摘要

The present invention relates to a kind of installation fire-fighting tunnels, especially in vcehicular tunnel (1). The equipment includes that nozzle duct (4) extends in parallel, along back (2), it is divided into vertical section (3), and is connected to nozzle (5,6), it is spraying to be formed, or receive this nozzle (5,6). Said nozzle pipeline is separately connected, part, and by valve (7), is used for extinguishing fluid to pressure line (8). The equipment further includes control device (10), pressure line (8) and said nozzle conduit (4) between the valve (7), the control device is connected to equipment (11), for positioning the fire in the source. In order to generate advantageous fire extinguishing condition, pilot jet (6) is provided except main burner (5) are carried out towards the tunnel (1) floor, and the pilot jet has less than main jet pipe (5) and the top tunnel for manufacturing spray in (5) of spray region (19) main jet pipe.
