Description

PERFECCIONAMIENTOS EN EDÓMETROS PARA APLICACIÓN DE CARGAS PERFECTION IN EDOMETERS FOR LOAD APPLICATION
EN CÉLULAS EDOMÉTRICAS OBJETO DE LA INVENCIÓNIN EDOMETRIC CELLS OBJECT OF THE INVENTION
La presente invención, según se expresa en el enunciado de esta memoria descriptiva, se refiere a unos perfeccionamientos en edómetros para aplicación de cargas en células edométricas . El edómetro tiene en principio la finalidad de medir el grado de compresión unidimensional de un suelo, basándose los perfeccionamientos de la invención en unos medios de adaptación del edómetro para poder aplicar cargas en células edométricas de hasta 210 mm de diámetro con o sin control de la succión.The present invention, as expressed in the statement of this specification, refers to improvements in edometers for application of loads in oedometric cells. The Oedometer has in principle the purpose of measuring the degree of one-dimensional compression of a soil, based on the improvements of the invention in means of adaptation of the Oedometer to be able to apply loads in oedometric cells up to 210 mm in diameter with or without control of the suction.
La aplicación de la invención se enmarca dentro de las series científicas de la ingeniería del terreno y la ingeniería mecánica.The application of the invention is part of the scientific series of field engineering and mechanical engineering.
Más concretamente los sectores de actividad y tecnológicos en los que serían de aplicación la invención serían los campos de la mecánica del suelo, presas, terraplenes de carreteras, cimentaciones y también los aparatos científicos.More specifically, the activity and technology sectors in which the invention would be applicable would be the fields of soil mechanics, dams, road embankments, foundations and also scientific devices.
Estos campos de actividades son propios de la investigación, la ingeniería civil y geotécnica, la geología y la arquitectura.These fields of activities are typical of research, civil and geotechnical engineering, geology and architecture.
ANTECEDENTES DE LA INVENCIÓN El edómetro convencional, como elemento habitual en un laboratorio de mecánica del suelo, está diseñado para células edométricas de hasta 150 mm de diámetro, con alturas máximas de 90 mm.BACKGROUND OF THE INVENTION The conventional edometer, as usual element in a soil mechanics laboratory, is designed for oedometric cells up to 150 mm in diameter, with maximum heights of 90 mm.
Este tipo de edómetro, en su configuración convencional, no es viable actualmente para su uso con las nuevas células edométricas que están apareciendo en el mercado conforme avanzan las investigaciones en mecánica del suelo parcialmente saturado. Estas nuevas células, debido al control de la succión que llevan incorporado y a los requerimientos mecánicos que este control les impone, necesitan ampliar su tamaño hasta un valor del orden del doble de su valor convencional, tanto en diámetro como en altura.This type of oedometer, in its conventional configuration, is currently not viable for use with the new oedometric cells that are appearing on the market as mechanical research advances of partially saturated soil. These new cells, due to the control of the suction that they have incorporated and to the mechanical requirements that this control imposes on them, need to expand their size to a value of the order of double their conventional value, both in diameter and in height.
Actualmente, la posibilidad de uso de estas células edométricas en los ensayos de laboratorio convencionales pasa por su colocación en bancadas edométricas de gran tamaño que no son habituales en la mecánica del suelo, ya que, además de su elevado coste, generan problemas para su instalación debido a que requieren un gran espacio dentro de un laboratorio, pasando a desecharse los edómetros comunes . DESCRIPCIÓN DE LA INVENCIÓNCurrently, the possibility of using these oedometric cells in conventional laboratory tests is due to their placement in large orthometric benches that are not common in soil mechanics, since, in addition to their high cost, they generate problems for their installation because they require a large space inside a laboratory, the common edometers being discarded. DESCRIPTION OF THE INVENTION
Con el fin de alcanzar los objetivos y evitar los inconvenientes mencionados en los apartados anteriores, la invención propone unos perfeccionamientos en edómetros para aplicación de cargas en células edométricas de hasta 210 mm de diámetro con o sin control de la succión.In order to achieve the objectives and avoid the drawbacks mentioned in the previous sections, the invention proposes improvements in edometers for application of loads in oedometric cells up to 210 mm in diameter with or without suction control.
Los perfeccionamientos de la invención comprenden dos partes bien diferenciadas con unas características estructuras con respecto a los antecedentes existentes en su campo de aplicación. Una primera parte consiste en un nuevo marco de aplicación de carga, el cual se compone de dos vastagos laterales y un travesano en el que se coloca un tornillo de regulación que permite el ajuste entre el sistema de aplicación de carga y la célula edométrica. Este marco se acopla al cuerpo de un edómetro, permitiéndose de esta forma un acople perfecto que se realiza por procedimiento de atornillado u otro sistema adecuado. Una segunda parte consistente en un marco de reacción, compuesto por un dintel con altura regulable en función del tamaño del transductor de carga usado y dos soportes atornillados en sus bases a través de las correspondientes placas de anclaje y tornillos, siendo viable su instalación en cualquier tipo de superficie.The improvements of the invention comprise two well-differentiated parts with characteristic structures with respect to the background in their field of application. A first part consists of a new load application frame, which is composed of two lateral rods and a crossbar in which a regulating screw is placed that allows adjustment between the load application system and the oedometric cell. This frame is coupled to the body of an oedometer, thus allowing a perfect coupling that is made by screwing procedure or other suitable system. A second part consisting of a reaction frame, consisting of a lintel with adjustable height depending on the size of the load transducer used and two supports screwed into their bases through the corresponding anchor plates and screws, being feasible for installation in any type of surface.
El transductor de carga queda anclado así al dintel del marco de reacción a través de un tornillo que realiza la función de prisionero. Tanto el marco de aplicación de carga como el marco de reacción se han concebido con uniones atornilladas que permiten su fácil montaje y desmontaje, facilitando el cambio de configuración del edómetro convencional tanto para células de tamaños habituales como para células de gran diámetro.The load transducer is thus anchored to the lintel of the reaction frame through a screw that performs the function of prisoner. Both the load application frame and the reaction frame have been conceived with bolted joints that allow easy assembly and disassembly, facilitating the change of the conventional edometer configuration for both cells of usual sizes and for large diameter cells.
