Timber Box Tunnel Design

[Big K]

I need to install a 6" sewer lateral that will run under a storm drain. I will need to tunnel under the storm drain for approximately 15 feet long and 10' deep. I am looking for some sample calculations or suggestions to install a temporary timber box liner. Any help is greatly appreciated.

Thanks

Big K,

This is the welding forum. Are you planning to weld the timber box liner?

Why?

Can't you just auger it? Or similar?

But yes you're in the wrong forum....

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

definitely use oak weld filler.

Sorry about that. Thanks for the help though.
