Definitions
- the present invention relates to a modular drainage block intended to drain the soil, in general, and around buildings and dwellings, in particular.
- Publication DE-A-22 07 216 describes a monobloc drainage block of square section, crossed by a central and longitudinal collecting duct. It is made of a granular material offering very restricted passages for drainage water, thus not allowing effective drainage. In addition, no device is provided for directing the drainage water in the direction of the collecting duct, therefore a part is evacuated in the embankment.
- the publication US-A-3,440,823 describes a drainage device comprising two separate parts: an inverted V-shaped drainage pipe placed on a waterproof sole. The conduit only has very few lateral channels provided on the edges of the V, clearly insufficient to capture drainage water.
- this inverted V shape does not offer sufficient resistance to crushing due to the weight of the embankments.
- the publication NL-A-7 211 660 describes a drainage block crossed by a central and longitudinal collecting duct, this block being limited to the collection of rainwater in a gutter, since it only comprises openings arranged in the top part.
- the present invention aims to provide this solution by proposing an efficient, practical, easy-to-use drainage block capable of effectively capturing and discharging drainage water.
- the invention relates to a modular drainage block, characterized in that it comprises an elongated body, crossed by a longitudinal collecting duct, and comprising runoff passages opening on the peripheral walls of said body and opening into said collecting duct, these runoff passages being arranged to allow the circulation of drainage water by gravity in the direction of said collecting duct, in that it comprises connection means arranged to assemble two consecutive drainage blocks and in that it has a water permeable outer shell.
- the runoff passages may be constituted by peripheral grooves opening into said collecting duct by transverse channels, transverse channels extending from said peripheral walls to said collecting duct, peripheral baffles opening into said collecting duct by transverse channels or even the interstices of a porous structure forming said body.
- the connection means comprise a sleeve separate from said body, having external dimensions at most equal to the internal dimensions of said collecting duct, this sleeve being intended to fit into the ends opposite the collecting pipes of two consecutive drainage blocks.
- connection means may comprise a sleeve integrated into said body, arranged as an extension of one of the ends of the collecting duct and arranged to form a male part, the other end of the collecting duct being arranged to form a female part intended to receive the male part of an adjacent drainage block.
- connection means also comprise at least one lateral opening provided in said body at the same level as said collecting duct, this lateral opening having dimensions substantially equal to those of said collecting duct, opening into the latter, and being arranged to receive said sleeve intended to assemble at right angles two consecutive drainage blocks.
- the outer envelope consists of a fabric made of a geotextile material, this fabric being wrapped around said body and being longer on one side so as to partially cover the following drainage block.
- the body can be made of an impermeable material chosen from the group comprising at least polystyrene, polyvinyl chloride, concrete, synthetic resin and any synthetic material molded or extruded.
- the body can also be made of a water-permeable material chosen from the group comprising at least expanded polystyrene and any synthetic material. structured or foamed.
- the body may comprise a sealed zone disposed below the collecting duct and constituted by a sole made of impermeable material incorporated in or under said body.
- the collecting duct can also include a sealed inner envelope, if necessary.
- FIGS. 5A and 5B are respectively perspective and cross-section views of a drainage block according to an alternative embodiment
- - FIGS. 6 and 7 are perspective views of two other alternative embodiments of the drainage block according to the invention.
- the modular drainage block 1 is intended to drain the soil, for example but not exclusively, around a house or a building. It comprises an elongated body 2, a longitudinal collecting duct 3 passing through the body right through and runoff passages 5 opening onto the peripheral walls of the body 2 and opening into the collecting duct 3 arranged to allow the circulation of water from gravity runoff towards said conduit. It also includes connecting means 6 arranged to assemble two consecutive drainage blocks 1 and a water-permeable outer casing 7 only visible in dotted lines in FIG. 1.
- the elongated body 2 must be able to withstand the pressure of a soil charge. To this end, it preferably has a polygonal, or possibly semicircular, section. Its shape defines at least one flat base 20 and a flat side wall 21 forming with said base a right angle making it possible to position the modular drainage block 1 at the base and along the foundations 9 of a building.
- This body 2 can be made of a waterproof material such as polystyrene, polyvinyl chloride, concrete, synthetic resin or any other equivalent synthetic or non-synthetic material, molded or extruded. It can also be produced in a material permeable to water such as for example more or less dense expanded polystyrene or any other synthetic material foamed or structured for example in honeycomb. The main thing is that the combination of the geometry of this body and its material or structure allows it to offer sufficient resistance to compression to withstand an earth load.
- a waterproof material such as polystyrene, polyvinyl chloride, concrete, synthetic resin or any other equivalent synthetic or non-synthetic material, molded or extruded. It can also be produced in a material permeable to water such as for example more or less dense expanded polystyrene or any other synthetic material foamed or structured for example in honeycomb.
- honeycomb honeycomb
- a sealed zone can be provided below the collecting duct 3 to prevent the flow of drainage water into the ground.
- This waterproof zone can consist of a sole (not shown) made of an impermeable material incorporated in or under the body 2.
- the longitudinal collecting duct 3 is preferably arranged in the lower part of the body 2 in order to be able to collect the drainage water by gravity. It is straight and substantially parallel to the base 20 of said body. It has a circular section but could have a section of different shape. It may, depending on the needs and the nature of the material constituting said body 2, include a sealed inner envelope (not shown) attached or integrated using a method of overmolding for example. This collecting duct 3 also has ends 30 of larger diameter, arranged to receive the connection means 6 described below.
- the runoff passages 5 are constituted, in this example, by peripheral grooves 50 opening into the collecting duct 3 by transverse channels 51 provided on either side of said duct.
- the peripheral grooves 50 are substantially identical and have a U-shaped profile, but could have a profile of different shape, of greater or lesser depth. They are formed in the upper 22 and side 21 walls of the body 2. They are rectilinear and arranged at regular intervals along the drainage block 1.
- the section of the drainage block 1 illustrated in FIG. 3 shows that each groove 50 defines , in the middle part and near the upper wall 22, a top of which extends on either side an inclined plane to facilitate the circulation of drainage water by gravity.
- the transverse channels 51 are oriented substantially perpendicular to the collecting duct 3 and arranged so as to open into this collecting duct 3 tangentially to its bottom. They are identical and have a circular section but could have a section of different shape. They can be slightly inclined in the direction of said collecting duct 3 to promote the circulation of drainage water by gravity.
- each transverse channel 51 is connected to three peripheral grooves 50. The section of each transverse channel 51 is greater than that of the peripheral grooves 50, just as the section of the collecting duct 3 is significantly greater than that of the channels transverse 51, to be able to respond to the flow of drainage water.
- connection means 6 comprise, in the example illustrated by FIG. 4, a sleeve 60 distinct from the body 2, cylindrical and having an outside diameter at most equal to the inside diameter of the ends 30 of the collecting duct 3.
- This sleeve 60 is intended to fit into the ends 30 opposite the collecting ducts 3 of two consecutive drainage blocks 1 making it possible to assemble them linearly.
- connection means 6 also include a lateral opening 61 provided in each side wall 21 of the body 2 at the same level as the collecting duct 3, near one of its ends and opening into this duct.
- These lateral openings are circular but could have a different shape and have a diameter substantially equal to that of the ends 30 of said conduit. They are arranged to receive the sleeve 60 allowing two consecutive drainage blocks 1 to be assembled at right angles, as shown in FIG. 4.
- These lateral openings 61 are delimited by a precut area 62 formed in the lateral walls 21 of said body 2. To use them, it is necessary to remove the precut area 62 which then forms a plug serving to close off the end 30 of the corresponding collecting duct 3.
- the outer envelope 7 consists of a fabric made of a geotextile material, of substantially rectangular shape, intended to be wound around the body 2 and if necessary stapled to the body.
- the longitudinal dimensions of this fabric 7 are greater than those of the drainage block 1 so as to at least partially cover the following drainage block 1. Thus the assembly area between two consecutive drainage blocks 1 is also covered.
- This fabric 7 makes it possible to retain the particles of soil, stones and any other material capable of clogging the runoff passages 5 of the drainage block 1 and therefore rendering the latter ineffective.
- other equivalent means could also be suitable, such as for example a very fine mesh envelope, glued, overmolded or attached around said body 2.
- Drainage blocks 1 made for example of polystyrene expanded, have the advantage of being inexpensive, very light, easy to handle and work, and being able to land in all weathers even at very low temperatures. In addition, they are non-polluting, rot-proof and do not retain moisture.
- FIG. 1 makes it possible to compare very clearly the traditional drainage method, on the left, with that carried out with the drainage block 1 according to the invention, on the right.
- a trench 90 is dug around the foundations 9 of a building.
- we cover the trench with a geotextile fabric we deposit the perforated collecting pipe, on which we pour gravel which we then cover with the two sections of geotextile fabric, then we backfill.
- the drainage blocks 1 are positioned directly in the bottom of the trench 90 arranged in a slight slope, they are assembled one after the other by the sleeves 60 and then backfilled . It is easy to see that the realization of a drainage is greatly simplified by the fact that the drainage block 1 integrates in a single module at the same time the collecting conduit, the runoff passages and the geotextile filter.
- This drainage system once in place, has the advantage of ensuring efficient and lasting drainage over time, the drainage blocks 1 being dimensionally very stable, despite possible landslides.
- the drainage water is filtered by the geotextile casing 7 and is channeled by the peripheral grooves 50 in which they flow by gravity to the transverse channels 51, which centralize them in the collecting duct 3, the latter discharging them into the sanitation network.
- the runoff passages 5 may consist of a multitude of transverse channels 52, straight and of small section, extending directly from the peripheral walls of the body 2 of the drainage block 1 to the conduit manifold 3.
- the connection means 6 consist of a sleeve 63 forming a single piece with the body 2, arranged in extension of one of the ends of the manifold conduit 3 and arranged to form a male part.
- the other end 64 of the collecting duct 3 is arranged to form a female part intended to receive the male part 63 of an adjacent drainage block 1.
- the runoff passages 5 may also consist of peripheral baffles 53 opening into the collecting duct 3 by transverse channels 51.
- peripheral baffles 53 may be formed by relief shapes provided at the periphery of the body 2, such as for example round studs 54 (see fig. 6) or parallelepipedic studs 55 (see fig. 7) or any other form of different geometry.
- Yet another solution consists in making the body 2 according to a porous structure, the runoff passages 5 being formed by the interstices of this porous structure.
