Definitions

  • the present invention relates to a three-dimensional unitary element intended to fill a buried basin for infiltration, retention and / or storage of rainwater.
  • the invention relates more particularly to a spherical three-dimensional unitary element formed of plastic elements which can be pre-assembled in the factory or assembled on site.
  • the depositor is already marketing a three-dimensional structure called RAUSIKKO BOX designed for the retention and return of rainwater either by infiltration or limited or regulated flow.
  • This solution consists in using stackable plastic platforms for their transport, and which are assembled together in order to form a volume comprising numerous hollow spaces. It is advantageously a system which can be implemented in a flexible and durable manner in all conceivable configurations.
  • These self-fixing modules make it possible to meet all site constraints: high modularity, high mechanical resistance and easy operation of the system.
  • the known plastic platforms are very bulky for their transport, despite their stackable nature. The assembly time required to assemble these platforms is also of little benefit.
  • the assembly of the three-dimensional structure RAUSIKKO BOX requires a perfectly flat surface for its installation, which results in long and expensive earthworks.
  • the object of the present invention therefore aims to overcome the drawbacks of the prior art by proposing a new three-dimensional unitary element intended to fill a rainwater retention basin.

  • the basin it is not necessary for the basin to have a flat bottom and its shape can be arbitrary, because the mass of three-dimensional unit elements of the invention adapts itself to the shape of said basin.
  • each three-dimensional unitary element Made up of two hollow half-spheres assembled by means of a circular fixing piece interposed between the two half-spheres, each three-dimensional unitary element can be transported in the dissociated state to reduce its bulk. It can also be assembled in the factory and transported assembled so that it can be quickly and easily dumped in bulk on site.
  • the fastener advantageously reinforces the rigidity of the whole of the three-dimensional unitary element.
  • the whole of the three-dimensional unitary element of the invention is very light and makes it possible to create a large void volume intended for the infiltration, retention and / or storage of rainwater.
  • each hemisphere comprises a hollow central cone comprising a base of larger diameter from which extends a tapered distal portion, said cone extending towards the inside of the hemisphere such that when the two hemispheres are assembled with the fastener, the tapered distal parts of each of the two cones are resting, either in mutual contact or against the fastener, substantially in the center of the three-dimensional unitary element.
  • central cones advantageously reinforce the compressive strength of the whole of the three-dimensional unitary element of the invention in the axis of the cones.
  • each hemisphere of the invention is in one piece therewith, thus each hemisphere of the invention can be manufactured by molding with its central cone. .
  • each hemisphere comprises an annular part on the periphery delimiting its open face, this annular part being in one piece with the hemisphere.
  • This annular part is advantageously useful for assembling the two hollow half-spheres and reinforces the compressive strength of the whole of the three-dimensional unitary element of the invention in the plane of the fixing part.
  • each hemisphere is secured to the annular part by reinforcing ribs which extend radially from the central cone. These reinforcing ribs reinforce the overall strength of each hemisphere while allowing each hemisphere to have numerous through openings.
  • the total external surface of the through openings of the two hollow hemispheres represents more than 50%, preferably more than 70% and more preferably more than 90% of the overall external surface of the three-dimensional unitary element.

  • the two hemispheres and the fixing part are assembled by clipping, which allows them to be assembled quickly and easily.
  • the fixing piece comprises at least two pairs of clipping lugs on its outer periphery, each pair of clipping lugs being provided to grip the annular parts of the hemispheres when these are mutually assembled with the fastener.
  • This type of clipping advantageously makes it possible to prevent the hemispheres from accidentally becoming detached from the fixing part.
  • the external diameter of the fixing part is substantially equal to the internal diameter of the annular part of each hemisphere.
  • the fastener is located inside the sphere formed by the assembly of two hemispheres and the presence of the fastener against the internal diameter of the hemispheres further reinforces the compressive strength of those. -this.
  • the fixing part comprises a central part secured to the outer periphery by radial reinforcing structures which extend radially from said central part.
