Description
OBJETO DE LA INVENCiÓN OBJECT OF THE INVENTION
La presente invención se refiere a un dispositivo especialmente concebido para ser utilizado en canales, depósitos y otros recipientes de líquidos, cuya solera, o en ocasiones la totalidad de su sección, queda situada por debajo de la cota de aguas freáticas, es decir que la obra queda sumergida, total o parcialmente, en una masa de terreno saturada de agua, con lo que la obra recibe un empuje de flotación que afecta a su estática. The present invention relates to a device specially designed to be used in canals, reservoirs and other containers of liquids, whose solera, or sometimes the whole of its section, is located below the level of groundwater, that is to say The work is submerged, totally or partially, in a land mass saturated with water, so that the work receives a buoyancy thrust that affects its static.
El objeto de la invención es conseguir un dispositivo que, de forma automática, reduzca sustancialmente el citado empuje de flotación mediante evacuación del agua acumulada en la masa de suelo sobre la que se encuentra implantada la obra. The object of the invention is to achieve a device that, automatically, substantially reduces the aforementioned buoyancy thrust by evacuating the water accumulated in the mass of soil on which the work is implanted.
La invención se sitúa pues en el ámbito de la instalación de canales, conducciones subterráneas y depósitos enterrados, sometidos al empuje producido por las aguas freáticas. The invention thus falls within the scope of the installation of canals, underground conduits and buried deposits, subjected to the thrust produced by groundwater.
ANTECEDENTES DE LA INVENCiÓN BACKGROUND OF THE INVENTION
La solución inherente al problema apuntado en el apartado anterior, consiste en dotar a las capas inferiores de la obra de drenajes que permitan la evacuación del agua existente en el terreno, ya sea proveniente de lluvias o filtraciones de cauces próximos, por filtraciones de agua provenientes de la propia obra o por otra causa, con lo que lógicamente se reduce o elimina el empuje de flotación sobre dicha obra. The solution inherent to the problem pointed out in the previous section is to provide the lower layers of the drainage work that allow the evacuation of the existing water in the land, either from rains or leaks of nearby channels, by water leaks coming of the work itself or for another cause, which logically reduces or eliminates the buoyancy thrust on said work.
En la mayoría de las ocasiones no existe posibilidad física de dar un desagüe natural a los niveles a cota inferior a la solera del canal u obra de que se trate, por lo que se ha recurrido a crear desagües artificiales mediante estaciones de bombeo automático con determinados puntos, para evitar la saturación de capacidad del dreno In most cases there is no physical possibility of giving a natural drain to the levels below the floor of the canal or work in question, so it has resorted to creating artificial drains through automatic pumping stations with certain points, to avoid saturation of drain capacity
Concretamente son conocidos dispositivos de drenaje que incorporan válvulas anti-retorno, como por ejemplo válvulas de bola, que abren la comunicación en el sentido exterior-interior de la obra cuando la diferencia de presiones entre ambas caras de los paramentos superan valores que se estiman peligrosos para los mismos, pero sin embargo estos dispositivos están lejos de constituir una solución óptima. Specifically, drainage devices are known that incorporate non-return valves, such as ball valves, which open communication in the exterior-interior direction of the work when the pressure difference between both faces of the walls exceeds values that are considered dangerous for them, but nevertheless these devices are far from constituting an optimal solution.
De forma mas concreta tales dispositivos presentan una problemática que se centra fundamentalmente en los siguientes aspectos: More specifically, such devices present a problem that focuses primarily on the following aspects:
La apertura de la válvula anti-retorno se produce por la elevación de la esfera, lo que a su vez exige un empuje ascendente del agua freática sobre la misma, que retrasa la apertura y requiere de una diferencia entre los niveles de agua interior y exterior, que podría evitarse. En las fases finales del desagüe éste se produce a velocidades muy bajas, facilitando los depósitos de finos (limos, arcillas, e incluso arenas finas), en el interior del tubular de entrada. Estos depósitos, en el tiempo de inactividad del canal, a veces se endurecen y constituyen un entorpecimiento para el funcionamiento posterior de la válvu la. Estando sumergida la boca de salida del agua exterior, durante los periodos de servicio, queda expuesta a la posible formación de algas que, posteriormente, pueden dificultar el buen cierre de la esfera sobre su asiento. The opening of the non-return valve is caused by the elevation of the sphere, which in turn requires an upward thrust of the groundwater on it, which delays the opening and requires a difference between the levels of indoor and outdoor water , which could be avoided. In the final stages of the drain it is produced at very low speeds, facilitating deposits of fines (silts, clays, and even fine sands), inside the inlet tubular. These deposits, in the channel downtime, sometimes harden and constitute a hindrance to the subsequent operation of the valve. Being submerged the outlet of the outside water, during the periods of service, is exposed to the possible formation of algae that, later, can hinder the good closing of the sphere on its seat.

El dispositivo que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, en los diferentes aspectos comentados. The device that the invention proposes solves in a fully satisfactory manner the above-mentioned problem, in the different aspects mentioned.
Para ello y de forma mas concreta, el dispositivo que se preconiza centra sus características en el hecho de establecer comunicación directa y permanente entre el terreno sobre el que está implantada la canalización u obra de que se trate y el interior de dicha canalización, con la particularidad de que mientras su extremo inferior es fijo, el superior, donde se sitúa For this and more specifically, the device that is recommended focuses its characteristics on the fact of establishing direct and permanent communication between the land on which the canalization or work in question is implanted and the interior of said canalization, with the particularity that while its lower end is fixed, the upper one, where it is located

- la boca de salida del agua, se sitúa a su vez automática y permanentemente por encima del nivel de agua en tal canalización, con independencia de que, como es habitual, dicho nivel pueda oscilar entre cotas sustancialmente distintas determinadas por acusadas diferencias en el caudal que circula por la canalización. Específicamente el dispositivo se materializa en un tubo rematado, por el que debe ser su extremo inferior, en una tobera de conexión con el conducto o zanja de drenaje, determinando la correspondiente entrada de agua exterior a la obra, relacionándose el tubo propiamente dicho con la citada tobera a través de un manguito tubular flexible. Complementariamente en el que ha de ser el extremo superior de dicho tubo éste incorpora una boya-flotador que mantiene permanentemente la salida de agua por encima del nivel del líquido que circula por la canalización, con lo que se hacen innecesarias las clásicas válvulas anti-retorno, puesto que el líquido que circula por la canalización no puede nunca alcanzar la boca de salida que remata superiormente el dispositivo. the outlet of the water, is in turn automatically and permanently above the level of water in such channeling, regardless of the fact that, as usual, this level can range between substantially different levels determined by marked differences in the flow rate that circulates through the canalization. Specifically, the device is materialized in a capped tube, for which it must be its lower end, in a connection nozzle with the conduit or drainage ditch, determining the corresponding entrance of external water to the work, the tube itself being related to the said nozzle through a flexible tubular sleeve. In addition, in which the upper end of said tube has to be, it incorporates a float buoy that permanently maintains the water outlet above the level of the liquid that circulates through the pipeline, which makes the classic non-return valves unnecessary. , since the liquid that circulates through the pipeline can never reach the outlet that tops the device.
- Obviamente la inexistencia de válvula anti-retorno anteriormente expuesta y derivada de su propia presencia. Obviously the absence of a non-return valve previously exposed and derived from its own presence.
