Abstract

The caisson has a panel (1) made of a composite material which is divided into ballast compartments (17) by an internal framework. This is surrounded by a frame (2) which encloses the bottom (1) and sides (12) of the panel (1). The frame acts as ballast at the lower edge of the panel and forms a rigid support at the entrance of the dry dock. The frame is the same size as the panel where they join. The frame is made of concrete reinforced with fibreglass strips. The panel is attached to it with bolts and threaded rods (3) anchored in the concrete. The concrete in the upper section has less voluminal mass than that in the lower part. The side walls (2b) are become thinner as they reach the top, also reducing the mass. The panel is made of a composite glass and resin material with transverse stiffeners (16). The panel is made of many caissons which are glued together with a layer of glass and resin composite on the side walls Made of composite materials which are resistant to corrosion from seawater. Caisson has good mechanical resistance, is simple to construct and narrower and less expensive <IMAGE>

Description

La présente invention concerne des bateaux-portes dont la fonction est d'assurer la fermeture étanche des entrées de bassins de radoub donnant sur la mer, pour permettre la mise en cale sèche de navires.The present invention relates to door-boats whose function is to ensure the watertight closing of the entrances to dry docks overlooking the sea, to allow the dry docking of ships.

Pour l'essentiel, un bateau-porte est constitué d'une enveloppe extérieure et d'une ossature interne raidissant l'ensemble et le divisant en compartiments dont la plupart sont des ballasts. Le long de son fond et de ses côtés, l'enveloppe présente une surface d'appui avec joint d'étanchéité, destinée à venir s'appliquer contre la maçonnerie de l'entrée de bassin à obturer. Un lest est généralement prévu dans les fonds, et un système de pompage et de vidange permet de remplir ou vider sélectivement les différents ballasts.For the most part, a door boat consists of an outer envelope and an internal framework stiffening the assembly and dividing it into compartments, most of which are ballasts. Along its bottom and its sides, the envelope has a bearing surface with seal, intended to be applied against the masonry of the basin entrance to be closed. A ballast is generally provided in the bottoms, and a pumping and emptying system makes it possible to selectively fill or empty the different ballasts.

La forme, la masse, la stabilité, l'agencement des ballasts et leurs volumes sont déterminés de manière à ce que le bateau-porte soit susceptible aussi bien de flotter librement avec des tirants d'eau variables, que de reposer sur le fond et d'obturer l'entrée d'un bassin, avec une flottabilité négative (prépondérance de coulée sécuritaire). Lorsque le bassin est vide, le maintien en place du bateau-porte est assuré par la seule pression de l'eau, côté mer.The shape, mass, stability, arrangement of the ballasts and their volumes are determined in such a way that the carrier boat is as likely to float freely with variable drafts, as to rest on the bottom and to seal the entrance to a basin, with negative buoyancy (preponderance of safe casting). When the tank is empty, the door-boat is held in place by the only pressure of the water, sea side.

Depuis toujours, les bateaux-portes ont été réalisés en tôles d'acier rivées, ou soudées pour les plus récents. Leurs formes et dimensions sont déduites des différentes conditions de flottabilité. Ainsi ont-ils en règle générale une partie inférieure ventrue par rapport à une partie supérieure moins large en vue d'alléger l'ensemble et d'obtenir des caractéristiques de stabilité acceptables.Door-boats have always been made of riveted steel sheets, or welded for the most recent. Their shapes and dimensions are deduced from the different buoyancy conditions. Thus, as a rule, they have a bulging lower part with respect to a narrower upper part. to lighten the assembly and obtain acceptable stability characteristics.

L'inconvénient majeur de ces bateaux-portes réside dans le fait qu'étant soumis sans cesse à des immersions-émersions alternées, ils sont l'objet d'une forte corrosion marine qui rend nécessaires, tant à l'intérieur qu'à l'extérieur, des opérations d'entretien et de traitement de surface régulières et onéreuses.The major drawback of these door-boats lies in the fact that, being constantly subjected to alternating immersion-emersion, they are subject to strong marine corrosion which makes it necessary, both inside and outside. exterior, regular and expensive surface maintenance and treatment operations.

L'invention a été réalisée dans le but de pallier cet inconvénient en prévoyant de faire appel, pour la construction de bateaux-portes, à des matériaux composites , par exemple de type fibre de verre-résine, qui ont l'avantage d'être insensibles à la corrosion marine.The invention was carried out with the aim of overcoming this drawback by providing for the use, for the construction of door-boats, of composite materials, for example of the fiberglass-resin type, which have the advantage of being insensitive to marine corrosion.

Un autre but recherché a été de concevoir une nouvelle architecture de bateau-porte adaptée à l'utilisation de matériau composite qui, tout en satisfaisant à l'ensemble des exigences techniques, notamment de résistance mécanique, soit de forme et de construction simples et de largeur réduite, et donc de moindre coût.Another sought-after goal was to design a new door-boat architecture adapted to the use of composite material which, while satisfying all the technical requirements, in particular of mechanical resistance, either of simple shape and construction and of reduced width, and therefore lower cost.

A cet effet, l'invention consiste en un bateau-porte servant à obturer l'entrée d'un bassin de radoub, caractérisé en ce qu'il comprend deux parties distinctes :

  • une enveloppe en matériau composite ayant une forme générale de parallélépipède rectangle ou de prisme droit à parois longitudinales trapézoïdales, divisée intérieurement par une ossature interne en une pluralité de compartiments-ballasts,
  • un cadre venant border ladite enveloppe le long de son fond et de ses côtés latéraux, en un matériau aux densités et caractéristiques mécaniques appropriées pour, d'une part, exercer une fonction de lest au niveau de la partie inférieure de l'enveloppe et, d'autre part, constituer un appui rigide destiné à venir s'appliquer contre la maçonnerie de l'entrée du bassin,

   l'enveloppe et le cadre étant assemblés l'un à l'autre par des moyens de fixation.To this end, the invention consists of a door boat used to close off the entrance to a refit basin, characterized in that it comprises two separate parts:
  • an envelope of composite material having a general shape of a rectangular parallelepiped or of a straight prism with trapezoidal longitudinal walls, internally divided by an internal framework into a plurality of ballast compartments,
  • a frame bordering said envelope along its bottom and its lateral sides, made of a material at the appropriate mechanical densities and characteristics to, on the one hand, exert a ballast function at the level of the lower part of the envelope and, on the other hand, constitute a rigid support intended to be applied against the masonry of entrance to the pool,

the envelope and the frame being assembled to each other by fixing means.

Cette architecture en deux parties permet de réaliser l'enveloppe et le cadre indépendamment l'un de l'autre pour ne les assembler qu'ensuite. Elle autorise également une forme d'enveloppe simplifiée à l'extrême qui facilite grandement la construction en matériau composite, seul le cadre étant soumis à des contraintes de forme pour constituer l'appui contre la maçonnerie de l'entrée du bassin auquel le bateau-porte est destiné.This architecture in two parts makes it possible to produce the envelope and the frame independently of one another so as to assemble them only afterwards. It also allows an extremely simplified envelope form which greatly facilitates construction in composite material, only the frame being subjected to form constraints to constitute the support against the masonry of the entrance to the basin to which the boat- door is intended.

De façon avantageuse, le cadre est prévu en béton, au moins en ce qui concerne sa partie inférieure à fonction de lest. La fixation de l'enveloppe et des parties en béton du cadre est réalisée par boulonnage sur des tiges filetées ancrées dans le béton.Advantageously, the frame is provided in concrete, at least as far as its lower part is ballasted. The envelope and the concrete parts of the frame are fixed by bolting on threaded rods anchored in the concrete.

Dans une forme de réalisation préférée, le cadre a un profil sensiblement de même largeur que l'enveloppe au niveau de la jonction avec celle-ci. Il recouvre donc entièrement l'enveloppe le long du fond et des deux côtés latéraux, en apportant ses propriétés mécaniques, et notamment sa rigidité, à l'ensemble.In a preferred embodiment, the frame has a profile substantially the same width as the envelope at the junction with it. It therefore completely covers the envelope along the bottom and on the two lateral sides, providing its mechanical properties, and in particular its rigidity, to the assembly.

Ces caractéristiques et avantages de l'invention, ainsi que d'autres, apparaîtront plus clairement dans la description suivante, faite en relation avec les dessins annexés, dans lesquels :

  • la Fig. 1 est une coupe verticale longitudinale d'une forme de réalisation de bateau-porte selon l'invention,
  • la Fig. 2 est une demi-coupe horizontale selon la ligne II-II de la Fig. 1,
  • la Fig. 3 est une coupe verticale transversale selon la ligne III-III de la Fig.1, et
  • la Fig. 4 est une vue en coupe horizontale du détail A de la Fig. 2.
These characteristics and advantages of the invention, as well as others, will appear more clearly in the following description, given in conjunction with the appended drawings, in which:
  • Fig. 1 is a longitudinal vertical section of an embodiment of a door-boat according to the invention,
  • Fig. 2 is a horizontal half-section along line II-II of FIG. 1,
  • Fig. 3 is a vertical transverse section along line III-III of FIG. 1, and
  • Fig. 4 is a view in horizontal section of the detail A of FIG. 2.

Vu de front, le bateau-porte représenté sur les dessins a une forme générale trapézoïdale qui correspond à celle de la feuillure en maçonnerie de l'entrée du bassin auquel il est destiné. Il s'agit là d'une forme habituelle due au fait que les parois latérales des bassins de radoub sont le plus souvent étagées, et que la feuillure suit alors leur ligne de pente.Seen from the front, the door boat shown in the drawings has a general trapezoidal shape which corresponds to that of the masonry rebate at the entrance to the basin for which it is intended. This is a usual form due to the fact that the side walls of the refit basins are most often stepped, and the rebate then follows their line of slope.

Selon l'invention, cette forme trapézoïdale du bateau-porte est réalisée au niveau du pourtour extérieur d'un cadre 2 qui borde le corps proprement dit du bateau le long de son fond et de ses deux côtés latéraux. Intérieurement, le cadre présente deux faces planes verticales 21 de chaque côté d'une face de base horizontale 20 également plane, de manière à recevoir en tant que corps du bateau une enveloppe 1 en forme de parallélépipède rectangle. En variante, l'enveloppe 1 peut être prismatique, avec des parois longitudinales 13 en forme de trapèze isocèle, pour éviter d'élargir les côtés du cadre vers le haut.According to the invention, this trapezoidal shape of the door-boat is produced at the outer periphery of a frame 2 which borders the body of the boat itself along its bottom and on its two lateral sides. Internally, the frame has two vertical planar faces 21 on each side of a horizontal base face 20 also planar, so as to receive as the body of the boat an envelope 1 in the form of a rectangular parallelepiped. As a variant, the envelope 1 can be prismatic, with longitudinal walls 13 in the form of an isosceles trapezoid, to avoid widening the sides of the frame upwards.

L'enveloppe 1 est réalisée entièrement en matériau composite, avantageusement de type fibre de verre-résine (CVR). Ses parois de fond 10, de dessus 11, latérales 12 et longitudinales 13 définissent un volume intérieur divisé en compartiments 17 par un ensemble de plates-formes horizontales 14 et de cloisons verticales 15. Les compartiments sont en majorité des ballasts, les autres logeant les organes tels que pompes 18, Fig. 1, servant au fonctionnement du bateau-porte.The casing 1 is made entirely of composite material, advantageously of the fiberglass-resin (CVR) type. Its bottom 10, top 11, side 12 and longitudinal 13 walls define a volume interior divided into compartments 17 by a set of horizontal platforms 14 and vertical partitions 15. The compartments are for the most part ballasts, the others housing the members such as pumps 18, FIG. 1, used for the operation of the door boat.

Les plates-formes 14 et cloisons 15 constituent d'autre part une ossature ayant pour fonction de contribuer à la rigidité de l'enveloppe 1. Des raidisseurs transversaux 16 sont rapportés sur les plates-formes 14 et intérieurement sur les parois de base 10 et de dessus 11 de l'enveloppe 1.The platforms 14 and partitions 15 on the other hand constitute a framework having the function of contributing to the rigidity of the envelope 1. Transversal stiffeners 16 are attached to the platforms 14 and internally on the base walls 10 and top 11 of envelope 1.

L'utilisation de matériau composite pour réaliser l'enveloppe 1 se traduit par un gain de masse global important comparé à une construction en acier. Par ailleurs, les parois consistant en une superposition de plis, il est aisé de moduler le nombre des plis et par conséquent l'épaisseur et la masse surfacique, entre les différentes parois, et même entre plusieurs zones d'une même paroi, en fonction leur position dans l'enveloppe qui nécessite plus de résistance dans sa partie inférieure que dans sa partie supérieure. Ainsi, les parois 10 à 13 de l'enveloppe, les plates-formes 14 et les cloisons 15 pourront-elles être de moins en moins épaisses de bas en haut. L'enveloppe 1 sera donc allégée dans sa partie supérieure où elle est le moins sollicitée, mais aussi où la masse est pénalisante pour la stabilité.The use of composite material to produce the casing 1 results in a significant overall weight gain compared to a steel construction. Furthermore, the walls consisting of a superposition of folds, it is easy to modulate the number of folds and therefore the thickness and the surface mass, between the different walls, and even between several zones of the same wall, depending their position in the envelope which requires more resistance in its lower part than in its upper part. Thus, the walls 10 to 13 of the envelope, the platforms 14 and the partitions 15 may they be less and less thick from the bottom up. The envelope 1 will therefore be lightened in its upper part where it is least stressed, but also where the mass is detrimental for stability.

La Fig. 3 fait apparaître en traits fins des caissons 30 de forme simple qui peuvent être rapportés de part et d'autre de l'enveloppe 1 dans certains cas, notamment lorsque les contraintes de tirant d'eau sont sévères.Fig. 3 shows in fine lines boxes 30 of simple shape which can be attached to either side of the casing 1 in certain cases, in particular when the draft constraints are severe.

Le cadre 2 qui doit accomplir une fonction de lest au niveau de la partie inférieure de l'enveloppe 1 et qui, d'autre part, doit constituer un appui périphérique rigide et indéformable pour assurer la fermeture étanche contre la feuillure de l'entrée de bassin, est dans une forme de réalisation satisfaisante prévu en béton, armé par exemple au moyen de joncs en fibre de verre, qui apporte ses avantages de facilité de mise en oeuvre et d'insensibilité à la corrosion marine comme les matériaux composites.The frame 2 which must perform a ballast function at the level of the lower part of the casing 1 and which, on the other hand, must constitute a rigid and non-deformable peripheral support to ensure the tight closure against the rebate of the entry of basin, is in a satisfactory embodiment provided in concrete, reinforced for example by means of fiberglass rods, which brings its advantages of ease of implementation and of insensitivity to marine corrosion like composite materials.

Le cadre 2 a une section droite symétrique par rapport à un axe médian normal au côté correspondant à la face interne 20 ou 21. A partir de cette face interne 20 ou 21, le corps du profilé présente une largeur constante, sensiblement égale à celle de l'enveloppe 1 sur une certaine distance d, Fig. 3. Ensuite, la largeur diminue jusqu'à la naissance d'une aile périphérique 22 qui constitue l'appui de fermeture et d'étanchéité du cadre. La face d'appui de l'aile 22 est pourvue d'un joint en élastomère 23.The frame 2 has a cross section symmetrical with respect to a median axis normal to the side corresponding to the internal face 20 or 21. From this internal face 20 or 21, the body of the profile has a constant width, substantially equal to that of the envelope 1 over a certain distance d, FIG. 3. Then, the width decreases until the birth of a peripheral wing 22 which constitutes the support for closing and sealing the frame. The bearing face of the wing 22 is provided with an elastomer seal 23.

La distance d est constante le long de la partie de base horizontale 2a du cadre 2, où elle est notamment fonction de la masse de lest désirée. Par contre, elle augmente linéairement de bas en haut sur la longueur des montants 2b du cadre, en raison de la forme évasée en trapèze de l'appui périphérique 22. Pour amoindrir la masse du cadre en partie supérieure, on peut néanmoins prévoir un profil évolutif des montants 2b, tendant par exemple vers la forme schématisée par les traits-tirets 24 à la Fig. 2. En variante ou en complément, on peut incorporer dans le béton de la partie supérieure des montants un composant de charge de faible masse volumique. Il serait également possible d'utiliser des matériaux différents pour la réalisation de la base 2a d'une part, et des montants 2b d'autre part.The distance d is constant along the horizontal base part 2a of the frame 2, where it is in particular a function of the desired mass of ballast. On the other hand, it increases linearly from bottom to top along the length of the uprights 2b of the frame, due to the flared, trapezoidal shape of the peripheral support 22. To reduce the mass of the frame in the upper part, it is nevertheless possible to provide a profile evolutionary amounts 2b, tending for example to the form shown schematically by the dashed lines 24 in FIG. 2. As a variant or in addition, a low density load component may be incorporated into the concrete of the upper part of the uprights. It would be also possible to use different materials for the realization of the base 2a on the one hand, and the uprights 2b on the other hand.

A des fins pratiques, le cadre 2 est construit en plusieurs étapes, ou en plusieurs éléments séparés, par exemple la partie de base 2a et les montants 2b qui vont être assemblés ensuite avec l'enveloppe 1. Un mode de fixation entre les parois de fond et d'extrémité de l'enveloppe 1 d'une part, et le cadre d'autre part, apparaît en détail à la Fig. 4 : des tiges métalliques filetées 3 sont ancrées dans le béton du cadre, régulièrement écartées en deux rangées périphériques sur les faces 20, 21 de son pourtour intérieur. Les tiges 3 sont passées dans des trous ménagés dans les parois 10 et 12 de l'enveloppe, puis reçoivent des boulons de serrage. Le repère 4 désigne des plats de serrage, lesquels côté cadre sont noyés dans le béton pour affleurer les surfaces 20, 21 en contact avec les parois de l'enveloppe.For practical purposes, the frame 2 is constructed in several stages, or in several separate elements, for example the base part 2a and the uprights 2b which will then be assembled with the casing 1. A method of fixing between the walls of bottom and end of the casing 1 on the one hand, and the frame on the other hand, appears in detail in FIG. 4: threaded metal rods 3 are anchored in the concrete of the frame, regularly spaced in two peripheral rows on the faces 20, 21 of its inner periphery. The rods 3 are passed through holes in the walls 10 and 12 of the envelope, then receive tightening bolts. The reference 4 designates clamping plates, which on the frame side are embedded in the concrete to be flush with the surfaces 20, 21 in contact with the walls of the envelope.

Dans une réalisation prototype construite selon l'architecture représentée sur les dessins et décrite ci-dessus, qui s'est avérée satisfaisante s'agissant notamment des caractéristiques de stabilité, l'enveloppe 1 d'une longueur d'environ 15 mètres avait une largeur de seulement 1,6 mètre pour une hauteur de 7,5 mètres, le rapport largeur/hauteur étant donc de l'ordre de 0,2.In a prototype embodiment constructed according to the architecture shown in the drawings and described above, which has proved satisfactory with regard in particular to the stability characteristics, the envelope 1 with a length of approximately 15 meters has a width only 1.6 meters for a height of 7.5 meters, the width / height ratio therefore being of the order of 0.2.
