Abstract
Description
La présente invention a pour objet un dispositif de drainage. The present invention relates to a drainage device.
Pour faciliter l'écoulement des eaux dans les terrains trop humides, on a depuis longtemps proposé des dispositifs de drainage de différents types notamment des fagots de branches de chataignier
Parmi ces dispositifs, on peut citer ceux qui consistent à implanter dans le sol, des tubes en terre cuite poreuse, que l'on place les uns à la suite des autres, de façon à diriger l'écoulement des eaux.To facilitate the flow of water in excessively wet terrain, drainage devices of various types have been proposed for a long time, in particular bundles of chestnut branches.
Among these devices, there may be mentioned those which consist in implanting in the ground, porous terracotta tubes, which are placed one after the other, so as to direct the flow of water.
De tels tubes sont très couramment utilisés, mais, ne sont pas sans avoir de nombreux inconvénients, étant donné fusils sont d'un prix de revient élevé, et que, leur pose est relativement difficile, et donc coûteuse
Pour améliorer ces tubes, on a proposé de les rempli cer par des tubes en plastique cannelés, comportant des fentes et dont le diamètre peut aller de 50 m/m å 125 m/m et plus
Mais, oes tubes en plastique ne sont pas susceptibles, eux-non plus, d'apporter une solution idéale, au problème posé par lsécoulement des eaux dans les terrains trop humides, étant donne qugils risquent de se boucher, et donc ce colmatage le:: empêche dans le temps de remplir totalement leur r81e,
Ces tubes en plastique supportent mal le passage d'engins et s'écrasent, ce qui n'est pas le cas des boudins de fibres qui ne se détériorent pas au passage engins routiers ou agricoles.Such tubes are very commonly used, but, are not without having many drawbacks, since rifles are of a high cost price, and that, their installation is relatively difficult, and therefore expensive.
To improve these tubes, it has been proposed to fill them with fluted plastic tubes, having slits, the diameter of which can range from 50 m / m to 125 m / m and more.
But, these plastic tubes are not likely, either, to provide an ideal solution to the problem posed by the flow of water in excessively wet ground, given that they risk becoming blocked, and therefore this clogging: : prevents over time from fully fulfilling their role,
These plastic tubes poorly support the passage of machines and are crushed, which is not the case of the strands of fibers which do not deteriorate in the passage of road or agricultural vehicles.
Pour remédier à ce risque de bouchage, il est connu d'introduire de la caillasse autour des orifices de ces tubes, mai on se heurte là encore, à des problèmes liés au prix de revient extrêmement élevé de la pose de ces tubes. To remedy this risk of blockage, it is known to introduce the pebble around the orifices of these tubes, but again, there are problems associated with the extremely high cost price of laying these tubes.
La présente invention a pour Objet de remédier à ces inconvénients, en proposant un dispositif de drainage donnant toute satisfaction et ne risquant pas de s'obturer, ni d'être écrasé par les passages d'engins tout en étant d'un prix de revien peu élevé, tant en ce qui concerne sa pose que sa fabrication. The object of the present invention is to remedy these drawbacks by proposing a drainage device which gives all satisfaction and which is not likely to become blocked, or to be crushed by the passage of machines while being cost effective. low, both in terms of its installation and its manufacture.
A cet effet, l'invention concerne un dispositif de drainage caractérisé en ce qu'il est constitué par un boudin rempli de fibres de bois imputrescibles. To this end, the invention relates to a drainage device characterized in that it is constituted by a rod filled with rot-proof wood fibers.
Ainsi, l'invention propose un dispositif qui ne ris que en aucune manière de se boucher, et dont le prix de revient es particulièrement peu élevé. Thus, the invention proposes a device which risks in no way being blocked, and whose cost is particularly low.
Selon une autre caractéristique de l'invention, les fibres de bois sont des fibres notamment de châtaignier, fibres qui sont particulièrement imputrescibles en milieu humide. According to another characteristic of the invention, the wood fibers are fibers, in particular of chestnut, fibers which are particularly rot-proof in a humid environment.
Selon une autre caractéristique de l'invention, les fibres de châtaignier sont disposées dans un filet et de préférence dans un filet en une matière synthétique ou végétale ; ce qui là encore, assure un abaissement du prix de revient du dispositif tout en facilitant sa mise en place. According to another characteristic of the invention, the chestnut fibers are arranged in a net and preferably in a net made of a synthetic or vegetable material; which again ensures a lowering of the cost price of the device while facilitating its installation.
Dans le cas d'un filet en matière plastique, on utilise une matière ne pouvant s'allonger ni en largeur ni en longueur. In the case of a plastic net, a material is used which cannot be extended either in width or in length.
Bien entendu, de tels boudins peuvent être de dimensions quelconques, dépendant des caractéristiques du sol à assécher et en particulier, on peut prévoir des boudins ayant un diamètre approximativement égal à dix centimètres et plus. Of course, such strands can be of any size, depending on the characteristics of the soil to be dried and in particular, one can provide strands having a diameter approximately equal to ten centimeters and more.
Les caractéristiques du dispositif de drainage qui fait l'objet de l'invention seront décrites plus en détail à l'aide du dessin annexé, qui le représente de manière schématique. The characteristics of the drainage device which is the subject of the invention will be described in more detail with the aid of the appended drawing, which shows it schematically.
Selon cette figure, le dispositif qui fait l'objet de l'invention se compose d'un boudin 1 constitué par des fibres de bois imputrescibles 2e par exemple de fibres de châtaignier, ou des fibres synthétiques imputrescribles. According to this figure, the device which is the subject of the invention consists of a flange 1 constituted by rot-proof wooden fibers 2e, for example chestnut fibers, or rot-proof synthetic fibers.
Ces fibres de châtaignier 2 2 sont disposées dans un filet 3 en matériau synthétique. These chestnut fibers 2 2 are arranged in a net 3 made of synthetic material.
D'une façon préférentielle, le diamètre 0 du boudin est approximativement égal à dix centimètres, et est bien entendu, variable en fonction des caractéristiques du sol à drainer. Preferably, the diameter 0 of the rod is approximately equal to ten centimeters, and is of course, variable depending on the characteristics of the soil to be drained.
Ainsi, l'invention permet la mise au point d'un dispositif de drainage simple, bon marché et d'un emploi facile. Thus, the invention allows the development of a simple drainage device, inexpensive and easy to use.
