Description
Technical field
The utility model is related to long highway tunnel fire engineering field, and in particular to a kind of novel road tunnel is water base-
Foam integrated synthesis fire-fighting system.
Background technology
With the development of economic technology, people are continuously increased to the demand of traffic, and increasing vcehicular tunnel is built.
Vcehicular tunnel is compared with the tunnels such as railway, subway, and because of its fuel combustion vehicle that passes through, combustible is more, delivery vehicle more disordering, fire
Calamity probability is higher, at all can not there is the water such as trickling type fire, common fire hydrant means of fire especially caused by vehicle fuel
Effect is puted out a fire to save life and property, therefore long highway tunnel can typically set up aqueous film forming foam extinguishing device in addition to conventional hydrant system is set.Separately
It can typically be set up for Extra-long Highway Tunnel, underwater highway tunnel or traffic volume is big, fire hazard is big urban road tunnel outside
Foam-water spraying automatic fire extinguishing system.At present, such as region specification in Shanghai sets foam-water to spray certainly vcehicular tunnel
Dynamic fire extinguishing system has done related request.
Long highway tunnel is often sprayed with fire-fighting system by hydrant system, aqueous film forming foam extinguishing device and foam water at present
Mist automatic fire extinguishing system three parts form, and as shown in Fig. 5,6,7, interior conduit arrangement in tunnel is substantially into three independent pipe networks, bubble
Foam pipe network, the water supply network of foam water spray automatic fire extinguishing system, in addition also fire hydrant and aqueous film forming foam extinguishing device share
Water supply network；As shown in figure 9, this kind of system fire pump room need to set 1 set of foam pump group (containing 2 foam pumps, 1 vacuum tank
And 1 foam tank), 1 set of foam water spray automatic fire extinguishing system water supply pump group is (containing 2 fire pumps, 2 stabilized pressure pumps, 1 voltage stabilizing
Tank), 1 set of fire fighting supply pump group (containing 2 fire pumps, 2 stabilized pressure pumps, 1 vacuum tank)；As shown in figure 11, this kind of system uses
