The present disclosure provides a fire test system and method for tunnel structure based on real-time fusion of numerical and physical spaces. The fire test system includes: a physical test unit, to perform a holographic fire test on the typical segment components of tunnel structure system in a physical space, to obtain holographic characteristic parameter data of the typical components; a numerical analysis unit, to establish a full-scale numerical model of the tunnel-stratum composite system in a numerical space, to obtain multi-field coupling boundary data of the typical components; and a fusion control unit, to control and adjust a multi-field coupling boundary of the physical space according to the multi-field coupling boundary data, and to update and adjust an input parameter of the numerical space according to the holographic characteristic parameter data.

An unmanned vehicle for initiating a fire extinguishing action, the vehicle having: a vehicle sensor unit for detecting a fire parameter K.sub.F of a vehicle monitoring region, a vehicle communication unit for receiving an instruction signal S.sub.I representing a detected fire, a target location and/or a target region, and a navigation control unit for navigating the vehicle to the target location based on the instruction signal S.sub.I. The vehicle is: configured for detecting the fire parameter K.sub.F in the form of a verification fire parameter K.sub.V of the fire detector monitoring region at the target location by the vehicle sensor unit, configured for determining a verification fire status Z.sub.V by evaluating the verification fire parameter K.sub.V, and designed and/or configured for initiating a fire extinguishing action if the verification fire status Z.sub.V was determined. A system with such a vehicle and a corresponding method are also provided.

A fluid-jet emitting machine, particularly a firefighting machine, comprises a fluid-jet emitting device, a transport vehicle, lifting members and a control device.

Each lifting member comprises an actuator constrained to the transport vehicle and at least one idler wheel adapted to engage a rail of a track.

The actuators are configured to move the respective wheels between a non-operative position, in which the wheels are distanced from the respective rail, and an operative position, in which the wheels are arranged in contact with the respective rail.

The control device is operatively associated with the actuators to activate the passage of the wheels from the non-operative position to the operative position so that during movement along a track and in said operative position, the wheels prove to be pressed against the respective rail, exerting a force such as to reduce only part of the pressure exerted by the movement means of the vehicle on the track.

A control system for use during a tunnel fire includes: measurement means 100.sub.1 to 100.sub.n installed in each of a plurality of management sections assigned in a tunnel, and for measuring one or both of a gas concentration and a smoke concentration in the management section using a light signal; and control means 102 for identifying a management section which includes a fire point, and controlling blowing means 101 capable of changing an air volume, based on one or both of the gas concentration and the smoke concentration measured by one or more measurement means installed in one or more management sections located downstream of the identified management section.

A roadway conduit system includes a roadway conduit section that includes a floor portion with roadway surface configured to receive traveling vehicles, a ceiling portion, and at least one sidewall portion coupled to the floor portion and the ceiling portion such that the floor, ceiling, and at least one sidewall portions define a roadway conduit volume through which the traveling vehicles traverse the roadway conduit section. The roadway conduit section includes at least two fixedly connected preformed segments. The roadway conduit system also includes a roadway conduit ingress coupled to a first location of the roadway conduit section; a roadway conduit egress coupled to a second location of the roadway conduit section; and at least one air mover configured to circulate an airflow in the roadway conduit volume in a direction of at least one of the traveling vehicles.

An on-track work or rescue vehicle for fire-fighting and/or the rescue of persons in tunnels or subway tubes has a drive which can be operated for at least a limited duration without ambient air. A liquid tank is arranged on the work or rescue vehicle. A fan blower with a fluid spraying device is connected to the liquid tank for producing a spray mist. The work or rescue vehicle is a traction vehicle for pulling or pushing other rail vehicles. A work or rescue vehicle of this type can move to a fire source under the protection of the spray mist blown into the tunnel or subway tube and, if required, pull or push a damaged rail vehicle from a danger zone.
