Description

La présente invention concerne un regard pour installations de transport de fluide, par exemple une installation de drainage ou d'égout, du type comprenant un fond de regard en matière plastique à double paroi avec des ouvertures latérales pour y raccorder des entrées et/ou des sorties de fluide, et une ou plusieurs rehausses venant s'adapter sur le fond de regard.The present invention relates to a manhole for fluid transport installations, for example a drainage or sewer installation, of the type comprising a double-walled plastic manhole bottom with lateral openings for connecting inlets and / or fluid outlets, and one or more extensions coming to adapt to the manhole.

On connaît un fond de regard en matière plastique à double paroi, dans lequel l'espace entre les deux parois est destiné à recevoir du béton ou un produit analogue lors de sa pose sur le site, en vue d'augmenter son poids et sa résistance mécanique. Toutefois, on a pu constater qu'un tel fond de regard ne présentait pas une rigidité suffisante à sa partie inférieure, ce qui pouvait poser des problèmes, notamment lors de la mise en place du béton.A double-walled plastic manhole cover is known, in which the space between the two walls is intended to receive concrete or the like during its installation on the site, in order to increase its weight and its resistance. mechanical. However, it has been observed that such a manhole does not have sufficient rigidity at its lower part, which could cause problems, especially during the placing of the concrete.

La présente invention a donc pour but principal de remédier à cet inconvénient et, pour ce faire, elle a pour objet un regard du type susmentionné qui se caractérise essentiellement en ce que la paroi inférieure extérieure du fond de regard est munie de creux servant de nervures de renforcement.The main object of the present invention is therefore to remedy this drawback and, to do this, it relates to a manhole of the aforementioned type which is essentially characterized in that the lower external wall of the manhole is provided with recesses serving as ribs reinforcement.

De préférence, ces creux sont de forme tronconique et le sommet des creux fait partie intégrante de la paroi inférieure intérieure du fond de regard.Preferably, these recesses are of frustoconical shape and the top of the recesses is an integral part of the inner bottom wall of the manhole.

Ainsi, les deux parois inférieures du fond restent parfaitement écartées l'une de l'autre en ménageant un espace dans lequel on peut introduire le béton sans aucune difficulté.Thus, the two bottom bottom walls remain perfectly spaced from each other, providing a space in which the concrete can be introduced without any difficulty.

Dans une forme de réalisation particulière de l'invention, le fond de regard a une section circulaire.In a particular embodiment of the invention, the manhole bottom has a circular section.

Quant aux rehausses, elles sont réalisées en matière plastique avec une double paroi circulaire correspondant à la double paroi du fond et une lèvre inférieure destinée à venir s'emboîter à l'intérieur de la paroi latérale intérieure de l'élément situé immédiatement en dessous.As for the extensions, they are made of plastic with a double circular wall corresponding to the double wall of the bottom and a lower lip intended to come to fit inside the inner side wall of the element located immediately below.

De préférence, un joint plat, rond ou ovale en élastomère est inséré dans le plan de joint entre la rehausse et l'élément situé immédiatement en dessous.Preferably, a flat, round or oval elastomer gasket is inserted in the plane of the joint between the riser and the element located immediately below.

Le cas échéant, les rehausses comportent des ouvertures latérales pour y raccorder des entrées de fluide supplémentaires.If necessary, the extensions have lateral openings for connecting additional fluid inlets.

Une forme d'exécution de l'invention est décrite ci-après à titre d'exemple, en référence aux dessins annexés dans lesquels :

  • - la figure 1 est une vue en perspective d'un fond de regard conforme à l'invention ;
  • - la figure 2 est une vue de dessus de ce fond de regard ;
  • - la figure 3 est une vue en coupe suivant la ligne III-III de la figure 2 ;
  • - la figure 4 est une vue en coupe suivant la ligne IV-IV de la figure 2;
  • - la figure 5 est une vue de dessus d'une rehausse conforme à l'invention ; et,
  • - la figure 6 est une vue en coupe suivant la ligne VI-VI de la figure 5;
An embodiment of the invention is described below by way of example, with reference to the accompanying drawings in which:
  • - Figure 1 is a perspective view of a manhole background according to the invention;
  • - Figure 2 is a top view of this manhole;
  • - Figure 3 is a sectional view along line III-III of Figure 2;
  • - Figure 4 is a sectional view along line IV-IV of Figure 2;
  • - Figure 5 is a top view of an extension according to the invention; and,
  • - Figure 6 is a sectional view along line VI-VI of Figure 5;

Le fond de regard représenté sur les figures 1 à 4 est réalisé d'une seule pièce en matière plastique, par exemple du polyéthylène, par rotomoulage on autre. Il est constitué d'un corps 1 de section cylindrique à double paroi, ouvert à sa partie supérieure, et comporte ainsi une double paroi latérale 2-3 et une double paroi inférieure 4-5.The manhole shown in Figures 1 to 4 is made in one piece of plastic, for example polyethylene, by rotational molding or other. It consists of a body 1 of cylindrical double-walled section, open at its upper part, and thus comprises a double side wall 2-3 and a double lower wall 4-5.

Dans la double paroi latérale 2-3 sont ménagées des ouvertures circulaires 6 en forme de manchons pour y raccorder des tuyaux d'entrée ou de sortie de fluide, l'étanchéité étant assurée par un joint annulaire venant se loger dans une gorge 7 prévue à cet effet dans le manchon. Dans l'exemple de réalisation particulier décrit ici, on a prévu quatre ouvertures de grand diamètre et deux plus petites qui sont situées à un niveau supérieur, comme illustré sur la figure 3. De façon connue en soi, toutes ces ouvertures 6 sont normalement obturées du côté intérieur par un voile de matière 8 qu'il sera facile de découper sur le chantier en fonction des embranchements à réaliser.In the double side wall 2-3, circular openings 6 are provided in the form of sleeves for connecting fluid inlet or outlet pipes, the sealing being ensured by an annular seal which is received in a groove 7 provided at this effect in the sleeve. In the particular embodiment described here, four large diameter and two smaller openings are provided which are located at a higher level, as illustrated in FIG. 3. In a manner known per se, all these openings 6 are normally closed. on the inside by a veil of material 8 which will be easy to cut on the site depending on the branch lines to be made.

Par ailleurs, la double paroi latérale 2-3 est munie dans sa partie supérieure d'un certain nombre de nervures 9 formant entretoises et qui assurent ainsi la rigidité de cette paroi sans l'obturer complètement.Furthermore, the double side wall 2-3 is provided in its upper part with a number of ribs 9 forming spacers and which thus ensure the rigidity of this wall without completely sealing it.

Conformément à la présente invention, la rigidité de la double paroi inférieure 4-5 est assurée par des creux 10 ménagés dans la paroi extérieure 4 et qui servent de nervures de renforcement. Dans l'exemple particulier décrit ici, ces creux sont de forme tronconique et ils sont situés au niveau des passages de fluide, c'est-à-dire dans les parties les plus basses. De plus, le sommet desdits creux tronconiques fait ici partie intégrante de la paroi intérieure 5. Toutefois, lesdits sommets pourraient également prendre simplement appui contre la paroi intérieure sous l'influence de la pression de la terre environnante.According to the present invention, the rigidity of the lower double wall 4-5 is ensured by recesses 10 formed in the outer wall 4 and which serve as reinforcing ribs. In the particular example described here, these recesses are of frustoconical shape and they are located at the level of the fluid passages, that is to say in the lowest parts. In addition, the top of said frustoconical recesses is here an integral part of the inner wall 5. However, said peaks could also simply bear against the inner wall under the influence of the pressure of the surrounding earth.

Le fond de regard qui vient d'être décrit est associé à une ou plusieurs rehausses telles que celle représentée en 11 sur les figures 5 et 6, afin de former un regard complet. Cette rehausse est essentiellement constituée d'un corps cylindrique en matière plastique ouvert aux deux extrémités et comporte également une double paroi latérale 12-13 correspondant à la double paroi latérale 2-3 du fond de regard 1. Elle est munie en partie basse d'une lèvre intérieure 14 destinée à venir s'emboîter dans la paroi latérale intérieure de l'élément inférieur constitué, soit par le fond de regard, soit par une autre rehausse.The manhole cover which has just been described is associated with one or more extensions such as that shown at 11 in FIGS. 5 and 6, in order to form a complete manhole. This extension essentially consists of a cylindrical plastic body open at both ends and has also a double side wall 12-13 corresponding to the double side wall 2-3 of the manhole bottom 1. It is provided in the lower part with an inner lip 14 intended to be fitted into the inner side wall of the element lower formed, either by the back cover, or by another enhancement.

Dans l'exemple de réalisation particulier décrit ici, la rehausse est également pourvue de trois ouvertures 16, analogues aux ouvertures 6 du fond de regard 1, avec une gorge 17 pour le joint d'étanchéité et un voile de matière 18 obturant normalement l'ouverture du côté intérieur. Par ailleurs, cette rehausse est également munie, à la fois en partie haute et en partie basse, de nervures 19 formant entretoises, qui assurent la rigidité de la double paroi latérale 12-­13.In the particular embodiment described here, the extension is also provided with three openings 16, similar to the openings 6 in the manhole cover 1, with a groove 17 for the seal and a web of material 18 normally closing off the opening from the inside. Furthermore, this extension is also provided, both at the top and at the bottom, with ribs 19 forming spacers, which ensure the rigidity of the double side wall 12-13.

La mise en place du regard conforme à l'invention s'éffectue de la manière suivante :The installation of the manhole in accordance with the invention is carried out as follows:

On pose d'abord le fond 1 et on remplit l'espace libre entre les parois latérales 2-3 les parois inférieures 4-5 avec un produit du genre béton afin de le lester et d'augmenter sa rigidité. Grâce aux nervures tronconiques 10 prévues à cet effet, la double paroi inférieure 4-5 ne risque pas de s'affaiser et se trouve ainsi parfaitement remplie.First place the bottom 1 and fill the free space between the side walls 2-3 the bottom walls 4-5 with a concrete-like product in order to ballast and increase its rigidity. Thanks to the frustoconical ribs 10 provided for this purpose, the lower double wall 4-5 is not likely to collapse and is thus perfectly filled.

On réalise ensuite les raccordements nécessaires et on pose par dessus un certain nombre de rehausses telles que 11, jusqu'à atteindre le niveau du sol. La double paroi 12-13 de toutes ces rehausses est également remplie avec du béton, éventuellement armé, l'étanchéité étant assurée par la lèvre intérieure 14 venant en prise dans l'élément inférieur. De préférence, un joint plat, rond ou ovale en élastomère est inséré dans le plan de joint entre les différentes rehausses et également entre le fond et la rehausse située immédiatement au-­dessus, afin d'améliorer l'étanchéité entre l'extérieur et l'intérieur du regard et d'éviter les entrées d'eau provenant de la nappe phréatique ou inversement d'éviter que les effluents polluent l'environnement.The necessary connections are then made and a number of risers such as 11 are placed over them until they reach ground level. The double wall 12-13 of all these extensions is also filled with concrete, possibly reinforced, the seal being ensured by the inner lip 14 engaging in the lower element. Preferably, a flat, round or oval elastomer seal is inserted in the joint plane between the different risers and also between the bottom and the riser located immediately above, in order to improve the seal between the outside and the 'inside the manhole and to avoid the entry of water from the groundwater or vice versa to avoid that the effluents pollute the environment.

Il ne reste plus alors qu'à enterrer le regard ainsi constitué, après avoir posé sur l'élément le plus élevé un couvercle amovible réalisé par exemple en béton armé.It then only remains to bury the manhole thus formed, after having placed on the highest element a removable cover made for example of reinforced concrete.
