近日,在中国建筑工程总公司所属中建六局承建的盘锦内湖大桥项目举行的大型旋挖钻机交流会上,中国建筑与中国南车共同研制的亚洲最大旋挖钻机TR550型旋挖钻首次对外亮相。盘锦内湖大桥项目地处辽河入海口,海上吹填地质对桩基要求非常严格。该项目最大桩基孔深120米,桩径3米,需浇筑混凝土方量800立方米,是国内目前最大的桩基之一。在施工过程中,中国建筑与中国南车积极采取技术探讨、性能改进、整机优化等一些列措施,成功研制出能够实现 Recently, China Construction and CSR jointly developed TR550 rotary drilling machine, the largest rotary drilling machine in Asia, for the first time at a large rotary drilling rig exchange meeting held by the Panjin Neihu Bridge project under construction undertaken by China State Construction Engineering Corporation Appearance Panjin Neihu Bridge project is located in the Liaohe estuary, the sea filling the geological requirements of the pile is very strict. The project has a maximum pile hole depth of 120 meters, pile diameter of 3 meters, the concrete side to be poured 800 cubic meters, is currently one of the largest pile. During the construction, CNBM and CSR took active measures such as technical discussion, performance improvement and machine optimization, and successfully developed a series of measures that could be implemented
