Check out this storm drain run.

[Chris]

This is a storm drain run of 3-36" HDPE Pipes encased in concrete that we did to re-route a small Creek under a concrete plant.

We have to do those runs in concrete pipe up here. Our soil is much softer and shifts too much. Makes for some looooooooooong days.

Looks good.[insert thumbsup smiley] Looks like the "bosses" truck is bigger than yours. LOL

So the factory is going to be built directly ontop?

On this one a portion of I believe wharehouse was going over this and the rest just outdoor concrete slab. Generally there is not pipe of any kind except for the plumbing of that building under it but there was no where else for it to go in this case. I don't have any pics of the finished product but we encased it all on concrete and then another 12" on top before they even started building anything.

We do them in concrete pipe here as well just not on this job but it would have made it alot easier since the HDPE wanted to float up when we pumped the concrete.

You gotta love coming in the morning and seeing your hard work floating in a ditch. I had a 1200 gal. septic tank go afloat overnight once. Came in and it was rocking back and forth like a damn battleship.

So how did you manage to keep the pipe on grade with it floating like that?

We had two excavators and a few backhoes on that jobsite so we would set the buckets on it to hold it down. Once they were covered they stayed pretty well but we still on poured so many feet a day and left the buckets on til the morning. I will try to find some pics but no garauntees.

Unless you just want to add more pics (and who doesnt like pics?), I get the idea... that was actually my only rational thought about how to do it, just wasnt sure if I was right or not...

In theory, I wonder if you could have capped and flooded the pipes to keep them down?
