To construct independent piers and abutments quickly，efficiently，economically，and safely under short working time and discontinuous sea conditions，full rotation piling barges are applied to sink piles；construction platforms are set up on the caisson cover plate；crawler cranes are utilized to lift the column reinforcement cage and steel formwork；motor controlled hoppers are adopted to open and close the column concrete；long-arm hook machine is used to transport concrete to the chute on the transport barge to pour the pier and abutment concrete.By taking a series of measures，we guarantee the construction period，save cost，improve work efficiency，and ensure the safety of personnel.In addition，the construction experience of independent piers and abutments under severe sea conditions is accumulated for reference of similar projects.
