摘要
The present invention provides a ssanggul tunnel, smoke and fire so as to prevent the phenomenon of fire smoke emanating from the fire tunnel in an emergency situation such as a fire at one of ssanggul tunnel of railway and road tunnel inlet to flow back to the other side of the tunnel It relates to a spindle structure for a non-return of the smoke.; The invention of sanghaengseon tunnel and hahaengseon tunnel according to ssanggul tunnel established at predetermined intervals separating at least a tunnel effective yirumyeonseo an equal height and the tunnel height diameter and at least equal to or more partition walls the upper and the hahaengseon tunnel having a length is flush with the tunnel moving direction between the extended shaft hayeoseo the outer tunnel, and provides sanghaengseon tunnels and technical configuration, it characterized in that the shaft so as to be separated by a space in front of the partition wall hahaengseon tunnel.; According to the present invention can achieve the normal ssanggul independent air control and fire behavior appears fire smoke inlet non-return effect of the tunnel to another, the conventional shaft protruding ssanggul prevent a back flow of smoke superior to the tunneling effect of the tunnel.
