Definitions
- the present invention relates to a surface treatment device, particularly suitable for the treatment of surfaces such as a floor, a ceiling, a wall or a column for example, covered with a coating comprising one or more toxic products such as asbestos, lead (Pb), PCBs (polychlorinated biphenyls) and polycyclic aromatic hydrocarbons (PAHs) for example, present in many products with many applications such as floor and ceiling coverings, wall coverings (paint, insulation, etc ...), road surfaces, bituminous adhesives, vapor barriers, waterproofing materials, the walls of treatment plants, the walls of water towers, or the like.
- toxic products such as asbestos, lead (Pb), PCBs (polychlorinated biphenyls) and polycyclic aromatic hydrocarbons (PAHs)
- Pb toxic products
- PCBs polychlorinated biphenyls
- PAHs polycyclic aromatic hydrocarbons
- Asbestos has been known for over two thousand years and has long been used in many materials and products, due to its acoustic, thermal, heat and fire resistance, chemical inertness, its mechanical resistance and its rot-proofness.
- the regulation states that a worker must not inhale more than 0.1 fibers per cm 3 over an hour.
- the pathologies, mainly lung cancers, can be declared until more than fifty years after the first exposures to asbestos fibers. The adverse effects on human health have therefore led to a control and a gradual reduction of its use, followed by a complete ban since 1 January 1997, by Decree No. 96-1133 of 24 December 1996 on the ban on asbestos, taken under the Labor Code and the Consumer Code.
- asbestos removal operations take place in several constraining stages because they must respect safety standards for both the worker and the environment.
- the worker must indeed be provided with a combination and a respiratory system so as not to inhale friable asbestos dust, extremely toxic.
- His work is performed in a confined area with access to the confined area by an airlock, divided into several compartments including two showers.
- This confined area has an air pressure lower than that of the outside air so that in the event of a leak, it is the outside air that enters the confined area, and not the other way around.
- This confined area is made by means of two polyane films which protect the surfaces not to be dismantled.
- An air renewal system must also be provided.
- Asbestos removed from its support can undergo a treatment to make it inert, that is to say modify it to make it nontoxic to humans.
- This treatment may consist of a vitrification, as described in the patents FR 2,853,846 or FR 2 690 093 , the asbestos waste being incorporated in a particular oven to achieve very high temperatures.
- the waste may be previously packaged, for example by pre-bagging, as described in the patent FR 2,746,037 .
- a surface asbestos removal device comprising an apparatus for projecting a high-pressure liquid jet, said pressure being between 1000 and 2000 bar, at a distance of approximately one meter from the surface to be treated, means for pumping separate to suck the moisture-laden residues resulting from the degradation of the coating fallen on the ground, a filtration system consisting of a filter press and possibly a second filtration system.
- the value is greater than or equal to 60 times the VLP and less than 250 times the VLP.
- each primary carriage comprises two jaws enclosing the section of one of the tubular rails and can be moved relative to each other, away or in proximity, via a jack system .
- a first jaw is released, away from the second jaw, and then tightened.
- Successively the second jaw is released, close to the first, then tightened.
- the rail carrying the tool therefore moves on the tubular rails.
- this solution proposes a surface treatment device, particularly suitable for the treatment of surfaces covered with a coating comprising one or more toxic products.
- the surface treatment device of the document WO 2010/140952 is not suitable for treating oblique surfaces, for example under a staircase. Indeed, the movement of the surface treatment tool is only horizontally, orthogonal to the tubular rails on which the device moves.
- One of the aims of the invention is therefore to overcome these disadvantages by providing a surface treatment device, particularly suitable for the treatment of any type of surfaces such as a floor, a ceiling, a wall or a column by for example, covered with a coating comprising one or more toxic products, simple and inexpensive design, and also allowing rapid removal of said products on inaccessible surfaces, such as surfaces under stairs for example.
- Another object of the invention is to provide a surface treatment device for rapid removal of products safely for workers and the environment.

Description
La présente invention concerne un dispositif de traitement de surfaces, particulièrement adapté pour le traitement de surfaces telles qu'un sol, un plafond, un mur ou une colonne par exemple, recouvertes d'un revêtement comportant un ou plusieurs produits toxiques tels que l'amiante, le plomb (Pb), les PCB (biphényles polychlorés) et les hydrocarbures polycycliques aromatiques (HAP) par exemple, présents dans de nombreux produits ayant de nombreuses applications telles que les revêtements de sols et plafonds, les revêtements de mur (peinture, isolation, etc...), les revêtements routiers, les colles bitumineuses, les pare-vapeurs, les matériaux assurant l'étanchéité, les parois des stations d'épuration, les parois des châteaux d'eau, ou similaires.The present invention relates to a surface treatment device, particularly suitable for the treatment of surfaces such as a floor, a ceiling, a wall or a column for example, covered with a coating comprising one or more toxic products such as asbestos, lead (Pb), PCBs (polychlorinated biphenyls) and polycyclic aromatic hydrocarbons (PAHs) for example, present in many products with many applications such as floor and ceiling coverings, wall coverings (paint, insulation, etc ...), road surfaces, bituminous adhesives, vapor barriers, waterproofing materials, the walls of treatment plants, the walls of water towers, or the like.
L'amiante est connue depuis plus de deux mille ans et elle a longtemps été employée dans de nombreux matériaux et produits, en raison de ses propriétés d'isolation acoustique, thermique, de résistance à la chaleur et au feu, de son inertie chimique, de sa résistance mécanique et de son imputrescibilité. Toutefois, les caractéristiques physico-chimiques de l'amiante, associées à une capacité à se fractionner en fibres fourchues microscopiques pour atteindre les alvéoles pulmonaires, et même migrer jusqu'à la plèvre, font que l'inhalation importante de fibres d'amiante est dangereuse. La réglementation fixe qu'un travailleur ne doit pas inhaler plus de 0,1 fibres par cm3 sur une heure. Les pathologies, essentiellement des cancers du poumon, peuvent se déclarer jusqu'à plus de cinquante ans après les premières expositions aux fibres d'amiante. Les effets néfastes sur la santé humaine ont donc conduit à un contrôle puis à une réduction progressive de son utilisation, suivie d'une interdiction totale depuis le 1er janvier 1997, par le décret n° 96-1133 du 24 décembre 1996 relatif à l'interdiction de l'amiante, pris en application du code du travail et du code de la consommation.Asbestos has been known for over two thousand years and has long been used in many materials and products, due to its acoustic, thermal, heat and fire resistance, chemical inertness, its mechanical resistance and its rot-proofness. However, the physicochemical characteristics of asbestos, associated with an ability to split into microscopic split fibers to reach the pulmonary alveoli, and even migrate to the pleura, make the important inhalation of asbestos fibers dangerous. The regulation states that a worker must not inhale more than 0.1 fibers per cm 3 over an hour. The pathologies, mainly lung cancers, can be declared until more than fifty years after the first exposures to asbestos fibers. The adverse effects on human health have therefore led to a control and a gradual reduction of its use, followed by a complete ban since 1 January 1997, by Decree No. 96-1133 of 24 December 1996 on the ban on asbestos, taken under the Labor Code and the Consumer Code.
Actuellement, les opérations de désamiantage se déroulent en plusieurs étapes contraignantes, car elles doivent respecter des normes de sécurité à la fois pour l'ouvrier et pour l'environnement. L'ouvrier doit en effet être muni d'une combinaison et d'un système respiratoire afin de ne pas inhaler de poussières d'amiante friables, extrêmement toxiques. Son travail est réalisé dans une zone confinée avec accès à ladite zone confinée par un sas, divisé en plusieurs compartiments dont deux douches. Cette zone confinée présente une pression d'air inférieure à celle de l'air extérieur de manière à ce qu'en cas de fuite, ce soit l'air extérieur qui entre dans la zone confinée, et non l'inverse. Cette zone confinée est réalisée au moyen de deux films de polyane qui protègent les surfaces à ne pas désamianter. Un système de renouvellement de l'air doit également être prévu.At present, asbestos removal operations take place in several constraining stages because they must respect safety standards for both the worker and the environment. The worker must indeed be provided with a combination and a respiratory system so as not to inhale friable asbestos dust, extremely toxic. His work is performed in a confined area with access to the confined area by an airlock, divided into several compartments including two showers. This confined area has an air pressure lower than that of the outside air so that in the event of a leak, it is the outside air that enters the confined area, and not the other way around. This confined area is made by means of two polyane films which protect the surfaces not to be dismantled. An air renewal system must also be provided.
Toutefois, il est fréquent que la combinaison et/ou le système respiratoire deviennent inopérants au cours du chantier, en raison d'une déchirure de la combinaison ou d'un dysfonctionnement du système respiratoire par exemple de sorte qu'il est fréquent que les ouvriers respirent plus de 0,1 fibres par cm3 sur une heure s'exposant à des maladies mortelles. De plus, malgré toutes les précautions prises lors du confinement, ledit confinement nécessitant beaucoup de temps pour sa mise en place ainsi que des vérifications obligatoires qui grèvent considérablement le coût des chantiers de désamiantage, des fibres d'amiante peuvent s'échapper de la zone confinement mettant ainsi la mise en danger des personnes extérieures au chantier qui sont susceptibles de respirer, sans le savoir, des fibres d'amiante.However, it is common that the combination and / or the respiratory system become inoperative during the construction site, because of a tear in the suit or a malfunction of the respiratory system for example so that it is common for workers breathe more than 0.1 fibers per cm 3 over an hour exposing oneself to deadly diseases. Moreover, despite all the precautions taken during the confinement, said confinement requiring a lot of time for its implementation as well as mandatory verifications which considerably increase the cost of asbestos removal sites, asbestos fibers can escape from the zone. containment putting the endangerment of people outside the site who are likely to breathe, without knowing it, asbestos fibers.
L'amiante ainsi enlevée de son support peut subir un traitement permettant de le rendre inerte, c'est-à-dire le modifier pour le rendre non toxique pour l'homme. Ce traitement peut consister en une vitrification, telle que décrite dans les brevets
Cependant, c'est lors de l'enlèvement de l'amiante de son support que les risques d'inhalation sont les plus importants. A cet égard, il est usuel d'utiliser des grattoirs et/ou des ponceuses pour détacher l'amiante de son support, ce qui produit une grande quantité de poussière d'amiante qui peut se disperser dans l'air ambiant. Les méthodes courantes d'enlèvement de l'amiante nécessitent des conditions de sécurité draconiennes sans pour autant détoxifier le produit.However, it is during the removal of asbestos from its support that the risks of inhalation are the most important. In this respect, it is usual to use scrapers and / or sanders to remove asbestos from its support, which produces a large amount of asbestos dust that can disperse in the ambient air. Common methods of removing asbestos require stringent safety conditions without detoxifying the product.
De nombreuses solutions alternatives ont été trouvées afin de permettre en une seule étape l'enlèvement des déchets tout en les rendant inertes. C'est le cas notamment du brevet
Toutefois, ce type de procédé n'est plus mis en oeuvre compte tenu du risque chimique qu'il fait encourir aux ouvriers et à l'environnement.However, this type of process is no longer implemented given the chemical risk it incurs to workers and the environment.

Outre le coût élevé de l'azote liquide, ce type de procédé nécessite une étape de traitement supplémentaire des fibres d'amiante qui grève le coût des chantiers.In addition to the high cost of liquid nitrogen, this type of process requires an additional treatment step of asbestos fibers that strike the cost of building sites.

Tous ces procédés et dispositifs mettant en oeuvre ces procédés présentent l'inconvénient, outre d'être onéreux, de produire une quantité de poussières d'amiante trop élevée de sorte que le risque pour les ouvriers et l'environnement reste trop important. De plus, le décret n°2012-639 impose que, à compter du 1er juillet 2015, la concentration moyenne en fibres d'amiante, sur huit heures de travail, ne dépasse pas dix fibres par litre. Par conséquent, c'est une division par dix, du taux précédemment autorisé et qui plaçait la limite à 100 fibres par litre. Trois catégories de classification sont alors mises en place. Au « premier niveau », l'empoussièrement est inférieur à la valeur limite d'exposition professionnelle dite VLP. Au « deuxième niveau » la valeur est supérieure ou égale à la VLP et inférieure à 60 fois la VLP. Enfin au « troisième niveau » la valeur est supérieure ou égale à 60 fois la VLP et inférieure à 250 fois la VLP. Ainsi, cette diminution de la valeur limite d'exposition professionnelle (VLP) aura comme conséquence immédiate une augmentation du coût de réalisation du désamiantage avec les procédés de désamiantage de l'art antérieur.All these methods and devices implementing these methods have the disadvantage, besides being expensive, to produce a quantity of asbestos dust too high so that the risk for workers and the environment remains too high. In addition, Decree No. 2012-639 requires that, as of 1 July 2015, the average asbestos fiber concentration over eight working hours should not exceed ten fibers per liter. As a result, it is a division of the previously authorized rate by ten and placing the limit at 100 fibers per liter. Three categories of classification are then put in place. At the "first level", the dust is lower than the occupational exposure limit value, VLP. At the "second level" the value is greater than or equal to the VLP and less than 60 times the VLP. Finally, at the "third level" the value is greater than or equal to 60 times the VLP and less than 250 times the VLP. Thus, this reduction in the occupational exposure limit value (VLP) will have the immediate consequence of increasing the cost of performing asbestos removal with the asbestos removal processes of the prior art.
Par ailleurs, dans les bâtiments, il existe d'autres produits susceptibles de constituer un risque pour la santé et qui doivent être retirés en toute sécurité pour préserver la santé des ouvriers lors de la déconstruction notamment. C'est le cas notamment du plomb susceptible de causer du saturnisme et présent dans de nombreux revêtements de surface comme les peintures anciennes notamment, les PCB (biphényles polychlorés) qui sont des produits chimiques similaires à la dioxine et que l'on trouve dans les joints de dilatation ainsi que dans certains revêtements, les hydrocarbures polycycliques aromatiques (HAP) qui sont des polluants organiques persistants et qui sont présents dans les produits fabriqués à partir de bitume tels que les revêtements routiers, les colles bitumineuses, les pare-vapeurs, les matériaux assurant l'étanchéité, les parois des stations d'épuration, les parois des châteaux d'eau, etc..., et les produits radioactifs que l'on trouve notamment sur les tours de refroidissement, les enceintes de réacteurs ou similaire des centrales nucléaires.In addition, in buildings, there are other products that may pose a risk to health and must be removed safely to preserve the health of workers during the deconstruction in particular. This is particularly the case for lead, which is likely to cause lead poisoning, and which is present in many surface coatings, such as old paints, PCBs (polychlorinated biphenyls), which are chemicals similar to dioxin and which are found in expansion joints and in some coatings, polycyclic aromatic hydrocarbons (PAHs) that are persistent organic pollutants and are present in products made from bitumen such as road surfacing, bituminous adhesives, vapor barriers, sealing materials, the walls of treatment plants, the walls of water towers, etc ..., and radioactive products that are found in particular on cooling towers, reactor enclosures or similar nuclear center.
Il existe donc un besoin pour un dispositif pour le traitement de surfaces comportant un ou plusieurs produits toxiques procurant un retrait desdits produits en toute sécurité pour les ouvriers et l'environnement.There is therefore a need for a device for the treatment of surfaces comprising one or more toxic products providing a withdrawal of said products safely for workers and the environment.
Le document
De cette manière, cette solution propose un dispositif de traitement de surfaces, particulièrement adapté pour le traitement de surfaces recouvertes d'un revêtement comportant un ou plusieurs produits toxiques.In this way, this solution proposes a surface treatment device, particularly suitable for the treatment of surfaces covered with a coating comprising one or more toxic products.
Cependant, cette solution présente quelques inconvénients inhérents à sa structure. En effet, le dispositif de traitement de surface du document
Un autre inconvénient réside dans le fait que le déplacement du rail portant l'outil est lent et saccadé et présente des risques de glissement, en particulier lors du traitement de surface qui projette de l'eau à forte pression venant notamment mouiller les rails tubulaires. Ainsi, cette solution ne permet pas un retrait rapide desdits produits en toute sécurité pour les ouvriers et l'environnement.Another disadvantage lies in the fact that the movement of the rail carrying the tool is slow and jerky and presents risks of slipping, in particular during the surface treatment which projects high pressure water especially from wetting the tubular rails. Thus, this solution does not allow rapid removal of said products safely for workers and the environment.
L'un des buts de l'invention est donc de remédier à ces inconvénients en proposant un dispositif de traitement de surfaces, particulièrement adapté pour le traitement de tout type de surfaces telles qu'un sol, un plafond, un mur ou une colonne par exemple, recouvert d'un revêtement comportant un ou plusieurs produits toxiques, de conception simple et peu onéreuse, et permettant également un retrait rapide desdits produits sur des surfaces peu accessibles, telles que des surfaces situées sous des escaliers par exemple.One of the aims of the invention is therefore to overcome these disadvantages by providing a surface treatment device, particularly suitable for the treatment of any type of surfaces such as a floor, a ceiling, a wall or a column by for example, covered with a coating comprising one or more toxic products, simple and inexpensive design, and also allowing rapid removal of said products on inaccessible surfaces, such as surfaces under stairs for example.
Un autre objectif de l'invention est de fournir un dispositif de traitement de surfaces permettant un retrait rapide des produits en toute sécurité pour les ouvriers et l'environnementAnother object of the invention is to provide a surface treatment device for rapid removal of products safely for workers and the environment.
Pour résoudre les problème précités, il a été mis au point un dispositif de traitement d'une surface, selon la revendication 1, telle qu'une surface plane et/ou incurvée conforme à l'état de la technique en ce qu'il comprend au moins un outil de traitement de surface monté sur un chariot motorisé secondaire apte à se déplacer le long d'un rail entre deux chariots primaires déplaçables sur des tubes, tels que des tubes droits ou incurvés, de préférence parallèles et de section circulaire.In order to solve the aforementioned problems, a surface treatment device according to
On comprend bien qu'un ouvrier pourra manipuler le dispositif à distance évitant toute inhalation des éventuels produits toxiques. Le dispositif est notamment apte à traiter des surfaces planes lorsque les deux tubes sur lesquelles sont montés les deux chariots primaires sont droits, et apte à traiter des surfaces incurvées lorsque lesdits tubes sont incurvés.It is understandable that a worker can manipulate the device remotely avoiding inhalation of any toxic products. The device is particularly suitable for treating flat surfaces when the two tubes on which are mounted the two primary carriages are straight, and able to treat curved surfaces when said tubes are curved.
Conformément à l'invention, les chariots primaires sont montés sur le rail, d'une part, de manière pivotante autour d'un axe orthogonal audit rail et, d'autre part, de manière coulissante le long dudit rail.According to the invention, the primary carriages are mounted on the rail, on the one hand, pivotally about an axis orthogonal to said rail and, on the other hand, slidably along said rail.
De cette manière, chaque chariot primaire peut pivoter par rapport au rail portant l'outil et se déplacer le long du rail portant l'outil. En d'autres termes, les chariots peuvent se déplacer indépendamment l'un de l'autre sur les tubes. Il s'ensuit que le rail portant l'outil peut être disposé en oblique, pour notamment permettre un traitement rapide et efficace de surfaces difficiles d'accès, telles que des surfaces situées sous des escaliers par exemple. De plus, les tubes sur lesquels se déplacent les chariots primaires peuvent ne pas être parallèles, puisque lesdits chariots primaires ont la capacité de se rapprocher ou de s'éloigner l'un de l'autre par coulissement le long du rail.In this way, each primary carriage can pivot relative to the rail carrying the tool and move along the rail carrying the tool. In other words, the carriages can move independently of one another on the tubes. It follows that the rail carrying the tool can be arranged obliquely, in particular to allow a fast and effective treatment of difficult to access surfaces, such as surfaces under stairs for example. In addition, the tubes on which the primary carriages move may not be parallel, since said primary carriages have the ability to move toward or away from one another by sliding along the rail.
Selon une forme de réalisation particulière, chaque charriot comporte un patin monté pivotant par rapport à l'axe solidaire dudit charriot et s'étendant dans une glissière longitudinale ménagée dans le rail.According to a particular embodiment, each carriage comprises a shoe pivotally mounted relative to the axis integral with said carriage and extending in a longitudinal slide formed in the rail.
Selon une autre caractéristique de l'invention, indépendamment du fait que les chariots primaires soient montés pivotants par rapport au rail et déplaçables le long de celui-ci pour traiter des surfaces en oblique, les chariots primaires sont motorisés et comprennent des moyens d'entrainement aptes à prendre appui sur les tubes, et à rouler le long desdits tubes pour déplacer lesdits charriots primaires.According to another characteristic of the invention, independently of the fact that the primary carriages are pivotally mounted relative to the rail and movable along it to treat oblique surfaces, the primary carriages are motorized and comprise drive means able to bear on the tubes, and to roll along said tubes to move said primary carriages.
Ainsi, les chariots primaires roulent sur les tubes par l'intermédiaire des moyens d'entrainement en appui sur lesdits tubes de sorte que le déplacement est rapide et les risques de glissement sont diminués. Les moyens d'entrainement sont toujours en contact et en appui avec la surface des tubes.Thus, the primary carriages roll on the tubes by means of drive means bearing on said tubes so that the movement is fast and the risk of slippage are reduced. The drive means are always in contact and in abutment with the surface of the tubes.
Selon une forme de réalisation particulière, lesdits moyens d'entrainement comprennent une chenille, telle qu'une chenille souple en caoutchouc ou en élastomère, s'étendant entre deux barbotins. De cette manière, la surface de contact entre les moyens d'entrainement et les tubes est augmentée et les risques de glissement sont diminués. La sécurité d'utilisation est optimale.According to a particular embodiment, said drive means comprise a track, such as a flexible rubber or elastomer track, extending between two sprockets. In this way, the contact surface between the drive means and the tubes is increased and the risks of sliding are reduced. The safety of use is optimal.
Par ailleurs, les moyens d'entrainement comportent au moins un patin maintenu en appui contre une paroi interne de la chenille par un ressort afin de tendre la chenille.Furthermore, the drive means comprise at least one pad held in abutment against an inner wall of the caterpillar by a spring in order to tension the crawler.
De plus, chaque chenille présente une paroi interne plane et une paroi externe de section transversale concave pour s'adapter au diamètre du tube.In addition, each track has a flat inner wall and an outer wall of concave cross section to fit the diameter of the tube.
Le rayon de courbure de la paroi extérieure de section transversale concave de la chenille est sensiblement égal au rayon de courbure du tube.The radius of curvature of the outer wall of concave cross section of the track is substantially equal to the radius of curvature of the tube.
Par ailleurs, au moins un des barbotins est entraîné par un moteur, ledit moteur consistant de préférence dans un moteur hydraulique.Furthermore, at least one of the sprockets is driven by a motor, said motor preferably consisting of a hydraulic motor.
Selon une forme de réalisation particulière, chaque chariot primaire est constitué d'au moins deux caissons, comportant de préférence une poignée, s'étendant parallèlement et reliés par des moyens d'écartement, l'un des caissons étant articulé au rail, et chaque caisson comportant des moyens d'entrainement dont l'un au moins est motorisé.According to a particular embodiment, each primary carriage consists of at least two boxes, preferably having a handle, extending parallel and connected by spacing means, one of the boxes being hinged to the rail, and each box comprising driving means of which at least one is motorized.
De préférence, ledit outil consiste dans une tête d'hydrodécapage, par exemple constituée d'un carter sensiblement cylindrique dans lequel s'étend une buse rotative munie de trous, ladite buse étant alimentée par de l'eau sous haute pression au moyen d'une conduite souple de manière à former des jets à la sortie des trous.Preferably, said tool consists of a hydrodécapage head, for example consisting of a substantially cylindrical casing in which extends a rotary nozzle provided with holes, said nozzle being fed with water under high pressure by means of a flexible pipe so as to form jets at the exit of the holes.
De manière avantageuse, le bord inférieur du carter comporte une brosse assurant l'étanchéité lorsque la tête d'hydrodécapage est plaquée contre la surface à traiter.Advantageously, the lower edge of the casing comprises a brush ensuring sealing when the hydrodécapage head is pressed against the surface to be treated.
Par ailleurs, ladite tête d'hydrodécapage comporte des conduites d'aspiration connectées à une source d'aspiration et débouchant dans le carter.Furthermore, said hydrodécapage head comprises suction lines connected to a suction source and opening into the housing.

Par souci de clarté, dans la suite de la description, les mêmes éléments ont été désignés par les mêmes références aux différentes figures. Par ailleurs, les différentes vues ne sont pas nécessairement tracées à l'échelle. De plus, le dispositif suivant l'invention est particulièrement destiné au désamiantage ; toutefois, il est bien évident que le dispositif suivant l'invention pourra trouver de nombreuses applications dans le traitement de surface comportant des produits toxiques sans pour autant sortir du cadre de l'invention. De manière non limitative, lesdits produits toxiques pourront consister notamment dans le plomb (Pb), les PCB (biphényles polychlorés) et les hydrocarbures polycycliques aromatiques (HAP) qui sont présents dans de nombreux produits ayant de nombreuses applications telles que les revêtements de sols et plafonds, les revêtements de mur (peinture, isolation, etc...), les revêtements routiers, les colles bitumineuses, les pare-vapeurs, les matériaux assurant l'étanchéité, les parois des stations d'épuration, les parois des châteaux d'eau, etc...For the sake of clarity, in the remainder of the description, the same elements have been designated by the same references in the various figures. In addition, the different views are not necessarily drawn to scale. In addition, the device according to the invention is particularly intended for asbestos removal; However, it is obvious that the device according to the invention can find many applications in the surface treatment with toxic products without departing from the scope of the invention. In a nonlimiting manner, said toxic products may consist in particular of lead (Pb), PCBs (polychlorinated biphenyls) and polycyclic aromatic hydrocarbons (PAHs) which are present in many products having many applications such as floor coverings and ceilings, wall coverings (paint, insulation, etc.), road surfaces, bituminous adhesives, vapor barriers, waterproofing materials, walls of wastewater treatment plants, walls of castles water, etc ...
