Ondergrondse spoorvervoer is 'n nuwe manier van vervoer wat padverkeerdruk verlig.
In brandveiligheid werk, the administrative and supervisory authorities have clear regulations on the installation of fire extinguishing systems and other fire extinguishing equipment.
Vir die keuse van 'n brand onderdrukking stelsel, met inagneming van die besonderhede van ondergrondse spoorvervoer, en omgewingsbeskerming te oorweeg, veiligheid, ekonomie, en brandblusdoeltreffendheid, ons stel voor om die HFC-227ea brandblusstelsel of the IG541 Inert Gas vuur onderdrukking stelsel. Daar is geen skade aan mense nie.
Stedelike ondergrondse spoorweë is 'n belangrike faktorprogram van stedelike konstruksie, dit is die hoof arteries van stedelike vervoer konstruksie.
Die munisipale regering belê baie in ondergrondse spoorwegkonstruksie, en die spoorlyn word normaalweg in die stampvol strook van die stad gebou, verkeer druk te verlig, as crowded with people, so there is a certain risk of safety after the railway is built.
The railway/metro operates underground, so if the railway gets into an accident and causes a fire, then it will seriously harm our people.
To avoid fire in the underground railways, according to the provisions of <-Kode vir Metro Design>, in the railway system, die kragopwekker kamer, die enjinkamer, die rekenaarlokaal, and the power distribution equipment area are prone to catching fire.
As the railway is a particular place-underground place when we measure fire suppression, we can not be able to use a water-based fire extinguishing device because water-based is hard to reach, we should use a smart gas fire suppression system, om te verseker dat ons die vuur by sy vroeë stadium te vind en te blus die vuur in tyd, en minimum die verlies.
1.1 Subway or Metro Project Overview
Take Metro 1 in Beijing as 'n monster, the construction of Metro 1 is normally designed to cross the main road, the setting railway station is normally at the location of the main road or supermarket, which continues to serve people’s travel and shopping. Byvoorbeeld, the railway station and the local supermarket shopping mall so the metro is very important in the subway construction. the subway plays an important role in underground transportation in urban areas, and it is convenient for people’s travel every day and night.
Fire Safety in the subway is serious and important.
1.2 ontwerp Scope
Subway fires not only cause huge damage to railway train equipment but are also harmful to human health. If one day the railway is shut down due to a fire, all train stations will be paralyzed.
Subway fire protection design should use an automatic fire suppression system and its device, the system should have automatic, manual control, and mechanical emergency start. Op dieselfde tyd, for the design of the manual control system, we should consider awareness and measurement for the manual; the subway should have a different fire supervisor, and every fire zone should use a separate totale oorstromings vuur onderdrukking stelsel.
As the subway is driven by electric power when a fire occurs the water is not able to be used for fire suppression, only a gas fire suppression system is most suitable for the subway fire solutions, but as the subway is underground and crowded with people, so vir keuse van 'n brand blus media / agent moet ons gebruik 'n vinnige vinnige, effektiewe, menslike-veilige gas vuur onderdrukking agent.
There is a definite requirement and provision for a gas automatic fire suppression system when fire extinguishing, which should ensure the subway’s operation is not affected, ensure the subway equipment will not be damaged, and extinguish the fire at its early stage. an environmentally friendly fire extinguishing agent is an ideal extinguishing medium for it, to extinguish the subway fire without air pollution and any harm to the human body.
Considering the atmosphere, the people of the earth no longer use 1301 fire extinguishing agent because it causes pollution of the atmosphere.
Carbon dioxide extinguishing agents put out fires quickly, but due to the narrowness of underground stations and train cars, carbon dioxide can be harmful.
Considering the environment, brandblusdoeltreffendheid, and Human Safety factors, we choose to use the FM200 gas fire suppression system or the IG541 Fire Extinguishing System.
Oorweeg vanuit omgewingsbeskermingsaspek, the indices of ODP, GWP, en ALT is 3 belangrike faktore vir omgewingsbeskerming. the FM200 system and the Inert Gas Fire Suppression system are both perfect.
For travel safety reasons, IG541 is an inert gas, consisting of nitrogen, argon, en koolstofdioksied. Their proportion is 52 VS 40 VS 8. These 3 gasse kom gewoonlik in die atmosfeer voor, daarom, IG541 in the composition is a natural gas.
The IG541 has the following characteristics:
So the IG541 is very suitable to use in the subway or metro as the main fire extinguishing system.
Considering from Usage Cost Aspect, the FM200 and IG541 Inert Gas fire suppression systems are the ideal fire extinguishing systems for the current subway system.
The cost system consists of product purchase cost, maintenance cost, and transportation cost. For the FM200 system, the product purchase cost is slightly higher, while for the IG541 system, the maintenance cost and transportation costs are slightly higher.
So vergelyking van die twee, the cost to them is more or less the same.
After various considerations and implementation results, the IG541 gas fire suppression system is finally the most ideal fire protection system for the subway we chose.
Considering many factors such as economy, omgewingsbeskerming, veiligheid, and efficiency, before establishing a better fire extinguishing system, the IG541 fire extinguishing system should be the most reasonable fire extinguishing system applied in railways or subways.
kleurlose, reuklose, and non-corrosive are the most advantageous of subway fire project installation, ingenieurswese, and maintenance.
IG541 gaseous fire extinguishing agent becomes the first choice for the subway.
