A split air cabin ventilation system for construction of tunnel inclined shafts, including a first air cabin and a second air cabin which are both in a hollow closed structure with an air inlet end and an air outlet end respectively at both sides. The two air outlet ends are arranged away from each other. An end of the split air cabin is provided with an air inlet, and the other end is provided with an air outlet. The air inlet is connected to an air source, and the air outlet is connected to the air inlet ends of the first and second air cabins, respectively. The air inlet end of the first air cabin is connected to another air source.

The present invention relates to a sealing system, its uses and method of use for forming a seal against a surface, and in particular for plugging and sealing an orifice such as a road or railway tunnel to prevent or minimise the dispersion of hazardous agent(s) in an emergency scenario. The system comprises a frame (200) which can be orientated against a surface (50) of an orifice, frame (10) comprising a perimeter outer surface (180) through which pliant elements (40) can extrude, via apertures (22), following the initiation of a means (30) for providing an overpressure.
