multicore trench

[strandgsx]

Okay, have a large gig in a field, with regards to the trench for the multicore, what do you suggest I line it with??? and whats the best way to do it.

 

Thanks

at guilfest 2003, stage 2 was just dug out for the multicore, and nothing was lined in it at all, just the generic dirt that was under the grass. then it was refilled.

Hey,

 

Usually thats all we do, but we have just bought another multicore which cost loads and I want to look after it, hence wanting to line the trench to keep the cable clean.

 

Cheers

How long is the run ? something simple like clingfilm or tarpaulin?

[paulears]

if you want to keep it clean, then drainpipe (assuming the multi-connector fits) - The only snag, as I found out a few years ago, is that you then have too much muck to put back in the hole - meaning a jcb trip to the earth pile (or in my case, a wheelbarrow). Since then it is get it dirty, and hose it down afterwards.

1) Industrial roll of clingfilm

 

2) create a box using scaffold planks and 2x2.

 

3) use those plastic interlocking ramp thingies that cost an arm and a leg

 

4) go to your local quarry, and ask for some old conveyor belt. Many have miles of it, and they can't just chuck it because of their environmental policy. Lay it down over the multi...

Just do clingfilm around the multi. It'll save hours of cleaning. If you're really worried about stoney soil, dig an extra 4 inches down, and fill it with topsoil, lay the cable, then stick some topsoil on top and then finally the turf. That should avoid any stones.

The pragmatist in me says: get it dirty - it will end up that way in the end!

 

When you're washing it, it will give you a good chance to inspect every inch and to make sure it's all in good nick.

 

OTOH, I understand it is your precious new multicore and you want to keep it as perfect as possible.

 

I know which way I'd go.

We had a trench this weekend and we filled it in with dry sand and put the turf over that. The cable just pulls out when youre done. Shouldnt stick to the cores, even theres wet conditions because the turf shelters it and the water takes ages to soak in anyway!

[zonino]

industrial clingfilm every time, unfortunately the person who took it out last unwrapped it... and put it onto the muddy ground!!!?!?!?!?!?!?!?! damn them!

Currently on a site with numerous multicores and control cables etc etc running under ground on an old iron smelting site (I get all te best landscape projects) and we used 20tonnes of beach sand to line the trenches, so far (touch wood) all is well and the cables remove easily. (as the silly person who laid the multi the wrong way around found out!) hehehehe.....(Promise I didn't laugh) ;)

By the way anyone in Cornwall for the next few weeks come and see the show, its at Hayle, we have a flying man on a 20m crane!

Sand works - or just cloth cover it.

 

I had some trimmings from a white cyc cloth (It was going to the bin), about 2' high, and about 10m long. I have an eyelet kit, so I placed eyelets every inch or so, then lace it together. Run the multi down it and tighten. Then when I pulled it up, I just wash the cloth. If I had a longer length, I think it would be a bit too much work to lace and unlace, but since I am rarely more than 10M away, it is fine. I use it even if I am not using a trench, to keep the other cables tidy as well.

Plastic wrapped is the best way to go,

 

Also if you don’t want to pull the cable when removing it from the ground add a run of sting as a breaker to split the well compacted soil. Then pull the cable up,

 

Also, if using pipe,

 

A, make sure connector fits before burring the pipe,

 

B, when trying to pull the plug of the multi down a pipe that’s too small, don’t tie the rope round the plug, tie it to the cable, thus not removing every single returns core from the plug, and making my life more difficult.

 

I hasten to add, it was not me it was like that when I got there! And spent 1 hour trying to make said core work before taking the end off to find the damage that had been done. You never think about looking in the plug as no one would be that stupid! I really should know better by now!

Hi guys

 

On average,how long does it take, for e.g30m trench to be dug?

And what machinery is usually used?

Thanx

Machinery:

2 x Site Crew

2 x Shovel

 

Took about an afternoon for the guys to do it at the racecourse for wychwood festival in Cheltenham in June. They weren't too bothered at doing it quickly. About 30-40m long.

 

I've heard it suggested that a Telehandler with the forks together works....
