Abstract (en)
[origin: EP1081331A1] The method involves setting up an acquisition flow in or below an upper region, especially on upper third, of a tunnel's cross-section, parallel and/or transverse to the tunnel's longitudinal axis to ensure uniform acquisition over the length of the acquisition flow, especially a turbulent flow. Air is sucked out radially or tangentially and fed to an outlet air channel (11) in the roof (12) of the tunnel (10). An Independent claim is also included for a suction system for a tunnel, especially a motorway or railway tunnel.
