Portuguese to English translations [PRO] Tech/Engineering - Construction / Civil Engineering / tunnel construction
Portuguese term or phrase:cambotas treliçadas
These are components used in the construction of tunnels. Cambotas seem to be tunnel arches (though please correct me on that if I'm wrong or there's a more specific term), but I can't find much info on what "treliçadas" might be.
"A TBM pilot tunnel was cut in the rock. It was used for drainage, geological reconnaissance and ventilation of the construction site. A TSM was used for widening of the roof section and face excavation; the rock was shored up with lattice arches, and steel-fibre-reinforced shotcrete was applied immediately behind the heading face." http://www.walo.ch/english/projekte/aktuelle-projekte/untert...
