Definitions
- the present invention relates to a sealed pavement manhole cover.
- 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.
- the manholes are intended to be placed on the road or the sidewalk, they are exposed to the weather and, a large number of dirt and dust, brought by the weather or by the passage of vehicles or pedestrians, enter the interstices , in particular in the operating box.
- 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.
- the present invention relates to a pavement manhole cover enabling these drawbacks to be overcome.
- 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.
- the manhole covers have on their lower face 1 a series of stiffening ribs 2 thus delimiting cavities 3.
- Their upper face 4 has at least one operating unit 5 intended for the introduction of a tool allowing the opening of the tampon.
- 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.
- the operating housing 5 also forms a cavity on the upper face of buffer, a pile of tar 6 often forms there.
- 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 ⁇ with the upper face 4 of the buffer between 30 and 70 °.
- 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.
- 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.
