Ring blower fan near point occurs for fire, and ring blower fan is by smog and toxic gas through transversal ventilation road dispatch to longitudinal ventilation
Bag, the longitudinal ventilation bag under empty flat state expands rapidly after smog and toxic gas are discharged into, will with maximum smoke evacuation ability
Smog and toxic gas dispatch go out outside Tunnel, are that the escape of staff in tunnel is raced against time, and improve the possibility of personnel escape
With the security of rescue.The utility model, without manually alarming, can carry out automatic alarm and accurate after fire in tunnel generation
The fire location in tunnel is really determined, detailed fire location coordinate is provided to rescue personnel.The utility model makes simple,
Cost is small, and low cost, early investment is small, and operation cost is low, and the smoke evacuation system of automatic independence, nothing are capable of after fire occurs
Need to manually it operate.The utility model changes traditional fire smoke evacuation thinking, and smog and toxic gas are utilized into single air channel
From the discharge of tunnel mid-section, the normal ventilation equipment in tunnel will not be impacted, improve ventilation when fire occurs
Efficiency.
Further, the utility model longitudinal ventilation bag is arranged in the cable trough under maintaining roadway, its air inlet and transverse direction
Ventilating duct is connected, and air outlet is extended to outside tunnel, takes full advantage of the clearance spaces in idle cable trough.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1-4, the distributed fiber grating temperature that the utility model includes being longitudinally arranged along tunnel in structure is passed
Sensor 3, is arranged in Smoke Sensor 2 of the tunnel body 1 at the position of vault 1/3rd, and sender unit 4 is arranged on
At tunnel portal position, connection distributed fiber grating temperature sensor 3 and each Smoke Sensor 2, sender unit 4 with
Alarm 5 in the outer control room of hole is connected, and sender unit 4 controls the ring blower fan 6 of each section.Secondary lining in tunnel
When building 10 construction, the circumferential groove opened up along tunnel cross-section direction is reserved at a certain distance, it is recessed that ring blower fan 6 is arranged on ring
