Manhole cover having at least one operating housing (5) on its upper face (4). A hole (7) of oblique axis X-X is pierced in the upper face (4) of the cover and opens into the operating housing (5) tangentially relative to its bottom. <IMAGE>

Description

La présente invention a pour objet un tampon de regard de chaussée étanche.The present invention relates to a sealed pavement manhole cover.

Les tampons de regards de chaussée, qu'ils soient circulaires, carrés, triangulaires ou autres, présentent souvent sur leur face inférieure des nervures de rigidification permettant une diminution sensible de leur épaisseur et de leur poids.Pavement manhole covers, whether circular, square, triangular or other, often have stiffening ribs on their underside allowing a substantial reduction in their thickness and their weight.

Ils présentent également sur leur face supérieure au moins un boîtier de manoeuvre pour le passage d'un outil, un pied de biche dans la plupart des cas, permettant au manipulateur de désolidariser le tampon de son cadre pour ouvrir le regard et accéder à la cheminée de visite qu'il recouvre.They also have on their upper face at least one operating box for the passage of a tool, a crowbar in most cases, allowing the manipulator to separate the pad from its frame to open the manhole and access the chimney. of visit that it covers.

Lors de la fabrication des tampons, après les opérations de fonderie, ceux-ci sont revêtus de produits les protégeant contre les chocs et leur rendant un aspect agréable. Très souvent, on leur fait subir une opération de goudronnage ou de peinture.During the manufacture of the pads, after the foundry operations, they are coated with products protecting them against impacts and making them look pleasant. Very often, they are subjected to a tarring or painting operation.

L'inconvénient de ce type de tampon réside dans le fait qu'après son goudronnage ou sa mise en peinture, quelle que soit sa position de séchage, certains endroits présentent des amas de goudron ou de peinture qui ne peuvent s'écouler, très souvent au fond du boîtier de manoeuvre.The disadvantage of this type of pad lies in the fact that after it has been tarred or painted, whatever its drying position, certain places have heaps of tar or paint which very often cannot flow at the bottom of the control box.

Les regards de chaussée étant destiné à être posé sur la route ou le trottoir, ils sont soumis aux intempéries et, un grand nombre de saletés et de poussières, amenées par les intempéries ou par les passages des véhicules ou des piétons, pénètrent dans les interstices, en particulier dans le boîtier de manoeuvre.The manholes are intended to be placed on the road or the sidewalk, they are subject to the weather and, a large number of dirt and dust, brought by the weather or by the passage of vehicles or pedestrians, penetrate into the interstices , in particular in the operating box.

Ainsi, lors de l'ouverture du tampon, l'introduction de l'outil de manoeuvre dans le boîtier compacte les poussières et, petit à petit, il se forme un bouchon très dur empêchant l'introduction de l'outil de manoeuvre.Thus, when the tampon is opened, the introduction of the operating tool into the housing compacts the dust and, little by little, it forms a very hard plug preventing the introduction of the operating tool.

Il est connu d'utiliser des tampons de regards de chaussée dont le font du boîtier de manoeuvre est percé d'un trou débouchant dans la face inférieure du tampon.It is known practice to use manhole plugs, the opening of the operating housing of which is pierced with a hole opening in the underside of the plug.

Ainsi, on évite tout amas de goudron ou de peinture et tout problème de compactage des poussières.This avoids any accumulation of tar or paint and any problem of dust compaction.

Mais l'inconvénient de ce type de regard est qu'il n'est plus étanche.But the drawback of this type of look is that it is no longer waterproof.

La présente invention concerne un tampon de regard de chaussée permettant de s'affranchir de ces inconvénients.The present invention relates to a pavement manhole cover enabling these drawbacks to be overcome.

La présente invention a plus particulièrement pour objet un tampon de regard de chaussé présentant au moins un boîtier de manoeuvre sur sa face supérieure, dans lequel un trou d'axe X-X oblique est percé sur la face supérieure du tampon, débouchant dans le boîtier de manoeuvre tangentiellement à son fond.The present invention more particularly relates to a manhole cover having at least one maneuvering box on its upper face, in which a hole of oblique axis XX is drilled on the upper face of the buffer, opening into the maneuvering box. tangentially to its bottom.

D'autres caractéristiques et avantages apparaîtront au cours de la description qui va suivre, donnée uniquement à titre d'exemple, faite en référence aux dessins annexés et dans lesquels :

  • la Fig. 1 est une vue en coupe d'un tampon muni d'un boîtier de manoeuvre de type connu, pendant l'opération de séchage ;
  • la Fig. 2 est une vue du dessus d'un tampon selon l'invention ;
  • la Fig. 3 est une vue en coupe d'un tampon selon l'invention, pendant l'opération de séchage.
Other characteristics and advantages will appear during the description which follows, given solely by way of example, made with reference to the appended drawings and in which:
  • Fig. 1 is a sectional view of a pad provided with an operating box of known type, during the drying operation;
  • Fig. 2 is a top view of a tampon according to the invention;
  • Fig. 3 is a sectional view of a tampon according to the invention, during the drying operation.

Les tampons de regard de chaussée présentent sur leur face inférieure 1 une série de nervures de rigidification 2 délimitant ainsi des cavités 3.The manhole covers have on their lower face 1 a series of stiffening ribs 2 thus delimiting cavities 3.

Leur face supérieure 4 présente au moins un boîtier de manoeuvre 5 destiné à l'introduction d'un outil permettant l'ouverture du tampon.Their upper face 4 has at least one operating unit 5 intended for the introduction of a tool allowing the opening of the tampon.

Comme on le voit Fig. 1, la configuration des cavités 3 impose un séchage en position oblique afin qu'aucun amas de goudron ou peinture ne stagne dans lesdites cavités 3. Or dans cette position, étant donné que le boîtier de manoeuvre 5 forme également une cavité sur la face supérieure du tampon, un amas de goudron 6 s'y forme souvent.As seen in Fig. 1, the configuration of the cavities 3 requires drying in an oblique position so that no mass of tar or paint stagnates in said cavities 3. However, in this position, since the operating housing 5 also forms a cavity on the upper face of buffer, a pile of tar 6 often forms there.

Le tampon selon l'invention présente sur sa face supérieure 4 un trou d'axe X-X oblique débouchant dans le fond du boîtier de manoeuvre 5 tangentiellement à son fond. Le trou 7 fait un angle α avec la face supérieure 4 du tampon compris entre 30 et 70°.The pad according to the invention has on its upper face 4 an oblique axis axis X-X opening into the bottom of the operating housing 5 tangentially to its bottom. The hole 7 makes an angle α with the upper face 4 of the buffer between 30 and 70 °.

Ainsi, lorsque le tampon est en position oblique de séchage permettant au surplus de goudron ou de peinture de s'écouler des cavités 3, comme représenté Fig. 3, l'éventuel surplus de goudron ou de peinture présent dans le boîtier de manoeuvre s'écoule par le trou 7 qui se trouve dans cette position du tampon légèrement incliné par rapport à l'horizontal.Thus, when the pad is in the oblique drying position allowing the excess tar or paint to flow from the cavities 3, as shown in FIG. 3, any excess tar or paint present in the control unit flows through the hole 7 which is in this position of the pad slightly inclined relative to the horizontal.

Une telle configuration du boîtier de manoeuvre 5 permet également d'éviter le compactage des poussières dans le fond dudit boîtier. En effet, lors de l'introduction de l'outil de manoeuvre, les poussières qui se sont déposées dans le boîtier sont poussées vers le trou 7 et évacuées vers l'extérieur.Such a configuration of the operating box 5 also makes it possible to avoid the compaction of the dust in the bottom of said box. Indeed, during the introduction of the operating tool, the dust which is deposited in the housing is pushed towards the hole 7 and evacuated towards the outside.
