Roads and Rail Tunnels

Linear Heat Detection System

• Fiber optic linear heat detection systems have shown to be the most reliable method for monitoring road and rail tunnels safely and effectively.

• This technique for fire detection and prevention in tunnels is very dependable and affordable, with a range of up to 10 km per system.


Ventilation Control

• Absolute temperature values can be provided along the whole length of the asset using fibre   optic-based linear heat detection. This information can be included into the operator's ventilation control system, enabling them to use it both during regular operations and in the event of a fire.

Underground Power Cable Monitoring

Fiber optic DTS can be used as a linear heat detection device in addition to condition monitoring.


They are either mounted on the cables or at the tunnel's apex, and they offer advance notice of any potential hot spots in the electrical wires.

Applications


  • Tunnels – Road, Rail and metro.

  • Car parks.

  • Conveyor belts.

  • Aircraft hanger.

  • Cable trays and culvert.

  • Large industrial facilitie.

  • Tank farms.

  • Warehouses and freezers.

  • Escalators.

Applications of Linear Heat Detection


In order to monitor surroundings over a long distance (linear assets), usually in a unique hazard setting, fire detection devices are referred to as Linear Heat Detectors.

Anywhere along the length of the linear heat sensing cable, which can reach lengths of several kilometres, a fire can be detected by linear heat detection devices.

One of the primary technologies used in this area is distributed fibre optic temperature sensing.



The use of linear heat fire detection systems is advantageous in a wide range of industrial applications, including -


It is essential to have a reliable fire detection system for early detection in order to enable fire control and prevent loss of life because road and rail tunnels tend to have restrictive escape routes and ventilation :


  • Safety of tunnel users and owners.
  • To ensure continual availability of the tunnel.
  • To ensure trouble free operation.
  • Minimise maintenance work.

Motor vehicle collisions, tunnel-based material combustion (including debris and oil spills), and electrical problems are some of the things that start fires.

Field testing and fires have demonstrated that burning vehicles in tunnels heat up significantly more fast than would be predicted in a typical fire.


Smoke and gases flow in different ways depending on a number of variables, including :


  • The extent of the fire (fire load, intensity).
  • The ventilation system.
  • The natural air currents.
  • The smoke venting system.
  • The profile and pitch of the tunnel.

Cable trays and cable tunnels have been substantially protected using DTS technology.

These two apps in this setting are different from one another.

Notwithstanding the rarity of cable tunnel fires, these occurrences can have a substantial financial impact on the owner corporations due to the crucial business information and services that these important "arteries" may offer. If fires in these settings are not soon discovered, the owner companies' ability to protect their employees and their assets could be seriously jeopardised.

Significant amounts of hazardous smoke and gases may be produced by high intensity fires, making it difficult for trapped people to escape and for fire and rescue crews to reach the scene to put out the fire .
So, it is crucial.


The main fire risks associated with cable tunnel and cable trays are due to :

  • electrical cables with faults inside the cable trays.
  • Unreliable electrical machinery used to regulate the tunnel environment.
  • Related hot works that could be done on a regular basis.
  • accumulation of combustible materials that workers have discarded.


Advanced Fire Detection System

For easy access into and out of large, complicated structures, escalators are essential.

As a result, escalators can be a crucial component of an emergency escape plan for a structure.

The choice of whether to utilise an escalator to evacuate personnel from a building in an emergency situation is a difficult one, and there are many things to take into account before starting the process of considering the adoption of escalators for emergency evacuation.

This method may account for incidents other than fires, such as Imminent Catastrophic Events (ICE).
The safe operation of the escalators depends on the continuous availability of the emergency exits connected to them.


In light of the above, the main fire risks associated with escalators are due to :

  • the escalator's direction and movement are controlled by faulty electrical machinery.
  • The gradual breakdown of roller bearings may cause localised overheating.
  • The escalator may frequently be in close proximity to associated hot works that need to be done.
  • accumulating flammable goods that staff members have thrown away.


Underground Power Cable Monitoring

In belt type conveyors, moving and static fires, respectively, are the two main types of fires that need to be quickly identified.

Most frequently, infrared type equipment is used to detect moving fires along with CO2 detection occasionally, at predetermined strategic points along the conveyor system.

It is usual to use a linear heat detection system to detect both static flames and potentially big moving fires since this strategy by itself cannot offer detection coverage throughout the whole length of the belt.

The electrical drive machinery used to supply energy to the belt conveyor system might also catch on fire in close proximity to the belt.


The main fire risks associated with belt type conveyors are as follows :

  • Belt traction loss-related friction and slippage on the driving roller.
  • Hot molten material may result from welding operations.
  • Putting hot materials on the belt.
  • Creation of dust clouds and accumulation of objects that have fallen off the belt.
  • Static Electricity.
