      But like… how did they even do the first step of ramming the wood piles into a deep ass river without big machinery of some kind?

        The machine that shows up about 3 seconds in looks to me like a manual piledriver, uses pulleys and cranks yo pull the weight up, then just gravity to drop it down the track.

        Sledgehammers (or similar) and lots and lots of manpower I’d guess. It’s how they made it watertight before they drained it I’m interested in

          The weight of the water will push wooden pilings together. The flow of water though the gaps will also bring mud and debris into the cracks.

          It’s not perfect, and would need a lot of pumping/water removal, but it’s just a case of manpower, at that point.
