The Channel Tunnel

To celebrate the 30th anniversary of the Channel Tunnel, Practical Engineering takes a look back at the construction and operation of this incredible piece of infrastructure. (Image and video credit: Practical Engineering) Read the full article

This may be a bit of a silly question but I’m trying to research this for a fanclan and I cannot make a fox’s tail out of the non twoleg workings

So how would you/Windclan go about reinforcing the tunnels? Used to think it was just ‘put a thick branch up there and every few fox lengths, it’ll support all that’ and that doesn’t seem quite right anymore. Please and thank you 🐈‍⬛

I'm gonna try and keep this reply simple and not get into the in-depth mechanics of digging holes, that's a post for some other time and I'd have to talk about depth and learn math and shit

So very simply putting it, usually, you would naturally dig square tunnels, and this is where all the tension of digging comes from. See, a square tunnel is really bad for physically holding things up, so beams are there to help.

Think about a tunnel kind of like building a bridge. The tunnel is a structure that needs to hold up the dirt above it. Really, functionally think about how many bridges are truly flat; it's not many! You want Arches.

And, it just so happens, a tunnel ALSO wants to be an arch. I'm not sure if I'm explaining this well so I drew a little diagram of a cave-in;

[ID: A drawing of a square tunnel with a dotted line showing the arch of where the dirt will collapse. It progresses into the second drawing of a rock fall, revealing the arch of the first drawing.]

Most cave-ins aren't the ENTIRE tunnel collapsing, it's the part of the tunnel that WANTS to be arch. Arches good. Arches are physically the best way for holding things up. Problem is that you can't dig like that without dropping however many pounds of earth on yourself.

So really, what you want is a beam, not just a stick in the middle of the hole. You want to put a beam from wall to wall, supported by two columns beneath. Like minecraft.

Other various things;

Older tunnels are, actually, usually more structurally sound. There's been more time for them to "stabilize."

The deeper the tunnel, the more stable. This is because the earth above the tunnel is packed in better. You do NOT want to open up a staircase downwards like minecraft, the entrance will COLLAPSE.

However, naturally, a collapse in a deeper tunnel is more deadly and severe for obvious reasons.

Just to state the obvious, sand bad. You do not want to dig in sand. Sand Bad.

Canon vastly overstates the severity of shallow tunnel collapses. Cats will die in less than a foot of dirt :/ There's this part in DOTC where Jagged Peak activates a quicktime event and a burrow collapses on him and it was so profoundly stupid it's been in my head ever since

suffocating in an old animal burrow... girl... do you think rabbits are constantly dying in collapses? genuinely? In soft soil?

Gray Wing is like, "you almost out bro?" and Jaggy-P is like, "ya im coming" and then WHOMP. DIRT. thats not how this works thats not how any of this works

And as a final note... the problems with WC's portrayals of shitty parents aside, it actually makes perfect sense that Tallpaw would think his father Sandgorse is a lunatic for feeling safe with going right back in after a collapse. Tallpaw doesn't know that some kinds of cave-ins actually make the tunnel more safe, but Sandgorse, an experienced digger, would.

(unfortunately the writers don't know this. but i do.)

Poll Redux: Tunneling

WindClan was unique for their Tunneling and Moor Runner systems back in the day. These systems ended under Heatherstar, but times sure have changed.

Am I the only one who thinks that one of the last things tallstar should have done was bring back the tunneling system when they got to the mountains? like, I think that would have made things alot more interesting and I hate how they introduced the tunneler job thing in Tallstars Revenge (and maybe other books too i dont remember) and dont mention it or bring it back

The first lines of my WIP

I have for you all the first lines of my current WIP, tentatively titled Tunneling unless I conjure something better before finishing it. This is from the prologue of the second draft, but these lines have been through more than just two passes, and I expect this to be just about the final version.

As these are the first words you would read upon opening the book, there is little need for context. All I will give for now is that this is a sci-fi/fantasy story spanning several planets (I find it difficult to pin it to any more specific of a genre). Here are the lines:

For a time, the universe paid no attention to humanity. The reverberations had fizzled into the vastness of space quick enough to make no effect. Stars flew on courses in galaxies groaning to the rhythms designed for them, and the universe was content from the conductor’s seat. Harmony dominated. It was not perfect—it never was. A missed note there. An off-key melody that wobbled some planets. Those had always been fixable, though unfortunately, the best way to stop a faulty instrument from ruining the orchestra was to destroy it. There were plenty of stars to drown the silence that followed. But never before had a broken instrument produced music once more.

My hope is that this sets the stage for the tone of the book, and for the remainder of the prologue, there is a POV character setting the spark for the rest of the story.

(Note from the final author: If you're interested by any of this, I will be posting the premise and some of the worldbuilding behind this series soon. It's planned to be 5 books (with 3 sequel books, of course, because I can't help myself). The series is called Seven Forces in my head, but I will think of a better title eventually.)

Tunneling: Methods and Applications

In the vast realm of civil engineering and infrastructure development, tunneling stands as a pivotal and fascinating aspect. It plays a crucial role in connecting people, places, and resources, allowing for efficient transportation, access to resources, and even scientific exploration. This article delves into the intriguing world of tunneling, exploring various methods, their wide-ranging…

Hey kid, look at me.

I want you to T-pose. Turn your right thumb up and your left thumb doen and look at your right thumb. Move your arms up and down a bit until you feel a nerve running from your armpit to your palm. Now turn your right thumb down and your left thumb up, and look at your left thumb. Keep your chest facing forward and your shoulders back. Move your arms again until you feel that nerve again. Keep alternating between these two for a minute, or look at each thumb thirty times each.

Now sit down. Put your left hand firmly under your left buttock, palm down. Keep your shoulders back and put your right hand over the crown of your head, very gently pulling it to the right. Do this for thirty seconds, then do it again but with your right hand under your right buttock.

These are stretches for the nerves in your arms, and are very good for people who sit behind a computer a lot, or fibre artists, or you name it. Do them daily. They will hurt in the beginning, but keep doing them, even after the pain has gone, or it will return and you'll have to start all over.
