Description
L'invention concerne un bloc de carapace en béton moulé monobloc pour structure de protection des ouvrages maritimes et fluviaux contre les vagues et les courants, et un moule pour la réalisation d'un tel bloc.The invention relates to a concrete shell block one-piece molded structure for protecting structures sea and river against waves and currents, and a mold for the production of such a block.
Les caractéristiques techniques recherchées en matière de blocs artificiels sont d'une part la stabilité hydraulique et d'autre part la robustesse.The technical characteristics sought in terms of of artificial blocks are on the one hand the stability hydraulic and on the other hand robustness.
Outre ces caractéristiques techniques, le but des concepteurs de blocs est de diminuer le volume de béton nécessaire pour une carapace donnée tout ayant une stabilité et une robustesse en accord avec leur utilisation. Pour cela les concepteurs jouent sur les dimensions, et les angles des parties constitutives du bloc afin d'augmenter le volume des espaces vides entre blocs imbriqués.In addition to these technical characteristics, the purpose of block designers is to decrease the volume of concrete necessary for a given shell while having stability and robustness in accordance with their use. For it designers play on the dimensions and angles of component parts of the block in order to increase the volume of empty spaces between nested blocks.
La tendance des concepteurs est de modifier les dimensions et les formes générales des pattes ou enclumes constitutives du bloc de manière à générer une forte imbrication tout en ayant plus d'espaces vides dans les imbriquements de blocs. A cet égard on pourra comparer le bloc du document US-A-4347017 datant des années 80, avec le bloc plus élancé du document US-A-5441362 plus récent. En outre, dans le but de réduire le volume de béton sur chaque bloc, les formes des blocs sont élancées.The tendency of designers is to modify dimensions and general shapes of legs or anvils constitutive of the block so as to generate a strong nesting while having more empty spaces in them nested blocks. In this regard we can compare the Document block US-A-4347017 from the 80s, with the more slender block from the more recent document US-A-5441362. In in addition, in order to reduce the volume of concrete on each block, the shapes of the blocks are slender.
Cela a pour conséquence de fragiliser les pattes des blocs qui sont alors plus longilignes.This has the effect of weakening the legs of blocks which are then more elongated.
Les blocs résultant donnent un résultat d'économie de béton non négligeable. Cependant ils sont moins robuste et de ce fait, à terme, il peut apparaítre dans la carapace un défaut de recouvrement occasionnant , dû aux blocs brisés se tassant, mettant à découvert une partie des ouvrages maritimes et fluviaux et pouvant être à l'origine de dommages. The resulting blocks give a saving result of significant concrete. However they are less robust and therefore, ultimately, it may appear in the shell a resulting recovery failure, due to broken blocks tamping, exposing part of the works maritime and fluvial and which can be at the origin of damage.
NL-A-8903138 concerne un bloc de carapace en béton moulé. Le but que se propose d'atteindre ce document est de compenser la fragilité des blocs par un dispositif visant à diminuer la force de collision maximale exercée sur un bloc par les autres blocs l'entourant.NL-A-8903138 relates to a concrete shell block mold. The purpose of this document is to compensate for the fragility of the blocks by a device aimed at decrease the maximum collision force exerted on a block by the other blocks surrounding it.
La solution proposée est de pourvoir le bloc de carapace en béton moulé d'une couche superficielle, en asphalte, en caoutchouc, ou encore en composite ciment-caoutchouc, de rigidité inférieure au bloc de carapace. Ainsi les chocs entre blocs sont amortis.The proposed solution is to provide the block of shell made of molded concrete with a surface layer, asphalt, rubber, or cement-rubber composite, less rigid than the shell block. Thus the shocks between blocks are absorbed.
Il est en outre précisé que cette couche superficielle peut avantageusement, et pour le même but, présenter des saillies ou arrêtes faites de bois, de caoutchouc ou de béton pour rendre la couche superficielle moins rigide que le bloc qu'elle recouvre.It is further specified that this surface layer can advantageously, and for the same purpose, present protrusions or edges made of wood, rubber or concrete to make the surface layer less rigid than the block it covers.
Cependant, les formes de saillies et arrêtes proposées sont géométriquement régulières.However, the forms of protrusions and edges proposed are geometrically regular.
L'axe de réflexion ayant menée à la présente invention est très différent. Il repose sur une amélioration sensible de l'accrochage des bloc entre eux de manière à améliorer le coefficient hydraulique de la carapace et donc limiter les mouvements et les chocs entre blocs.The axis of reflection that led to the present invention is very different. It is based on a significant improvement of the hanging of the blocks together so as to improve the hydraulic coefficient of the shell and therefore limit the movements and shocks between blocks.
L'un des buts de la présente invention est donc de conserver les rapports dimensionnels optimaux des blocs existants et de réaliser sur les surfaces de blocs un relief accidenté irrégulier, sans influence sur la résistance structurelle, constituant une pluralité d'aspérités. Ainsi, sans affaiblir la résistance structurelle des blocs, on obtient une amélioration isotropique de l'accrochage.One of the aims of the present invention is therefore to keep the optimal dimensional ratios of the blocks existing and make a relief on the block surfaces irregular accident, without influence on the resistance structural, constituting a plurality of asperities. So, without weakening the structural strength of the blocks, we obtains an isotropic improvement in attachment.
A cet égard, la présente invention s'oppose complètement à l'idée générale selon laquelle en vue d'en faciliter la fabrication, et notamment le démoulage, les blocs de carapace en béton moulé monobloc doivent présenter une peau extérieure lisse provenant de moulage, avec éventuellement, comme dans NL-A-8903138 une couche superficielle rajoutée. In this regard, the present invention is opposed completely to the general idea that in order to facilitate manufacturing, and in particular demolding, One-piece molded concrete shell blocks must have a smooth outer skin from molding, with possibly, as in NL-A-8903138 a layer superficial added.
En outre le caractère régulier des saillies et arrêtes amortisseurs rajoutées proposées dans NL-A-8903138 va à l'opposé du caractère isotropique d'accrochage des blocs selon l'invention.In addition, the regularity of the projections and edges added shock absorbers proposed in NL-A-8903138 goes to the opposite of the isotropic blocking character of the blocks according to the invention.
l'invention concerne donc un bloc de carapace en béton moulé monobloc pour structure de protection des ouvrages maritimes et fluviaux ayant une surface extérieure de forme générale définissant un polyèdre lisse. Selon l'invention au moins une partie de la surface extérieure du bloc présente des protubérances et/ou des gorges moulés dans la masse du bloc, les protubérances et/ou les gorges présentant des faces dans des plans sécants au plan général local du polyèdre lisse, ces les protubérances et/ou les gorges formant ensemble un relief accidenté irrégulier.the invention therefore relates to a concrete shell block one-piece molded structure for protecting structures maritime and inland waterways with a shaped outer surface general defining a smooth polyhedron. According to the invention in minus part of the outer surface of the block present protrusions and / or grooves molded in the mass of the block, protrusions and / or grooves having faces in secant planes at the general local level of the smooth polyhedron, these protrusions and / or grooves together forming an irregular hilly relief.
Le relief accidenté irrégulier permet d'augmenter le coefficient d'accrochage entre blocs dans toutes les directions (isotropique), et donc d'élever le coefficient de stabilité hydraulique. Le coefficient d'accrochage étant augmenté, l'inertie élémentaire du bloc (masse de béton pour un bloc) peut être réduite, la diminution de la masse de chaque bloc étant compensé par le meilleur accrochage entre blocs. Cela permet une économie de béton sur la réalisation d'une surface donnée de carapace.The irregular uneven relief increases the blocking coefficient between blocks in all directions (isotropic), and therefore to raise the coefficient of hydraulic stability. The hanging coefficient being increased, the elementary inertia of the block (mass of concrete for a block) can be reduced, the decrease in the mass of each block being compensated by the best attachment between blocks. This saves concrete on completion of a given shell surface.
Les faces des protubérances et/ou des gorges sont autant de plans secondaires d'orientations différentes qui multiplient les possibilités de contact plan à plan stabilisé entre blocs par rapport aux surfaces lisses de l'art antérieur.The faces of the protrusions and / or grooves are as many secondary plans of different orientations which increase the possibilities of plan-to-plan contact stabilized between blocks with respect to the smooth surfaces of prior art.
La multiplication des possibilités de contact stabilisé plan à plan entre blocs induit une augmentation du volume des espaces vides inter-bloc.The multiplication of contact possibilities stabilized plane to plane between blocks induces an increase in volume of empty inter-block spaces.
En outre les protubérances et/ou gorges étant moulées dans la masse, la résistance mécanique du bloc est conservé, et les aspérités résultantes présentent une résistance au cisaillement bien supérieure à des aspérités venant en couche superficielle rapportée. In addition the protrusions and / or grooves being molded in the mass, the mechanical strength of the block is preserved, and the resulting asperities show resistance to much greater shear than roughness coming in added surface layer.
De ce fait, avec un même nombre de blocs on obtient une carapace de plus grande surface tout en conservant un effet de groupe équivalent à l'art antérieur.Therefore, with the same number of blocks we get a shell of larger surface area while retaining a group effect equivalent to the prior art.
Les critères environnementaux imposent, de plus en plus, que les ouvrages artificiels s'intègrent au mieux dans le cadre naturel du lieu où ils sont installés. A cet égard les blocs de carapace en béton moulé monobloc à peau lisse ne répondent pas à ces critères et dénaturent les sites où ils sont utilisés. Sur ces chantiers il est alors nécessaire d'utiliser des enrochements naturels issus de carrière. Or l'ouverture de carrières est, elle aussi, sévèrement réglementée et le transport d'enrochements naturels de taille adaptée est source de nuisance (circulation, bruit, pollution, mise en place d'infrastructure d'accès etc...).Environmental criteria increasingly impose more, that artificial works are best integrated into the natural setting of the place where they are installed. In this regard one-piece molded concrete shell blocks with smooth skin do not meet these criteria and distort the sites where they are used. On these sites it is then necessary to use natural riprap from quarries. Gold the opening of quarries is also severely regulated and transport of natural riprap from suitable size is a nuisance (traffic, noise, pollution, installation of access infrastructure etc ...).
C'est donc un autre but de la présente invention de proposer des blocs de carapace en béton moulé monobloc selon l'invention ayant des protubérances et/ou des gorges, provenant de moulage, de forme générale semblable à la forme générale des aspérités naturelles du type de roche du site où ils sont installés (géomorphisme).It is therefore another object of the present invention to offer one-piece molded concrete shell blocks according to the invention having protuberances and / or grooves, from molding, generally similar in shape general natural roughness of the rock type of the site where they are installed (geomorphism).
A cet effet l'invention concerne un bloc de carapace en béton moulé monobloc ayant des protubérances et/ou des gorges, provenant de moulage, disposé dans un lieu ayant un géomorphisme donné. Selon l'invention les protubérances et/ou des gorges, provenant de moulage, présentent un géomorphisme général sensiblement équivalent au géomorphisme des aspérités du lieu considéré.To this end, the invention relates to a shell block in one-piece molded concrete having protuberances and / or grooves, coming from molding, arranged in a place having a given geomorphism. According to the invention the protrusions and / or grooves, originating from molding, have a general geomorphism substantially equivalent to geomorphism roughness of the place considered.
Outre les avantages généraux des blocs selon l'invention, le bloc ayant cette caractéristique a pour avantage de remplacer l'enrochement naturel sans détériorer le site, et en limitant les contraintes liées à la fourniture et à l'acheminement des enrochements naturels vers le site.Besides the general advantages of blocks according to the invention, the block having this characteristic has for advantage of replacing natural riprap without deteriorating the site, and by limiting the constraints linked to the supply and delivery of natural riprap to the site.
Avantageusement le béton constitutif du bloc pourra être coloré dans les tons du milieu géologique du lieu considéré. Advantageously, the concrete constituting the block may be colored in the tones of the geological environment of the place considered.
L'invention concerne aussi un moule pour réaliser un bloc selon l'invention.The invention also relates to a mold for making a block according to the invention.
D'autres avantages et caractéristiques de la présente invention résulteront de la description qui va suivre en référence aux dessins annexés dans lesquels :Other advantages and features of this invention will result from the description which follows reference to the accompanying drawings in which:
Les figures 1A à 1C sont des vues schématiques d'un bloc selon l'invention.Figures 1A to 1C are schematic views of a block according to the invention.

Les blocs proposés en exemple sont des blocs ayant pour polyèdre lisse la forme des blocs de US-A-4347017 cependant ces exemples destinés à illustration la description ne sont nullement limitatifs du type de base des blocs selon l'invention.The blocks offered as an example are blocks having for smooth polyhedron the shape of the blocks from US-A-4347017 however these examples intended to illustrate the description are in no way limitative of the basic type of blocks according to the invention.
L'invention concerne un bloc 1 de carapace en béton
moulé monobloc pour structure de protection des ouvrages
maritimes et fluviaux.The invention relates to a
Ce bloc 1 est constitués de pattes 2 agencées ensemble
selon des angles et des écarts inter-patte donnés.This
Ce bloc 1 a une surface extérieure 6 de profil général
définissant un polyèdre lisse 3. On appelle polyèdre lisse 3
la surface lissée du profil extérieur du bloc. Dans l'art
antérieur ce polyèdre lisse correspond à la surface
extérieure brute de décoffrage du bloc.This
Selon l'invention, au moins une partie de la surface
extérieure 6 présente, par rapport au polyèdre lisse 3, des
protubérances 4 et/ou des gorges 5 provenant de moulage.According to the invention, at least part of the
Il est clair que les défauts de surface résultant du
décoffrage d'un moule lisse de l'art antérieur ne
constituent pas les protubérances 4 et/ou gorges 5 du bloc 1
selon la présente invention. It is clear that the surface defects resulting from the
formwork of a smooth mold of the prior art does
do not constitute protuberances 4 and / or

Les protubérances 4 et/ou les gorges 5 sont dues à des

ont été rajoutés des éléments protubérants comprenant ou

des gorges 5 et des protubérances 4 sur le bloc 1.Advantageously, the mold (not shown) can be
the smooth mold of the equivalent smooth-skin block in which
have been added protruding elements comprising or
generating between them grooves, so that when the
concrete is poured into the mold, it results, in positive,
Ainsi on comprend bien que, tout en respectant les
proportions optimales d'un bloc lisse équivalent, le volume
élémentaire de béton nécessaire à la réalisation d'un bloc 1
selon l'invention est diminué du volume des éléments
protubérants ajoutés dans le moule, ces éléments
protubérants créant sur le bloc 1 des gorges 5 et de
protubérances 4 venant, du fait de l'augmentation du
coefficient d'accrochage, pallier le défaut de masse
élémentaire du bloc 1 par rapport à son équivalent lisse.So we understand that, while respecting the
optimal proportions of an equivalent smooth block, the volume
elementary concrete necessary for the realization of a

faces constitutives dans des plans sécants au plan local du
polyèdre lisse et forment ensemble un relief accidenté
irrégulier. De ce fait cela augmente considérablement le
nombre de plan dans lesquels les blocs 1 imbriqués sont
susceptibles de se retrouvés en appui stabilisé.
L'imbriquement qui en résulte présente des espaces de vide
inter-blocs plus important qu'avec des blocs à peau lisse
tout en préservant l'effet de groupe de la carapace.These protrusions 4 and / or
Les figures 2A-2D et 3A-3D représentent deux exemples
de blocs selon l'invention sur lesquels les protubérances 4
et/ou les gorges 5 présentent un géomorphisme similaire avec
respectivement un site granitique et un site basaltique. De
cette manière, les blocs selon l'invention s'intègrent dans
leur site de dépôt sans le dénaturer.Figures 2A-2D and 3A-3D show two examples
of blocks according to the invention on which the protrusions 4

Le bloc géomorphique peut être avantageusement teint dans la masse dans un ton semblable aux couleurs géologiques du site dans lequel il est déposé.The geomorphic block can be advantageously dyed in the mass in a tone similar to the geological colors of the site in which it is deposited.
Avantageusement le moule selon la présente invention peut être un moule lisse réhabilité. La réalisation d'un tel moule réhabilité peut comprendre les étapes suivantes :Advantageously, the mold according to the present invention can be a rehabilitated smooth mold. The realization of such rehabilitated mold can include the following steps:
On réalise un bloc lisse homothétique de volume inférieur au volume du moule lisse à réhabiliter, de manière qu'il existe une épaisseur de vide entre le moule à réhabiliter le bloc.We realize a smooth homothetic block of volume less than the volume of the smooth mold to be rehabilitated, so that there is a vacuum thickness between the mold rehabilitate the block.
Dans un premier mode de réalisation, on sculpte directement sur le bloc les protubérances et les gorges; puis on maintien le bloc sculpté centré dans le moule et on coule un matériau moulable entre le bloc sculpté et la paroi lisse du moule. On obtient ainsi un moulage du bloc reproductible, et parfaitement intégrée dans des moules lisses à réhabiliter.In a first embodiment, we sculpt directly on the block the protrusions and the grooves; then we keep the sculpted block centered in the mold and we a moldable material flows between the sculpted block and the wall mold smooth. A block molding is thus obtained reproducible, and perfectly integrated in molds smooth to rehabilitate.
Dans un deuxième mode de réalisation, le bloc lisse est enduit d'une épaisseur de matériau facilement façonnable dans laquelle sont façonnées les protubérances et les gorges; puis on maintien le bloc à couche extérieure façonnée centré dans le moule et on coule un matériau moulable entre le bloc à couche extérieure façonnée et la paroi lisse du moule. On obtient ainsi un moulage du bloc reproductible, et parfaitement intégrée dans des moules lisses à réhabiliter.In a second embodiment, the smooth block is coated with a thickness of easily shaped material in which the protuberances and the grooves; then we maintain the block with an outer layer shaped centered in the mold and a material is poured moldable between the shaped outer layer block and the smooth mold wall. A block molding is thus obtained reproducible, and perfectly integrated in molds smooth to rehabilitate.
Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés, mais elle est susceptible de nombreuses variantes accessibles à l'homme du métier sans que l'on s'écarte de l'invention comme définie dans les revendications. En particulier, on pourra, sans sortir du cadre de l'invention, remplacer le bloc de base lisse par tout autre bloc connu. De même on pourra, sans sortir du cadre de l'invention, décliner des blocs ayant des géomorphismes semblables à d'autres géomorphismes naturels que granitique ou basaltique.Of course, the invention is not limited to the modes described and represented, but it is susceptible of numerous variants accessible to the man of the profession without departing from the invention as defined in the claims. In particular, without departing from the scope of the invention, replace the smooth base block with any other known block. Likewise, without departing from the scope of the invention, decline blocks with geomorphisms similar to other natural geomorphisms than granitic or basaltic.
