摘要

The installation has a group of pipe-lines (1) disposed on an inner circumference of a tunnel (T) and of medium circulation zones, where openings are generated by the fire in a section of the pipe-lines. The pipe-lines are connected to a fluid distribution unit (4) and a group of smoke extractors (2). Detectors (5) are coupled to the extractors to detect a high temperature and the presence of smokes, where actuated power of each of the extractors depends on a location of an accident zone.
