Definitions

  • the present invention relates to the field of town planning and rainwater sanitation and it concerns more particularly a reservoir structure intended in particular for the realization of tank roads in Urban.
  • a water reservoir constituted by a set of parallelepipedic blocks made of plastic (for example polypropylene or any equivalent thermoplastic material) forming a honeycomb honeycomb structure and which can be arranged under green spaces or areas subject to low permanent loads (eg playgrounds or sports complexes) or under urban roads subject to very low traffic.
  • plastic for example polypropylene or any equivalent thermoplastic material
  • this structure proves poorly suited for use under heavy traffic traffic under heavy load and for which the use of a such structure could only be done under a foundation layer important.
  • manufacturing and implementation costs relatively high.
  • a tank structure for storage and the containment of rain runoff comprising a set hollow concrete elements arranged in bulk, randomly, so as to have a vacuum index greater than 50%.
  • these hollow concrete elements are elements each having a volume not exceeding 1 dm 3 . They may have a prismatic or cylindrical shape, and a compressive strength of between 30 and 65 MPa.
  • the concrete forming these hollow elements is cement-based, with or without fibers (for example polypropylene), or resin-based.
  • said set of elements hollow concrete is covered by an equalizing layer formed of a coarse gravel size of aggregates between 20 and 50 mm.
  • This equalization layer and the set of hollow concrete elements are surrounded by a geotextile to protect them from intrusions of fine elements.
  • the present invention also relates to an urban roadway or any other buried or open structure including such a reservoir structure, whether they are parking lots, infiltration wells, or storage ditches.
  • Figure 1 schematically illustrates a reservoir structure according to the invention implemented at an urban roadway.
  • This roadway 20 comprises, from its upper surface until lower level of the soil, a layer 22 of porous coating, such as a draining asphalt or a set of permeable concrete pavers constituting the raceway for vehicles, a superficial layer of shape 23 (also called laying bed) a few centimeters thick (typically 3 to 5 cm) consisting for example of a layer of sand or gravel of very small dimensions, an equalization layer 24 formed grossly coarse (that is to say, expurgated from its finest constituents) about a few centimeters thick and having a dimension of aggregates between 20 and 50 mm, and a storage area (layer of retention 26) constituting the reservoir structure itself and comprising a particular type of honeycomb products formed of concrete elements.
  • a geotextile 28 surrounds the porous material 26 and the leveling layer 24 to prevent any intrusions of fine elements from the soil 30, the form or side embankments and reinforce the cohesion of the whole.
  • FIG. 1 A second example of realization of an urban pavement with of a reservoir structure according to the invention is illustrated in FIG.
  • This roadway 40 comprises, as before, a layer 42 coating material constituting the rolling track for vehicles, a equalization layer 44 and a retention layer 46 forming the reservoir structure.
  • the coating layer 42 is an impermeable layer formed of a compact coating. Since then, rain runoff can no longer flow to the ground 30 through of the coating 42, it is provided on each side of the gutter channel and drain mouths 52 allowing infiltration of water to the retention layer 46. This infiltration will preferably be carried out in multiple injection points, possibly extended by a network of drains ensuring the distribution of water in the structure.
  • the ground 30 as well as the lateral embankments 50 are covered with an impermeable geomembrane 54 constituting a reservoir waterproof that prevents any natural infiltration into the soil, the evacuation of the water is then effected by means of drainage drains 56 placed on the floor at the bottom of the structure (at the bottom of the tank), and for example either side of the retention layer 46.
  • drainage drains 56 placed on the floor at the bottom of the structure (at the bottom of the tank), and for example either side of the retention layer 46.
  • These drains can be connected downstream to a collection view (not shown) equipped with a debit regulator.
  • Unrepresented purification devices (basket, settling mouth, siphoid device, laminar decanter) will be obviously also provided for the right of the mouths drains to limit the entries of all pollutions in the structure.
  • the retention layer 26, 46 forming the reservoir structure itself is constituted, at a thickness of at least 20 cm (the thickness will depend on the volume of water to be stored), multiple concrete elements, identical or not, randomly distributed so as to form a compact assembly with a high porosity greater than 50%, typically from 50% to 60%, ie a retention of 500 to 600 liters of water per m 3 , much higher than that obtained with a simple Ordinary coarse gravel layer for which this so-called vacuum void porosity is close to 35%.
  • Each element is in the form of a small prismatic or cylindrical hollow element of concrete based on cement or resin having a mean compressive strength of between 30 and 65 MPa.
  • the constituent concrete may be cavernous or not and provided or not with fibers (for example polypropylene).
  • this element has a volume ⁇ 1dm 3 with dimensions of between 40 and 100 mm, for its height and external dimension, and between 20 and 60 mm for its internal dimension.
  • FIG. 3 shows a first example of a concrete element 60 having a hollow structure with a circular section (cylindrical structure)
  • FIG. 4 shows a second example of a concrete element 62 having a hollow structure with a polygonal section, in particular hexagonal section (structure right prismatic).
  • the operation of the reservoir structure is as follows. During violent rainfall, the rainwater will be drained towards the reservoir structure 26, 46 through the coating 22 or by means of the gutters or gullies 52. These waters will gradually fill this structure by filling the existing void (chasing the air that was there) between the multiple elements of concrete and in these elements themselves, thus storing the accumulated water. When the rain stops and the runoff has ceased, the structure will gradually empty up to complete emptying. The leakage flow will be conditioned either by the capacity infiltration of the natural soil 30 either by a downstream regulating device (no represent).
