恶劣海况下码头工程施工工效提升方法

Construction efficiency improvement methods of wharf engineering under severe sea conditions

为在可作业时间短且不连续海况条件下快速、高效、经济、安全地进行独立式墩台施工,采用全回转打桩船沉桩,在沉箱盖板上搭设施工平台,利用履带吊吊装立柱钢筋笼和钢模板、电机控制料斗启闭浇筑立柱混凝土、运输驳上放料槽运输混凝土长臂勾机浇筑墩台混凝土。通过采取一系列措施加快施工进度,保证了工期,节约施工成本,提高工效,确保人员安全,积累了恶劣海况下独立式墩台的施工经验,以供同类工程参考。

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.
