I like it. Couple of thoughts:

after getting the water and soil out, there will be a significant buoyancy force trying to pop the tube upward. Best be ready to fill it with concrete. Maybe not take all the soil out - especially if you get into something solid.

To attach your joists/beams, drill holes for 5/8" or bigger galvanized all-thread and put them in as you pour.

My pond filled before I got to the dock so I drained it. Amazingly while using an auger the clay was still bone dry about 8 inches down. Note the bolts I have attaching my beams to my power pole pillars. edit - guess they are hard to see. Buddy had access to used power poles and hardware
