High-stability steel truss girder pushing and floating towing erection construction method
The invention discloses a high-stability steel truss girder pushing and floating towing erection construction method, and relates to the technical field of steel truss girder floating towing erection construction. Preparation before floating dragging construction of the steel truss girder: constructing a platform on a bridge pier, and arranging a slide way and sliding equipment; a support on the floating towing ship is manufactured; the steel truss girder with a plurality of internodes is assembled above the sliding ways, the steel truss girder is subjected to two-wheel assembling, the steel truss girder is moved to the bridge piers on the two sides through four times of pushing and floating dragging, and finally girder falling of the steel truss girder is conducted. The construction method has the advantages that the overall construction method of on-site assembling, sliding and floating dragging is adopted, the steel truss girder is integrally assembled through two times of assembling, the problem that the operation site of a floating crane is limited is solved, construction is not limited by the site, and the operation difficulty is reduced; the cantilever of the steel truss girder is large, the floating dragging construction difficulty is reduced in a multi-time pushing and floating dragging mode, floating dragging ship construction is more stable, and the navigation requirement can be met in construction.
本发明公开了一种稳定性高的钢桁梁顶推加浮拖架设施工方法，它涉及钢桁梁浮拖架设施工技术领域。钢桁梁浮拖施工前准备：在桥墩上建设平台，设置滑道和滑移设备；制作浮拖船舶上的支架；钢桁梁拼装和浮拖架设：在滑道的上方拼装具有多个节间的钢桁梁，钢桁梁进行两轮组拼，通过四次顶推加浮拖将钢桁梁移动至两侧的桥墩上，最后进行钢桁梁的落梁。本发明的优点在于：采用现场拼装加滑移、浮拖的总体施工方法，钢桁梁通过两次组拼完成整体的拼装，解决了浮吊作业场地受限的情况，施工不受场地限制，降低操作难度；钢桁梁的悬臂较大，通过分多次顶推加浮拖的方式，降低浮拖施工难度，浮拖船舶施工中更稳定，施工中可确保通航要求。
