SECTOR DE LA TÉCNICA AL QUE SE REFIERE LA INVENCIÓN:  SECTOR OF THE TECHNIQUE TO WHICH THE INVENTION REFERS:
La invención esta comprendida dentro del sector de la obra pública. ESTADO DE LA TÉCNICA  The invention is comprised within the public works sector. STATE OF THE TECHNIQUE
En la actualidad se están ejecutando túneles mediante los llamados métodos convencionales, esto es excavación y ejecución in situ del túnel, o mediante tuneladoras, máquinas que van excavando y a la vez colocando las dovelas o revestimiento interior de hormigón armado del túnel.  At present, tunnels are being executed by means of the so-called conventional methods, this is excavation and execution in situ of the tunnel, or by tunneling machines, machines that are excavating and at the same time placing the segments or interior cladding of reinforced concrete of the tunnel.
Este tipo de tareas, sobre todo en el caso de tuneladoras, tienen una aplicación interesante para grandes longitudes debido al elevado coste de la maquinaria requerida.  These types of tasks, especially in the case of TBMs, have an interesting application for large lengths due to the high cost of the required machinery.
Es por esto que se inventa una nueva forma de construir túneles, que no requiera inversiones tan altas y que sea mas eficaz y eficiente para la ejecución de estas obras con dimensiones moderadas, y que denominaremos túnel empujado mediante tramos sucesivos.  That is why a new way of building tunnels is invented, which does not require such high investments and is more efficient and efficient for the execution of these works with moderate dimensions, and which we will call a tunnel pushed through successive sections.
EXPLICACIÓN DE LA INVENCIÓN EXPLANATION OF THE INVENTION
La invención se basa en la ejecución de tramos de túnel, (piezas de hormigón armado con la forma apropiada para que una vez introducidos en el terreno, serán el revestimiento de hormigón de dicho túnel) en las inmediaciones de la zona definitiva, de manera que una vez construidos, mediante empuje oleodinámico, es decir con cilindros hidráulicos, con dimensiones de 200 x 350 x 500 (0 vástago x 0 pistón x carrera), que trabajarán con una fuerza de 250 t/cilindro y hasta una presión máxima de trabajo de 260 bar, maniobrados por un equipo eléctrico dotado de todos los componentes de seguridad necesarios, se trasladarán hasta su ubicación final hasta completar la longitud total. A medida que avanzamos se hace preciso, lógicamente, que con la maquinaria apropiada vayamos extrayendo las tierras o roca que se hayan en el espacio que va a ocupar el nuevo túnel. Para esto se construyen uno a continuación de otro, los tramos que se pueda dependiendo del espacio que en cada caso se disponga, con una separación entre ellos que permita la interposición de baterías de cilindros hidráulicos que serán los que empujen para la traslación de los mismos (ver Figura n° 4: TRAMOS Io, 2o Y 3o DE TUNEL. SECCIÓN LONGITUDINAL y Figura n° 5: TRAMOS Io, 2o Y 3o DE TUNEL. PLANTA). The invention is based on the execution of tunnel sections, (pieces of reinforced concrete with the appropriate shape so that once introduced into the ground, they will be the concrete lining of said tunnel) in the immediate vicinity of the final area, so that once built, by means of an oleodynamic thrust, that is to say with hydraulic cylinders, with dimensions of 200 x 350 x 500 (0 rod x 0 piston x stroke), which will work with a force of 250 t / cylinder and up to a maximum working pressure of 260 bar, operated by an electrical equipment equipped with all the necessary safety components, will be moved to their final location until the total length is completed. As we move forward it becomes necessary, logically, that with the appropriate machinery we will extract the earth or rock that is in the space that the new tunnel will occupy. For this purpose, the following sections are constructed, depending on the space that is available in each case, with a separation between them that allows the interposition of hydraulic cylinder batteries that will be the ones that push them to move them (See Figure 4: SECTIONS I o , 2 o Y 3 o OF TUNNEL. LONGITUDINAL SECTION and Figure n ° 5: SECTIONS I o , 2 o Y 3 o OF TUNNEL. PLANT).
Cuando se ha agotado todo el espacio disponible para construir tramos seguidos, y al lado del último, se ejecutará otro tramo paralelo a este, de tal manera que cuando los anteriores avancen, se desplace lateralmente hasta ocupar la posición que en su ubicación inicial ocupaba el ultimo construido de forma seguida, dejando sitio para ejecutar otro y así de forma sucesiva hasta que se realicen los necesarios para completar la longitud del túnel a (ver Figura n° 5: TRAMOS Io, 2o Y 3o DE TUNEL. PLANTA). When all the available space to build consecutive sections has been exhausted, and next to the last one, another section parallel to it will be executed, so that when the previous ones advance, it moves laterally until it occupies the position that in its initial location occupied the The last one was built in a row, leaving room to execute another and so on until the necessary ones are completed to complete the length of the tunnel a (see Figure 5: SECTIONS I o , 2 o Y 3 o DE TUNEL. PLANT) .
Como decimos, la invención se basa en la construcción de tramos de túnel, que se desplazarán sucesivamente mediante empuje con cilindros hidráulicos colocados entre ellos hasta llegar a la ejecución total de la obra, para lo que será necesario, disponer entre cada dos tramos, en la zona de los cilindros, de chapas ancladas al tramo que va delante y que deslizarán sobre el de detrás, en el momento del avance, que cierren este espacio e impidan desmoronamientos del terreno (ver Figura n° 7: TRAMOS Io, 2o Y 3o DE TÚNEL. PLANTA EN AVANCE). As we say, the invention is based on the construction of tunnel sections, which will be moved successively by means of thrust with hydraulic cylinders placed between them until reaching the total execution of the work, for which it will be necessary, to arrange between every two sections, in the area of the cylinders, of plates anchored to the section that goes ahead and that will slide over the one behind, at the time of the advance, that close this space and prevent landslides (see Figure 7: SECTIONS I or , 2 or and 3 or TUNNEL. PLANT IN ADVANCE).
Asimismo destacar que el vano primero se diferenciará del resto de los que posteriormente se trasladarán, en que la parte frontal del mismo no será recta, sino que tendrá una inclinación en sus hastíales o paredes para que a medida que se produzca la excavación, el derrame del terreno esté en consonancia con la forma de la estructura. Also note that the first vain will be different from the rest of those that will later be moved, in that the front part of it will not be straight, but will have an inclination in its gables or walls so that as the excavation occurs, the spill of the land is in line with the shape of the structure.
(ver Figura n° 1 : TRAMO Io DE TUNEL. SECCIÓN LONGITUDINAL y Figura n° 2: TRAMO Io DE TUNEL. PLANTA). (See Figure 1: SECTION I or TUNNEL. LONGITUDINAL SECTION and Figure 2: SECTION I or TUNNEL. PLANT).
A su vez y para controlar que los desplazamientos horizontales y verticales sean los deseados, el primer tramo estará rematado en el borde de la parte frontal con terminaciones adecuadas en acero (ver Figura n° 3: REMATES FRONTALES DE TRAMO Io DE TUNEL) Por otro lado, y para evitar que en la traslación, los cilindros hidráulicos puedan sufrir daños como consecuencia de la reacción transmitida por el empuje de los que inmediatamente le preceden, se colocarán entre tramos piezas con forma de cilindros metálicos con pared de 30 mm que absorban estos esfuerzos (ver Figura n° 8: TRAMO ÚLTIMO DE TÚNEL. PLANTA). In turn and to control that the horizontal and vertical displacements are the desired ones, the first section will be finished off in the edge of the front part with suitable steel endings (see Figure 3: FRONT SECTIONS OF SECTION I or TUNNEL) On the other hand, and to avoid that in the translation, the hydraulic cylinders can suffer damages as a result of the transmitted reaction due to the push of those who immediately precede it, pieces in the form of metal cylinders with a 30 mm wall that absorb these forces will be placed between sections (see Figure 8: LAST TUNNEL SECTION. PLANT).
Para empujar el ultimo de los tramos que se ha construido de forma seguida, así como los que se desplazarán lateralmente, se dispondrá, para absorber la reacción ejercida en el empuje de los mismos, de sendos muros de reacción de hormigón armado a los que se trasladarán los esfuerzos (ver Figura n° 4: TRAMOS Io, 2o Y 3o DE TUNEL. SECCIÓN LONGITUDINAL y Figura n° 5: TRAMOS Io, 2o Y 3o DE TUNEL. PLANTA) To push the last of the sections that have been built in a row, as well as those that will move laterally, it will be arranged, to absorb the reaction exerted in the thrust thereof, of two concrete reaction walls of reinforced concrete to which efforts will be taken (see Figure 4: TRAMOS I or 2 or 3 or TUNNEL aND longitudinal section and Figure 5. TRAMOS I or 2 or 3 or TUNNEL aND PLANT.)

MODO DE REALIZACIÓN La invención consiste en que para realizar túneles de dimensiones moderadas, se llevará a cabo mediante el empuje de sucesivos tramos de túnel que darán lugar a la obra final. MODE OF REALIZATION The invention is that to make tunnels of moderate dimensions, it will be carried out by pushing successive sections of tunnel that will lead to the final work.
El procedimiento de ejecución será como sigue: The execution procedure will be as follows:
Fase A Phase A
Ejecución del primer tramo de túnel sobre una solera de hormigón armado que servirá de apoyo y entre unos muretes guía que impedirán los desplazamientos transversales indeseados en el avance, en las inmediaciones de la ladera o montaña donde se va a ejecutar la obra, que será diferente, según se ha mencionado, al resto de los tramos (ver Figura n° 1 TRAMO Io DE TÚNEL. SECCIÓN LONGITUDINAL y Figura n° 2 TRAMO Io DE TÚNEL. PLANTA). Fase B Execution of the first section of tunnel over a reinforced concrete slab that will serve as support and between some guide walls that will prevent unwanted transverse displacements in the advance, in the immediate vicinity of the slope or mountain where the work will be executed, which will be different , as mentioned, to the rest of the sections (see Figure 1 SECTION I or TUNNEL. LONGITUDINAL SECTION and Figure 2 SECTION I or TUNNEL. PLANT). Phase B
Ejecución de los tramos de túnel seguidos al primero sobre solera de hormigón armado y entre muretes guía al igual que este, que la zona de trabajo permita, con una separación entre ellos para la interposición de una batería de cilindros hidráulicos que se encargará de transmitir los esfuerzos necesarios para el desplazamiento de los tramos (ver Figura n° 4 TRAMOS Io, 2o Y 3o DE TÚNEL. SECCIÓN LONGITUDINAL y Figura n° 5 TRAMOS Io, 2o Y 3o Execution of the tunnel sections followed by the first on reinforced concrete floor and between guide walls as well as this one, that the work area allows, with a separation between them for the interposition of a battery of hydraulic cylinders that will be responsible for transmitting the effort required for moving the sections (see Figure 4 RUNS I or 2 or 3 or Y TUNNEL. LONGITUDINAL SECTION and Figure 5 RUNS I or 2 or 3 or Y
DE TÚNEL. PLANTA). OF TUNNEL. PLANT).
Fase C C phase
Ejecución del muro de reacción detrás del último tramo, que permita absorber los esfuerzos transmitidos por la batería de cilindros hidráulicos de este último tramo (ver Figura n° 4 TRAMOS Io, 2o Y 3o DE TÚNEL. SECCIÓN LONGITUDINAL y Figura n° 5 TRAMOS Io, 2o Y 3o DE TÚNEL. PLANTA). Execution of the reaction wall behind the last section, which allows the forces transmitted by the battery of hydraulic cylinders of this last section to be absorbed (see Figure 4 SECTIONS I o , 2 or Y 3 or TUNNEL. LONGITUDINAL SECTION and Figure n ° 5 SECTIONS I o , 2 o Y 3 o TUNNEL. PLANT).
Fase D Phase D
Ejecución de un tramo de túnel paralelo al ultimo seguido con su muro de reacción correspondiente, en caso de ser necesario, para que una vez trasladados todos los anteriores que están enfrentados entre si, pueda desplazarse este lateralmente hasta ocupar el sitio del ultimo seguido, y así continuar empujando tramos (ver Figura n° 5 TRAMOS Io, 2o Y 3o DE TÚNEL. PLANTA). Fase E Execution of a tunnel section parallel to the last one followed with its corresponding reaction wall, if necessary, so that once all the previous ones that are facing each other have been moved, it can move laterally until it occupies the site of the last one followed, and thus continue pushing sections (see Figure n ° 5 SECTIONS I o , 2 o Y 3 o TUNNEL. PLANT). E phase
Colocación de las baterías de cilindros hidráulicos entre tramos y de las piezas cilindricas que aguantarán la reacción del empuje del tramo que le precede (ver Figura n° 4 TRAMOS Io, 2o Y 3o DE TÚNEL. SECCIÓN LONGITUDINAL, Figura n° 5 TRAMOS Io, 2o Y 3o DE TÚNEL. PLANTA y Figura n° 6 TRAMOS Io, 2o Y 3o DE TÚNEL. SECCIÓN LONGITUDINAL EN AVANCE). Inserting batteries hydraulic cylinders between sections and the cylindrical parts that will endure the reaction thrust portion preceding it (see Figure 4 RUNS I or 2 or Y 3 or TUNNEL. SECTION LONGITUDINAL, Fig.5 SECTIONS I o , 2 o Y 3 o TUNNEL PLANT and Figure n ° 6 SECTIONS I o , 2 o Y 3 o TUNNEL. LONGITUDINAL SECTION IN PROGRESS).
Fase F Phase F
Empuje del primer tamo de túnel el recorrido de los cilindros hidráulicos, recogerlos y empuje del que le sigue repitiendo la operación en todos los tramos seguidos.  Push the route of the hydraulic cylinders from the first tunnel tunnel, pick them up and push the one that continues to repeat the operation in all the sections in a row.
Fase G G phase
Interposición entre el último tramo y el muro de reacción construido detrás de este, de vigas fabricadas a tal efecto (ver Figura n° 0 8 TRAMO ÚLTIMO DE TÚNEL. PLANTA), que permitan cubrir el hueco que a medida que se avanza va quedando entre estos, y sirvan de apoyo de los cilindros para el avance. Esta operación se realizará hasta que este avance sea el suficiente para que quede hueco a fin de trasladar lateralmente el tramo paralelo al último y que previamente ya se había ejecutado, para lo que se retirarán estas vigas que habían ido colocando. Interposition between the last section and the reaction wall built behind it, of beams manufactured for this purpose (see Figure 0 8 LAST TUNNEL SECTION. PLANT), which allow to cover the gap that as it progresses between these, and serve as support of the cylinders for the advance. This operation will be carried out until this advance is sufficient so that it is hollow in order to laterally move the section parallel to the last one and which had previously been executed, for which these beams that had been placed will be removed.
Fase H H phase
Fabricar otro tramo en la zona que ha quedado libre al desplazar el tramo lateral hasta colocarlo alineado con los anteriores.  Make another section in the area that has been free when moving the side section until it is aligned with the previous ones.
Fase I Phase I
Repetir estas operaciones las veces que sean necesarias hasta cubrir con tramos la longitud de túnel que se necesite en cada caso.  Repeat these operations as many times as necessary to cover the length of tunnel needed in each case.
