Description

BOITE DE DRAINAGE POUR APPAREIL DE DISTRIBUTION D'EAU A COLONNE  DRAIN BOX FOR COLUMN WATER DISPENSING APPARATUS
DOMAINE TECHNIQUE TECHNICAL AREA
La présente invention se rapporte au domaine technique général des réseaux de distribution d'eau enterrés et aux boîtes de drainage destinées à équiper et protéger certains appareils montés sur de tels réseaux de distribution, et en particulier les appareils de distribution d'eau du type bouche d'incendie, poteau d'incendie ou borne de puisage. The present invention relates to the general technical field of buried water distribution networks and drainage boxes for equipping and protecting certain devices mounted on such distribution networks, and in particular the mouth-type water dispensing apparatus. fire, fire hydrant or bollard.
La présente invention concerne une boîte de drainage destinée à équiper la partie enterrée d'un appareil de distribution d'eau, du type bouche d'incendie, poteau d'incendie ou borne de puisage par exemple, et à être montée sur la colonne sensiblement verticale de l'appareil et sur la ou les canalisation(s) d'alimentation de ladite colonne, ladite ou lesdites canalisation(s) s'étendant sensiblement orthogonalement à ladite colonne. The present invention relates to a drainage box intended to equip the buried part of a water distribution device, such fire hydrant, fire hydrant or bollard for example, and to be mounted on the column substantially vertical of the apparatus and on the supply pipe (s) of said column, said pipe or conduits (s) extending substantially orthogonally to said column.
TECHNIQUE ANTERIEURE PRIOR ART
Il est déjà connu d'avoir recours à des boîtes de protection et de drainage qui sont destinées à équiper la partie enterrée de pièces faisant partie d'un réseau de distribution d'eau. It is already known to use protection boxes and drainage that are intended to equip the buried part of parts forming part of a water distribution network.
De telles boîtes sont par exemple décrites dans le brevet US-4,905,725 qui divulgue deux pièces en matériau plastique destinées à être assemblées entre elles pour former un coffret destiné à être monté sur et autour d'une vanne de commande d'un réseau d'alimentation d'eau enterré. Le coffret est destiné à être monté à la fois sur la vanne enterrée et sur la canalisation d'alimentation d'eau alimentant la vanne. A cet effet, le coffret comporte deux ouvertures opposées ménagées dans sa partie inférieure pour accommoder le passage de la canalisation d'alimentation et un orifice supérieur, se présentant sous la forme d'un collier cylindrique pour intégrer et protéger la vanne de commande, ledit collier présentant un orifice s'étendant orthogonalement aux ouvertures destinées au passage de la canalisation d'alimentation. Les boîtes sont mises en place sur les canalisations et vannes ou dispositifs équivalents après réalisation d'une fouille laquelle, une fois la mise en place effectuée, est remblayée. Such boxes are for example described in US Pat. No. 4,905,725, which discloses two pieces of plastic material intended to be assembled together to form a box intended to be mounted on and around a control valve of a supply network. of buried water. The cabinet is intended to be mounted on both the buried valve and the water supply pipe supplying the valve. For this purpose, the box comprises two opposite openings formed in its lower part to accommodate the passage of the supply pipe and an upper orifice, in the form of a cylindrical collar to integrate and protect the control valve, said collar having an orifice extending orthogonally to the openings for the passage of the supply line. The boxes are put in place on the pipes and valves or equivalent devices after completion of a search which, once the establishment carried out, is backfilled.
De tels dispositifs doivent ainsi, non seulement assurer une protection directe des pièces formant le réseau de distribution qu'elles entourent contre des agressions diverses et directes, mais encore créer un vide d'air souterrain suffisant pour assurer un drainage de l'eau constant et efficace dans le temps au niveau de la zone protégée par la boîte. Such devices must thus not only provide direct protection of the parts forming the distribution network they surround against various and direct aggression, but also create a sufficient underground air vacuum to ensure a constant drainage of water and effective over time in the area protected by the box.
Or, il s'avère que les boîtes de drainage connues à ce jour ne permettent pas d'assurer un drainage suffisant et souffrent par ailleurs de divers autres inconvénients. However, it turns out that the drainage boxes known to date do not ensure sufficient drainage and also suffer from various other disadvantages.
En particulier, il s'avère que la réalisation d'une boîte de drainage efficace implique de disposer d'une boîte de drainage dont les dimensions sont parfaitement adaptées et ajustées à l'encombrement et aux dimensions de l'élément du réseau de distribution d'eau que l'on veut protéger et pour lequel on veut réaliser un bon drainage périphérique. Un ajustement relatif des dimensions et configurations entre les deux pièces est en effet requis si l'on veut à la fois assurer la création d'un vide d'air et en même temps empêcher la pénétration de la terre et/ou de cailloux ou éléments équivalents lors du remblayage et au cours du temps. In particular, it turns out that the realization of an effective drainage box involves having a drainage box whose dimensions are perfectly adapted and adjusted to the size and dimensions of the element of the distribution network. water that we want to protect and for which we want to achieve a good peripheral drainage. A relative adjustment of the dimensions and configurations between the two parts is indeed required if one wants both to ensure the creation of a vacuum and at the same time prevent the penetration of the earth and / or pebbles or elements equivalent during backfilling and over time.
Pour atteindre un tel objectif, il est alors nécessaire de réaliser des boîtes de drainage spécifiques ayant des dimensions et configurations adaptées et précises pour s'adapter à chacune des pièces du réseau de distribution et d'alimentation d'eau disponibles sur le marché. To achieve such an objective, it is then necessary to achieve specific drainage boxes having dimensions and configurations adapted and accurate to adapt to each of the parts of the distribution network and water supply available on the market.
Ceci implique la fabrication de pièces et de boîtes aux dimensions spécifiques dont le coût est élevé et dont l'usage est strictement réservé au modèle d"appareil de distribution d'eau pour laquelle elle a été conçue. C'est le cas par exemple du coffret décrit dans le brevet US-4,905,725 qui ne peut être monté sur une autre vanne de commande que celle décrite sauf à accepter une diminution de la qualité de protection et/ou une modification in situ du coffret pour un résultat de toute façon non optimal tout en compliquant fortement les opérations de montage. 11 s'avère d'ailleurs en pratique, que lorsque les pièces spécifiques ne sont pas disponibles, des boîtes de drainage aux dimensions non adaptées et de fortune, et donc plus grandes que celles requises et non ajustées, sont mises en place ce qui conduit à un drainage de mauvaise qualité puisque le vide d'air crée est limité voire inexistant à plus ou moins court terme. This involves the manufacture of cost-specific parts and boxes with a high cost, the use of which is strictly limited to the model of the water distribution apparatus for which it was designed. cabinet described in US Pat. No. 4,905,725 which can not be mounted on a control valve other than that described except to accept a reduction in the quality of protection and / or an in situ modification of the cabinet for a non-optimal result anyway by greatly complicating assembly operations. when specific parts are not available, drainage boxes of unsuitable size and makeshift, and therefore larger than those required and unadjusted, are put in place which leads to a poor quality drainage since the vacuum of created air is limited or non-existent in more or less short term.
L'existence d'un drainage défectueux, voire inexistant dans la partie souterraine de l'appareil de distribution d'eau conduit à l'apparition de toute une série de phénomènes particulièrement néfastes tels par exemple et de manière non limitative, des affaissements de terrain localisés dus au gel, des éclatements de conduites dus également au gel par absence ou difficulté de vidange de conduite, des blocages de pièces de commande dus à la corrosion générée par la stagnation d'eau ou au passages de racines par défaut de protection .... The existence of a defective or non-existent drainage in the underground part of the water distribution apparatus leads to the appearance of a whole series of particularly harmful phenomena such as, for example and without limitation, subsidence of ground localized due to freezing, burst pipes also due to frost due to lack or difficulty of pipe emptying, blockages of control parts due to corrosion caused by water stagnation or root passages due to lack of protection. ..
Il convient par conséquent d'éviter l'apparition de ces phénomènes et de pouvoir disposer de boîtes de drainage facilement adaptables à un grand nombre de situations dimensionnelles et de configurations tout en étant capables de réaliser un drainage efficace et tout en étant d'une mise en place facile. It is therefore necessary to avoid the occurrence of these phenomena and to have drainage boxes easily adaptable to a large number of dimensional situations and configurations while being able to achieve effective drainage and while being a in easy place.

MEILLEURE MANIERE DE REALISER L'INVENTION BEST MODE OF REALIZING THE INVENTION
Tel qu'illustré, en particulier aux figures 6 et 8, la boîte de drainage 1 conforme à l'invention est destinée à être implantée sous le niveau du sol 2 pour équiper ainsi tout ou partie de la partie ou section enterrée 3 d'un appareil de distribution d'eau 4 du type poteau d'incendie (figures 7 et 8) ou de distribution d'eau ou bouche d'incendie (figure 6) par exemple. As illustrated, in particular in FIGS. 6 and 8, the drainage box 1 according to the invention is intended to be implanted under the level of the ground 2 so as to equip all or part of the buried part or section 3 of a water distribution apparatus 4 of the fire hydrant type (FIGS. 7 and 8) or water distribution or fire hydrant (FIG. 6), for example.
En règle générale, les appareils de distribution d'eau 4 comprennent une colonne d'alimentation 5 qui est enterrée et de dimensions intérieure et extérieure variables selon le modèle, la marque et l'utilisation envisagée. In general, the water dispensing apparatus 4 comprises a feed column 5 which is buried and of variable internal and external dimensions depending on the model, the mark and the intended use.
En régie générale, les colonnes d'alimentation 5 présentent une section sensiblement cylindrique comprise entre 160 et180 mm, et en générai de l'ordre de 170 mm+/- 10 mm. Tel qu'illustré aux figures 6 à 8, la colonne 5 est disposée de manière sensiblement verticale dans le sol et se prolonge au-delà de la partie enterrée 3 et au-dessus du niveau du sol 2, dans le cas d'un poteau d'incendie (figures 7 et 8), par une partie aérienne pourvue d'une ou plusieurs prises d'eau 7. In general, the feed columns 5 have a substantially cylindrical section of between 160 and 180 mm, and generally of the order of 170 mm +/- 10 mm. As illustrated in FIGS. 6 to 8, the column 5 is disposed substantially vertically in the ground and extends beyond the buried portion 3 and above the ground level 2, in the case of a pole fire (Figures 7 and 8), by an aerial part provided with one or more water intakes 7.
Dans le cas de la bouche d'incendie illustrée à la figure 6, la colonne 5 est surmontée, dans sa partie enterrée 3, par un coffre 8, contenant les prises d'eau, ledit coffre 8 étant lui-même surmonté par un couvercle 9 s'étendant sensiblement au niveau du sol 2. In the case of the fire hydrant illustrated in FIG. 6, the column 5 is surmounted, in its buried part 3, by a box 8, containing the intakes, said box 8 being itself surmounted by a cover 9 extending substantially at ground level 2.
Au sens de l'invention, il doit être entendu que les appareils de distribution d'eau 4 sur lesquels la boîte de drainage 1 conforme à l'invention est destinée à être montée, ne sont nullement limités aux deux exemples de réalisation illustrés aux figures 6 à 8, mais comprennent au contraire tous les appareils de distribution d'eau équivalents tels les appareils de distribution d'eau à colonne et équipé d'un système de vidange/purge, tels par exemple, bouche d'incendie, poteau d'incendie ou borne de puisage dès lors qu'ils comprennent une colonne verticale d'alimentation 5. La colonne d'alimentation 5 se termine vers sa partie inférieure 11 par un méplat de fixation 12 destiné à coopérer avec le méplat d'une première bride de fixation 14A d'un coude de liaison 13, de préférence à 90 ° assurant par l'intermédiaire d'une seconde bride de fixation 14 A1 la liaison étanche avec une canalisation d'alimentation 15 elle-même pourvue d'un bride de fixation 14B. La fixation entre les pièces s'effectue par tous moyens appropriés, et par exemple par vissage. Within the meaning of the invention, it should be understood that the water distribution devices 4 on which the drainage box 1 according to the invention is intended to be mounted, are not limited to the two embodiments illustrated in the figures 6 to 8, but on the contrary include all equivalent water dispensing devices such as column water dispensers and equipped with a drain / purge system, such as, for example, fire hydrant, pole of water fire or draw-off point as long as they comprise a vertical supply column 5. The supply column 5 terminates towards its lower part 11 by a fastening surface 12 intended to cooperate with the flat part of a first flange of 14A attachment of a connecting bend 13, preferably 90 ° ensuring through a second fastening flange 14 A 1 the sealed connection with a supply pipe 15 itself provided with a fastening flange 14B. Fixing between the parts is carried out by any appropriate means, for example by screwing.
Tel qu'illustré aux figures 6 à 8, la canalisation 15, par exemple de section cylindrique, s'étend sensiblement orthogonalement à la colonne 5 en formant, par l'intermédiaire du coude 13, un angle de l'ordre de 90°. As illustrated in FIGS. 6 to 8, the pipe 15, for example of cylindrical section, extends substantially orthogonally to the column 5 forming, via the bend 13, an angle of the order of 90 °.
La boîte de drainage selon l'invention est donc destinée à assurer le drainage d'un appareil de distribution d'eau qui non seulement comprend une colonne d'alimentation 5 sensiblement verticale, mais encore, et à un niveau inférieur au moins une canalisation d'alimentation 15 s'étendant orthogonalement à ladite colonne d'alimentation 5. Tel qu'illustré aux figures 7 et 8, certaines installations nécessitent un calage, en particulier du coude 13par l'intermédiaire de moyens de calage, tels une butée 17, disposée dans l'alignement de la canalisation 15 lorsque cette dernière ne se prolonge pas au-delà de l'aplomb de la colonne 5, comme c'est le cas en revanche à la figure 6. The drainage box according to the invention is thus intended to ensure the drainage of a water dispensing apparatus which not only comprises a substantially vertical feed column, but also, and at a lower level at least one water pipe. supply 15 extending orthogonally to said supply column 5. As illustrated in FIGS. 7 and 8, some installations require wedging, in particular of the elbow 13 by means of wedging means, such as an abutment 17, arranged in alignment with the pipe 15 when the latter is not prolonged. beyond the column 5, as is the case in Figure 6.
Tel qu'illustré en particulier à la figure 1 , la boîte de drainage 1 conforme à l'invention se présente sous la forme générale d'un coffret 20 délimité extérieurement par des parois 21 et comportant un corps central 22 sensiblement cylindrique, le corps central 22 comportant deux excroissances latérales 25 diamétralement opposées en considération de l'axe de symétrie X-X' du corps central 22 et s'étendant à partir de la base 26 du corps central sensiblement jusqu'à mi-hauteur dudit corps central 22 tout en s'étendant vers l'extérieur de ce dernier. Les deux excroissances latérales 25 forment de préférence un porche avec un toit 43 pourvu d'un apex central 44 et deux joues latérales 45, le porche étant fermé par une cloison 41. La partie supérieure de la boîte de drainage 1 comporte une ouverture 27, par exemple circulaire, s'étendant au niveau du corps centra] 22 et destinée à venir enserrer la périphérie de la colonne 5 lorsque la boîte de drainage 1 est montée sur cette dernière. La partie inférieure de la boîte de drainage 1 est ouverte. As illustrated in particular in Figure 1, the drainage box 1 according to the invention is in the general form of a box 20 delimited externally by walls 21 and having a substantially cylindrical central body 22, the central body 22 having two diametrically opposite lateral protuberances 25 in consideration of the axis of symmetry XX 'of the central body 22 and extending from the base 26 of the central body substantially to half the height of said central body 22 while s' extending outward of the latter. The two lateral protuberances 25 preferably form a porch with a roof 43 provided with a central apex 44 and two lateral cheeks 45, the porch being closed by a partition 41. The upper part of the drainage box 1 comprises an opening 27, for example circular, extending at the central body 22] and intended to grip the periphery of the column 5 when the drainage box 1 is mounted on the latter. The lower part of the drainage box 1 is open.
Selon une caractéristique importante de l'invention, la boîte de drainage comporte un système d'adaptation aux dimensions et encombrements d'une part de la colonne 5 et d'autre part au moins de la ou des canalisation(s) d'alimentation 15 pour former un système d'adaptation multi-étagé, de préférence bi-étagé, et universel permettant un montage ajusté ou sensiblement ajusté sur ou contre la colonne 5 et autour de la ou des canalisations(s) d'alimentation 15. According to an important characteristic of the invention, the drainage box comprises a system for adapting to dimensions and dimensions on the one hand of the column 5 and on the other hand at least of the supply line (s) 15 to form a multi-stage, preferably two-stage, universal adaptation system enabling an adjusted or substantially fitted fitting on or against the column 5 and around the supply pipe (s) 15.
La boîte de drainage 1 selon l'invention est ainsi pourvue d'un système permettant de s'adapter de manière continue et au plus près aux dimensions, et en particulier au diamètre des différents types de colonne 5 que l'on peut rencontrer sur le marché tout en permettant d'assurer un bon drainage. Le système d'adaptation permet également de s'adapter facilement aux dimensions et en particulier à la variabilité des conformations que l'on trouve dans les équipements présents dans les zones de raccordement entre les canalisations 15 et la colonne 5 et ce à plusieurs niveaux de profondeur. Il s'adapte à la différence de configuration des conduits qui s'étendent dans des directions différentes tout en tenant également compte de leur niveau d'enfouissement dans le sol, profondeur et de leur encombrement qui sont également différents. The drainage box 1 according to the invention is thus provided with a system making it possible to adapt continuously and as closely as possible to the dimensions, and in particular to the diameter of the different types of column 5 that can be encountered on the market while ensuring good drainage. The adaptation system also makes it easy to adapt to the dimensions and in particular to the variability of the conformations found in the equipment present in the connection zones between the pipes 15 and the column 5 and this at several levels of depth. It adapts to the configuration difference of the ducts that extend into different directions while also taking into account their level of burial in the soil, depth and their footprint that are also different.
Selon une version préférentielle de l'invention, le système d'adaptation comprend des premiers moyens d'adaptation 30 disposés à la partie supérieure de la boîte 1 pour s'accommoder de manière continue au diamètre de la colonne 5 tout en permettant le drainage, et des seconds moyens d'adaptation 40 situés à la partie inférieure de la boîte 1 pour s'accommoder, avantageusement de manière discontinue, aux dimensions et encombrements de la ou des canalisation(s) d'alimentation 15 ainsi, optionnellement, qu'aux dispositifs ou moyens de calage prévus pour réaliser la butée de l'appareil, ces moyens étant mis en place côté opposé à la jonction entre la canalisation 15 et le coude 13. Dans sa version la plus simple, les seconds moyens d'adaptation 40 peuvent ainsi n'être prévus que pour s'accommoder aux dimensions et encombrements d'une canalisation d'alimentation 15. Selon une version particulièrement avantageuse et préférentielle de l'invention, les premiers moyens d'adaptation 30 sont formés par une pluralité de lamelles 31 formant une collerette 32 circulaire délimitant l'ouverture 27 de dimension prédéterminée dans la partie supérieure de la boîte de drainage 1 , ladite ouverture 27 étant destinée au passage de la colonne 5 et lesdites lamelles 31 présentant une certaine souplesse pour s'adapter par déformation aux dimensions de la colonne 5. A titre d'exemple, le diamètre prédéterminé au repos de l'ouverture 27 est de l'ordre de 165 mm et peut être compris entre 160 et 180 mm. Les premiers moyens d'adaptation 30 peuvent d'ailleurs former une invention indépendante lorsqu'ils sont constitués de lamelles 31. According to a preferred version of the invention, the adaptation system comprises first adaptation means 30 arranged at the upper part of the box 1 to accommodate continuously the diameter of the column 5 while allowing drainage, and second matching means 40 located at the lower part of the box 1 to accommodate, advantageously discontinuously, the dimensions and dimensions of the pipe (s) supply and 15, optionally, as devices or means of wedging provided to achieve the stop of the apparatus, these means being placed opposite side to the junction between the pipe 15 and the bend 13. In its simplest version, the second adaptation means 40 can thus be provided only to accommodate the dimensions and dimensions of a supply line 15. According to a particularly advantageous and preferred version of the invention, the first means s of adaptation 30 are formed by a plurality of lamellae 31 forming a circular flange 32 delimiting the opening 27 of predetermined size in the upper part of the drainage box 1, said opening 27 being intended for the passage of the column 5 and said lamella 31 having a certain flexibility to adapt by deformation to the dimensions of the column 5. For example, the predetermined diameter at rest of the opening 27 is of the order of 165 mm and can be between 160 and 180 mm. The first adaptation means 30 may also form an independent invention when they consist of lamellae 31.
Ainsi, et tel qu'illustré, la partie supérieure du corps central 22 se prolonge par une bordure périphérique 35 repliée vers l'intérieur dudit corps central, ladite bordure se prolongeant par la collerette 32 constituée par les lamelles 31. Thus, and as illustrated, the upper part of the central body 22 is extended by a peripheral edge 35 folded towards the inside of said central body, said border extending by the flange 32 constituted by the lamellae 31.
La boîte de drainage 1 sera avantageusement réalisée en matériau composite de manière à lui conférer un poids faible tout en assurant une bonne résistance mécanique de l'ensemble ainsi qu'une souplesse suffisante aux lamelles 31 pour leur permettre de fléchir, sans risque de rupture, et s'adapter précisément au diamètre de la colonne 5 supérieur à celui de l'ouverture 27. Grâce à ce système d'adaptation, il est ainsi possible de réaliser une boîte de drainage 1 dont ie diamètre moyen de l'ouverture 27, par exemple de l'ordre de 165et compris entre 160 et 180 mm, est capable de s'adapter à une large gamme de dimensions de colonnes 5. The drainage box 1 will advantageously be made of composite material so as to give it a low weight while ensuring good mechanical strength of the assembly and sufficient flexibility to the slats 31 to allow them to flex without risk of rupture, and adapt precisely to the diameter of the column 5 greater than that of the opening 27. With this adaptation system, it is thus possible to produce a drainage box 1 whose average diameter of the opening 27, for example of the order of 165and between 160 and 180 mm, is able to adapt to a wide range of column sizes 5.
Les lamelles 31 sont avantageusement non jointives et elles laissent par exemple entre elles un espace de l'ordre de 1 mm afin de s'adapter à différents diamètres de colonne et d'améliorer le drainage de l'eau sans pour autant permettre le passage de la terre de remblayage. A titre de variante, les lamelles 31 peuvent néanmoins être jointives. The lamellae 31 are advantageously non-contiguous and leave, for example, between them a space of the order of 1 mm in order to adapt to different column diameters and to improve drainage of the water without allowing the passage of water. the land of backfilling. Alternatively, the slats 31 may nevertheless be contiguous.
Tel qu'illustré aux figures, la pluralité de lamelles 31 forme un tronc de cône de révolution, par exemple avec un angle au centre a (figure 5) compris entre 60 et150°, et de préférence de l'ordre de 100°. As illustrated in the figures, the plurality of lamellae 31 form a truncated cone of revolution, for example with a central angle a (FIG. 5) between 60 and 150 °, and preferably of the order of 100 °.
Avantageusement, le tronc de cône de révolution est orienté avec sa petite base (formant l'ouverture 27) disposée en dehors de l'enveloppe de la boîte de drainage 1 pour former ainsi un tronc de cône sortant. Advantageously, the truncated cone of revolution is oriented with its small base (forming the opening 27) disposed outside the casing of the drainage box 1 to thereby form an outgoing truncated cone.
Cette disposition assure une meilleure résistance mécanique aux contraintes subies par la boîte de drainage, notamment lors du remblaiement ou lorsque le sol avoisinant est soumis à de fortes contraintes de poids localisées. This arrangement provides better mechanical strength to the stresses experienced by the drainage box, especially during backfilling or when the surrounding soil is subjected to high localized weight constraints.
A titre de variante, le tronc de cône pourrait néanmoins être orienté différemment, et former par exemple un tronc de cône rentrant (non illustré aux figures) à l'intérieur de l'enveloppe de la boîte de drainage 1. Alternatively, the truncated cone could nevertheless be oriented differently, and form for example a retreating cone frustum (not shown in the figures) inside the casing of the drainage box 1.
Tel qu'illustré, les seconds moyens d'adaptation sont formés par une pluralité de zones cassables 41 A, 41 B ménagées dans les cloisons 41 de la boîte de drainage 1 , lesdites zones cassables étant de surfaces prédéterminées de manière à former ou dégager au moins un orifice de sortie 42 adapté à la dimension et à l'encombrement au moins de la ou des canalisation(s) 15. As illustrated, the second adaptation means are formed by a plurality of breakable zones 41 A, 41 B formed in the partitions 41 of the drainage box 1, said breakable zones being of predetermined surfaces so as to form or disengage at at least one outlet orifice 42 adapted to the size and the bulk of at least one of the pipe (s) 15.
Selon une variante préférentielle de l'invention, les seconds moyens d'adaptation 40 peuvent également s'accommoder aux dimensions et encombrement des éventuels moyens de calage (17) mis éventuellement en place pour réaliser le calage de l'appareil (parpaing ou butée 17) côté opposé à la canalisation d'alimentation 15 et au- delà du coude de liaison 13. According to a preferred variant of the invention, the second adaptation means 40 can also accommodate the dimensions and size of the possible setting means (17) possibly put in place to effect the setting of the device (block or abutment 17) opposite to the supply pipe 15 and beyond the connecting bend 13.
Selon une version préférentielle de l'invention illustrée aux figures, notamment aux figures 1 et 7, les zones cassables 41 A, 41 B constituent la totalité de la surface de la cloison 41 d'au moins une excroissance 25. De préférence également, la totalité de la surface de la paroi 41 d'au moins une excroissance latérale 25 est constituée de deux zones cassabies(41A, 41 B superposées. According to a preferred version of the invention illustrated in the figures, in particular in FIGS. 1 and 7, the breakable zones 41A, 41B constitute the entire surface of the partition 41 of at least one protrusion 25. Also preferably, the the entire surface of the wall 41 of at least one lateral protrusion 25 consists of two breakable zones (41A, 41B superimposed.
Selon la version préférentielle illustrée, la totalité de la cloison 41 de chaque excroissance 25 forme une zone cassable, laquelle est avantageusement constituée de deux zones cassables 41 A, 41 B superposées, respectivement inférieure et supérieure, délimitées par des lignes de fragilisation 46 du matériau de manière à réaliser des zones cassables auto-sécables. Lors de la mise en place de la boîte de drainage 1 , il est ainsi possible de s'adapter in situ à l'encombrement de la canalisation 15 et de sa connexion avec l'embout 13 ainsi qu'aux moyens mis éventuellement en place pour assurer le calage de l'appareil, soit en sectionnant l'un des deux volets 41 A, 41 B, inférieur ou supérieur, soit les deux volets 41 A, 41 B tel qu'illustré à la figure 7 par exemple. According to the illustrated preferential version, the whole of the partition 41 of each protrusion 25 forms a breakable zone, which advantageously consists of two breakable zones 41 A, 41 B superimposed, respectively lower and upper, delimited by weakening lines 46 of the material in order to produce self-breaking breakable areas. During the installation of the drainage box 1, it is thus possible to adapt in situ to the size of the pipe 15 and its connection with the tip 13 and the means possibly put in place for ensure the rigging of the device, either by cutting one of the two flaps 41A, 41B, lower or upper or the two flaps 41A, 41B as shown in Figure 7 for example.
Bien évidemment, à titre de variante, les cloisons 41 de chaque excroissance 25 peuvent ne pas être réalisées sous la forme de zones auto-sécables sans pour autant sortir du cadre de l'invention, dès l'instant où la paroi 41 peut être découpée par tout moyen conventionnel bien connu de l'homme du métier, et par exemple par sciage ou tout simplement en les brisant. Of course, as an alternative, the partitions 41 of each protrusion 25 may not be made in the form of self-breakable zones without departing from the scope of the invention, as soon as the wall 41 can be cut by any conventional means well known to those skilled in the art, and for example by sawing or simply by breaking them.
A titre de variante, ii est bien évidemment également envisageable de réaliser les cloisons 41 sous la forme de zones auto-sécables de forme et de nombre quelconque en faisant varier la disposition des lignes de fragilisation 46. Ainsi, à la place de deux zones auto-sécables superposées à partir de la base 26, il est possible de réaliser trois voire quatre zones sécables en forme de quadrilatère ou de forme circulaire notamment. L'une des cloisons 41 (Fig.7) peut également n'être constituée que d'une seule zone auto-sécable pour accommoder les moyens de calage 7. Selon une variante préférentielle de l'invention, la boîte de drainage 1 est formée par au moins deux demi-coques 1A, 1 B, de préférence symétriques et assemblables entre elles, par exemple par clipsage, pour former le coffret 20. Tel qu'illustré, chaque demi- coque 1A, 1 B est pourvue d'une excroissance 25 et de deux demi-collerettes 32 identiques et d'une série d'éléments de clipsage 50, par exemple mâles et femelles, répartis sur chacune des demi-coques 1A, 1 B le long de leurs faces d'assemblage pour assurer leur assemblage. As a variant, it is of course also conceivable to make the partitions 41 in the form of self-breakable zones of any shape and number by varying the arrangement of the embrittlement lines 46. Thus, in place of two auto zones. -sécables superimposed from the base 26, it is possible to achieve three or four breakable areas in the form of quadrilateral or circular in particular. One of the partitions 41 (FIG. 7) may also consist of only one self-breakable zone to accommodate the wedging means 7. According to a preferred variant of the invention, the drainage box 1 is formed by at least two half-shells 1A, 1B, preferably symmetrical and assembled together, for example by clipping, to form the box 20. As illustrated, each half-shell 1A, 1B is provided with an outgrowth 25 and two half-collars 32 identical and a series of clipping elements 50, for example male and female, distributed on each of the half-shells 1A, 1B along their assembly faces to ensure their assembly.
Tel qu'illustré par exemple aux figures 7 et 8, la méthode conduisant à la mise en place de la boîte de drainage 1 conforme à l'invention est la suivante. As illustrated for example in Figures 7 and 8, the method leading to the establishment of the drainage box 1 according to the invention is as follows.
On s'assure tout d'abord de la stabilité de l'appareil de distribution d'eau 4, et en particulier de la colonne 5 et de la canalisation d'alimentation 15. Au besoin, une ou plusieurs butée(s) 17 est (sont) mise en place au fond du remblai. Les dimensions de la canalisation 15 et de l'encombrement de la zone de liaison entre la colonne 5 et la canalisation 15 au niveau du coude 13 sont ensuite estimées ou mesurées de telle sorte que l'on peut préparer la ou les demi-coques 1A, 1 B en découvrant un orifice de sortie 42 adapté au passage de la canalisation 15 et au plus près pas excès. On assure ensuite le sectionnement d'une ou plusieurs zone(s) cassables 41 , 41 A, 41 B en fonction de la dimension et de l'encombrement de la canalisation 15 et/ou de la présence d'une butée 17, puis on assure la mise en place de chacune des deux demi- coques 1A, 1 B qui sont ensuite assemblées entre elles sur place en faisant coopérer entre eux les éléments de clipsage 50 pour assurer leur verrouillage. First of all, the stability of the water distribution apparatus 4, and in particular of the column 5 and the supply line 15, is ensured. If necessary, one or more stop (s) 17 is (are) set up at the bottom of the embankment. The dimensions of the pipe 15 and the bulk of the connection zone between the column 5 and the pipe 15 at the elbow 13 are then estimated or measured so that one or more half-shells 1A can be prepared. , 1 B by discovering an outlet orifice 42 adapted to the passage of the pipe 15 and closer to not excess. One or more breakable zones 41, 41 A, 41 B are then cut off as a function of the size and bulk of the pipe 15 and / or the presence of a stop 17, and then ensures the establishment of each of the two half-shells 1A, 1B which are then assembled together on site by cooperating with each other the clipping elements 50 to ensure their locking.
Au cours de cette opération de rapprochement du verrouillage des deux demi- coques A, 1 B, les lamelles 31 viennent progressivement en contact avec la périphérie externe de la colonne 5 et se déforment pour s'adapter précisément et parfaitement au profil, plus ou moins régulier, de la zone de contact avec la colonne 5. Grâce à l'invention on obtient ainsi un excellent contact entre les lamelles 31 et la colonne 5, ce qui évite l'entrée et le passage de terre lors de l'opération de remblayage et assure la création d'un vide d'air, gage de bon drainage. Les caractéristiques de l'invention permettent ainsi la création d'un véritable vide d'air souterrain au pied des appareils de distribution d'eau permettant un excellent drainage, tout en assurant une bonne protection au pied de l'appareil, notamment contre le passage des racines en réduisant au minimum les zones de pénétration potentielles des racines, la boîte de drainage 1 conforme à l'invention épousant au mieux les formes et le contour des éléments constituant le pied de l'appareil de distribution d'eau 4. During this operation of bringing the locking of the two half-shells A, 1 B closer together, the slats 31 gradually come into contact with the outer periphery of the column 5 and deform to fit precisely and perfectly to the profile, more or less of the contact zone with the column 5. Thanks to the invention, an excellent contact is obtained between the lamellae 31 and the column 5, which avoids the entry and the passage of earth during the backfilling operation. and ensures the creation of an air vacuum, a guarantee of good drainage. The features of the invention thus allow the creation of a real vacuum underground air at the foot of the water dispensing devices for excellent drainage, while providing good protection at the foot of the device, especially against the passage roots by reducing at least the potential zones of penetration of the roots, the drainage box 1 according to the invention best matching the shapes and the outline of the elements constituting the foot of the water dispensing apparatus 4.
L'invention concerne donc également une méthode de mise en place d'une boîte de drainage selon l'invention dans laquelle : The invention therefore also relates to a method of setting up a drainage box according to the invention in which:
- on estime ou on mesure les dimensions de la canalisation 15 et de l'encombrement de la zone de liaison entre la colonne 5 et la canalisation d'alimentation 15,  the dimensions of the pipe 15 and the bulk of the connection zone between the column 5 and the supply pipe 15 are estimated or measured,
