Draw wire through 130m duct
I need to get a draw wire through a 130m of buried duct its 140mm
internal dia, it does have slight smoothe bends nothing serious, So far compressed air and a carrier bag has been pondered as too has a radio controlled car the latter of the two I am reluctant to try due to possible rain water sitting in the bottom. Any good suggestions? |

Any good suggestions? Compressed air is probably the way to go, but you will need a vast air reserve - I calculate volume as 0.2 cubic metres or 7 cubic feet. You need a compressor that can dump several times that quickly. Begs the question why a draw rope wasn't inserted as it was laid. AWEM |

Firework rocket with fine wire Big magnet on surface to pull a metal weight along (you need one of the Acme brand magnets that doesn't obey the inverse square law). Collect tent poles from the abandoned junk after a rainy pop festival and use them to push through. Andy |

You could probably waterproof one well enough to handle water once, and if it fails drag it back out. (making sure your draw wire is strong enough!) No it's an absolutely terrible idea that may require digging up several areas of the ground and opening the pipe to discover where the radio controlled car has blocked it. RC signals don't pass through damp earth too well anyway. Underground cable ducting does flood, it also fills with grit and other ****. Big huge nylon feed-wire is a good choice. The compressed air system and "rabbit" is commonly used by some utilities. But they tend to use their jack-hammer compressor. -- Clive Mitchell http://www.bigclive.com |

I've got an offcut of one, about 20-25m long, that I have for long runs on trays, above ceilings etc. It's flaming lethal, you have to unwind it gently then run when it starts to let go and try and lay itself out flat! You wouldn't think it was that dangerous after using one that comes on the reel as it just rolls on and off easy as anything. -- Regards, Stuart. |

Any good suggestions? Instead of compressed air - how about a vacuum cleaner and a carrier bag (attached to fishing line) I know this work really well for smaller ducts, and I have done it several times, but on your run and bore, you might need a "super Hoover" to make it work! Or if the run is down hill, then you could attach a tennis ball to a line, then squirt water down. to push it through BT/NTL etc have a fiberglass rod on a reel, but I doubt that it would be 130m long as they usually have pits in the road/pavement a lot closer than that - might be worth asking your friendly BT employee when you see one. Tie/tape a line to a rat's tail, it will probably end up the other end, eventually!! A large-ish firework rocket with the stick removed may well work, but I guess you would need the first meter or so of line to be metal, or it would probably burn/melt!..preferably one that doesn't end with a large BANG - one of the screamers would be best I guess Sparks... |

You didn't read any of the other replies then. You're comment about the rolls that BT use not being 130m because they are closer, what does that mean, I can't work it out. -- Regards, Stuart. |

Using vacuum you're restricted to atmospheric pressure - at very best. No such restriction with compressed air. If you've got a vacuum which blows as well as sucks, the blow part will be more efficient. -- *If at first you do succeed, try not to look too astonished.

There are many who read an o/p's post and reply without any reference to the rest of the thread, leading to many diverging non-solutions. I'm sure the o/ps reads all the posts so will see the useful stuff. That said, many o/ps don't acknowledge helpful posts.

Catherine Aird If, and it is a BIG IF, you can arrange a large water tank at the head end of the run, and can let water quickly disperse at the tail end, rather than use an air compressor you could tie a stout cord through a suitable sized ball, and wash it down with a rapid pulse of water. This assumes there is a fall of course. AWEM |
