On connaît un fond de regard en matière plastique & 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 We know a plastic manhole & double wall, in which the space between the two walls is intended to receive concrete or a similar product during its installation on the site, in order to increase its weight and its resistance mechanical. However, it was found that such a manhole did not have sufficient rigidity at its lower part, which could

- la figure 6 est une vue en coupe suivant la ligne VI-VI de la figure 5. - 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 ou 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 The manhole shown in Figures 1 to 4 is made in one piece of plastic, for example polyethylene, by rotational molding or the like. It consists of a body 1 of cylindrical section with double wall, open at its upper part, and thus comprises a double side wall 2-3
et une double paroi inférieure 4-5. and a lower double 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 In the double side wall 2-3 are formed circular openings 6 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 inner side by a veil of material 8 that it will

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 Furthermore, the double side wall 2-3 is provided in its upper part with a number of ribs 9 forming spacers and which ensure
ainsi la rigidité de cette paroi sans l'obturer complètement. thus the rigidity of this wall without completely sealing it off.
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. 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 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. The manhole cover which has just been described is associated with one or more extensions such as that shown at 11 on the. Figures 5 and 6, to form a complete look. This extension essentially consists of a cylindrical plastic body open at both ends and has
2 6 2 1 3392 6 2 1 339
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. 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 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. In the particular embodiment described here, the extension is also provided with three openings 16, similar to the openings 6 in the manhole 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 formant entretoises, qui assurent la rigidité de la double paroi latérale 12- 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'effectue de la manière suivante: On pose d'abord le fond 1 et on remplit l'espace libre entre les parois latérales 2-3 et 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 13. The installation of the manhole in accordance with the invention is carried out in the following manner: First placing the bottom 1 and filling the free space between the side walls 2-3 and the bottom walls 4-5 with a concrete product in order to ballast it 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
et se trouve ainsi parfaitement remplie. and is thus perfectly filled.
On réalise ensuite les raccordements nécessaires et on pose par dessus Then we make the necessary connections and we put on top
un certain nombre de rehausses telles que 11, Jusqu'à atteindre le niveau du sol. a number of elevations such as 11, until reaching ground level.
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 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 joint is inserted in the joint plane between the different
rehausses et également entre le fond et la rehausse située immédiatement au- risers and also between the bottom and the riser located immediately above
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 above, in order to improve the seal between the outside and the inside of the manhole and to avoid the entry of water from the groundwater or vice versa
d'éviter que les effluents polluent l'environnement. prevent effluents from polluting 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 It then only remains to bury the manhole thus constituted, after having placed on the highest element a removable cover produced for example
en béton armé.in reinforced concrete.
