Piping Ditch

[SJM]

Hi, I'm a new member on here looking for some advice on piping a ditch on the farm.

The ditch runs between our silage clamps and a new shed and we are hoping to pipe it to make moving machinery round the yard easier.

A builder piped a small section with 300mm diameter 2.5m long precast pipe a few years ago so would need to be the same material to fit into the existing.

What would I cover the pipe with to allow traffic over it? Few foot of hardcore then a blinding stone on top?

Also, how would I get the level correct as it is over 70m long? Will be opening the existing up with a 360. Haven't done anything like this before but trying to do it myself to save costs!

Thanks in advance.

If it's a well established ditch that is shown on maps it will most likely need council approval to be piped.

But the concept is to clean out the ditch to the original depth and ensure there is a smooth gradient along it.
It can then have either 300mm concrete pipes laid in it or 300 twinwall which is cheaper and easier to handle.
Once these are installed backfill with suitable material use smaller stuff around the pipe first to help stabilise and bind rather than big lumps.
Then top off a surface layer that suits your needs.

If you use twin wall on a yard that will have traffic I'd put some lean readymix over it to protect it.

Also work along a pipe length at a time to get the levels right as you go along.
Bed the pipes on a bit of pipe bedding to help

Thanks for replying. The ditch was piped with terracotta pipe many years ago which have now collapsed in and over grown with trees so the idea was to dig it all out and start again.
Would that still need planning?

I have brought some seconds concrete pipes already, will bind them in with smaller stone first like you say. Thanks

If its already been piped then you are just updating and replacing damage so there is no need to get the council involved.

If it's a ditch now can you not tidy it up with ditching bucket and deepen it slowly as uou go along, get it running right before you put the pipe in. No better spirit level than water!!!

If you are going to use shortish concrete pipes I like to get the ditch running right and then dig a concrete block in at the joins so that the flanges are easier to line up and it helps prevent the pipes going out of line.

In a yard I would dry-lean over the pipe too as traffic will always get heavier in the future.

Thanks for all your ideas. How much dry lean would you cover the pipes with? Thanks

Get yourself a laser level and take the level from one end and the other then split the difference over every 3metres of pipe.

Best way to support the start and end of pipes is building a head wall at each end
