In this case, while the compressed air is filled from the upper portion of the inner wall frame tube 30 on both sides and is filled downward, the shank means 60 has a long guide inlet in the case of the flexible inlet 62. As the 64 is extended, air must be passed with a stronger compressive force, so that the compressed air is first passed through the shank means 60 in the pillar frame tubes 20, 20 'and then the shank having a long guide inlet 64. Compressed air is passed through the means 60 so that the compressed air is injected into the upper portion of both inner wall frame tubes 30.

Therefore, the compressed air is injected into the upper portion of both inner wall frame tubes 30, and the compressed air is transferred to the ceiling frame tubes 30 'through the shank means 60 at the upper end of the pillar frame tubes 20 and 20'. As the third injection, the inner wall and the ceiling frame tubes 30 and 30 'are in a taut state, and thus, the bottom wall tube 10 and the pillar frame tubes 20 and 20' become a strong skeleton.

In this state, the compressed air is injected into the sealed tube 40 through the shank means 60 installed from the inner wall and the ceiling frame tubes 30 and 30 ', respectively.

Therefore, the sealed tube 40 is the inner wall and ceiling frame tube as shown in Figures 4 and 5 because the compressed air is injected into the fourth wall after the inner wall and ceiling frame tubes (30,30 ') are completely filled with compressed air. The space between 30 and 30 'and the tunnel inner wall Ta or tunnel ceiling Tb is blocked.

At this time, since the sealing tube 40 is made of a flexible material such as silicone rubber, it is elastic and completely closes to the tunnel inner wall Ta or the tunnel ceiling Tb to completely shield the tunnel T. It is possible to prevent the smoke generated at the point of fire (G) from leaking toward the entrance of the tunnel (T).

   Accordingly, as shown in FIG. 1, the air blower 80a is simultaneously operated while being shielded by the shielding mechanism 1 on both sides of the fire occurrence point G, and then causing a person to escape toward the escape door member 71. The smoke is discharged out of the tunnel (T) by the exhaust hose (80).

And by connecting the digestion gas cylinder (K) to the fire hose 81 is to put a digestion gas, such as carbon dioxide toward the fire occurrence point (G) to be more quickly extinguished.

Therefore, in the present invention, the space portions between the bottom frame tube 10 and the pillar frame tubes 20 and 20 'and the inner wall and the ceiling frame tubes 30 and 30' are shielded by the barrier member 50 and are produced in the compressor. Compressed air is injected through the inlet (2) and the first injection to the lower portion of the middle of the bottom frame tube (10) and pillar frame tubes (20,20 ') and the inner wall frame tube (30) and then the pillar frame tube (20). 20 ') the second injection into the upper portion and the third injection into the upper end of the ceiling frame tube (30') and both inner wall frame tube (30) and each to be sequentially injected to the fourth injection into the closed tube (40) A shielding mechanism (1) having a check means (60) is installed on both sides of the fire occurrence point (G) in the tunnel (T), respectively, so that the fire occurrence point (G) is sealed, and then to one side of the blocking film member (50). The smoke is discharged through the elongated ventilation hose 80 and the exhaust fan 80a provided, and the fire is blown through the fire hose 81. A tunnel fire extinguishing method using a tunnel shielding mechanism configured to extinguish a fire by injecting extinguishing gas into a living spot G is realized.

For example, when a fire occurs at a point close to an entrance of a tunnel T, a shield 1 is installed only at the entrance of the opposite tunnel T to prevent smoke from moving toward the middle of the tunnel T. By blocking it, it is possible to minimize the casualties caused by smoke suffocation in the tunnel.
