December 2016. Gas and fire detection, and air quality control in road tunnel.
The La Aldea tunnel is a 3,145-meter long tunnel that will be the longest in the Canary Islands and will be among the 20 longest in Spain. The tunnel has two tubes, each one of them with an 11-meter platform including two lanes, two shoulders and two sidewalks.
The tunnel was built using drilling and blasting through complete section, with a sealing coat of sprayed concrete and supported with sprayed concrete reinforced with steel fiber. Another cladding coat made of sprayed concrete with polypropylene fiber is included for fire protection.
For the gas and fire detection systems in this state-of-the-art tunnel, products manufactured or distributed by DURÁN ELECTRÓNICA have been chosen. Air quality control is carried out with anemometers, opacimeters and luminance meters distributed by DURÁN ELECTRÓNICA.
