Une telle structure de puits est connue de WO-A-9748859. La structure de puits est destinée à être encastrée dans le sous-sol, de façon que l'ouverture d'accès avec couvercle Such a well structure is known from WO-A-9748859. The well structure is intended to be embedded in the basement, so that the access opening with cover
vienne se placer dans le plan du pavage. come and place yourself in the plane of the paving.
Selon le lieu d'implantation, la structure de puits peut être exposée à des charges plus ou moins grandes, en particulier des charges provenant de la circulation. L'objectif de Depending on the location, the well structure may be exposed to more or less large loads, in particular loads from traffic. The objective of
l'invention est de fournir une structure de puits résistant mieux à de telles charges. the invention is to provide a well structure which better withstands such loads.
Cet objectif est atteint en ce que le logement possède aussi des nervures de soutènement s'étendant entre le fond d'appui et l'ouverture d'accès, et coupant ou croisant This objective is achieved in that the housing also has support ribs extending between the support base and the access opening, and cutting or crossing
les nervures circonférentielles.the circumferential ribs.
La combinaison des nervures circonférentielles et des nervures verticales fournit une résistance à ce point élevée, que même le matériau plastique ne cède pas et est capable de supporter les charges de la circulation. En particulier, les nervures de soutènement peuvent former un ensemble avec le logement, et, de préférence, elles font saillie vers l'extérieur, en offrant une coupe transversale en forme de V. Les nervures de soutènement peuvent s'étendre entre un appui pour le couvercle s'étendant autour de l'ouverture d'accès, et le fond. En raison de la solidité requise, le fond The combination of the circumferential ribs and the vertical ribs provides such a high resistance, that even the plastic material does not yield and is able to support the traffic loads. In particular, the retaining ribs can form an assembly with the housing, and, preferably, they project outwards, offering a V-shaped cross section. The retaining ribs can extend between a support for the cover extending around the access opening, and the bottom. Due to the required strength, the bottom
peut posséder un panneau bombé vers l'extérieur. may have a curved panel to the outside.
Le couvercle peut présenter un panneau bombé vers l'extérieur, entouré d'un bord The cover may have an outwardly curved panel, surrounded by an edge
d'appui, qui peut s'appuyer sur le logement, autour de l'ouverture d'accès de celui-ci. support, which can be supported on the housing, around the access opening thereof.
Dans une forme d'exécution particulièrement robuste, le couvercle est à double paroi, et possède un panneau extérieur de même qu'un panneau intérieur bombés vers l'extérieur. Le panneau bombé intérieur s'étend jusque dans l'ouverture d'accès du logement. Les deux panneaux bombés du couvercle sont rattachés réciproquement dans la partie qui se trouve à l'intérieur du bord d'appui. La liaison entre les panneaux bombés du couvercle peut être réalisée de différentes façons, par exemple au moyen de cloisons. On préférera une forme d'exécution, dans laquelle le panneau bombé intérieur a au moins une saillie creuse qui s'étend jusqu'au panneau bombé extérieur. Les saillies peuvent être In a particularly robust embodiment, the cover is double walled, and has an outer panel as well as an inner panel curved outward. The interior curved panel extends into the access opening of the housing. The two curved panels of the cover are reciprocally attached in the part which is inside the support edge. The connection between the curved panels of the cover can be achieved in different ways, for example by means of partitions. An embodiment is preferred, in which the inner curved panel has at least one hollow projection which extends to the outer curved panel. The protrusions can be
coniques, la pointe du cône étant rattachée au panneau bombé extérieur. conical, the tip of the cone being attached to the curved exterior panel.
