A new concept of prefabricated-piled-pier techniques is introduced into the design of an emergency container wharf in the reconstruction of the port of Kobe. Damaged caisson type quay walls are used as earth retainings and steel pipe piles are driven in front of them. Precast concrete procedures for upper concrete works are employedto shorten construction time A precast floor slab with uniform thickness is applied instead of an ordinary beam and floor slab. PC hollow beams are used to connect the gap between them. These concrete members are installed by a large floating crane.
