| 摘要 |
The invention concerns a smoke extraction module (1), a smoke extraction system (20) and a method for using such a system which enables extracting of smoke (6) from tunnels, in particular large road tunnels. The module comprises a duct (2) for transportation of smoke, a suspension means (10) which is at least indirectly connected to the duct, thereby enabling suspended convection between the duct and the tunnel wall or tunnel ceiling (4) and a detachment mechanism (5), which, when activated, is arranged to detach the duct from the suspension means such that a displacement of the duct is enabled. |
