ABSTRACT:
A lightweight concrete floating dock comprised of a plurality of main walkway floats and finger floats comprised of a lightweight but relatively strong concrete shell, a stout inner metal flame and a buoyant foam core. A grid of continuous steel reinforcing is embedded throughout the concrete shell. Utilities are enclosed in conduits within the shell or can be placed in an accessible alternative utility trench. Floats are connected using a hook and eye or swivel type of connection. Docks are positioned using metal cages extending out from opposite sides of floats supporting winch stands with cables attached to anchors along the harbor floor. A stout inner metal frame fitted against the inner side walls of the concrete shell is directly connected to metal elements used for connecting floats, mooring boats and positioning docks, such that all substantial external forces imparted to the dock are endured by the inner metal frame leaving the concrete shell crack and maintenance free.
