Definitions

  • the present invention relates to a structure of waste water well of plastic material.
  • Waste water wells are known, i.e. for black water and soapy water, used as collecting reservoirs, expansion reservoirs, but also as connection receptacles for sewer systems.
  • the waste water wells of known type have box-like shape and are made of concrete, of fiberglass reinforced plastic, or of moulded plastic material.
  • waste water wells in concrete have the drawback of having a high weight that requires a complex and difficult installation, and fo this reason then they are used only when high resistance against mechanical actions is required, waste water wells of plastic material are widespread on the market even if they cannot be used in case resistance against high mechanical actions is required, such as resistance to walking and vehicle transit, since they are not capable of assuring enough mechanical resistance.
  • waste water wells of plastic material some wells are adapted to be easily connected to ducts of different diameter. More in detail, on the sides of the box-like portion of a waste water well tubular concentric portions of different diameter are provided. This way, waste water wells have a certain flexibility since they can be connected to the sewer network system simply connecting at the side surface of the waste water well on a tubular portion having diameter corresponding to that of the duct to which it has to be connected, and cutting away the tubular portions of smaller diameter.
  • this solution can cause the solid material to deposit in the waste water well.
  • the apertures made on the surface of the waste water well for connecting it to the network via the inlet and outlet ducts are, in fact, arranged at different heights. Therefore, the flow of the liquid between the inlet and outlet ducts of the waste water well meeting different levels that are created inside causes the solid material to deposit in determined points. This phenomenon is further enhanced by the box-like structure of the waste water well.
  • the inlet ducts and the outlet ducts of the waste water consist of two respective pluralities of ducts of different diameter having a lowest generatrix substantially at a same distance to the base of the hollow body, said distance being the same for said inlet and outlet ducts.
  • the hollow body and the pluralities of inlet and outlet ducts are made as a single part obtained for injection moulding.
  • the ducts of each plurality can be arranged in such a way that the respective lowest generatrix close to the base of the hollow body that are coincident to one another.
  • the different ducts are arranged all at a same distance from the base of the hollow body. This simplifies remarkably the flow of the waste water towards/away from the hollow body and avoids any accumulation of solid material inside.
  • the cover and the hollow body have mutual engagement means.
  • the cover at the surface that in use is oriented towards the hollow body has a projection adapted to couple with the inner side face of the hollow body.
  • the inner side face of the hollow body has at least one support on which the projection of the cover abuts.
  • a waste water well comprises:
  • the cover can comprise:
  • two next circumferential ribs have a ratio between the respective diameters set between 1.2 and 2.5, advantageously set between 1.4 and 2.0, preferably between 1.6 and 1.8.
  • the circumferential ribs are concentrated in the central portion of the cover and become less frequent towards the periphery. This gives a higher mechanical resistance at the central portion of the cover where, in the presence of mechanical actions, in particular, pushing actions, the maximum flexion is recorded.
  • the hollow body may have a cylindrical shape, or alternatively, polyedric shape.
  • the hollow body at the inner side surface, has beveled edges suitable to assist the outflow of the waste water treated from the recess of said hollow body.
  • the cover can be connected to the hollow body by an interposition duct adapted to engage with said cover and with said hollow body at the end.
  • a waste water well 1 comprises a hollow body 2 and a cover 10, which are made of thermoplastic material and are adapted to sealingly couple to each other.
  • Hollow body 2 comprises a base 6 and a side surface 4 from which four pluralities of ducts protrude 3a-3d having different diameter.
  • each plurality comprises ducts 3a-3d of different diameter arranged in such a way that the element of larger diameter 3d encircles those of smaller diameter 3a-3c.
  • tubular elements 3a-3d of each plurality are arranged according to result close to one another, or overlapped, at a respective generatrix close to base 6.
  • the different pluralities, and therefore the respective ducts 3a-3d are arranged at a same distance from base 6. This particular arrangement allows a high flexibility, for the presence of ducts of different diameter, as well as an optimal efficiency of operation. In operative conditions, the flow of treated waste water does not meet obstacles, i.e. different heights, between the inlet ducts and the outlet ducts, and can then outflow freely from the waste water well 1.
  • hollow body 2 may have cylindrical shape ( figure 1 ) or, alternatively, polyedric shape with beveled edges at the inner side face ( figures 9 and 10 ).
  • the surface 4 of hollow body 2 is cut at each plurality of tubular elements, for removing the tubular elements of smaller diameter than the desired diameter.
  • waste water well 1 is connected by means of inlet ducts 80-82 to three different users at the plurality 3'-3''' of ducts.
  • the waste water flow then from waste water well 1 towards the sewer network system through a duct 83 connected to hollow body 2 at the plurality of ducts 3 iv .
  • the particular arrangement of tubular elements 3a-3d allows to arrange the ducts 80-83 substantially on a same plane ⁇ ( figure 4 ).
  • cover 10 and hollow body 2 are coupled through mutual engagement means.
  • cover 10, at surface 12 that in use is oriented towards hollow body 2 has a projection 35 adapted to couple with the inner side face of hollow body 2.
  • a seal 5 connecting hollow body 2 and the projection 35 ensures then the necessary tightness between the two bodies.
  • the projection 35 of the cover 10 is, in use, arranged abutting on supports 7, for example 4 arranged at 90°, protruding towards the inside of waste water well 1 starting from the inner surface of hollow body 2.
  • hollow body 2' with polyedric shape
  • at an end that adapted to couple with the cover a containing neck 14 can be provided. More in detail, the walls 17 of hollow body 2' protrude from the neck 14 towards the inside of the waste water well 1, whereby the projection 35 of the cover 10 can abut on them.
  • the cover 10 has a portion 13 that extends beyond the side surface 4 of hollow body 2.
  • portion 13 in use is arranged on a support, for example a concrete casting 100, on which large part of the mechanical actions are loaded to which the waste water well is subject 1. Therefore, it is not necessary to provide particular stiffening structure for base 6 of hollow body 2. This remarkably simplifies the production process for hollow body 2 and, in particular, the shape of the mould from which it is obtained.
  • the cover 10 is connected to the body 2 by a duct 85. More in detail, the duct 85 at its end has mutual engagement means with the cover 10 and with hollow body 2.
  • the cover 10 is made of two parts ( figure 5 ). In detail, it comprises a portion 30 of engagement with hollow body 2, and a stiffening portion 20 adapted to couple with it, for example with a click engagement. Between engagement portion 30 and stiffening portion 20 a seal 15 is arranged.
  • Stiff portion 20 at the surface that faces portion 30 is equipped with a plurality of circumferential concentric ribs, for example 5 51-55, concentrated at the central portion of the cover 10 and more sparse towards the periphery.
  • two next circumferential ribs 51-52, 52-53, 53-54 and 54-55 have a ratio between the respective diameters set between 1.2 and 2.5, for example 1.8. this gives a higher mechanical resistance at the central portion of cover 10 where in the presence of mechanical actions, in particular, pushing actions, the maximum flexion is recorded ( figure 8 ).
  • a plurality of radial ribs 60 is provided between two next circumferential ribs 51-55 furthermore.
  • hollow body 2 has inside a shaped surface suitable to assist the outflow of the waste water treated by the waste water well 1.
