Description

La présente invention concerne un bloc de drainage modulaire destiné à drainer les sols, en général, et autour des bâtiments et habitations, en particulier.The present invention relates to a modular drainage block for draining soils, in general, and around buildings and dwellings, in particular.

La pose d'un système de drainage traditionnel est fastidieux et nécessite des moyens importants et onéreux. La mise en place d'un tel système demande notamment les opérations suivantes : on réalise une tranchée que l'on recouvre d'un tissu géotextile, on déroule au fond de la tranchée un long tuyau de drainage généralement réalisé en PVC et perforé, on recouvre ce tuyau de gravier, on rabat le tissu géotextile puis on remblaie. Ce système présente par conséquent de nombreux inconvénients. Le tissu géotextile a tendance à glisser le long des parois de la tranchée quand on déverse le gravier et il se retrouve fréquemment sous le gravier. Le tuyau de drainage a tendance à remonter dans la tranchée en raison de sa rigidité et des vibrations engendrées lors du déversement du gravier. Lorsque les températures sont inférieures à -10°C, le tuyau en PVC devient cassant. De plus, ce tuyau de drainage est difficilement maniable. Il est, par conséquent, difficile de poser seul ce type de drainage et son coût de réalisation est élevé compte tenu du gravier à approvisionner et à transporter, et de la main d'oeuvre nécessaire.The installation of a traditional drainage system is tedious and requires important and expensive. The establishment of such a system requires, in particular, following operations: a trench is made which is covered with a geotextile fabric, at the bottom of the trench, a long drainage pipe, usually PVC and perforated, we cover this gravel pipe, we fold the geotextile fabric and then we backfilled. This system therefore has many disadvantages. The fabric geotextile tends to slide along the walls of the trench when we dump the gravel and it is frequently found under gravel. The drainage pipe has tendency to climb back into the trench due to rigidity and vibrations generated during the discharge of gravel. When temperatures are lower at -10 ° C, the PVC pipe becomes brittle. In addition, this drain pipe is difficult to handle. It is therefore difficult to pose alone this type of drainage and its cost of realization is high considering the gravel to supply and to transport, and the necessary manpower.

Certaines solutions ont été élaborées dans le but de résoudre une partie de ces problèmes. La publication FR-A-2 420 071 décrit un tube de drainage comportant en périphérie extérieure des nervures ou des plots formant entre eux des passages de ruissellement qui communiquent avec l'intérieur du tube par des trous. Ce tube est entouré d'une laine géotextile et peut être posé directement au fond d'une tranchée avant d'être recouvert de remblais. Il a l'inconvénient majeur d'avoir une surface de captage des eaux de drainage limitée à la surface périphérique du tube lui-même, ce qui peut s'avérer nettement insuffisant. La publication DE-A-22 07 216 décrit un bloc de drainage monobloc de section carrée, traversé par un conduit collecteur central et longitudinal. Il est réalisé dans une matière granuleuse offrant des passages très restreints pour les eaux de drainage, ne permettant pas, de ce fait, un drainage efficace. De plus, aucun dispositif n'est prévu pour diriger les eaux de drainage en direction du conduit collecteur, de ce fait une partie s'évacue dans le remblai. La publication US-A-3 440 823 décrit un dispositif de drainage comportant deux pièces distinctes : un conduit de drainage en forme de V inversé posé sur une semelle imperméable. Le conduit ne comporte que très peu de canaux latéraux prévus sur les bords du V, nettement insuffisants pour capter les eaux de drainage. De plus, cette forme en V inversé n'offre pas une résistance suffisante à l'écrasement dû au poids des remblais. Enfin, la publication NL-A-7 211 660 décrit un bloc de drainage traversé par un conduit collecteur central et longitudinal, ce bloc étant limité au captage des eaux pluviales dans un caniveau, étant donné qu'il ne comporte que des ouvertures disposées en partie supérieure.Some solutions have been developed in order to solve some of these problems. Publication FR-A-2 420 071 describes a drainage tube comprising in outer periphery of the ribs or studs forming between them passages of runoff that communicate with the inside of the tube through holes. This tube is surrounded by a geotextile wool and can be placed directly at the bottom of a trench before being covered with embankments. It has the major disadvantage of having a surface of drain water collection limited to the peripheral surface of the tube itself, this which can be clearly insufficient. The publication DE-A-22 07 216 describes a monobloc drainage block of square section, crossed by a collector duct central and longitudinal. It is made of a granular material with passages very restricted for drainage water, thus not permitting drainage effective. In addition, no device is provided to direct drainage water into direction of the collector duct, so a part is evacuated in the embankment. The Publication US-A-3,440,823 discloses a two-piece drainage device separate: an inverted V-shaped drainage channel on a sole raincoat. The duct has only very few lateral channels provided on the edges of the V, clearly insufficient to capture the drainage water. In addition, this inverted V shape does not provide sufficient crush resistance due to weight embankments. Finally, the publication NL-A-7 211 660 describes a drainage block crossed by a central and longitudinal collector duct, this block being limited to capture of rainwater in a gutter, since it contains only openings arranged in the upper part.

Par conséquent, aucun dispositif existant ne permet d'apporter une solution efficace, fiable, simple et économique au problème du drainage.Therefore, no existing device can provide an effective solution, reliable, simple and economical to the problem of drainage.

La présente invention vise à apporter cette solution en proposant un bloc de drainage performant, pratique, facile à utiliser et capable de capter et d'évacuer efficacement les eaux de drainage.The present invention aims to provide this solution by proposing a drainage block powerful, practical, easy to use and able to capture and evacuate effectively drainage water.

Selon une variante de réalisation envisageable, les moyens de raccordement peuvent comporter un manchon intégré audit corps, disposé en prolongement d'une des extrémités du conduit collecteur et agencé pour former une partie mâle, l'autre extrémité du conduit collecteur étant agencé pour former une partie femelle destinée à recevoir la partie mâle d'un bloc de drainage adjacent.According to an alternative embodiment that can be envisaged, the connection means can have a sleeve integrated in said body, arranged in extension of one of ends of the collector duct and arranged to form a male part, the other end of the collector duct being arranged to form a female portion for receive the male part of an adjacent drainage block.

D'une manière avantageuse, les moyens de raccordement comportent également au moins une ouverture latérale prévue dans ledit corps au même niveau que ledit conduit collecteur, cette ouverture latérale ayant des dimensions sensiblement égales à celles dudit conduit collecteur, débouchant dans ce dernier, et étant agencée pour recevoir ledit manchon destiné à assembler en angle droit deux blocs de drainage consécutifs.Advantageously, the connection means also comprise the minus a lateral opening provided in said body at the same level as said collector duct, this lateral opening having dimensions substantially equal to those of said collector duct, opening into the latter, and being arranged to receiving said sleeve for assembling at right angles two drainage blocks consecutive.

Selon la forme de réalisation préférée, l'enveloppe extérieure est constituée d'un tissu réalisé dans une matière géotextile, ce tissu étant enroulé autour dudit corps et étant plus long d'un côté de manière à recouvrir partiellement le bloc de drainage suivant.According to the preferred embodiment, the outer shell consists of a fabric made in a geotextile material, this fabric being wrapped around said body and being longer on one side to partially cover the next drainage block.

Le corps peut être réalisé dans une matière imperméable à l'eau choisie parmi le groupe comprenant au moins le polystyrène, le polychlorure de vinyle, le béton, la résine de synthèse et toute matière synthétique moulée ou extrudée.The body may be made of a waterproof material chosen from the group comprising at least polystyrene, polyvinyl chloride, concrete, synthetic resin and any synthetic material molded or extruded.

Le corps peut également être réalisé dans une matière perméable à l'eau choisie parmi le groupe comprenant au moins le polystyrène expansé et toute matière synthétique structurée ou moussée. Dans ce cas, le corps peut comporter une zone étanche disposée en dessous du conduit collecteur et constituée par une semelle en matière imperméable incorporée dans ou sous ledit corps. Le conduit collecteur peut aussi comporter une enveloppe intérieure étanche, si nécessaire.The body may also be made of a water permeable material selected from the group comprising at least expanded polystyrene and any synthetic material structured or foamed. In this case, the body may comprise a sealed zone disposed below the collector duct and constituted by a sole material waterproof incorporated in or under said body. The collector pipe can also have a tight inner envelope, if necessary.

The present invention and its advantages will appear better in the following description of non-exhaustive exemplary embodiments, with reference to the appended drawings, in which:

En référence aux figures 1 à 3, le bloc de drainage modulaire 1 selon l'invention est destiné à drainer les sols, par exemple mais non exclusivement, autour d'une habitation ou d'un bâtiment. Il comporte un corps allongé 2, un conduit collecteur longitudinal 3 traversant le corps de part en part et des passages de ruissellement 5 s'ouvrant sur les parois périphériques supérieure et latérales du corps 2 et débouchant dans le conduit collecteur 3 agencés pour permettre la circulation des eaux de ruissellement par gravité vers ledit conduit. Il comporte encore des moyens de raccordement 6 agencés pour assembler deux blocs de drainage 1 consécutifs et une enveloppe extérieure 7 perméable à l'eau uniquement visible en pointillés sur la figure 1.With reference to FIGS. 1 to 3, the modular drainage block 1 according to the invention is intended to drain soils, for example but not exclusively, around a dwelling or building. It comprises an elongate body 2, a collector duct longitudinal 3 passing through the body from side to side and runoff passages 5 opening on the peripheral walls upper and lateral of the body 2 and opening into the conduit collector 3 arranged to allow the circulation of runoff water by gravity towards said conduit. It also comprises connecting means 6 arranged to assemble two consecutive drainage blocks 1 and an outer envelope 7 permeable to water only visible in dashed lines in FIG.

Le corps allongé 2 doit pouvoir résister à la pression d'une charge de terre. A cet effet, il présente une section polygonale. Sa forme définit au moins une base 20 plane et une paroi latérale 21 plane formant avec ladite base un angle droit permettant de positionner le bloc de drainage modulaire 1 à la base et le long des fondations 9 d'un bâtiment.The elongated body 2 must be able to withstand the pressure of a soil load. In this indeed, it has a polygonal section. Its shape defines at least one flat base and one flat side wall 21 forming with said base a right angle for positioning the drainage block modular 1 at the base and along the foundations 9 of a building.

Ce corps 2 peut être réalisé dans une matière imperméable à l'eau comme par exemple le polystyrène, le polychlorure de vinyle, le béton, la résine de synthèse ou toute autre matière équivalente synthétique ou non, moulée ou extrudée. Il peut être aussi réalisé dans une matière perméable à l'eau comme par exemple le polystyrène expansé plus ou moins dense ou toute autre matière synthétique moussée ou structurée par exemple en nid d'abeille. L'essentiel est que la combinaison de la géométrie de ce corps et de sa matière ou structure lui permette d'offrir une résistance suffisante à la compression pour résister à une charge de terre.This body 2 can be made of a waterproof material such as for example polystyrene, polyvinyl chloride, concrete, synthetic resin or any other synthetic equivalent material or not, molded or extruded. It can also be realized in a water-permeable material such as expanded polystyrene more or less dense or any other foamed or structured synthetic material for example honeycomb. The bottom line is that the combination of the geometry of this body and its material or structure allows it to offer sufficient resistance to compression to resist a load of earth.

Dans le cas d'une matière perméable à l'eau, une zone étanche peut être prévue en dessous du conduit collecteur 3 pour éviter l'écoulement des eaux de drainage dans le sol. Cette zone étanche peut être constituée d'une semelle (non représentée) réalisée dans une matière imperméable incorporée dans ou sous le corps 2.In the case of a water-permeable material, a sealed zone may be provided in below the collector duct 3 to prevent drainage water from draining into the ground. This waterproof zone may consist of a sole (not shown) made in an impermeable material incorporated in or under the body 2.

Le conduit collecteur 3 longitudinal est disposé dans la partie inférieure du corps 2 pour pouvoir collecter les eaux de drainage par gravité. Il est rectiligne et sensiblement parallèle à la base 20 dudit corps. Il a une section circulaire mais pourrait avoir une section de forme différente. Il peut, selon les besoins et la nature du matériau constituant ledit corps 2, comporter une enveloppe intérieure étanche (non représentée) rapportée ou intégrée en utilisant un procédé de surmoulage par exemple. Ce conduit collecteur 3 comporte également des extrémités 30 de plus grand diamètre, agencées pour recevoir les moyens de raccordement 6 décrits plus loin.The longitudinal collector duct 3 is arranged in the part lower body 2 to collect drainage water by gravity. It is rectilinear and substantially parallel to the base 20 of said body. It has a circular section but could have a section of different shape. He may, according to the needs and nature of the material constituting said body 2, comprising an inner envelope watertight (not shown) reported or integrated using a method of overmolding for example. This manifold duct 3 also has ends 30 of larger diameter, arranged to receive the connecting means 6 described later.

Les passages de ruissellement 5 sont constitués, dans cet exemple, par des rainures périphériques 50 débouchant dans le conduit collecteur 3 par des canaux transversaux 51 prévus de part et d'autre dudit conduit. Les rainures périphériques 50 sont sensiblement identiques et ont un profil en U, mais pourraient avoir un profil de forme différente, de profondeur plus ou moins grande. Elles sont ménagées dans les parois supérieure 22 et latérales 21 du corps 2. Elles sont rectilignes et disposées à intervalle régulier tout le long du bloc de drainage 1. La section du bloc de drainage 1 illustrée par la figure 3 montre que chaque rainure 50 définit, en partie médiane et à proximité de la paroi supérieure 22, un sommet duquel s'étend de part et d'autre un plan incliné pour faciliter la circulation des eaux de drainage par gravité.The runoff passages 5 are constituted, in this example, by grooves peripherals 50 opening into the collector duct 3 by transverse channels 51 provided on both sides of said duct. The peripheral grooves 50 are substantially identical and have a U-shaped profile, but could have a shape profile different, of greater or lesser depth. They are formed in the walls upper 22 and lateral 21 of the body 2. They are rectilinear and arranged at intervals regular along the drainage block 1. The section of the drainage block 1 shown in FIG. 3 shows that each groove 50 defines, in the middle part and in the vicinity of the upper wall 22, a top of which extends on both sides an inclined plane to facilitate the circulation of drainage water by gravity.

Les canaux transversaux 51 sont orientés sensiblement perpendiculairement au conduit collecteur 3 et disposés de telle manière à déboucher dans ce conduit collecteur 3 tangentiellement à son fond. Ils sont identiques et ont une section circulaire mais pourraient avoir une section de forme différente. Ils peuvent être légèrement inclinés en direction dudit conduit collecteur 3 pour favoriser la circulation des eaux de drainage par gravité. Dans l'exemple représenté, chaque canal transversal 51 est raccordé à trois rainures périphériques 50. La section de chaque canal transversal 51 est supérieure à celle des rainures périphériques 50, de même que la section du conduit collecteur 3 est nettement supérieure à celle des canaux transversaux 51, pour pouvoir répondre au débit des eaux de drainage.The transverse channels 51 are oriented substantially perpendicular to the manifold duct 3 and arranged so as to open into this conduit collector 3 tangentially at its bottom. They are identical and have a section circular but could have a section of different shape. They can be slightly inclined towards said manifold duct 3 to promote circulation drainage water by gravity. In the example shown, each transverse channel 51 is connected to three peripheral grooves 50. The section of each channel transverse 51 is greater than that of peripheral grooves 50, as the section of the collector duct 3 is clearly greater than that of the channels transverse 51, to be able to respond to the flow of drainage water.

Les moyens de raccordement 6 comportent, dans l'exemple illustré par la figure 4, un manchon 60 distinct du corps 2, cylindrique et ayant un diamètre extérieur au plus égal au diamètre intérieur des extrémités 30 du conduit collecteur 3. Ce manchon 60 est destiné à s'emboíter dans les extrémités 30 en regard des conduits collecteurs 3 de deux blocs de drainage 1 consécutifs permettant de les assembler linéairement.The connection means 6 comprise, in the example illustrated by FIG. sleeve 60 distinct from the body 2, cylindrical and having an outside diameter at most equal to the inside diameter of the ends 30 of the collecting duct 3. This sleeve 60 is intended to fit into the ends 30 facing the collector ducts 3 of two consecutive drainage blocks 1 to assemble linearly.

Ces moyens de raccordement 6 comportent également une ouverture latérale 61 prévue dans chaque paroi latérale 21 du corps 2 au même niveau que le conduit collecteur 3, à proximité d'une de ses extrémités et débouchant dans ce conduit. Ces ouvertures latérales sont circulaires mais pourraient avoir une forme différente et présentent un diamètre sensiblement égal à celui des extrémités 30 dudit conduit. Elles sont agencées pour recevoir le manchon 60 permettant d'assembler en angle droit deux blocs de drainage 1 consécutifs, comme représenté à la figure 4. Ces ouvertures latérales 61 sont délimitées par une zone prédécoupée 62 formée dans les parois latérales 21 dudit corps 2. Pour les utiliser, il faut retirer la zone prédécoupée 62 qui forme alors un bouchon servant à obturer l'extrémité 30 du conduit collecteur 3 correspondant.These connection means 6 also include a lateral opening 61 provided in each side wall 21 of the body 2 at the same level as the conduit collector 3, near one of its ends and opening into this conduit. These side openings are circular but could have a different shape and have a diameter substantially equal to that of the ends 30 of said duct. They are arranged to receive the sleeve 60 for assembling at right angles two consecutive drainage blocks 1, as shown in FIG. lateral 61 are delimited by a pre-cut zone 62 formed in the walls 2. To use them, it is necessary to remove the pre-cut zone 62 which then forms a plug for closing the end 30 of the collector duct 3 corresponding.

L'enveloppe extérieure 7 est constituée d'un tissu réalisé dans une matière géotextile, de forme sensiblement rectangulaire, destiné à être enroulé autour du corps 2 et si besoin agrafé sur le corps. Les dimensions longitudinales de ce tissu 7 sont supérieures à celles du bloc de drainage 1 de manière à recouvrir au moins partiellement le bloc de drainage 1 suivant. Ainsi la zone d'assemblage entre deux blocs de drainage 1 consécutifs est également recouverte. Ce tissu 7 permet de retenir les particules de terre, les cailloux et tout autre matériau susceptibles de colmater les passages de ruissellement 5 du bloc de drainage 1 et donc de rendre ce dernier inefficace. Bien entendu d'autres moyens équivalents pourraient également convenir comme par exemple une enveloppe à mailles très fines, collée, surmoulée ou rapportée autour dudit corps 2.The outer casing 7 is made of a fabric made of a geotextile material, of substantially rectangular shape, intended to be wrapped around the body 2 and if need stapled on the body. The longitudinal dimensions of this fabric 7 are greater than those of the drainage block 1 so as to cover at least partially the next drainage block 1. So the assembly area between two 1 consecutive drainage blocks is also covered. This fabric 7 makes it possible to retain particles of earth, pebbles and any other material likely to clog the runoff passages 5 of the drainage block 1 and thus make it ineffective. Of course other equivalent means could also be suitable as for example a very fine mesh envelope, glued, overmoulded or reported around said body 2.

L'utilisation et la mise en oeuvre du bloc de drainage 1 modulaire selon l'invention sont très simples. Les blocs de drainage 1, réalisés par exemple en polystyrène expansé, ont l'avantage d'être peu chers, très légers, faciles à manipuler et à travailler, et de pouvoir se poser par tous les temps même à très basse température. De plus, ils sont non polluants, imputréscibles et ne gardent pas l'humidité.The use and implementation of the modular drainage block 1 according to the invention are very simple. The drainage blocks 1, made for example of polystyrene expanded, have the advantage of being inexpensive, very light, easy to handle and to work, and to be able to land in all weathers even at very low temperatures. In addition, they are non-polluting, imputrccible and do not keep moisture.

La figure 1 permet de comparer très clairement la méthode de drainage traditionnelle, à gauche, à celle effectuée avec le bloc de drainage 1 selon l'invention, à droite. Une tranchée 90 est creusée autour des fondations 9 d'un bâtiment. Dans la méthode traditionnelle, on recouvre la tranchée d'un tissu géotextile, on y dépose le tuyau collecteur perforé, sur lequel on déverse des graviers que l'on recouvre ensuite avec les deux pans de tissu géotextile, puis on remblaie.Figure 1 compares very clearly the traditional drainage method, on the left, to that made with the drainage block 1 according to the invention, on the right. A trench 90 is dug around the foundations 9 of a building. In the method traditional, we cover the trench with a geotextile fabric, we put down the pipe perforated collector, on which gravel is poured and then covered with both sections of geotextile fabric, then fill.

Avec le bloc de drainage 1 de l'invention, on positionne les blocs de drainage 1 directement dans le fond de la tranchée 90 aménagé en légère pente, on les assemble l'un au bout de l'autre par les manchons 60 puis on remblaie. On constate aisément que la réalisation d'un drainage est grandement simplifiée par le fait que le bloc de drainage 1 intègre dans un seul module à la fois le conduit collecteur, les passages de ruissellement et le filtre géotextile.With the drainage block 1 of the invention, the drainage blocks 1 are positioned. directly in the bottom of the trench 90 arranged in a slight slope, they are assembled one at the end of the other by the sleeves 60 and then backfill. It is easy to see that the realization of a drainage is greatly simplified by the fact that the block of drainage 1 integrates into a single module at a time the collector pipe, the passages of runoff and the geotextile filter.

Ce système de drainage, une fois en place, a l'avantage d'assurer un drainage efficace et durable dans le temps, les blocs de drainage 1 étant dimensionnellement très stables, malgré les éventuels glissements de terrain. Les eaux de drainage sont filtrées par l'enveloppe géotextile 7 et sont canalisées par les rainures périphériques 50 dans lesquelles elles s'écoulent par gravité jusqu'aux canaux transversaux 51, qui les centralisent dans le conduit collecteur 3, ce dernier les évacuant dans le réseau d'assainissement.This drainage system, once in place, has the advantage of ensuring effective drainage and durable over time, the drainage blocks 1 being dimensionally very stable, despite possible landslides. The drainage water is filtered by the geotextile envelope 7 and are channeled by the peripheral grooves 50 in which they flow by gravity to the transverse channels 51, which centralize in the collector pipe 3, the latter discharging them into the network sanitation.

Ainsi, les buts de l'invention sont entièrement atteints. Thus, the objects of the invention are fully achieved.

La présente invention n'est toutefois pas limitée à l'exemple de réalisation décrit mais s'étend à toute modification et variante évidentes pour un homme du métier tout en restant dans l'étendue de la protection conférée par les revendications annexées.The present invention is however not limited to the embodiment described but extends to any obvious modification and variation for a person skilled in the art while remaining within the scope of protection conferred by the appended claims.

Notamment et en référence aux figures 5A et 5B, les moyens de raccordement 6 peuvent être constitués d'un manchon 63 formant une seule pièce avec le corps 2, disposé en prolongement d'une des extrémités du conduit collecteur 3 et agencé pour former une partie mâle. L'autre extrémité 64 du conduit collecteur 3 est agencée pour former une partie femelle destinée à recevoir la partie mâle 63 d'un bloc de drainage 1 adjacent. Ce bloc de drainage n'est pas couvert par les revendications parce que les passages de ruissellement 5 sont constitués d'une multitude de canaux transversaux 52, rectilignes et de petite section, s'étendant directement des parois périphériques du corps 2 du bloc de drainage 1 au conduit collecteur 3. Le bloc de drainage permet d'illustrer des moyens de raccordement selon l'invention.In particular, and with reference to FIGS. 5A and 5B, the means of connection 6 may consist of a sleeve 63 forming a single piece with the body 2, arranged in extension of one of the ends of the collector duct 3 and arranged to form a male part. The other end 64 of the collector duct 3 is arranged to form a female portion for receiving the male portion 63 of a drainage block 1 adjacent. This drainage block is not covered by the claims because runoff passages 5 consist of a multitude of transverse channels 52, rectilinear and of small section, extending directly from the peripheral walls of the body 2 of the drainage 1 to the manifold 3. The drainage block is used to illustrate connection means according to the invention.

En référence aux figures 6 et 7, les passages de ruissellement 5 peuvent être également constitués de chicanes périphériques 53 débouchant dans le conduit collecteur 3 par des canaux transversaux 51. Ces chicanes périphériques 53 peuvent être constituées par des formes en relief prévues en périphérie du corps 2, comme par exemple des plots ronds 54 (cf. fig. 6) ou des plots parallélépipédiques 55 (cf. fig. 7) ou encore toute autre forme de géométrie différente.With reference to FIGS. 6 and 7, the runoff passages 5 may be also constituted by peripheral baffles 53 opening into the duct manifold 3 through transverse channels 51. These peripheral baffles 53 can be constituted by relief shapes provided on the periphery of the body 2, as Examples of round studs 54 (see Fig. 6) or parallelepiped studs 55 (see Fig. 7) or any other form of different geometry.

Bien entendu, les formes et les dimensions du bloc de drainage et de ses différents conduits et canaux peuvent différer sans pour cela sortir de la protection définie par les revendications annexées.Of course, the shapes and dimensions of the drainage block and its different channels and channels may differ without departing from the protection defined by the appended claims.
