Piping a stream

[jackstor]

We are wanting to gain access to a field across a stream. Don't want to put a bridge across as it will jut into the field. It'll mostly be for livestock but sometimes tractors.
Stream is approx 8ft wide with the banks 3ft high. I was thinking about widening it to help the flow then using perhaps 3 3ft pipes. In high rainfall the stream will probably overflow over the top.
Would twin wall plastic be strong enough or concrete be better? Tractor and forage wagon or muck spreader could be getting up to 20tons. Would it be best to put a covering of stone over the pipes then a layer of concrete with mesh in it?

i've done one with twin wall, forget how wide, poss 9 inche dia then banked up with rubble another 6ft and that's been fine with concrete sleeper track and tractor/ spreader going over, but if you've got the money maybe concrete instead

The depth of the stream will only allow a small amount of cover over the pipes so I was thinking a slab of concrete would prevent the pipes from collapsing and when the stream overflowed it wouldn't wash the stone away.

@Kevtherev is the professional, he might know exactly what to do

You will need a culvert permit from your local council if you are in England.

Lego block dropped in middle and concrete slabs either side

 

[Kevtherev]

Large diameter concrete pipes big enough to take the flow during high rainfall.
The other cost effective way would be to cut the banks each side and make a Ford or crossing place if possible?
Photo of stream would help.

If you only put 9ft of pipe in ,,by the time its back filled and the end walls shaped ,it would only be about 6ft wide on the top ,,better of putting 15ft in to finish on top at 12ft

What about concrete railway sleepers, the crossing sleeper type? I believe they range from 12' to 24' long. Get a good matching set of those and it would be a cheap bridge and no flow restrictions on the water .

Ea will want to know about it if it's their watercourse too.

Here's a photo

So I was thinking 3 3ft diameter pipes, 12ft long. That would take the pipes nearly up to the top of the banks. Then a covering of stone and if need be, a slab of concrete.
I was thinking plastic will be a lot easier to handle than concrete pipes, but I haven't priced any up yet and I don't know what weight they can carry?

 

[Kevtherev]

Twin wall is ok but take care when covering them ie no large stones or rough stuff on them.
I think for cheapness I'd grade banks off and make a crossing place

 

[Kevtherev]

I've just been quoted £210 for twinwall 600mm 6 metre length for a job

Strong bank on left and sloping on right... Hmmm... Pretty sure You can get 12ft long concrete slabs. 3 slabs wide would be grand. Would piping just be extra expense

 

[jackstor]

A ford would work OK at this time of year,apart from it would eat into the field, but I wouldn't like to take the gator across it in the winter, could end up downstream!
If we were to put a bridge in, would it need founds in to set the panels/sleepers on to stop them sinking?

 

[Kevtherev]

Yes you could use either concrete supports or gabion baskets if it's only for a gator or quad I have seen a lorry body used as a bridge.

JFDI!

get a long lorry body plenty over each side to sit on the banks,
