Más en particular, la invención propone un sistema mediante el que resulta posible dotar a un tanque ya instalado, de tipo soterrado, destinado al almacenamiento de determinados productos líquidos, tales como los derivados del petróleo, construido con pared simple, de una doble pared para convertirlo en un tanque intrínsecamente seguro, con la provisión de una cámara intersticial intermedia realizada a base de un material poroso, y mediante la que resulta posible identificar las eventuales fugas de producto almacenado que en su caso pudieran producirse, con la particularidad de que la mencionada cámara intersticial consiste en una capa entre ambas paredes obtenida a partir de materiales de desecho, tales como materiales elastoméricos de tipo caucho, ya sea natural o ya sea sintético.More particularly, the invention proposes a system whereby it is possible to provide a tank already installed, underground type, for the storage of certain liquid products, such as those derived from oil, built with single wall, double wall for turn it into an intrinsically safe tank, with the provision of an intermediate interstitial chamber made from a porous material, and by which it is possible to identify the eventual leaks of stored product that, where appropriate, could occur, with the particularity that the aforementioned camera interstitial consists of a layer between both walls obtained at from waste materials, such as materials rubber type elastomerics, either natural or synthetic.

El campo de aplicación de la invención se encuentra comprendido, obviamente, dentro del sector industrial dedicado a la fabricación de tanques de almacenamiento de productos líquidos, en particular tanques para líquidos derivados del petróleo.The scope of the invention is obviously, within the industrial sector Dedicated to the manufacture of product storage tanks liquids, in particular tanks for liquids derived from Petroleum.

Antecedentes y sumario de la invenciónBackground and summary of the invention

Es conocido por todos en general, la utilización de tanques soterrados, utilizados para almacenar lo que se conoce en la práctica como "Productos Petrolíferos Líquidos, o PPLs", destinados a diversas aplicaciones. Muchos de estos tanques ya instalados responden al concepto de tanques de pared "simple", es decir, están construidos a base de una pared única de chapa de acero, de manera que, con el paso del tiempo, se ven afectados por agentes tales como la salinidad de las aguas, el efecto de la corrosión del suelo y las aguas, o incluso por las corrientes eléctricas parásitas, con lo que se produce un deterioro en la pared de los tanques que a continuación conduce, inevitablemente, a la aparición de fugas del producto almacenado, con las consiguientes filtraciones y contaminación de los suelos.It is known to everyone in general, the use of underground tanks, used to store what is known in practice as "Liquid Petroleum Products, or PPLs", intended for various applications. Many of these tanks already installed respond to the concept of "simple" wall tanks, that is, they are built based on a single wall of sheet metal steel, so that, over time, they are affected by agents such as water salinity, the effect of soil and water corrosion, or even by currents electrical parasites, resulting in deterioration in the tank wall that then inevitably leads to the appearance of leaks of the stored product, with the consequent leaks and contamination of the soils.

Para la solución del problema, se propusieron algunas medidas a principios de la década de los años 1990, en vista de que las leyes de protección medioambiental exigen que los tanques se construyan con una doble pared, de manera que en caso de rotura o perforación de alguna de ellas, la otra evite que se produzca la fuga del producto contenido, desarrollándose así el concepto de tanques "intrínsecamente seguros".For the solution of the problem, they proposed some measures in the early 1990s, in view that environmental protection laws require that tanks are built with a double wall, so that in case of breakage or perforation of one of them, the other prevents it produce the leakage of the contained product, thus developing the concept of "intrinsically safe" tanks.

El control exigido por las distintas administraciones, ha puesto de manifiesto la necesidad de buscar soluciones efectivas para los tanques que ya están instalados desde hace más tiempo, y cuya sustitución por otros nuevos resulta realmente inviable debido a problemas de altos costes económicos, y a otras circunstancias que en muchas ocasiones hacen que una sustitución de los mismos no resulte posible.The control required by the different administrations, has revealed the need to seek effective solutions for tanks that are already installed from longer, and whose replacement with new ones is really unfeasible due to problems of high economic costs, and to other circumstances that in many occasions make a replacing them is not possible.

Por todo ello, se conocen ya algunos intentos de solucionar los problemas planteados, y en este sentido se han propuesto alternativas tales como la contenida en el documento ES-2 066 610, titulado "Elemento de construcción compuesto de un tejido distanciador resinificado para formar un cuerpo hueco", cuya propuesta consiste en aplicar en el interior de un tanque de pared simple, tejidos de tipo resinificados, muy específicos, mediante los que se crea una zona intersticial con cavidades por las que se pueden detectar las fugas que puedan producirse entre la pared interior y la exterior.For all these reasons, some attempts to  solve the problems raised, and in this regard they have proposed alternatives such as the one contained in the document ES-2 066 610, entitled "Building Element composed of a resinized distance fabric to form a hollow body ", whose proposal is to apply inside of a single wall tank, resized type fabrics, very specific, through which an interstitial zone is created with cavities through which leaks that can be detected can be detected occur between the inner and outer wall.

También se conoce un sistema de fabricación suiza, comercialmente ofrecido bajo la denominación "DOPA", y que consiste en la realización de un revestimiento interior con una chapa de aluminio conformada a modo de botones, y la posterior realización de una pared interior en el tanque. Existen otros documentos basados en la formación de láminas especiales con la utilización de varios componentes.A manufacturing system is also known. Switzerland, commercially offered under the name "DOPA", and which consists in the realization of an inner lining with an aluminum sheet shaped like buttons, and the back realization of an inner wall in the tank. There are others documents based on the formation of special sheets with the use of several components.

Sin embargo, hasta ahora, ninguna de las alternativas propuestas ha logrado ofrecer una solución que resulte realmente eficaz para el problema planteado, ya que todas ellas adolecen de inconvenientes relacionados con dificultades constructivas o, en su caso, con costes de fabricación elevados que las hacen difíciles de aplicar.However, so far, none of the proposed alternatives has managed to offer a solution that results  really effective for the problem posed, since all of them suffer from difficulties related to difficulties construction or, where appropriate, with high manufacturing costs that They make them difficult to apply.

La presente invención se ha propuesto como objetivo principal el hecho de diseñar un sistema mediante el que resulte posible aportar soluciones prácticas eficaces y atractivas para los problemas asociados a la provisión de una doble pared interior a los tanques de pared simple, ya instalados, destinados al almacenamiento de productos tales como los productos petrolíferos líquidos, con el fin de hacer que los mismos puedan ser conceptuados como tanques intrínsecamente seguros. Este objetivo ha sido plenamente alcanzado mediante el sistema que va a ser objeto de descripción en lo que sigue, cuyas características principales se encuentran recogidas en la parte caracterizadora de la reivindicación 1 que sigue, y de las sub-reivindicaciones que la complementan.The present invention has been proposed as main objective is to design a system through which it is possible to provide effective and attractive practical solutions for the problems associated with the provision of a double wall interior to single wall tanks, already installed, intended to the storage of products such as products liquid oil, in order to make them can be conceptualized as intrinsically safe tanks. This objective has been fully achieved through the system that will be described below, whose characteristics main are collected in the characterizing part of claim 1 below, and of the sub-claims that complement it.

En esencia, el sistema propuesto por la invención consiste básicamente en la formación de una cámara intersticial aplicada a la totalidad superficial de la cara interna de la pared simple de acero de que consta el tanque, proporcionada mediante una capa de espesor predeterminado de material poroso obtenido a partir de residuos elastoméricos troceados y vinculados entre sí por medio de un material adherente adecuado. A continuación, una vez obtenida la mencionada capa intersticial, se proporciona una pared de plástico reforzado, tipo Resina Epoxi o de Poliéster reforzadas con Fibra de Vidrio interna, constitutiva de la doble pared, aplicada contra la propia capa elastomérica, quedando así formada e intercalada la mencionada cámara intersticial, y resultando especialmente eficaz para la detección de cualquier fuga eventual de producto almacenado que pudiera llegar a producirse.In essence, the system proposed by the invention basically consists of the formation of a chamber interstitial applied to the entire surface of the inner face of the simple steel wall consisting of the tank, provided by a layer of predetermined thickness of porous material obtained from chopped and linked elastomeric waste each other by means of a suitable adherent material. TO then, once the aforementioned interstitial layer is obtained, provides a reinforced plastic wall, type Epoxy Resin or Polyester reinforced with internal Fiberglass, constitutive of the double wall, applied against the elastomeric layer itself, the aforementioned chamber being formed and interspersed interstitial, and proving especially effective for detection of any eventual leakage of stored product that could get to occur.

Como se comprenderá, la invención proporciona la particularidad esencial de un reaprovechamiento de materiales que intrínsecamente constituyen materiales de desecho, junto con la característica también esencial de que una cámara intersticial construida a base de este tipo de materiales, presenta una naturaleza sumamente elástica que en una aplicación como la comentada, proporciona la ventaja de servir como medio amortiguador, evitando con ello que los fenómenos de contracción/dilatación de la pared externa (de acero), sean transferidos a la pared interior.As will be understood, the invention provides the  essential particularity of a reuse of materials that intrinsically constitute waste materials, along with the also essential feature of an interstitial chamber Built on this type of materials, it presents a extremely elastic nature than in an application such as commented, provides the advantage of serving as a means shock absorber, thereby preventing the phenomena of contraction / expansion of the outer wall (steel), whether transferred to the inner wall.

Tal y como se ha indicado en lo que antecede, la descripción detallada de la forma de realización preferida de la invención va a ser llevada a cabo con la ayuda de los dibujos anexos, a través de los cuales se utilizan las mismas referencias numéricas para designar las partes iguales o semejantes. Así, atendiendo en primer lugar a la Figura 1, se puede apreciar la representación esquematizada en planta superior, de un tanque 1 que contiene un producto líquido 7, de forma general cilíndrica como suele ser habitual en este tipo de depósitos, rematado mediante casquetes esféricos extremos, y dotado de una boca 2 de llenado, cerrada también de manera convencional. Según lo habitual, el tanque está soterrado, es decir, por debajo del nivel del suelo sobre un lecho 3 preparado al efecto en el interior de un alojamiento 4 de obra, a cuyo interior se accede a través de un conducto 5 realizado asimismo de obra.As indicated above, the  detailed description of the preferred embodiment of the invention is going to be carried out with the help of the drawings annexes, through which the same references are used numerical to designate the same or similar parts. So, attending first to Figure 1, you can see the schematic representation on the upper floor of a tank 1 that It contains a liquid product 7, generally cylindrical as It is usually common in these types of deposits, topped off by extreme spherical caps, and equipped with a filling mouth 2, also closed conventionally.

La sección longitudinal B-B' de la Figura 2 y la sección transversal A-A' de la Figura 3, muestran que la pared del tanque 1 es doble, es decir, existe una pared exterior la de acero, correspondiente con la pared original del tanque 1, y una pared interior 1b formada según el sistema de la invención, dejando entre ambas la cámara intersticial 6 a la que se ha aludido anteriormente, desarrollada como se explica con mayor detalle en lo que sigue. Esta disposición puede ser mejor apreciada en el detalle D que aparece representado, a mayor tamaño en la Figura 4.The longitudinal section B-B 'of Figure 2 and cross section A-A 'of the Figure 3, show that the wall of tank 1 is double, that is, there is an outer wall of steel, corresponding to the wall original of tank 1, and an inner wall 1b formed according to the system of the invention, leaving the interstitial chamber between them 6 referred to above, developed as Explain in more detail in what follows. This provision may be better appreciated in detail D that appears represented, to larger in Figure 4.

De este modo, la capa intermedia 6 proporciona una separación positiva entre ambas paredes del tanque 1, y constituye un medio eficaz para la detección de cualquier fuga eventual del producto líquido 7 contenido en dicho tanque, a la vez que permite que pueda circular el aire en cualquiera de las condiciones de trabajo del tanque.Thus, intermediate layer 6 provides a positive separation between both walls of tank 1, and It constitutes an effective means for the detection of any leakage possibly of the liquid product 7 contained in said tank, at the same time which allows air to circulate in any of the working conditions of the tank.

Tal y como se ha indicado en lo que antecede, la capa intersticial 6 ha sido obtenida, de acuerdo con la invención, a partir de residuos elastoméricos muy abundantes en el mercado.
