Definitions

  • 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.
  • 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 see for example DE-U-8 608 182.
  • 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.
  • these recesses are of frustoconical shape and the top of the recesses is an integral part of the inner bottom wall of the manhole.
  • the two bottom bottom walls remain perfectly spaced from each other, providing a space in which the concrete can be introduced without any difficulty.
  • the manhole bottom has a circular section.
  • extensions 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.
  • a flat, round or oval elastomer seal is inserted in the plane of the joint between the riser and the element located immediately below.
  • the extensions have lateral openings for connecting additional fluid inlets.
  • 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 double-walled section, open at its upper part, and thus comprises a double side wall 2-3 and a double lower wall 4-5.
  • 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.
  • four large diameter and two smaller openings are provided which are located at a higher level, as illustrated in FIG. 3.
  • 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.
  • 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.
  • the rigidity of the lower double wall 4-5 is ensured by recesses 10 formed in the outer wall 4 and which form reinforcing ribs.
  • 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.
  • the top of said frustoconical recesses here forms an integral part of the interior wall 5.
  • said tops could also simply bear against the interior 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 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.
  • 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 forming spacers, which ensure the rigidity of the double side wall 12-13.
  • 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.
  • 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.
