Steel box girder pushing deviation rectifying structure
The invention discloses a steel box girder pushing deviation rectifying structure, thereby overcoming defects that in the construction process of a cable-stayed bridge, steel box girder pushing deviation rectifying operation is inconvenient, and the deviation rectifying effect is poor. The steel box girder pushing deviation rectifying structure comprises a plurality of temporary piers, a steel boxgirder and pushing assemblies installed on the temporary piers and used for pushing the steel box girder. Two pier columns are arranged on each temporary pier; each pier column is provided with two supporting columns used for supporting the steel box girder. A supporting seat capable of deflecting forwards and backwards is mounted at the upper end of the supporting column; two deviation rectifying beams are mounted on the lower surface of the steel box girder; an L-shaped piston hole is formed in the supporting seat; a pressing plug and a translation block are adaptively mounted in the pistonhole; the space between the pressing plug and the translation block in the piston hole is filled with hydraulic oil; the pressing plug extends out of the upper end of the supporting seat, the translation block extends out of the side face, facing the deviation rectifying beam, of the supporting seat, a return spring is installed between the pressing plug and the supporting seat, a reset spring isinstalled between the translation block and the supporting seat, the pressing plug moves downwards to drive hydraulic oil to flow to push the translation block to transversely move outwards, so thatdeviation rectifying is achieved.
本发明公开了一种钢箱梁顶推纠偏结构，旨在解决斜拉桥施工过程中钢箱梁顶推纠偏操作不便，纠偏效果不佳的不足。该发明若干临时墩、钢箱梁、安装在临时墩上的用于顶推钢箱梁的顶推组件，临时墩上均设有两墩柱，墩柱上设有两用于支撑钢箱梁的支撑柱，支撑柱上端安装可前后偏转的支撑座，钢箱梁下表面上安装两纠偏梁，支撑座上设有L形的活塞孔，活塞孔内适配安装压动塞和平移块，活塞孔内压动塞和平移块之间装有液压油，压动塞伸出支撑座上端，平移块伸出支撑座上朝向纠偏梁的侧面，压动塞和支撑座之间安装回位弹簧，平移块和支撑座之间安装复位弹簧，压动塞向下移动带动液压油流动推动平移块横向向外移动，从而实现纠偏。
