O-PILE INSTALLED THROUGH ROCK JETTY

See enclosed project specifications here. You can also see how a Combined King Pile system was replaced by an O-Pile 102-978. For further information, see full project description here and Wikipedia page here.



THE PROJECT

The Parallel Thimble Shoal Tunnel Project will construct a new two-lane tunnel under Thimble Shoal Channel. When complete, the new tunnel will carry two lanes of traffic southbound and the existing tunnel will carry two lanes of traffic northbound.



Construction Start (estimate): October 1, 2017

Construction Completion (estimate): 2024



THE CHALLENGE

Install a sheet pile wall in pure rock



THE SOLUTION

It is Mott MacDonald’s opinion that the 36-inch diameter O-Pile offers substantial improvement for movement control with very little additional steel over the length of the SOE walls, and as such we recommend a 36-inch O-Pile solution be deployed.
