Anyone bridged a drain?

jp6470

Possibly covered before,tired a quick search but didn't see anything.

Has anyone ever done so.? Was dreaming the other day,if I had a good big precast floor slab.could be cheap solution. The drain is wide,and deep.

Reason being for cattle,it would leave all my fields adjoining.and I could graze them back to the yard.and get them down to yard/crush handy,without loading in bottom fields or herding down the road.

Was laughing at a bodge I saw in France on holidays.
40ft container with the end cut out. Had it Across the river. Could even use the doors to close it off.

A large concrete pipe and back fill with earth.

We put in concrete pipes in a drain before, but it's the sides that are the problem. Vertical sides don't work, as there is nowhere to anchor them. Sloped sides with extra pipes ares probably better.
These 'culverts' I think would be a great job.

That has been done in all the fields here. Its a big concrete pipe bigger than 2ft wide id say and just filled level to the top of the field with ready mix

Yea that would be the easiest.but it's very fast,flowing,floods runs for miles and have seem men in yellow coats around it in my time.so that's why thought something over and not in.

If you can get this months Practical Farm Ideas there was a farmer that made his own bridge . He made the walls with footing and all on them so all he had to do was dig out the sides level and to the right depth and then drop them in . He precast the top in two halves that spanned the river and I think bolted them together in place then . It was a cheap andsolid job without having to do much in the water at all.

If it only 4' would a couple of tractor slats span it for you ?

I have done it and it works a treat.. just dig back into nthe banks a bit. form up a bit of shuttering and drop your slab on top. most of these slabs will require a secondary pour on top of the slab.

Saw one on twitter built with telegraph poles (that's what I thought they were) and wood planks then on top. Nearly sure it was a kilkenny farmer

Well that could be cheaper that a slabs.edit on 4ft don't know why put that,they could step over it if that's all was it was.its twice that.

Concrete pipes and backfill you would think they were always here and handled lot of fast flowing water in last year and not a bother on them.

+1, we've done a few times. 4 concrete pipes backfilled and no retaining walls needed. We backfillse with stone as it was part of a cow roadway

did one last week... grand job...

bogman_bass

how long are the pipes? it would want to be very wide at the bottom wouldnt it?

whelan1

the pipe we had was about 15 foot long and acout 12 inches wide-at least-, dont know where we got it was lying in yard for years

dharn

What width and what depth is the drain ,what is the maximum depth of the water and is it fast flowing, what sort of soil is the banks made of , all these have a bearing on what you can use

we put in concrete pipes side by side and backfilled.
Think they are 600mm ID.
one pipe could of done it but put 2 side by side for storm capacity.
good job
think the stream is about 5ft wide.

Caution required if the stream/drain has Salmonids or Salmonid holding capacity. You could fall foul of fisheries legislation.
You need to identify which river basin district you're in and talk to the relevant office. Sometimes a seemingly insignificant stream can have huge importance. The opposite is also true.

We bridged a stream on our farm with 2 tractor slats a number of years ago. built up the bank with stones concrete and a couple of old gang slats. it's used for bot the cows and we can drive across with the tractor and tidy implement like a fert spreader or mower..

nashmach

Have a good few done here too for over 20 years.

Big pipe and then filled up with filling.

Thick vertical walls to finish off, probably 14 in thick and all mixed with a tractor mixer!

10ft trailed mower has no problem crossing.

agriman27

I have a sizeable river I'd like to bridge it's about 15ft wide at the crossing point. I saw a tipper body on done deal its 22ft long and would do the job. Only thing is would it be wide enough I'd say its only 8ft inside. No silage machinery needs to use it.

Very tidy job. I bet you've never regretted it.
