Hole-by-hole erecting method for large-span continuous steel truss girder
The invention discloses a hole-by-hole erection method for a large-span continuous steel truss girder, and relates to the field of continuous steel truss girder erection construction in highway or railway bridge engineering. The method comprises the following steps: erecting a first-hole steel truss girder; adjusting the position of the first-hole steel truss girder, and installing a permanent support; transporting a hanging bracket to a pier position to be erected, and installing the hanging bracket on the first-hole steel truss girder; erecting a next-hole steel truss girder; carrying out welding closure on the first-hole steel truss girder and the next-hole steel truss girder; and continuously erecting the rest hole steel trusses in each link hole by hole to finish the erection of all links of steel trusses. According to the hole-by-hole erecting method for the large-span continuous steel truss girder, the erecting efficiency can be improved, safety and reliability are achieved, andthe hole-by-hole erecting problem of the large-span and large-tonnage porous continuous steel truss girder can be effectively solved.
本发明公开了一种大跨度连续钢桁梁逐孔架设方法，涉及公路或铁路桥梁工程中连续钢桁梁架设施工领域，该方法包括以下步骤：架设首孔钢桁梁；首孔钢桁梁位置调整及永久支座安装；运输吊架至待架桥墩位，安装吊架于首孔钢桁梁上；架设下一孔钢桁梁；进行首孔钢桁梁与下一孔钢桁梁的焊接合龙；每联之中其余孔钢桁梁连续逐孔架设，完成所有联钢桁梁的架设。本发明中的一种大跨度连续钢桁梁逐孔架设方法，其能提高架设的效率，安全可靠，能有效解决大跨度、大吨位多孔连续钢桁梁逐孔架设问题。
