    I’m with N/a that they are sheet piles for support of excavation. Sometimes there are obstructions (large boulders, concrete slabs, etc.) that prevent the piles from being driven farther into the ground. The work is associated with the Main Pumping Station Diversions associated with the DC Clean Rivers Project.
