The wall and dock walls and the dock bottom on the two sides are of box-shaped structures and are divided into a plurality of closed cabin lattices in the longitudinal direction and the transverse direction, and some cabin lattices are called as water tanks and are used for filling water and draining water so as to enable the dock to sink and float. The bottom cabin can not only ensure floatability, but also support the ship. The dock wall has the functions of ensuring the necessary rigidity and floating stability of the dock and providing space for production.
