The invention relates to the technical field of net cage culture, and particularly discloses a movable bottom-sitting type ocean platform net cage structure which is low in construction and transportation cost and long in service life and a construction method of the movable bottom-sitting type ocean platform net cage structure. The platform comprises one or more floating piers, hollow columns inserted in the floating piers, a platform layer and a workbench layer, the platform layer and the workbench layer are sequentially arranged on the tops of the hollow columns from top to bottom, fine sand layers are arranged at the bottoms of inner cavities of the floating piers and the bottoms of inner cavities of the hollow columns respectively, and a fine sand layer is embedded in each hollow column, the other end of the pipeline penetrates through the side wall of the hollow column and extends into the inner cavity of the floating pier; and the culture net cage is arranged on the workbench layer. The construction method comprises the following steps: pouring the floating pier and the hollow column to form a pier-column assembly; floating the pier column assembly through seawater and hauling the pier column assembly to an installation sea area; filling water into the floating piers or filling sand into the bottoms of the floating piers and the hollow columns, so that the pier-column assembly sinks to sit on the bottom and is fixed to the seabed; a platform layer and a workbench layer are arranged on the top of the hollow column, and a pipeline is arranged in the hollow column.
