Large-tonnage box beam erecting construction method for small-radius curve ramp
The invention discloses a small-radius curve ramp large-tonnage box beam erecting construction method which comprises the steps that S1, a bridge erecting machine curve section via hole is prepared, S2, the posture deviation of the bridge erecting machine is adjusted, a third column deviates outwards with the maximum deviation amount P, a first column machine arm of the bridge erecting machine deviates towards the inner side of a curve by m1, meanwhile, a first column cross beam transverse moving sleeper beam deviates towards the inner side of the curve by n1, and the third column machine arm of the bridge erecting machine deviates towards the inner side of the curve by n1; s4, the height of the whole machine is adjusted; S5, the position of the first column is adjusted; S6, beams are fed; S7, the beam falling position is adjusted; the device has the beneficial effects that the bottom of the first column of the bridge erecting machine is provided with the transverse moving oil cylinder capable of realizing fine adjustment of the first column, so that the posture deviation of the bridge erecting machine is adjusted, the bridge erecting machine is adjusted in a posture closest to a curve, a big arm can enter a curve section in a mode that the deviation of the first column is minimum, the adjustment frequency of the bridge erecting machine is reduced, and the adjustment efficiency is improved. The positioning precision of the bridge erecting machine on the curved section upper bridge pier is improved, and the difficulty of small-curve gradient bridge erecting is reduced.
本发明公开了一种小半径曲线坡道大吨位箱梁架梁施工方法，包含S1架桥机曲线段过孔准备，S2架桥机姿态偏移调整，三号柱以最大偏移量P向外偏移，所述架桥机一号柱机臂向曲线内侧偏移m1，同时所述一号柱横梁横移枕梁向曲线内侧偏移n1，S3一号柱支立，S4整机高度调整，S5一号柱位置调整，S6、喂梁，S7落梁位置调整，S8对位落梁。本发明的有益效果为：在架桥机一号柱的底部设置有可以实现一号柱微调的横移油缸，进行了架桥机姿态偏移调整，使架桥机以最接近曲线的姿态进行调整，大臂可以以一号柱偏移量最少的方式进入曲线段，减少了架桥机的调整次数，提高了架桥机在曲线段上桥墩上的定位精度，降低了小曲线坡度架桥的难度。
