Large-section hoisting method for offshore wide-section steel box stiffening steel truss continuous beam bridge
The invention relates to an offshore wide-section steel box stiffening steel truss continuous beam bridge large section hoisting method, belongs to the technical field of bridge engineering construction, and aims to solve the problems that when a steel beam is hoisted at present, a suspension arm of a floating crane easily exceeds the aviation height limit, the hoisting weight is small, and hoisting is inconvenient. The characteristic that the small carrying pole beam is light in self weight is fully utilized, the hoisting weight of the floating crane is increased, the hoisting capacity of the floating crane is fully utilized, guarantee is provided for safe hoisting and accurate positioning of the segments, meanwhile, the hoisting amplitude of the floating crane is reduced, channel navigation is not affected when the segments of the side span are hoisted, and the navigation and aviation height limiting requirements are met; and after the steel beam sections are positioned, temporary connection is not needed, welding is directly conducted, efficiency is improved, and the construction period is further shortened. The hoisting method provided by the invention meets the technical requirements of hoisting the large-section steel beam, and leads the technical progress and innovation of superstructure construction of bridge engineering.
本发明涉及一种海上宽断面钢箱加劲钢桁连续梁桥大节段吊装方法，属于桥梁工程施工技术领域，本发明为了解决目前钢梁进行吊装时，浮吊吊臂容易超过航空限高，吊重富裕小，且吊装存在不便的问题。本发明充分利用小扁担梁自重轻的特点，增加浮吊的吊重富裕，充分利用浮吊的起吊能力，为节段的安全吊装、准确定位提供保障，同时降低浮吊吊幅，边跨的节段吊装时不影响航道通航，满足通航及航空限高要求；钢梁节段定位后不需要设置临时连接，直接进行焊接，提升效率进一步地缩短了工期。本发明的吊装方法满足大节段钢梁吊装的技术要求，引领了桥梁工程上部结构施工的技术进步和创新。
