Sector de la técnica Technical sector

La presente invención está relacionada con la formación de pozos de extracción de agua, proponiendo una estructura de pared de los pozos para esa función, con la cual se obtienen unas características muy ventajosas para la fabricación, el transporte y el montaje de instalación. Estado de la técnica The present invention is related to the formation of water extraction wells, proposing a wall structure of the wells for that function, with which very advantageous characteristics are obtained for the manufacture, transport and installation assembly. State of the art

La realización de pozos de extracción de agua se efectúa convencionalmente de dos formas diferentes, una de las cuales consiste en efectuar una perforación mediante una máquina que introduce directamente un elemento perforador en la tierra, colocando sucesivamente unos tubos de pared de la perforación, para contener la tierra, a medida que se va profundizando. Con este método el hueco de las perforaciones que se realizan es de muy poco diámetro, pero se pueden alcanzar grandes profundidades para llegar a las aguas subterráneas. The realization of water extraction wells is conventionally carried out in two different ways, one of which consists in drilling through a machine that directly introduces a drilling element into the ground, successively placing some perforation wall tubes, to contain the earth, as it deepens. With this method the hole of the perforations that are made is of very small diameter, but great depths can be reached to reach the underground waters.

Otra forma de realizar pozos es la excavación de un hueco en la tierra, hasta llegar a la aﬂoración del agua, colocándose a partir del fondo del hueco un apilamiento de anillos tubulares hasta rebasar la superﬁcie del suelo, para cubrir después con tierra el exterior del apilamiento de los anillos tubulares, de forma que por el interior del apilamiento de los anillos tubulares queda abierto un hueco que llega hasta el agua subterránea. Con este método la profundidad que se puede alcanzar es limitada, pero el hueco del pozo que se obtiene puede ser muy amplio. Another way of carrying out wells is the excavation of a hole in the earth, until it reaches the water flow, placing a stack of tubular rings from the bottom of the hole until it exceeds the surface of the soil, to later cover the exterior of the earth with soil. stacking the tubular rings, so that a hollow is opened through the interior of the stacking of the tubular rings that reaches the groundwater. With this method the depth that can be reached is limited, but the hole of the well that can be obtained can be very wide.

Los anillos tubulares que se utilizan en la práctica convencional, para los mencionados pozos de excavación, son anillos de hormigón armado y comprimido, los cuales se realizan en fábricas, desde donde se tienen que transportar hasta los lugares de realización de los pozos. The tubular rings that are used in conventional practice, for the mentioned excavation wells, are reinforced and compressed concrete rings, which are made in factories, from where they have to be transported to the locations of wells.

Dichos anillos de hormigón resultan de mucho peso, de forma que para su manipulación en las operaciones de carga y descargar respecto de los medios de transporte, así como para el montaje de instalación en los pozos de aplicación, tienen que ser manejados con grúas, lo cual encarece el costo global de la realización de los pozos. Además, dichos anillos ocupan un gran espacio, lo que hace también caro el transporte de los mismos, repercutiendo a su vez en el costo de los pozos para los que se destinan. Objeto de la invenciónThese concrete rings are very heavy, so that for their handling in loading and unloading operations with respect to the means of transport, as well as for the installation installation in the application wells, they have to be handled with cranes, which increases the overall cost of carrying out the wells. In addition, these rings occupy a large space, which also makes their transportation expensive, in turn affecting the cost of the wells for which they are intended. Object of the invention

De acuerdo con la invención se propone una estructura de pared para los pozos de agua que se realizan por excavación, la cual posee unas características de formación que determinan una funcionalidad ventajosa para la fabricación, el transporte y el montaje de instalación. In accordance with the invention, a wall structure is proposed for water wells that are made by excavation, which has formation characteristics that determine an advantageous functionality for manufacturing, transport and installation assembly.

Esta estructura objeto de la invención se compone de unas placas modulares ﬂexibles, de material plástico o similar, las cuales se unen entre sí por los extremos y por los laterales, formando una composición a modo de un mosaico, disponiéndose en las uniones unas tiras de cubrimiento, las cuales se ﬁjan a las placas coincidentes mediante tornillos, remaches o medios semejantes. This structure object of the invention is composed of flexible modular plates, of plastic or similar material, which are joined together by the ends and sides, forming a composition in the form of a mosaic, with strips arranged at the joints. covering, which are fixed to the matching plates by means of screws, rivets or similar means.

Las placas modulares ﬂexibles son de dos tipos, unas con la superﬁcie cerrada, y otras con una superﬁcie perforada, disponiéndose placas de superﬁcie cerrada en la zona del pozo que queda por encima del agua subterránea, mientras que en la zona inferior del pozo se disponen placas de superﬁcie perforada, para permitir la entrada del agua. The flexible modular plates are of two types, some with the surface closed, and others with a perforated surface, with surface plates closed in the area of the well above the groundwater, while in the lower area of the well are arranged perforated surface plates, to allow water to enter.

En dicha zona inferior que se forma con placas de superﬁcie perforada, la estructura se forma con dos paredes concéntricas, entre las cuales se disponen unas piezas separadoras, mediante las que se establece la unión de las placas componentes de las dos paredes concéntricas. De esta forma, en la parte inferior de la estructura, por la que tiene que entrar el agua al pozo, queda una pared hueca, en la cual se puede incluir un relleno de piedras para hacer de ﬁltro del agua que entra al pozo. In said lower zone which is formed with perforated surface plates, the structure is formed with two concentric walls, between which some separating pieces are arranged, by means of which the union of the component plates of the two concentric walls is established. In this way, in the lower part of the structure, through which the water has to enter the well, there is a hollow wall, in which a filling of stones can be included to de ﬁ lter the water entering the well.

Se obtiene así una estructura cuyos elementos componentes son de fácil y económica fabricación, pudiendo ser transportados los elementos componentes sueltos, desde el lugar de fabricación hasta los lugares de construcción de los pozos de aplicación, de modo que en los medios de transporte los elementos sueltos pueden ir apilados, resultando económico el transporte; para realizar el montaje de la estructura en los pozos de aplicación, por ejemplo formando anillos estructurales mediante unión de dos o más placas modulares, para luego ensamblar dichos anillos mediante montaje de superposición consecutiva de los mismos. A structure is thus obtained whose component elements are easy and economical to manufacture, the loose component elements can be transported, from the place of manufacture to the construction sites of the application wells, so that in the means of transport the loose elements they can be stacked, transport is economical; to assemble the structure in the application wells, for example forming structural rings by joining two or more modular plates, and then assembling said rings by mounting them consecutively.

La estructura objeto de la invención resulta por lo tanto ligera, económica y de fácil fabricación y transporte, adquiriendo por todo ello vida propia y carácter preferente, respecto de las estructuras convencionales, para la aplicación a la que está destinada. Descripción de las ﬁgurasThe structure object of the invention is therefore light, economical and easy to manufacture and transport, thereby acquiring its own life and preferential character, with respect to conventional structures, for the application to which it is intended.

Detailed description of the invention

El objeto de la invención se reﬁere a una estructura de pared para pozos de agua que se realizan por excavación, la cual se forma por composición de montaje en el lugar de aplicación, con elementos ligeros, económicos y fáciles de transportar. The object of the invention refers to a wall structure for water wells that are made by excavation, which is formed by mounting composition at the place of application, with light, economical and easy to transport elements.

La estructura preconizada se compone de placas modulares (1 y 2), las cuales se unen entre sí por los extremos y por los laterales, formando una composición a modo de un mosaico, disponiéndose en las uniones unas tiras (3) de cubrimiento de la unión, las cuales se ﬁjan sobre las placas coincidentes en la unión respectiva, mediante elementos (4) de cualquier tipo convencional, como tornillos, remaches, etc. The recommended structure is composed of modular plates (1 and 2), which are joined together by the ends and the sides, forming a composition in the form of a mosaic, with strips (3) covering the joints being arranged in the joints. union, which are fixed on the matching plates in the respective union, by means of elements (4) of any conventional type, such as screws, rivets, etc.

Las placas modulares (1 y 2) son ﬂexibles, de forma que con ellas se forman tramos tubulares para la composición de la estructura, formándose cada tramo tubular con una o más placas modulares (1 ó 2) en unión por sus extremos, mientras que la composición longitudinal de la estructura se forma acoplando en superposición los tramos tubulares que sean necesarios, entre los cuales se establece a su vez sujeción The modular plates (1 and 2) are flexible, so that with them tubular sections are formed for the composition of the structure, each tubular section being formed with one or more modular plates (1 or 2) in union at its ends, while the longitudinal composition of the structure is formed by overlapping the necessary tubular sections, among which clamping is also established

mediante unión de los bordes laterales de las placas modulares correspondientes. En la superposición de los tramos tubulares las placas modulares de los tramos modulares consecutivos pueden corresponderse alineadas, o bien en una disposición no coincidente, por ejemplo al tresbolillo, sin que ello altere el concepto de la invención. by joining the side edges of the corresponding modular plates. In the superposition of the tubular sections, the modular plates of the consecutive modular sections may correspond in alignment, or in a non-coincident arrangement, for example to the three-leg, without altering the concept of the invention.

Se han previsto placas modulares (1) de pared ciega y placas modulares (2) de pared perforada, de forma que en el montaje de aplicación de la estructura en los pozos de agua, la parte que queda por encima del nivel del agua se realiza con placas modulares (1) de pared ciega, mientras que la parte inferior se realiza con placas modulares (2) de pared perforada, para permitir la entrada del agua al pozo. Modular plates (1) of blind wall and modular plates (2) of perforated wall are provided, so that in the assembly of application of the structure in the water wells, the part that is above the water level is made with modular plates (1) of blind wall, while the lower part is made with modular plates (2) of perforated wall, to allow water to enter the well.

La parte inferior que se forma con placas modulares (2) de pared perforada, se determina además con dos paredes concéntricas, como se observa en las ﬁguras 2 y 4, entre las cuales se disponen unas piezas separadoras (5), tales como perﬁles de sección en “U” The lower part that is formed with modular perforated wall plates (2), is also determined with two concentric walls, as can be seen in Figures 2 and 4, between which some separating parts (5) are arranged, such as profiles of "U" section

o con conﬁguraciones equivalentes, de forma que dichas piezas separadoras (5) hacen de refuerzo y armazón entre las paredes concéntricas, ﬁjándose sobre ellas las placas modulares (2) de ambas paredes concéntricas. or with equivalent con ﬁ gurations, so that said separator pieces (5) act as reinforcement and framework between the concentric walls, the modular plates (2) of both concentric walls being fixed thereon.

Con esa formación, en dicha parte de la estructura formada con doble pared queda un hueco entre las paredes concéntricas, pudiendo incluirse en dicho hueco un relleno con piedras, para hacer de ﬁltro del agua que entra al pozo. With this formation, in said part of the structure formed with a double wall there is a gap between the concentric walls, and a filling with stones can be included in said hole, to de ﬁ lter the water entering the well.

Los elementos componentes de formación de la estructura se realizan de plástico u otros materiales ligeros y resistentes a la humedad y a los agentes corrosivos, lo cual permite una fabricación sencilla y económica de los elementos componentes, los cuales pueden ser apilados en conjuntos que ocupan muy poco espacio, para el almacenaje y el transporte, siendo dichos elementos, además, de fácil manejo para la carga y descarga respecto de los medios de transporte, así como para el montaje de la estructura en el lugar de aplicación, consiguiéndose con todo ello una reducción importante de costos globales para la realización de pozos agua, frente a la solución convencional de formación con anillos de hormigón. The component elements forming the structure are made of plastic or other light materials and resistant to moisture and corrosive agents, which allows a simple and economical manufacture of the component elements, which can be stacked in assemblies that occupy very little space, for storage and transport, said elements being, in addition, easy to handle for loading and unloading with respect to the means of transport, as well as for mounting the structure at the place of application, thereby achieving a reduction important of global costs for the realization of water wells, compared to the conventional solution of formation with concrete rings.

2. Statement motivated according to articles 29.6 and 29.7 of the Regulations for the execution of Law 11/1986, of March 20, on Patents on novelty and inventive activity; quotes and explanations in support of this statement

The object of the invention is a light structure for water wells. Understanding modular plates joined together, forming tubular sections; presenting the orifice plates when they are arranged below the water level, with concentric wall formed by these same plates with holes and annular space with spacers between them. The invention aims to reduce transport costs and facilitate assembly.

The request consists of 4 claims, the 1st of which is independent and the rest dependent.

The first claim includes the essential features of the invention. The second claim refers to the flexibility of the material from which they are constituted. The third claim relates to the arrangement of the plates below the water level. The 4th claim refers to the possible alignment or not of the mosaic.

Of the documents cited in the State of the Art Report, it is considered the closest to the invention, the WO2009137848 (DO1).

DO1 discloses a structure for water wells, capable of being made of light and flexible materials (See page 7, lines 5 to 8), of the type comprising overlapping tubular sections that form a retaining wall of the outer earth (See Fig. 3). Including interconnected modular plates, blind wall (62.1) and porous structure (102) (See page 8, lines 10-11); forming a mosaic structure, forming tubular sections by successive stacking. Arranging tubular sections formed with blind wall plates in the part of the structure that is above the water level; while at the bottom there are sections formed at least partially by plates of porous structure

The differences between DO1 and the 1st claim are:

-DO1 does not disclose that the joint between plates is by means of a strip of material fixed to the joint. However, the use of plate-screws for the purpose of joining adjacent elements is widely known in the State of the art. -DO1 discloses the use of "structurally porous" plates, not saying "perforated wall". However, they are equivalent terms for the purpose of functionality.

Claims 2 and 4 are disclosed in DO1.

Claim 3 is not disclosed in DO1.

Document DO2 discloses a structure for water wells (See Fig. 10, 11 and 12), where two structures are arranged coaxial tubular, both being bored below the water level. However, such structures are not They are formed by modular plates.

No document cited in the State of the Art Report, questions in an isolated or combined way the novelty and inventive activity of the 3rd claim.

Conclusion:

- Claims 1, 2 and 4 are new but lack inventive activity. (Art. 6 and 8 of Patent Law 11/1986). -The 3rd claim is new and has inventive activity. (Art. 6 and 8 of Patent Law 11/1986).
