Description

Modular pier capable of realizing high girder height and long column spans

The present invention relates to a modular pier, and more particularly, to a modular pier capable of realizing high girder height and long column spans.

The pier, which is mainly used as a berthing facility on the coast, is composed of a structure in which a plate-shaped deck is connected directly or using a girder on a steel or concrete pillar.
