TUYAU D'EPANDAGE A DEBIT REGLABLEADJUSTABLE FLOW SPREADING HOSE

DESCRIPTIONDESCRIPTION

Domaine de l'invention L'invention concerne le domaine des dispositifs d'épandage d'eau dans le sol, comme c'est le cas pour les eaux usées dans les installations  Field of the Invention The invention relates to the field of devices for spreading water in the ground, as is the case for waste water in installations.

d'assainissement.sanitation.

Art antérieur et problème posé Il est connu de stocker temporairement les eaux usées ou autres liquides domestiques dans des récipients, réserves ou citernes, dans le but de les expédier vers un réseau d'épandage. Il est très fréquent d'utiliser alors des chasses d'eau qui envoient une quantité déterminée d'eau stockée vers le réseau d'épandage constitué d'un ou plusieurs tuyaux répartis dans ou sur le sol. C'est, entre autres, le cas des fosses septiques o l'eau a été débarrassée de  PRIOR ART AND PROBLEM POSED It is known to temporarily store used water or other domestic liquids in receptacles, reserves or cisterns, in order to send them to a spreading network. It is very common to use flushes that send a determined quantity of stored water to the spreading network consisting of one or more pipes distributed in or on the ground. This is, among other things, the case of septic tanks where the water has been rid of

ses matières en suspension dans la cuve de la fosse.  its suspended matter in the tank of the pit.

Elle est ensuite chassée de cette cuve et distribuée vers un système d'épandage constitué généralement de  It is then expelled from this tank and distributed to a spreading system generally consisting of

tuyaux percés.drilled pipes.

Or, quelle que soit la forme du réseau de tuyaux, cet épandage s'effectue dans les premiers mètres de canalisations. En effet, comme le montre la figure 1, une première réalisation d'un tuyau d'épandage usuel est constituée principalement de tuyaux, tels que la portion de tuyau 1, équipée d'un grand nombre de fentes 2, placé dans la partie inférieure du diamètre du tuyau 1, de manière à ce que l'eau s'écoule petit à petit par ses fentes. Or, les fentes 2 ont une largeur de 5 mm. Lorsque de l'eau est envoyée dans le tuyau 1, au moyen d'une chasse d'eau, une grande partie de l'eau s'écoule par les premières fentes 2 dans le premier mètre. La répartition d'eau  However, whatever the shape of the network of pipes, this spreading takes place in the first meters of pipes. Indeed, as shown in Figure 1, a first embodiment of a conventional spreading pipe consists mainly of pipes, such as the pipe portion 1, equipped with a large number of slots 2, placed in the lower part of the diameter of the pipe 1, so that the water flows little by little through its slots. However, the slots 2 have a width of 5 mm. When water is sent into the pipe 1, by means of a flush, a large part of the water flows through the first slots 2 in the first meter. Water distribution

sur une grande longueur n'est alors pas obtenue.  over a long length is then not obtained.

En référence à la figure 2, une amélioration consiste à ménager une garde d'eau 10 dans un tuyau 11 percé d'orifices latéraux 12 dont la partie inférieure se trouve au niveau de la garde d'eau 10 dans le tuyau 11. Une telle garde d'eau 10 peut avoir une hauteur de 10 à 15 mm, tandis que le diamètre du tuyau 11 est de l'ordre de 10 cm. Avec ce système, l'eau se répartie nettement mieux sur la longueur du tuyau 11. Toutefois, la mise en place de celui-ci est très laborieuse car elle consiste, entre autres, à aligner tous les trous  With reference to FIG. 2, an improvement consists in providing a water guard 10 in a pipe 11 pierced with lateral orifices 12, the lower part of which is located at the level of the water guard 10 in the pipe 11. Such a guard 10 can have a height of 10 to 15 mm, while the diameter of the pipe 11 is of the order of 10 cm. With this system, the water is distributed much better over the length of the pipe 11. However, the installation of the latter is very laborious because it consists, among other things, in aligning all the holes

12 et le terrain, car le tuyau 11 doit être horizontal.  12 and the ground, because the pipe 11 must be horizontal.

Cette mise au point est difficile et longue.  This development is difficult and long.

Le but de l'invention est de remédier à cet inconvénient, en proposant un autre concept de tuyau d'épandage dont la mise en place est aisée et la  The object of the invention is to remedy this drawback by proposing another concept of spreading pipe, the installation of which is easy and the

fabrication non compliquée.uncomplicated manufacturing.

Résumé de l'invention L'objet principal de l'invention est donc un tuyau d'épandage comprenant une pluralité de trous  Summary of the invention The main object of the invention is therefore a spreading pipe comprising a plurality of holes

répartis sur la longueur de l'épandage.  distributed over the length of the spreading.

Selon l'invention, une bague est montée tournante et ajustée autour du tuyau d'épandage, au niveau du trou correspondant et possédant elle-même un trou de bague. De la sorte, il est possible, par rotation angulaire de la bague autour du tuyau d'épandage, de positionner plus ou moins le trou de bague en regard du trou du tuyau pour boucher et ouvrir  According to the invention, a ring is rotatably mounted and adjusted around the spreading pipe, at the level of the corresponding hole and itself having a ring hole. In this way, it is possible, by angular rotation of the ring around the spreading pipe, to position the ring hole more or less opposite the pipe hole for plugging and opening

plus ou moins le trou du tuyau, et en régler le débit.  more or less the hole of the pipe, and regulate the flow.

De préférence, les trous du tuyau et de la bague sont ronds et sont placés à la même position angulaire. Par contre, il est plus pratique que les trous de bague soient plus petits que ceux du tuyau d'épandage. Avantageusement, les bagues peuvent être constituées chacune d'un petit tronçon du tuyau  Preferably, the holes in the pipe and the ring are round and are placed at the same angular position. On the other hand, it is more practical for the ring holes to be smaller than those of the spreading pipe. Advantageously, the rings can each consist of a small section of the pipe

Description détaillée de l'invention  Detailed description of the invention

En référence à la figure 3, le tuyau d'épandage selon l'invention comprend, bien entendu, un tuyau 21 qui est également muni de trous latéraux 22. Ces derniers sont placés à la même position angulaire sur le tuyau d'épandage 21. En d'autres termes, ils sont alignés. Le tuyau d'épandage 21 est placé sur le sol, de manière à ce qu'un débit d'eau, même infime, à l'intérieur du tuyau d'épandage 21 puisse au moins affleurer la base de chaque trou 22, lorsque le tuyau  With reference to FIG. 3, the spreading pipe according to the invention comprises, of course, a pipe 21 which is also provided with lateral holes 22. These are placed at the same angular position on the spreading pipe 21. In other words, they are aligned. The spreading pipe 21 is placed on the ground, so that even a small flow of water inside the spreading pipe 21 can at least be flush with the base of each hole 22, when the pipe

d'épandage 21 est horizontal.21 is horizontal.

L'invention consiste principalement à utiliser, pour chaque trou 22 du tuyau d'épandage 21, une bague 30. Cette dernière a un diamètre interne correspondant au diamètre externe du tuyau d'épandage 21, une longueur suffisante pour couvrir largement un trou 22 du tuyau d'épandage 21. De plus, chaque bague possède un trou de bague 31, d'un diamètre légèrement plus petit que celui des trous 22 du tuyau d'épandage 21. Les trous 22 et 31 sont ronds, de  The invention mainly consists in using, for each hole 22 of the spreading pipe 21, a ring 30. The latter has an internal diameter corresponding to the external diameter of the spreading pipe 21, a length sufficient to largely cover a hole 22 in the spreading pipe 21. In addition, each ring has a ring hole 31, of a diameter slightly smaller than that of the holes 22 of the spreading pipe 21. The holes 22 and 31 are round, of

manière à permettre un réglage fin du débit de l'eau.  so as to allow fine adjustment of the water flow.

En effet, chaque bague 30 peut tourner autour du tuyau d'épandage 21, de manière à placer chaque trou de bague 31 plus ou moins en regard d'un des trous 22 des tuyaux d'épandage 21. De la sorte, chaque débit des trous 22 peut être réglé par rotation de la bague 30 qui lui est associée. Ainsi, il est possible, sur un tuyau d'épandage de plusieurs mètres, avec des trous de diamètre de 20 mm, de répartir un débit sur tous ces trous par un filet d'eau très réduit au niveau de chaque trou 22 du tuyau d'épandage 21. Ainsi, 10 1 d'eau peuvent être répartis uniformément, pendant 1 h. On note que les bagues 30 peuvent être réalisées au moyen d'un simple tronçon relativement  In fact, each ring 30 can rotate around the spreading pipe 21, so as to place each ring hole 31 more or less opposite one of the holes 22 in the spreading pipes 21. In this way, each flow of holes 22 can be adjusted by rotation of the ring 30 associated therewith. Thus, it is possible, on a spreading pipe of several meters, with holes of diameter 20 mm, to distribute a flow over all these holes by a very reduced trickle of water at each hole 22 of the pipe d 'spreading 21. Thus, 10 1 of water can be distributed uniformly, for 1 h. It should be noted that the rings 30 can be produced by means of a simple relatively long section.

court de tuyau, fendu, puis troué.short of pipe, split, then pierced.

On comprend que, selon la position du tuyau d'épandage 21, qui est en général flexible, il est possible de régler le débit de chaque trou 22. Ainsi, lorsque le terrain sur lequel le tuyau d'épandage 21 est placé, n'est pas régulier, le débit de chaque trou 22 peut être réglé à la carte. De plus, ce débit est réglable quantitativement en utilisant toutes les positions angulaires de la bague 30 autour du tuyau d'épandage 21. Il est donc possible de régler chaque  It is understood that, depending on the position of the spreading pipe 21, which is generally flexible, it is possible to adjust the flow rate of each hole 22. Thus, when the ground on which the spreading pipe 21 is placed, does not is not regular, the flow rate of each hole 22 can be adjusted à la carte. In addition, this flow rate is quantitatively adjustable by using all the angular positions of the ring 30 around the spreading pipe 21. It is therefore possible to adjust each

trou par un débit du type goutte à goutte.  hole by a drip type flow.

Avantages de l'invention Lorsque le tuyau est horizontal, ce système  Advantages of the invention When the pipe is horizontal, this system

ne nécessite pas de rajouter une pompe artificielle.  no need to add an artificial pump.

L'efficacité du traitement de l'eau par le  The effectiveness of water treatment by the

sol ou le sable est multipliée par trois ou par quatre.  soil or sand is multiplied by three or four.

Il est également possible de concevoir un matériel industriel de traitement de l'eau en utilisant  It is also possible to design industrial water treatment equipment using

un tel tuyau d'épandage.such a spreading hose.

Compte tenu du fait que la réglementation en matière d'assainissement oblige d'utiliser une grande surface d'épandage, le tuyau d'épandage selon l'invention permet de réduire ces surfaces nécessaires  Given the fact that the sanitation regulations require the use of a large spreading area, the spreading pipe according to the invention makes it possible to reduce these necessary areas

avec des systèmes de l'art antérieur.  with prior art systems.

Enfin, du fait que tuyau d'épandage selon l'invention permet d'améliorer la rentabilité parmi ces surfaces des systèmes d'épandage, elle peut contribuer à réduire les rejets en rivières et les canalisations pour effectuer de tels rejets. L'invention s'applique particulièrement aux installations d'assainissement individuelles et collectives. -7  Finally, since the spreading hose according to the invention improves the profitability among these surfaces of the spreading systems, it can contribute to reducing the discharges into rivers and the pipes for carrying out such discharges. The invention is particularly applicable to individual and collective sanitation installations. -7
