Carlswark Dynamite series.

Thanks, but I think I'll visit Flower Pot anyway, just to see the state of it.

I'm also trying to nip out with a friend who is currently trying to buy Oxclose Mine (!)...(or rather the house that owns the entrance)....

Hmm, still interested in this one.

I know Norman used to have a stack of concrete rings round at his - wonder if they are still there, they have been there a long time. I think that the Flower Pot entrance would be worth re-excavating. How many people would we need over a weekend to sort it? Any permissions needed Andy?

Apparently there is actually a landowner, though we had assumed it was the council at the time, and (in youthful ignorance) just got on and dug it.

Three of us did it over one weenend, and the fill was very solid. It would take much less time now as the fill will be looser...

It has solid walls (its a sort of short rake) Concrete rings may not fit unless they are quite narrow.

what about that black ribbed drainage pipe. Used to great effect at hunger hill swallet. Its perfect for lining small shafts, wont degrade.

Not sure it wouldn't "squash" as the refilled choke settles as the blue drums have done, its something we didnt uderstand at the time. Just a good few tree trunks mixed in with the backfill apparently helps too.

The larger body sized ribbed tubes are pretty tough, and are usually double skinned for extra strength. We use them for culverting gateways. Having said that, the single skinned variant will crush - but only under huge load.
If you want prices, let me know and I'll contact our suppliers.

To be honest, the blue drums (ir they're the ones I'm thinking of) completely lose their integrity when the ends are removed.

Pretty sure they'd stand up to it - you usually see them buried under huge motorway embankments etc. As hughie states - the double skinned ones are tougher.

Much much stronger than barrels as they have actually been designed to withstand a crushing load. The hunger hill swallet one goes down about 15 - 20 feet.  It also stands about a foot proud to prevent flood water from a nearby stream disappearing down it - which was a good idea I thought.

Fair enough, I hadnt heard of the double skinned ones....

...if we could get a length it would be an easy job  Ithink.

Hughie might be able to get you a price, but otherwise - I'd keep you eyes peeled as you drive around. You never know eh. Infact - I think terry worthington mentioned the other night that there was a load of roadworks nr Matlock coming to and end - and there was stacks of the stuff kicking about, might be worth having a word with someone down there, its the type of stuff where there'll undoubtedly be a few lengths or off cuts left over at the end of a job. Needs to be the big stuff though - to cater for the larger caver  :)

Yes, Dynamite is pretty tight if you're biggish build. I used to go there back in the day when i was a skinny lad and had no problems, but when i went back a couple of years ago I got stuck coming back out of the first squeeze which scared the crap out of me :lol:

I'll sniff out some prices from a couple of suppliers.

Have seen largish cavers free dive through the 600mm version, so I'll enquire about that sort of size. There should be some upcoming work on the Levels near me, so, as Sam says, there may be some spare bits around.

That'll probably be at the by-pass near the new Sainsburys (at Cawdor Quarry).

I'm not a complete idiot: some parts are missing!

600 mm sounds about right.

Im trying to find a picture of the stuff on the net. I reckon a company called Naylor Drainage are the guys that manufacture it but their website is "under construction" no pun inteded Im sure. - I know (from googling) that Naylor Ducting, do all the stuff that the highways agency use to lay cables in (purple/yellow/green etc  ~150mm).

Reckon it'll be really costly to buy - espcially in non bulk. but If you can befreind a bod at some roadworks - it might be the best way

Whoever makes it might have sub-standard rejects that they would be glad to get rid of? I have heard of concrete pipe sections being passed on to cavers in similar circmstances. As long as those who use them accept the risk that they might not do the job intended.

At work we've just (as in on thrusday!) discontinued development of our 630mm butt-fusion machine similar to this...

...so i've been investigating the test cutt-offs of pipe. However if you've ever seen a polyethylene pipe 630mm in diameter you'll know that the walls are v thick (~10% dia) meaning that they are VERY expensive and very heavy! Will let you know if i get any oportunities, but don't hold out!

Rob - like the big yellow gas pipe thats been laying all over sheff for the last few years. Indeed - very very heavy.

This Rigid pipe stuff is feather weight - two people can carry a 3m length with one hand each.

Cuts very well "wiv a chainsaw" - bit untidy buy good enough for our uses.
If you're desperate I think we still have a stock of (chainsawed) 2m lenths of blue 630mm HP watermain stuff (if it's not been nicked).
But you'd probably have to fetch if from Astbury (Cheshire).
