Resumen
El crecimiento de los grandes centros urbanos y el desarrollo tecnológico de la sociedad generan la creciente necesidad de aprovechar los terrenos. Esto lleva a utilizar, cada vez con más frecuencia, los espacios subterráneos y a aumentar las profundidades de las excavaciones para edificar.
Este estudio se abocará a presentar el sistema de anclajes inyectados, para la construcción de excavaciones de gran profundidad y completamente verticales, lo que permite el máximo aprovechamiento de los terrenos disponibles.
Este método se basa en que los anclajes inyectados son capaces de trasmitir las cargas de tracción al terreno, los anclajes están constituidos fundamentalmente por tubos, barras o cables de acero, introducidos en el suelo mediante una perforación y adheridos al terreno con lechada de cemento.
Existen en el mercado distintos tipos de anclajes, que, dependiendo de las necesidades, las solicitaciones y la metodología serán seleccionados para la ejecución de la obra. Este documento describe y revisa la tecnología existente en el mercado de los anclajes necesarios para la ejecución de las obras de sostenimiento de excavaciones subterráneas.
Los anclajes inyectados postensados tienen varias aplicaciones debido a su capacidad de resistir cargas y son usados tanto en obras mineras, viales, portuarias y civiles entre otras.
The growth of big urban centers and the development of technology in our society have generated a growing need to maximize the use of terrain. This carries us to use, each time with more frequency, the subterranean spaces and to enlarge the depths of the excavations in our buildings. This study will present the system of injected anchorages, for the construction of excavations of great depth and that are completely vertical, what allows us to use the maximum of the available lands. This method is based on the fact that injected anchorages are capable of transmitting the loads of traction to the land, the anchorages are constituted fundamentally by pipes, bars or cables of steel, introduced in the floor by means of a drilling and adhered at the land with whitewash of cement. In the market we can find different types of anchorages, depending on the requirements, the request and the methodology will be selected for the execution of the work. This document describes and revises the existing technology in the market of the anchorages, necessary for the execution of the works of maintenance of subterranean excavations. The injected anchorages after being tensed have several applications due to its capacity to resist loads and they are used in civil, harbor, road, and mining works among others
