Description

La présente invention concerne le domaine de la protection des immeubles, habitations et constructions analogues contre les dommages liés à la présence d'eau ou d'humidité dans les murs, ouvrages de maçonnerie ou analogues.The present invention relates to the field of protection of buildings, houses and similar constructions against damage related to the presence of water or moisture in walls, masonry or similar.

L'invention vise plus particulièrement à combattre les remontées d'eau dans le contexte précité et a pour objets un dispositif électronique et un procédé pour stopper les remontées d'eau et d'humidité par capillarité.The invention is aimed more particularly at combating upwellings in the aforementioned context and has for its objects an electronic device and a method for stopping the upwelling and humidity by capillarity.

Dans une construction, les dommages ou désordres dus à l'humidité peuvent avoir diverses origines : infiltrations en façade, infiltrations dans le soubassement enterré, problèmes de condensation dus à une mauvaise isolation (ou à la surisolation) ou à une absence due ventilation suffisante, ou encore, dans les cas les plus fréquents, à un problème de remontées capillaires.In a construction, the damage or disorders due to the humidity can have various origins: infiltrations in frontage, infiltrations in the buried basement, problems of condensation due to bad insulation (or over-insulation) or to a lack due to sufficient ventilation, or, in the most frequent cases, to a problem of capillary rise.

Dans ce dernier cas, on constate qu'il y a à l'origine du phénomène des remontées capillaires, ce que l'on appelle la poussée électro-osmotique engendrée ou favorisée par des phénomènes telluriques liés à la présence de champs électromagnétiques naturels. On peut en mesurer l'existence et les effets, mais à ce jour, une modélisation n'a pas encore pu. être effectuée en raisons d'une méconnaissance des lois relatives aux sciences de la terre et des phénomènes physico-chimiques impliqués.In the latter case, we find that there is at the origin of the phenomenon of capillary rise, what is called the electro-osmotic thrust generated or favored by telluric phenomena related to the presence of natural electromagnetic fields. We can measure the existence and effects, but to date, modeling has not yet been able. be carried out because of a lack of knowledge of the laws relating to earth sciences and physico-chemical phenomena involved.

En présence de telles remontées, on constate que les structures inférieures des murs sont chargées positivement à leur base et négativement en hauteur. Ces deux zones aux charges électriques opposées donnent naissance à un champ électrique orienté du bas vers le haut du mur, entraînant ainsi les molécules d'eau, de même que les ions sels, dans les capillaires vers le haut du mur.In the presence of such lifts, it is found that the lower structures of the walls are positively charged at their base and negatively in height. These two zones with opposite electrical charges give rise to an electric field directed from the bottom to the top of the wall, thus causing the water molecules, as well as the salt ions, in the capillaries towards the top of the wall.

Les molécules d'eau dans les capillaires, de par leur constante diélectrique élevée et leur caractère bipolaire (dipôle) sont très sensibles aux phénomènes tellurique, mêmes faibles, mais dont l'énergie est néanmoins suffisante pour exercer la poussée capillaire. A cette force s'ajoutent les effets du potentiel Zéta produit par le frottement de l'eau dans les capillaires, ce qui accroît encore la poussée capillaire.The water molecules in the capillaries, by their high dielectric constant and their bipolar character (dipole) are very sensitive to telluric phenomena, even weak, but whose energy is nevertheless sufficient to exert the capillary thrust. To this force are added the effects of the Zeta potential produced by the friction of the water in the capillaries, which further increases the capillary thrust.

Les effets destructeurs des remontées capillaires sont variables et fonction de la nature et de la structure capillaire des matériaux en présence, ainsi que de la nature et de la quantité des sels dissous dans les capillaires.The destructive effects of capillary rise are variable and depend on the nature and the capillary structure of the materials in the presence, as well as the nature and the amount of salts dissolved in the capillaries.

Actuellement, la plupart des procédés existants utilisés pour combattre les remontées capillaires sont destructifs. Ils nécessitent des travaux lourds et coûteux avec, par exemple, dans certains cas l'utilisation de produits chimiques néfastes pour l'environnement, dans d'autres cas la pose d'électrodes consommant dans certains cas des quantités d'énergie importantes, ou encore le tronçonnage des murs avec insertion d'une plaque en acier inoxydable.Currently, most of the existing methods used to combat hairline lift are destructive. They require heavy and expensive work with, for example, in some cases the use of chemicals harmful to the environment, in other cases the laying of electrodes consuming in some cases large amounts of energy, or cutting the walls with insertion of a stainless steel plate.

On connaît également des dispositifs électroniques passifs parfaitement écologiques et basés sur l'interférence.Passive electronic devices that are perfectly ecological and based on interference are also known.

Malheureusement tous ces procédés connus demandent souvent des délais d'assèchement longs, ce qui peut être incompatible avec les délais courts imposés actuellement lors de réfections ou de réhabilitations de bâtiments anciens.Unfortunately all these known processes often require long periods of drying, which may be incompatible with the short time currently imposed during repairs or rehabilitations of old buildings.

Enfin, on connaît également des dispositifs électroniques basés sur la création de champs électromagnétiques et comprenant généralement des moyens de génération d'un signal à fréquence fixe (généralement 141 kHz) alimentant au moins un résonateur ou élément rayonnant analogue situé dans le voisinage de la partie au moins de mur ou de maçonnerie à traiter.Finally, there are also known electronic devices based on the creation of electromagnetic fields and generally comprising means for generating a fixed frequency signal (generally 141 kHz) supplying at least one resonator or similar radiating element located in the vicinity of the part at least wall or masonry to be treated.

Toutefois, ces dispositifs électroniques connus, par exemple par les documents EP-A-0836639 , AT-392 109 , EP-0 395 085 , EP-0 928 856 ou WO 94/20702 , présentent tous des constitutions complexes et/ou trop fragiles, c'est-à-dire ne présentant pas une fiabilité de fonctionnement dans le temps indispensable pour ce type de dispositifs, et/ou ne présentent pas une efficacité suffisante pour obtenir des résultats relativement rapides et qui perdurent.However, these known electronic devices, for example by the documents EP-A-0836639 , AT-392 109 , EP-0 395 085 , EP-0 928 856 or WO 94/20702 , all have complex constitutions and / or too fragile, that is to say not having a reliability of operation over time essential for this type of devices, and / or do not have sufficient efficiency to achieve results relatively fast and lasting.

La présente invention a pour but de pallier les inconvénients et de surmonter les limitations des différentes solutions connues mentionnées ci-dessus et de proposer un dispositif et un procédé pour stopper les remontées d'eau et d'humidité par capillarité qui soient simple, efficace et fiable, et ne mettent en oeuvre que des quantités d'énergie faibles et des rayonnements inoffensifs.The object of the present invention is to overcome the drawbacks and to overcome the limitations of the various known solutions mentioned above and to propose a device and a method for stopping the capillary rise of water and moisture that are simple, effective and efficient. reliable, and implement only low energy quantities and harmless radiation.

Pour aboutir au but recherché, la présente invention a pour premier objet un dispositif électronique pour stopper les remontées d'eau et d'humidité par capillarité dans les murs, ouvrages de maçonnerie ou analogues, comprenant des moyens de génération d'un signal modulé alimentant au moins un résonateur situé au voisinage d'une partie au moins de mur ou de maçonnerie à traiter, caractérisé en ce que le signal modulé alimentant ledit au moins un résonateur comprend une porteuse dont la fréquence est comprise entre 25 et 65 kHz ou entre 143 et 150 kHz et qui est modulée par un signal modulant dont la fréquence est comprise entre 45 et 49 Hz, ledit ou lesdits résonateurs émettant chacun un champ électrique fonction du signal modulé précité et apte à modifier les caractéristiques électriques des molécules d'eau présentes dans la partie de mur ou de maçonnerie affectée par ledit champ, ainsi que celles des surfaces des capillaires de ladite partie en contact avec ces molécules d'eau.To achieve the goal, the present invention firstly relates to an electronic device for stopping the rise of water and moisture by capillarity in walls, masonry or the like, comprising means for generating a modulated signal supplying at least one resonator located in the vicinity of at least a portion of wall or masonry to be treated, characterized in that the modulated signal supplying said at least one resonator comprises a carrier whose frequency is between 25 and 65 kHz or between 143 and 150 kHz and which is modulated by a modulating signal whose frequency is between 45 and 49 Hz, said one or more resonators each emitting an electric field function of the aforementioned modulated signal and able to modify the electrical characteristics of the water molecules present in the part of wall or masonry affected by the said field, as well as those of the capillary surfaces of the said part in contact with each other. t with these water molecules.

L'invention a également pour objet un procédé pour stopper les remontées d'eau et d'humidité par capillarité dans les murs, ouvrages de maçonnerie ou analogues, caractérisé en ce qu'il consiste à soumettre, de manière séquentielle ou continue, une partie au moins d'un mur ou d'un ouvrage de maçonnerie à traiter à un champ électrique émis par au moins un résonateur alimenté par des moyens de génération d'un signal modulé formé par une porteuse dont la fréquence est comprise entre 25 et 65 kHz ou entre 143 et 150 kHz et qui est modulée par un signal modulant dont la fréquence est comprise entre 45 et 49 Hz, le ou les champ(s) électrique(s) émis étant apte(s) à modifier les caractéristiques électriques des molécules d'eau présentes dans la partie de mur ou de maçonnerie affectée par ledit champ, ainsi que celles des surfaces capillaires de ladite partie en contact avec ces molécules d'eau.The invention also relates to a method for stopping the upwelling and humidity by capillarity in walls, masonry or the like, characterized in that it consists in subjecting, sequentially or continuously, a part of at least one wall or masonry structure to be treated at an electric field emitted by at least one resonator fed by means for generating a modulated signal formed by a carrier whose frequency is between 25 and 65 kHz or between 143 and 150 kHz and which is modulated by a modulating signal whose frequency is between 45 and 49 Hz, the electric field (s) emitted being able to modify the electrical characteristics of the d molecules. water present in the part of wall or masonry affected by said field, as well as those of the capillary surfaces of said part in contact with these water molecules.

Le principe de base de la présente invention consiste par conséquent à soumettre la partie de mur ou de maçonnerie à traiter à un champ électrique de faible puissance (typiquement de quelques milliwatts, par exemple entre 0,5 et 20 milliwatts) généré par un signal présentant une composition fréquentielle comme indiqué précédemment.The basic principle of the present invention therefore consists in subjecting the portion of wall or masonry to be treated to a low power electric field (typically a few milliwatts, for example between 0.5 and 20 milliwatts) generated by a signal having a frequency composition as indicated above.

En effet, l'inventeur a constaté, de manière inattendue et surprenante, qu'en soumettant la partie de mur ou de maçonnerie analogue à un tel champ, on obtenait des résultats rapides et durables dans le temps en termes de suppression des remontées capillaires d'eau et d'humidité.Indeed, the inventor has found, unexpectedly and surprisingly, that by subjecting the part of wall or masonry similar to such a field, one obtained fast and durable results over time in terms of suppression of capillary rise of water and humidity.

Il convient de noter que ce principe à la base de l'invention n'a rien de commun avec les systèmes à inversion de polarité des murs utilisés en électro-osmose-phorèse qui nécessitent des puissances bien plus importantes pour modifier le sens de migration des molécules d'eau.It should be noted that this principle underlying the invention has nothing in common with the reverse polarity systems of the walls used in electroosmosis-phoresis which require much higher powers to modify the direction of migration of the water molecules.

En effet, l'invention ne vise pas à inverser la polarité des murs à distance pour combattre la "poussée électro-osmotique",ce qui demanderait une énergie importante, mais de modifier par l'émission d'un champ électrique, l'orientation des molécules d'eau, ainsi que la nature de la charge électrique desdites molécules d'eau et des capillaires des murs en contact avec ces dernières, ainsi que la tension superficielle de l'eau de manière à supprimer l'effet d'attraction de l'eau vers le haut du mur.Indeed, the invention is not intended to reverse the polarity of the walls at a distance to combat the "electro-osmotic thrust", which would require significant energy, but to change by the emission of an electric field, the orientation water molecules, as well as the nature of the electric charge of said water molecules and the capillaries of the walls in contact therewith, as well as the surface tension of the water so as to suppress the attraction effect of water up the wall.

Conformément à l'invention, le signal modulé SM alimentant ledit au moins un résonateur 6 comprend une porteuse dont la fréquence est comprise entre 25 et 65 kHz ou entre 143 et 150 kHz et qui est modulée par un signal modulant SI dont la fréquence est comprise entre 45 et 49 Hz, ledit ou lesdits résonateurs 6 émettant chacun un champ électrique fonction du signal modulé SM précité et apte à modifier les caractéristiques électriques des molécules d'eau présentes dans la partie de mur ou de maçonnerie 2' affectée par ledit champ, ainsi que celles des surfaces des capillaires de ladite partie 2' en contact avec ces molécules d'eau.According to the invention, the modulated signal SM supplying said at least one resonator 6 comprises a carrier whose frequency is between 25 and 65 kHz or between 143 and 150 kHz and which is modulated by a modulating signal SI whose frequency is included between 45 and 49 Hz, said one or more resonators 6, each emitting an electric field according to the abovementioned modulated signal SM and able to modify the electrical characteristics of the water molecules present in the part of wall or masonry 2 'affected by said field, as well as those of the capillary surfaces of said portion 2 'in contact with these water molecules.

Selon un mode de réalisation avantageux, présentant une efficacité accrue, la fréquence de la porteuse est variable et le signal modulant SI consiste en un signal impulsionnel ayant une fréquence d'environ 47 Hz, préférentiellement constitué d'impulsions de forme carrée.According to an advantageous embodiment, having an increased efficiency, the frequency of the carrier is variable and the modulating signal SI consists of a pulse signal having a frequency of about 47 Hz, preferably consisting of square-shaped pulses.

Selon une variante préférée du mode de réalisation précité, les moyens 3, 4, 5 de génération de signal modulé SM génèrent un signal modulé dont la porteuse présente une fréquence alternativement comprise dans la plage 25 à 65 kHz et dans la plage 143 à 150 kHz, ladite fréquence étant en outre préférentiellement variable dans ces deux plages.According to a preferred variant of the aforementioned embodiment, the means 3, 4, 5 of modulated signal generation SM generate a modulated signal whose carrier has a frequency alternately in the range 25 to 65 kHz and in the range 143 to 150 kHz , said frequency being moreover preferably variable in these two ranges.

Chaque résonateur 6 peut, par exemple, être constitué par un ou deux circuit(s) oscillant(s) LC parallèle(s), le cas échéant, à inductances opposées, préférentiellement sous la forme de circuit(s) imprimé(s) ou bobinées en fils de cuivre émaillé, le cas échéant disposés parallèlement entre eux.Each resonator 6 may, for example, be constituted by one or two oscillating circuit (s) LC parallel (s), where appropriate, with opposite inductances, preferably in the form of circuit (s) printed (s) or wound in enamelled copper wire, if necessary arranged parallel to each other.

Les inductances opposées sont reliées mutuellement deux à deux à l'une de leurs extrémités dans chaque résonateur 6 (présence de deux inductances L par résonateur).The opposite inductances are connected mutually two by two at one of their ends in each resonator 6 (presence of two inductances L by resonator).

Afin de pouvoir fournir un contrôle automatique de l'assèchement, il peut être avantageusement prévu que la puissance du champ électrique émis par chaque résonateur 6 soit régulée par l'intermédiaire d'une ou de plusieurs sonde(s) 7 montée(s) sur ou dans la partie de mur ou de maçonnerie 2' à traiter et sensibles au taux d'humidité ou à un autre paramètre physique caractérisant cette partie 2', le signal de sortie SA de la ou de chaque sonde 7 étant délivré aux moyens 3, 4, 5 de génération du signal modulé alimentant le ou les résonateurs 6, en tant que paramètre de pilotage de la puissance dudit signal modulé.In order to provide an automatic control of drying, it can be advantageously provided that the power of the electric field emitted by each resonator 6 is regulated by means of one or more probe (s) 7 mounted on or in the part of wall or masonry 2 'to be treated and sensitive to the humidity level or to another physical parameter characterizing this part 2', the output signal SA of the or each probe 7 being delivered to the means 3, 4, 5 for generating the modulated signal supplying the resonator (s) 6, as a parameter for controlling the power of said modulated signal.

Comme le montre, à titre d'exemple de réalisation pratique simple et robuste, la figure 1 des dessins annexés, les moyens 3, 4, 5 de génération du signal modulé SM alimentant le ou les résonateur(s) 6 sont composés d'une unité transformateur/redresseur 3 connectée au secteur, d'un générateur 4 de signal impulsionnel SI alimenté par ladite unité 3, et d'un oscillateur 5, par exemple un oscillateur commandé en tension, recevant les signaux impulsionnels SI délivrés par ledit générateur 4, délivrant un signal modulé au(x) résonateur(s) 6 et, le cas échéant, piloté en termes de puissance du signal modulé délivré par ledit signal ou les signaux de sortie SA d'une ou de plusieurs sonde(s) 7 montée(s) sur ou dans la partie 2' de mur ou de maçonnerie à traiter, les différentes composantes 3, 4, 5 desdits moyens de génération étant préférentiellement installées dans un boîtier de protection 8 étanche.As shown by an example of simple and robust practical realization, the figure 1 of the accompanying drawings, the means 3, 4, 5 for generating the modulated signal SM supplying the resonator (s) 6 are composed of a transformer / rectifier unit 3 connected to the mains, a pulse generator 4 of pulsed signal SI. by said unit 3, and an oscillator 5, for example a voltage-controlled oscillator, receiving the pulse signals SI delivered by said generator 4, delivering a modulated signal to the resonator (s) 6 and, if appropriate, controlled in terms of the power of the modulated signal delivered by said signal or the SA output signals from one or more probe (s) 7 mounted on or in the part 2 'of wall or masonry to be treated, the different components 3, 4, 5 of said generating means being preferably installed in a sealed protective housing 8.

Ce boîtier peut être accroché au mur ou à l'ouvrage de maçonnerie à traiter, ou en variante être monté dans une niche ou être noyé dans ce dernier.This housing can be hung on the wall or the masonry work to be treated, or alternatively be mounted in a recess or be embedded in the latter.

Les circuits électroniques du générateur d'impulsions et de l'oscillateur peuvent être constitués par des composants intégrés ou classiques disponibles dans le commerce, tels que ceux utilisés pour la réalisation de multivibrateurs astables ou de circuits du même type. La constitution de tels circuits est connue et ne sera donc pas décrite plus avant dans la présente.The electronic circuits of the pulse generator and the oscillator may be constituted by integrated or conventional components that are commercially available, such as those used for producing astable multivibrators or circuits of the same type. The constitution of such circuits is known and will not be described further herein.

En vue de combattre les effets d'éventuels champs électromagnétiques d'origine tellurique, provoquant ou favorisant les remontées capillaires, le dispositif 1 peut également comprendre ou être associé à au moins un résonateur passif 9 neutralisant les rayonnements micro-ondes affectant le volume d'action du ou des champ(s) électrique(s) émis par le ou les résonateur(s) 6, en particulier ceux ayant une fréquence comprise entre 2,10 et 2,50 GHz.In order to combat the effects of possible electromagnetic fields of telluric origin, causing or promoting the capillary rise, the device 1 can also include or be associated with at least one passive resonator 9 neutralizing the microwave radiation affecting the volume of action of the electric field (s) emitted by the resonator (s) 6, in particular those having a frequency between 2.10 and 2.50 GHz.

Ce ou ces résonateur(s) passif(s) 9 fournit(ssent) une action supplémentaire et complémentaire de celle des résonateurs actifs 6, en agissant dans une autre gamme de fréquences et sans interférer avec l'action desdits résonateurs actifs.This or these passive resonator (s) 9 provides (ssent) an additional action complementary to that of the active resonators 6, acting in a different frequency range and without interfering with the action of said active resonators.

L'invention a également pour objet un procédé pour stopper les remontées d'eau et d'humidité par capillarité dans les murs, ouvrages de maçonnerie ou analogues, mettant préférentiellement en oeuvre au moins un dispositif 1 du type décrit ci-dessus.The invention also relates to a method for stopping the rise of water and moisture by capillarity in walls, masonry structures or the like, preferably implementing at least one device 1 of the type described above.

Ce procédé consiste à soumettre, de manière séquentielle ou continue, une partie 2' au moins d'un mur ou d'un ouvrage de maçonnerie 2 à traiter à un champ électrique émis par au moins un résonateur 6 alimenté par des moyens 3, 4, 5 de génération d'un signal modulé SM formé par une porteuse dont la fréquence est comprise entre 25 et 65 kHz ou entre 143 et 150 KHz et qui est modulée par un signal modulant SI dont la fréquence est comprise entre 45 et 49 Hz, le ou les champ(s) électrique(s) émis étant apte(s) à modifier les caractéristiques électriques et l'orientation des molécules d'eau présentes dans la partie de mur ou de maçonnerie 2' affectée par ledit champ, ainsi que celles des surfaces capillaires de ladite partie 2' en contact avec ces molécules d'eau.This method consists in subjecting, sequentially or continuously, at least part 2 'of a wall or a masonry structure 2 to be treated to an electric field emitted by at least one resonator 6 fed by means 3, 4 Generating a modulated signal SM formed by a carrier whose frequency is between 25 and 65 kHz or between 143 and 150 KHz and which is modulated by a modulating signal IF whose frequency is between 45 and 49 Hz, the electric field or fields emitted being capable of modifying the electrical characteristics and the orientation of the water molecules present in the portion of wall or masonry 2 'affected by said field, as well as those capillary surfaces of said portion 2 'in contact with these water molecules.

Avantageusement, il peut être prévu de faire varier la fréquence de la porteuse du signal modulé SM et à utiliser un signal modulant SI ayant une fréquence d'environ 47 Hz, préférentiellement constitué d'impulsions de forme carrée.Advantageously, it is possible to vary the frequency of the carrier of the modulated signal SM and to use a modulating signal SI having a frequency of approximately 47 Hz, preferably consisting of square-shaped pulses.

Préférentiellement, la porteuse du signal modulé SM alimentant le ou les résonateur(s) 6 présente une fréquence alternativement comprise dans la plage 25 à 65 KHz et dans la plage 143 à 150 KHz, ladite fréquence de porteuse étant en outre préférentiellement variable dans ces deux plages fréquentielles de manière à balayer au moins une partie de chacune de ces deux plages.Preferably, the carrier of the modulated signal SM feeding the resonator (s) 6 has a frequency alternately in the range 25 to 65 KHz and in the range 143 to 150 KHz, said carrier frequency being moreover preferably variable in these two frequency ranges so as to scan at least a portion of each of these two ranges.

La variation de la fréquence peut par exemple résulter de l'instabilité propre en terme de fréquence de certains types de transistors utilisés (par exemple ceux connus sous la désignation BC,...). Cette instabilité et la variabilité en fréquence résultante peuvent encore être augmentées par l'absence d'un étage stabilisateur de tension.The variation of the frequency can for example result from the inherent instability in terms of frequency of certain types of transistors used (for example those known under the designation BC, ...). This instability and the resulting frequency variability can be further enhanced by the absence of a voltage stabilizing stage.

En vue d'ajuster l'intensité du traitement au degré d'assèchement de la partie 2 de mur ou de maçonnerie, et à son évolution, le procédé peut aussi consister à réguler la puissance du champ électrique produit et émis par le ou chaque résonateur 6 par l'intermédiaire d'une ou de plusieurs sonde(s) 7 montée(s) sur ou dans la partie de mur ou de maçonnerie 2' à traiter, et sensibles au taux d'humidité ou à un autre paramètre physique caractérisant cette partie 2', le signal de sortie SA de la ou de chaque sonde 7 étant délivré aux moyens 3, 4, 5 de génération du signal modulé alimentant le ou les résonateurs 6, en tant que paramètre de pilotage de la puissance dudit signal modulé SM.In order to adjust the intensity of the treatment to the degree of dewatering of the wall or masonry part 2, and to its evolution, the method may also consist in regulating the power of the electric field produced and emitted by the or each resonator 6 via one or more probe (s) 7 mounted (s) on or in the wall or masonry portion 2 'to be treated, and sensitive to the humidity or other physical parameter characterizing this part 2 ', the output signal SA of the or each probe 7 being delivered to the means 3, 4, 5 for generating the modulated signal supplying the resonator (s) 6, as a parameter for controlling the power of said modulated signal SM .

Les sondes 7 mises en oeuvre peuvent par exemple être de deux types différents.The probes 7 used may for example be of two different types.

Un premier type consiste en des sondes d'ambiance, par exemple à capteurs capacitifs, destinées à être disposées dans des cavités ménagées dans la maçonnerie à traiter. Les données de mesure recueillies sont traitées, puis délivrées aux circuits électroniques (oscillateur ou autre) du dispositif pour servir de paramètre de régulation. Ce premier type de sondes est recommandé pour les murs à fortes concentrations en sels minéraux.A first type consists of room probes, for example capacitive sensors, intended to be arranged in cavities formed in the masonry to be treated. The measurement data collected are processed and then delivered to the electronic circuits (oscillator or other) of the device to serve as a control parameter. This first type of probe is recommended for walls with high concentrations of mineral salts.

Un second type de sondes utilisé consiste en des sondes de contact à deux électrodes, mesurant la résistivité du mur (adaptées pour les murs à faible concentration de sels minéraux). Les données de mesure recueillies peuvent être délivrées directement aux circuits électroniques du dispositif.A second type of probe used consists of two-electrode contact probes, measuring the resistivity of the wall (suitable for walls with low concentration of mineral salts). Measurement data collected can be delivered directly to the electronic circuits of the device.

Selon une caractéristique additionnelle de l'invention, le procédé consiste éventuellement à neutraliser également les rayonnements micro-ondes affectant le mur ou la maçonnerie à traiter, en particulier ceux ayant une fréquence comprise entre 2,10 et 2,50 GHz, par la mise en place d'au moins un résonateur passif 9 au voisinage de ladite partie de mur ou de maçonnerie 2' à traiter.According to an additional characteristic of the invention, the method optionally consists in also neutralizing the microwave radiation affecting the wall or the masonry to be treated, in particular those having a frequency of between 2.10 and 2.50 GHz, by setting in place of at least one passive resonator 9 in the vicinity of said wall or masonry portion 2 'to be treated.

Ce ou ces résonateur(s) passif(s) 9 formant piège(s) à micro-ondes peut(vent) par exemple être disposé(s) dans un espace disponible dans le boîtier 8 renfermant le dispositif.This or these passive resonator (s) forming a microwave trap (s) may (for example) be arranged in a space available in the housing 8 enclosing the device.

Certains aspects particuliers de l'invention, ainsi que leurs implications, sont décrits de manière plus détaillée dans ce qui suit.Certain particular aspects of the invention, as well as their implications, are described in more detail in the following.

Il convient de noter tout d'abord que les moyens actifs 3, 4, 5, 6 mis en oeuvre par l'invention développent de faibles puissances dans des fréquences favorables à l'usage prévu de manière à supprimer tout risque de nocivité ou conséquences biologiques néfastes sur les humains et les animaux.It should be noted first of all that the active means 3, 4, 5, 6 implemented by the invention develop low powers in frequencies favorable to the intended use so as to eliminate any risk of harmfulness or biological consequences. harmful to humans and animals.

A titre d'indication, une puissance utile émise de quelques milliwatts est généralement suffisante pour obtenir les résultats d'assèchement souhaités. A titre comparatif, cette puissance est environ 100 à 200 fois moins élevée que celle des téléphones portables du type GSM (généralement environ 2 W) et plus de 1 000 fois moins élevée que celle des relais GSM (15 W).As an indication, a useful output power of a few milliwatts is usually sufficient to obtain the desired drying results. For comparison, this power is about 100 to 200 times lower than that of mobile phones type GSM (usually about 2 W) and more than 1,000 times lower than that of GSM relays (15 W).

On se situe donc à un niveau en puissance très inférieur aux normes CEM (compatibilité électromagnétique).It is therefore at a power level much lower than the EMC standards (electromagnetic compatibility).

Les recherches menées par l'inventeur ont démontré que les meilleurs résultats étaient obtenus par génération de champs électromagnétiques de fréquences basses situées entre 25 et 65 kHz, d'une part, et entre 143 et 150 kHz, d'autre part, modulés par de brèves impulsions à signaux carrés de l'ordre de 47 Hz.The research carried out by the inventor showed that the best results were obtained by generating low frequency electromagnetic fields between 25 and 65 kHz, on the one hand, and between 143 and 150 kHz, on the other, modulated by short pulses with square signals of the order of 47 Hz.

Cette fréquence naturelle de 47 Hz favorable à l'assèchement correspond à la moyenne des. fréquences entre la surface de la terre et l'ionosphère (la fréquence de 50 Hz omniprésente est à éviter).This natural frequency of 47 Hz favorable to drying corresponds to the average of. frequencies between the earth's surface and the ionosphere (the ubiquitous 50 Hz frequency is to be avoided).

Une fréquence comprise entre 45 à 49 Hz a été choisie pour son efficacité et parce qu'elle est à la base du développement de tout organisme vivant à la surface de la Terre. Cette fréquence a été vérifiée par des mesures et confirmée par des calculs.A frequency between 45 to 49 Hz has been chosen for its efficiency and because it is the basis of the development of any organism living on the surface of the Earth. This frequency has been verified by measurements and confirmed by calculations.

Par ailleurs, des essais supplémentaires ont permis de vérifier que l'utilisation de fréquences variables était bénéfique sur le plan de l'efficacité du dispositif 1 contre les remontées capillaires.Moreover, additional tests made it possible to verify that the use of variable frequencies was beneficial in terms of the efficiency of the device 1 against capillary rise.

Ainsi, selon l'invention il est très avantageux de générer des champs électromagnétiques à fréquence variable comprise soit entre 25 et 65 kHz, soit entre 143 et 150 kHz, modulés par de brèves impulsions de signaux carrés de l'ordre de 47 Hz, ou encore de générer alternativement des champs électromagnétiques dans les deux bandes de fréquences ci-dessus, ce qui renforce encore l'efficacité dans l'action contre les remontées capillaires.Thus, according to the invention it is very advantageous to generate electromagnetic fields with a variable frequency of between 25 and 65 kHz, or between 143 and 150 kHz, modulated by short pulses of square signals of the order of 47 Hz, or alternatively to generate electromagnetic fields alternately in the two frequency bands above, which further enhances the effectiveness in the action against capillary rise.

Comme déjà décrit précédemment, les champs électromagnétiques ainsi créés alimentent un ou deux résonateurs 6 constitués d'un ou de deux circuit(s) oscillant(s) LC parallèle(s) à inductances opposées se présentant sous la forme de circuits imprimés disposés parallèlement. Les inductances peuvent également être bobinées à l'aide de fils en cuivre émaillé.As already described above, the electromagnetic fields thus created supply one or two resonators 6 consisting of one or two LC parallel oscillating circuit (s) with opposite inductances in the form of printed circuits arranged in parallel. The inductors can also be wound using enamelled copper wires.

Les champs électriques émis par les résonateurs 6 induisent une énergie faible, mais suffisante pour modifier les caractéristiques électriques et l'orientation des molécules d'eau (leur liaison, leur orientation et leur cohésion) et des surfaces des capillaires des murs 2 en contact avec ces dernières, de manière à ce que les molécules d'eau et les ions migrent en direction du sol. La tension superficielle de l'eau dans les capillaires est également modifiée, ce qui réduit l'adhérence des molécules d'eau sur les parois desdits capillaires.The electric fields emitted by the resonators 6 induce a weak energy, but sufficient to modify the electrical characteristics and the orientation of the water molecules (their connection, orientation and cohesion) and the surfaces of the capillaries of the walls 2 in contact with the latter, so that water molecules and ions migrate towards the ground. The surface tension of the water in the capillaries is also modified, which reduces the adhesion of the water molecules to the walls of said capillaries.

Le phénomène naturel de poussée osmotique à l'origine des remontées capillaires est ainsi stoppé.The natural phenomenon of osmotic pressure at the origin of the capillary rise is thus stopped.

La présente invention prévoit en option un système de contrôle de l'assèchement au moyen d'un système d'asservissement par sondes 7 disposées dans les murs 2 de façon à piloter le fonctionnement du dispositif 1. La baisse du taux d'humidité dans les murs entraîne automatiquement la diminution de la puissance émise, ce qui réduit encore la puissance nécessaire à l'efficacité du dispositif 1.The present invention optionally provides a control system for drying by means of a probes control system 7 arranged in the walls 2 so as to control the operation of the device 1. The lowering of the moisture content in the walls automatically reduces the power output, which further reduces the power required for the efficiency of the device 1.

Enfin, dans certaines configurations géologiques, on a constaté la présence de champs électromagnétiques d'origine tellurique dans la gamme des micro-ondes ayant également une action sur les remontées capillaires.Finally, in some geological configurations, the presence of electromagnetic fields of telluric origin in the range of microwaves also having an action on the capillary rise.

La présente invention prévoit pour cette version, en option, un piège à micro-ondes agissant par interférence (déphasage de 180° par rapport à l'onde captée).The present invention provides for this version, optionally, a microwave trap acting by interference (phase shift of 180 ° with respect to the sensed wave).

Ce piège est constitué d'un résonateur passif 9 captant et neutralisant les micro-ondes dans une plage de fréquences de 2,10 à . 2,50 GHz.This trap consists of a passive resonator 9 sensing and neutralizing microwaves in a frequency range of 2.10 to. 2.50 GHz.

Des formes de réalisation possibles de tels résonateurs passifs 9 sont représentées sur les figures 2A, 2B et 2C.Possible embodiments of such passive resonators 9 are shown in FIGS. Figures 2A, 2B and 2C .

Comme le montre plus précisément la figure 2C, un résonateur passif 9 peut par exemple comprendre un conducteur tubulaire fendu entourant un brin de conducteur filaire, les deux conducteurs étant montés coaxialement et assemblés par un diélectrique à l'une au moins de leurs extrémités.As shown more specifically Figure 2C a passive resonator 9 may for example comprise a split tubular conductor surrounding a strand of wire conductor, the two conductors being mounted coaxially and assembled by a dielectric at at least one of their ends.
