Channel Tunnel

- The Channel Tunnel opened in May 1994 after six years of construction and is the longest undersea tunnel in the world. It actually consists of three tunnels running parallel to each other; the two outer tunnels are used for trains and the smaller central service tunnel is used for ventilation and access.
The two larger tunnels are 7.6m wide and are high enough to take a double-decker bus. They curve gently up and down or left and right so that they can run through the chalk strata. On average, the tunnels are 45m below the sea bed.
The Channel Tunnel has cut travel times between the UK and mainland Europe dramatically. Before the tunnel, it took around 6-7 hours by rail and ferry from London to Paris. Trains can now do the same journey in 2.5 hours.

I have nothing but lots of respect for the people who made this possible.
Yea this is amazing
@@Killerkolt75 yea it’s fucking great isn’t it
The fact that they ware able to do such thing is just amazing respect to who builds it
This helped me so much! I was looking for what the engineers actually did with all of the chalk and I found nothing, but the answer is right here, from a secondary source of course.
It blows my mind that there is a tunnel under water...
brilliant engineering
2:45 what my girlfriend says when I take off my boxers
Good one!
Give us a look
M8 thats a Good one
No homo
Ha Ha Ha Ha Good one!
Lol
Spent 2 years on this project doing electrical
Amazing!
Great Info Thanks!
It’s a bit weird that she’s reading a text so far left of the camera. She doesn’t look into the camera at all.
@Brinta She literally does look into the camera at the end!

You’re right, she does look into the camera for the last 18 seconds of this 6.5 minute video, and therefore my comment was totally out of place.
Good observers, u both r!!
Damn I didn’t know the sea is soo close above you
What a graceful woman
Right: 0:40
Amazing!!!!!
This helped me so much,thenkyou
Nice video but the music is very distracting
Nicely read
This audio was probably a part of my IELTS general test today 😅
Cool
Why the hell I am seeing your face more than the tunnel??
Mans up at 3 questioning all this shit I jus wanna know wtf they doing
When is the tunnel from America to Britain gonna be finished?
I was there
Turns out bad weather was the least of your problems...
Building a railroad/railway tunnel for high-speed train should not be made along a marathon runner (10-60 km), it must be at least minimum of 65 km and a maximum of 6,500 km according to the type and criteria of trains passing in the tunnel. And also the construction of a railroad/railway tunnel project must be within a minimum of 10 - 100 meters from underground, an underwater rail tunnel 10 - 200 meters below the deepest sea level (ocean) and the seabed 10 m - 500 m on the seabed, based on international railway project development regulations in 2010
Why should a tunnel have a minimum length ? If you need a 100 Meter tunnel you build a 100 Meter tunnel. And tunnels are built in a concrete tube in open water today, it does not need to be below see ground. Just the ships above should not collide with the tunnel.
@@holger_p If on the land, building an underground tunnel is better because it is not in the sea, If at sea it must be built from the seabed, not from undersea water
@@madenaraputra6887 Very profound. 🙄
Ridiculous.
Fit
I can't find any information about the 200 meter curve drop between the tunnel ends, due to the earths curvature. How did they dial in the drilling machines to stay in line with the curve? If they did a level tunnel it would end up going towards the surface!
Chinese hoax mate, the Tunnel doesn't exist, just there to make scientists rich, LOL
But the earth is flat
Vertical surveying, probably
They followed the root of the chalk, as she said, so it actually goes up and down, left and right, for the entire length. They followed the chalk line because it was easier to tunnel through.
@@jonathanhutcher9203 Earth is flat? Don’t make me laugh 😆
Terrible sound quality, ruined by loud musical noise!
Add a loudspeaker first, if you can.

deu
who else is here because of zac efron down to earth
I'm here because of you 😘
Me 😁
God that background music is annoying, and completely unnecessary.
she looks on big nerd
"The continent will never be cut off again due to bad weather." No, just due to xenophobia lol
you prolly dont give a shit but does anybody know of a method to get back into an instagram account??
I somehow lost my password. I would love any tips you can offer me!
@Leandro Griffin Instablaster =)
@Sylas Houston I really appreciate your reply. I found the site on google and im in the hacking process now.
I see it takes quite some time so I will reply here later with my results.
@Sylas Houston It did the trick and I now got access to my account again. I am so happy!
Thank you so much you really help me out!
@Leandro Griffin Glad I could help =)
She's boreing, isn't she?
Anything not instant is boring to a childish minded adult.
They worked 8 years before they could even start!
You may not have to "get a life". But her father helped her get a career that she is enjoying!
Respectfully, civil engineering isn't for everyone. Nor indeed is the path of design and creativity.
Fortunately, we do have choices, even if we may struggle to respect those who help to make those possible.
I’m fascinated
BREXIT MEANS OUT, NO MORE TUNELS WITH THE CORUPT EU
Civil engineer your teeth
British teeth..
Better than an American physique
Have another Twinkie you fat shits
what a shallow comment from a shallow person.
@@Annie1962 Pipe down Colonist.
Thumbs up if you've ever gone through the tunnel! 👍
Thumbs down if you haven't!👎
