Definitions
- the subject of the present invention is a block of juxtaposed sheets and a structure for a water retention tank, formed from a set of these blocks, intended for various uses, for example as an underground basin for retaining rainwater during very heavy rain, this structure then being connected to a collector network of water supply and drainage.
- porous material such as car parks, roadways, sports grounds, etc., integrating the storage of rainwater in a porous material into their structure, are part of these solutions, and are called “reservoir structures”.
- the porous material then has at least two functions: hydraulic and mechanical, and is generally located below the level of the natural ground. This makes it easy to collect runoff water.
- the object of the invention is to propose a tank structure which is simple and quick to set up, the cost price of which is therefore considerably reduced compared with that of the known structure below. on it, and which cannot be clogged with sand or debris.
- the block of identical juxtaposed sheets intended for a structure of a water retaining tank, is characterized in that the sheets are profiled so as to delimit between them a set of longitudinal cells and d 'transverse cells which establish communication between the longitudinal cells, the latter being open at their opposite ends.
- the tank structure according to the invention comprises at least one layer of such juxtaposed blocks, arranged so that the longitudinal cells extend vertically for water storage, and that the transverse cells extend horizontally for the horizontal circulation of water between inlet and outlet collectors.
- the horizontal cells are distributed over the greater part of the length of the vertical cells, that is to say blocks, and ensure the drainage of water practically from the top to the bottom of the blocks, tan ⁇ dis that the vertical storage cells ensure the mechanical strength of the assembly.
- this structure is combined to simultaneously fulfill the functions of drainage and storage of water, then of vertical runoff of water, considerably reduces the labor required, as well as the cost price of the structure itself. It is advantageously carried out in one a suitable plastic material, such as, for example, polystyrene, polypropylene or polyvinyl chloride, or any other thermoplastic material.
- a suitable plastic material such as, for example, polystyrene, polypropylene or polyvinyl chloride, or any other thermoplastic material.
- Figure 1 is a schematic elevational view of an embodiment of the reservoir structure according to the invention, in which this structure is part of an underground water retention basin.
- Figure 2 is a perspective view of a building block of the honeycomb structure according to the invention.
- Figure 3 is an elevational view of the cellular structure elé ⁇ ment of Fig.2.
- the structure of the water retention tank shown in Fig. 1 includes, from the bottom up:
- a waterproof membrane 1 a cellular part 3 formed of three superimposed layers 3.1, 3.2 and 3.3, a geotex ⁇ tile 4, a layer of fill 5 (or cuttings used as fill), and finally a surface layer 6 of topsoil .
- the honeycomb structure (3) communicates laterally with collectors 7 for supply and 8 for evacuating the water accumulated in this structure, at the ends mites from which vertical ventilation tubes 9, 11 are provided, which open into the peripheral zone of the tank, into the collectors 7 and 8.
- the wall 7a of the collector 7 contiguous to the vertical end face of the structure 3 is perforated over practically its entire height, while the discharge collector 8 is pierced with openings at the level of the lower part of the structure 3.
- the structure 3 consists of a set of blocks 12 with juxtaposed cells (Fig. 2 and 3).
- Each element or block 12 is formed by the assembly of a series of identical sheets 13 ... 18 suitably profiled so as to present a succession of straight bos ⁇ wise lines 19 and rectilinear hollow 21 delimited by two bosses 19 consecutive.
- These recesses or grooves 21 and the bosses 19 are alternated in both transverse and longitudinal directions so as to be staggered.
- a boss 19 is located between two recesses 21, as well as in the transverse direction.
- Inclined plates 23 form the transition zones between the bosses 19 and the recesses 21.
- the tops of the bosses 19 form rectilinear plates 19a, alternating on each side of the median plane of the sheet 13, ... 18.
- Two sheets are assembled by gluing or welding their bosses 19 facing each other by their plates 19a, delimiting between them these and the recesses 21 of the longitudinal cells 22.
- the succession of plates 23 of two sheets joined together between these two sheets delimits transverse cells 10 perpendicular to the longitudi ⁇ nal cells 22, and whose section is in rhombus. These cells 10 communicate with the successive cells 22, thus interconnected and whose opposite ends, green, form the end faces of the block 12.
- the lengths of the successive zones arranged in staggered rows thus produced can be variable, as well as the number of successive zones for the same element 12.
- each sheet 13 ... of a block 12 of sheets 13-18 comprises three longitudinal zones A, B, C, in which the bosses 19 and the recesses 21 are alternated in quin ⁇ conce, the central zone B being substantially twice the length of that of each of the two end zones A and C. These zones are separated by parallel rows of transverse cells 10.
- the edges of the sheets delimit between them cells 22 open longitudinally (FIG. 2) in zones A and C due to the spacing of these edges (for example 17a and 18a).
- these edges are contiguous and therefore separate the open cells from zones A and C.
- the number of cells 10 can be increased to favor the drainage function over the retained water storage function, the extreme cells 10 then being close to the opposite ends of the blocks 12.
- this structure is produced in three superposed layers: a first layer 3.1 of height hl, equal by example to that (A + B + C) of an element 12; then placed on the first layer 3.1, a second layer 3.2 height h2 less than that hl of the first layer 3.1.
- the second layer 3.2 is obtained by uncovering a series of blocks 12, identical to those of the first layer 3.1 and of the lower structure 2, below its upper cells 10 at a level (FIG. 3) close to these last.
- the height h2 e slightly less than A + B.
- the third layer 3.3 placed in abutment on the intermediate layer 3.2 is formed by the juxtaposition of a set of truncated elements 20 constituting the upper ends cut above the level K of the elements 12, e returned by 180 °.
- the cells 10 of truncated elements 20 are located just below the upper surface of the structure 3.
- the intake manifold 7 may be located at a location other than lateral to the reservoir structure 3, for example in a median zone thereof.
- the second wall of the collector 7 is of course suitably perforated like the wall 7a and a second evacuation collector 8 associated is necessary.
- this tank structure has the following:
- the horizontal cells 10 accelerate the filling of the tank thanks to the communication they establish between the vertical cells 22.
- the water drainage is ensured over almost the entire height of the structure 3, thanks to the removal of the structure classic lower drainage. This eliminates the thickness of this draining structure, and therefore the corresponding earthworks.
- the sheets 13, 14 ..., produced by thermoforming of plastic material can have a variable thickness, for example 1mm, which makes it possible to adjust their mechanical strength as well as possible (advantage which cannot be obtained with structures manufactured by extrusion ). Indeed, a mass placed on the ground above the reservoir structure 3 exerts on the successive layers 3.3, 3.2, 3.1 decreasing pressures from top to bottom. As a result, the mechanical strength of the different layers can be adjusted to the pressures experienced. This is how the thickness of the upper layer 3.3 will be greater than that of the intermediate layer 3.2, which itself will be greater than that of the lower layer 3.1. This reduction in thickness lightens the assembly and therefore facilitates its installation.
- the height of the lowest horizontal cells 10 can advantageously be relatively high. Indeed, this then makes it possible to collect in the lower ends of the vertical cells 22 the sand entrained by the water. This sand can not clog the lowest horizontal cells 10, unlike known drainage structures, so that the drainage function is still ensured, despite the accumulated sand.
- the example of the structure (2,3) of Fig.l is not limiting, the vertical structure 3 can be made of a single layer formed of elements (such as 12 for example), of suitable height, or several sub-layers of identical or different heights.
- the corresponding elepipedic block blocks 12 can have variable dimensions, suitable for each use envisaged.
- these seemingly elepipedic blocks can be used to rest on any of their faces, always having horizontal drainage cells and other vertical storage cells. It is also possible, in at least part of the blocks 12, to orient every other sheet with its bosses 19 perpendicular to the bosses of the two adjoining sheets to which it is fixed. This agency surround improves the drainage function.
- the leaves can also be completely or partially perforated to increase the drainage efficiency.
- the tank structure according to the invention is susceptible of numerous applications, among which the following will be cited:
- the structure as a porous pavement: after direct infiltration through the pavement layers (draining asphalt and serious draining), the water is stored in the reservoir structure according to the invention, then returned, either by infiltration into the ground, either by conduit in the network.
