Temporary shoring - 30' diameter, 36' deep shaft
Temporary shoring - 30' diameter, 36' deep shaft
(OP)
I need to design temporary shoring for a 30' diameter, 36' deep circular shaft. I'm thinking of using rolled steel beams with wood lagging. Any comments or other ideas?

How is it going to be excavated? Does the shoring go in as the shaft goes down? Sheet piling may be the best approach and add walers & tie-backs as needed as the excavation proceeds.

Sheet piling is easy to install and extract.

Ring beams are cast as required during excavation. The spacing between rings will depend on soil conditions and pile section modulus. Rings are connected to the sheets to prevent them dropping down.
