摘要
中马友谊大桥地处印度洋低纬度地区,桥位附近海域波浪条件恶劣,具有周期长、波高大的特点。利用波浪实时监测系统+船舶运动姿态传感器对施工船舶进行实时监测,制定合理的船舶作业窗口指导现场作业,提高了船舶作业工效、确保了安全生产。设置辅助平台+悬臂式导向架系统,保证了钢护筒施沉的精度要求。钢护筒施工采用起重船两点起吊翻桩、单点立桩的起重方案,工艺新颖,大幅提高了施工工效。
China-Maldives Friendship Bridge is located in the low latitudes area of Indian Ocean.The wave condition nearby bridge site is severe,presents the characteristics of long-period and large-wave height.Based on the real-time wave monitoring system and the ship motion attitude sensor on the floating crane,the reasonable operation window is formulated to guide the floating crane operation at sea which has effectively improved barge construction efficiency and ensure the safety.By use of the auxiliary platform plus cantilever guide frame system,the accuracy of the steel pipe casing driving is well controlled.The steel pipe casing adopts the method that one floating crane to lift and roll steel pipe casing with two fulcrums,and lift steel pipe casing with the single fulcrums,which innovates the construction technology,and improves the construction efficiency.
