Abstract
El propósito de este documento es desarrollar una aplicación de un sistema de sensorización y monitorización continua de la calidad del aire en las construcciones bajo el suelo que irá ubicada en la diana de la cabeza perforadora de una tuneladora en escudo abierto en una excavación con hinca de tubo; así como, indicar los factores y consideraciones que se han tenido en cuenta para realizar la selección de los sensores más adecuados para ésta aplicación, ofrecer una explicación de los principios en que se basan y de la instrumentación necesaria para una protección satisfactoria del personal y del medio ambiente. Este trabajo incluye el desarrollo teórico práctico de un dispositivo de protección para las excavaciones que no existe en la actualidad. Para ello se ha definido un sistema de alertas capaz de detectar de forma temprana y eficiente concentraciones nocivas de gases para los trabajadores de las rozadoras, estando dotado del sistema de comunicación necesario para tomar las medidas oportunas en caso de contaminación del aire. _______________________________________________________________________________________________________________________
The purpose of this document is to explain the development of an application of a sensing system and continuous monitoring of air quality in buildings under the ground will be located in the target of the drill head of a shield tunneling in an open excavation pipe jacking, as well as indicate the factors and considerations taken into account for selecting the most appropriate sensors for this application, provide an explanation of the underlying principles and instrumentation necessary for adequate protection staff and the environment. This work includes the theoretic practical development of a protective device for the excavations that does not exist at the present time.This defined an early warning system to detect early and effectively to harmful concentrations of gas workers in the coal cutters, being endowed with the necessary communication system to take appropriate measures in case of air pollution.
