisson 2b et accrochée à une chaîne. Le largage se fait par gravité et la remontée de l'ensemble pourra être assurée par un guideau hydraulique ou électrique avec commande de secours manuelle, la chaîne pourra être stockée dans un coffre.  In a complementary manner, each buoyancy chamber 2 may be equipped with an anchor, preferably installed in a well opening through a wall of the half-box 2b and attached to a chain. The release is done by gravity and the reassembly of the assembly can be ensured by a hydraulic or electric guide with manual emergency control, the chain can be stored in a safe.
La présente invention se rapporte également à une interface support 200 pour un module 1 selon l'invention. Un exemple de réalisation et d'utilisation d'une telle interface support 200 est représenté aux figures 6 et 7.  The present invention also relates to a support interface 200 for a module 1 according to the invention. An exemplary embodiment and use of such a support interface 200 is shown in FIGS. 6 and 7.
Un module 1 est destiné à être transporté, notamment mais non exclusivement, su r s ite a u moyen de cam ions 300 de transport militaire équipés d'un bras polybenne 301 (connus sous le nom de Porteur Polyvalent Terrestre ou PPT).  A module 1 is intended to be transported, in particular but not exclusively, by means of military transport cameras 300 equipped with a 301 polybag arm (known as the Versatile Versatile Carrier or PPT).
Pour ce faire, l'interface support 200, comprend un plateau de transport 201 destiné à recevoir ledit module 1 et équipé d'au moins un moyen de préhension 202 par le bras polybenne 301 .  To do this, the support interface 200 comprises a transport tray 201 for receiving said module 1 and equipped with at least one gripping means 202 by the polybenne arm 301.
Le plateau de transport 201 est équ ipé d'un chariot 203 monté mobile en translation le long du plateau de transport 201 entre une position de récupération (figure 6) dans laquelle le chariot 203 est située à proximité d'une extrémité du plateau 201 de manière à permettre l'accroche et la récupération du module 1 à transporter et une position de transport dans laquelle le chariot 203 est remonté vers le moyen de préhension 202 par le bras polybenne 301 en vue de tirer le module sur le plateau. The transport plate 201 is equipped with a carriage 203 mounted to move in translation along the transport plate 201 between a position of recovery (Figure 6) wherein the carriage 203 is located near an end of the plate 201 so as to allow the hooking and recovery of the module 1 to be transported and a transport position in which the carriage 203 is raised to the gripping means 202 by the polybenne arm 301 for pulling the module on the plate.
La figure 7 illustre le fonctionnement de l'interface support 200 en position intermédiaire pour récupérer dans l'eau un module 1 selon l'invention au niveau d'un quai à bord franc.  FIG. 7 illustrates the operation of the support interface 200 in the intermediate position for recovering a module 1 according to the invention from the water at a pier with a freeboard.
Comme précédemment mentionné, l'interface support 200 proposée permet de s'affranchir du type de berge et permet notamment un chargement et déchargement du module 1 même sur des berges à bord franc.  As previously mentioned, the proposed support interface 200 makes it possible to dispense with the type of bank and notably allows loading and unloading of the module 1 even on banks with a freeboard.
Alternativement, dans le cas de quais à bord franc moins élevés, il est possible de se dispenser de l'interface support et d'effectuer une mise à l'eau et récupération à l'aide d'un bras polybenne télescopique.  Alternatively, in the case of lower freeboard docks, it is possible to dispense with the support interface and perform a launching and recovery using a telescopic polybenne arm.
Bien évidemment, le bras polybenne est également utilisable directement où à travers son interface support pour charger ou débarquer un module 1 en l'absence de bord franc, sur une berge à pente douce, notamment une plage. Dans un tel cas, on pourra également envisager une mise à l'eau et une récupération directe du module en descendant l'arriére du camion jusqu'au niveau de l'eau.  Obviously, the polybenne arm can also be used directly or through its support interface to load or unload a module 1 in the absence of free edge, on a gently sloping bank, including a beach. In such a case, we can also consider launching and direct recovery of the module down the back of the truck to the water level.
Selon des caractéristiques additionnelles avantageuses, le module 1 sera conçu de manière à être insubmersible à vide. Il pourra être également rendu pe u sen s i bl e a ux ti rs d ' a rm e l ég è res en prévoya nt u n multi compartimentage des parois et du fond ainsi que compartimentage du flotteur d'étrave. De plus le module pourra être équipé de puissantes pompes de cale.  According to additional advantageous features, the module 1 will be designed so as to be insubmersible when empty. It may also be made available to airmen by means of multi-compartmental walls and bottoms as well as subdivision of the bow float. In addition the module can be equipped with powerful bilge pumps.
Des modules 1 peuvent également être utilisés pour la mise en œuvre d ' u n pon cea u . Pou r ce fa i re, on uti l isera u n prem ier mod u le 1 simplement ouvert mais non déployé, et un deuxième module 1 ouvert et dont la travure 10 aura été déployée comme expliqué précédemment.  Modules 1 can also be used for the implementation of a method. For this purpose, we will use a first mod ule 1 simply open but not deployed, and a second module 1 open and whose span 10 has been deployed as explained above.
Les deux modules 1 seront posés à terre, disposés l'un à côté de l'autre, le plus près possible et sensiblement parallèlement.  The two modules 1 will be placed on the ground, arranged next to each other, as close as possible and substantially parallel.
La travure 10 du deuxième module est déployée et s'étend donc en travers de l'ensemble. Les éléments de rampe stockées dans le premier module 1 et les éléments de rampe du deuxième module 1 sont mis en place aux extrémités de travure. Les moyens de fixation de la travure 10 au vérin télescopique de son module 1 sont démontés. The span 10 of the second module is deployed and therefore extends across the assembly. The ramp elements stored in the first module 1 and the ramp elements of the second module 1 are put in place at the ends of the span. The means for fixing the span 10 to the telescopic jack of its module 1 are dismounted.
Ainsi le ponceau est constitué d'une travure 10 formant voie de roulement et de ses rampes d'extrémités et est désolidarisé des caissons de flottaison 2.  Thus the culvert is made of a spur 10 forming a raceway and its end ramps and is separated from the buoyancy chambers 2.
Ainsi assemblé, le ponceau ponceau pourra être porté au niveau du fossé à franchir par le camion de transport 300 tel que précédemment décrit.  Thus assembled, the culvert culvert can be carried at the level of the ditch to be crossed by the transport truck 300 as previously described.
En fonction de la masse à faire passer sur le ponceau, il sera possible d'adpter l'ensemble en n'utilisant que les rampes et non plus la travure 10 de manière à former un ponceau légèrement plus court mais présentant une résistance à la flexion accrue.  Depending on the mass to be passed on the culvert, it will be possible to adpter the assembly using only the ramps and not the span 10 so as to form a slightly shorter culvert but having a resistance to bending increased.
Les rampes de part et d'autre de la travure 10 permettront l'appui du ponceau sur les bords du fossé et le passage des véhicules.  The ramps on either side of the span 10 will support the culvert on the edges of the ditch and the passage of vehicles.
Bien que l'invention ait été décrite avec un exemple particulier de réal isation, il est bien évident qu'elle n'y est nullement limitée et qu'elle comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci entrent dans le cadre de l'invention.  Although the invention has been described with a particular example of real isation, it is obvious that it is in no way limited and that it includes all the technical equivalents of the means described and their combinations if they enter in the context of the invention.
