Tunnels are not all the same. There are tunnels for cars, trains, and pedestrians. Some tunnels are short and others go on for miles. This blog post will highlight a few things that you might want to know before entering a tunnel in order to help prepare yourself for what is ahead. We hope this information helps!
Why Did People Start Digging Tunnels?
There are a number of reasons why people dig tunnels. One reason is to tunnel under the waterways and rivers so that they can meet up on the other side, even if it requires digging through solid ground. In some cases, this also allows two railways lines to cross without interfering with one another’s traffic flow.
Tunnels help protect trains from bad weather conditions as well as reduce noise pollution in urban areas where there might be residential buildings or homes nearby. They can also allow pedestrians and cyclists safe passage across busy roads when crossing by vehicular routes is not an option. Another use for tunnels is for burying pipelines which would otherwise interfere with land development around them while still providing access points at regular intervals along their length.
Which Is The Longest Railway Tunnel In The World?
The longest railway tunnel in the world is currently the Gotthard Base Tunnel, which was opened to traffic on June 2016. It took 17 years of construction and cost over 12 billion euros to complete this mega project which includes a 35-km tunnel through Swiss Alps
Deepest Tunnel In The World
the deepes tunnel in the world is currently, The Marmaray Tunnel which runs under the Bosphorus strait. This tunnel was constructed as an underwater railway tunnel and it’s deepest point measures at 57 metres below sea level
What Are The Methods To Make Tunnels Safe?
there are number of methods that can be used to make tunnel safe, such as the use of fireproof materials and reflective coating on walls.
* Rotating Ventilators- these are placed inside tunnels that produce a natural flow of air by rotating an impeller driven by exhaust steam or gas turbines. * Emergency Alarms – A high pitched alarm activates when smoke is detected so drivers can escape safely from potentially harmful situations.
* Fire Protection Systems – Closed circuit television monitors installed at both entrances alert personnel if there’s any sign of trouble like open flames starting up in the tunnel.
The system will also activate sprinkler heads for automatic extinguishment; this feature is quickly becoming standard practice across many tunnel systems with safety regulations requiring it everywhere now.*
Conclusion
Tunnels play an importent part in our every day life , but not many people know much about them. Hopefully this article has helped to provide you with some new insights into tunnels and their function in our society
