Chamber for drains

[teslacoils]

Old drain chamber is a nasty disaster. Presume I just dig the whole thing out, put a concrete base in, brick up to the surface and put a lid on it?

Three 4" drains in, and into a 12" culvert. Thought about 4 foot square would be big enough. Sump? Concrete type? Brick type? Or pay someone who knows how to do it?

concrete base but then use rings, easy to handle and rise 1m a go, makes life easy so long as bass is level!

 

[Lincs Lass]

Use square rings ,,they come in smaller depths

I have cast mine, bit awkward making the shuttering but folded weldmash cage as reinforcing. You can cast the bottom in the same our too but you have to fill the centre with concrete blocks to stop it floating out as you poke the wet concrete.

A section of big twin wall culvert pipe ,,easy enough to cut the entry and exit points ,,dig the hole bigger and back fill with concrete ,,cast a 6inch thick lid with a 600mm sq cast chamber lid ,,I made one for my landlord long time ago for a brick pit where the mains water pipes split in different directions

Currently laying fresh concrete in part of yard and wanting to bury a chamber and cast grid on top to take away surface water. Are these plastic ones with collars and then put concrete around and on top strong enough to withstand occasional heavy traffic such as 14t trailer full of maize? Or would brick chamber be better?

 

[Lincs Lass]

As long as the lid is cast iron or better still a solid plate and the ring is bedded in well ,,the concrete around the plastic will take the weight

We've done blocks, old barrels and concrete rings with a biscuit on top. Any I do now will be precast rings. The time savings are worth the outlay.

900mm deep ring, concrete biscuit to go on top, d600(I think) rated man hole cover and a bag of quick setting cement to bed it on was £270 delivered in Jan I think.

How do you put the pipes through the concrete ring. Is it just a case of knock a hole in and make good with mortar after. I want to make a catch pit so was thinking of doing something similar.

Yes, but usually with a diamond bladed saw.

The one we had done when building shed the digger man got a plastic junction peice at bottom for 4 pipes. Bit of ready mix then ring on top.

Does anybody make a manifold base to go under a 900 diameter chamber ring, save a lot of time flaunching the pipe entries and exits if so, that is where the work is.

It wont be cheap if they do, plastic for burying seems to be very expensive.

Yes our digger man got a 4 way plastic bit to go under ring. Not sure where it came from though.
Ring was then placed on blocks and bottom concreted in.
Like this but 4 way

Thats little one for normal house drainage, you also need the risers and lid specced to traffic load.

We just used the base piece then a concrete ring.

So you used this little one inside a big concrete ring, did you just hold the ring clear of the pipes then run concrete under it?

I think we set the ring on blocks placed between pipes then shoveled in some fairly dry concrete.
Will try and get a pic of it tomorrow.
