Linear deviation rectifying method in continuous steel truss girder construction
The invention discloses a linear deviation rectifying method in continuous steel truss girder construction, and relates to the technical field of bridge construction.The method comprises the steps that the horizontal deviation amount of the axis of a steel truss girder section and the center line of a bridge is detected, and when the horizontal deviation amount exceeds a first set distance, the jacking force of a crawler on the upward deviation side of a transverse bridge is increased; and according to the change of the horizontal deviation amount, the deviation jacking force of the deviation side crawler is gradually adjusted until the horizontal deviation amount of the steel truss girder section is zero. In the incremental launching construction process, the offset of the continuous steel truss girder in the horizontal direction is actively corrected by changing the jacking force on the deviation side, so that the steel truss girder has the designed line type when reaching the set position, the deviation jacking force of a crawler on the deviation side is gradually adjusted according to the change of the horizontal deviation amount, and therefore accurate deviation correction is achieved; and compared with the mode that deviation correction is conducted after the steel truss girder is pushed in place, more convenience is achieved, the construction time is saved, and the construction efficiency is improved.
本发明公开了一种连续钢桁梁施工中的线型纠偏方法，涉及桥梁施工技术领域，该方法包括检测钢桁梁节段的轴线与桥梁中心线的水平偏移量，当所述水平偏移量超过第一设定距离时，将横桥向上偏离侧的爬行器顶推力加大；根据水平偏离量的变化逐步调整偏离侧爬行器的偏离顶推力，直至所述钢桁梁节段的水平偏移量为零。通过在顶推施工过程中，利用改变偏离一侧的顶推力，从而主动纠正连续钢桁梁在水平方向上的偏移量，使钢桁梁到达设定位置时具有设计的线型，且根据水平偏离量的变化逐步调整偏离侧爬行器的偏离顶推力，从而精确纠偏，相比于钢桁梁顶推到位后再进行纠偏，更为方便且节省施工时间，提高施工效率。
