Maximum trenching depth?
Maximum trenching depth?
(OP)
Hi All
We are in the conceptual design phase of a deep (6 - 9 meter) 1200 mm diameter sewer tunnel and I am doing the options costing: deep trenching/open cut versus tunneling/trenchless.
My question is "What is generally the maximum depth for open cut/trenching"?
Thanks

So I would say the maximum standard trench depth is about 12'.

No idea how you'd install a utility in such a trench though. . .

you could do some fairly deep trenching for less than the the cost to mobilize and operate a microtunneling rig to install a 1200 gravity sewerline.
