Flexible arch construction method based on through steel truss girder
The invention discloses a flexible arch construction method based on a through steel truss girder. The flexible arch construction method is used for arranging horizontal cables, integrally lifting arch ribs, completing arch rib closure, installing arch rib slings and ensuring the structural stability of the through steel truss girder. The method specifically comprises the steps of installing temporary piers, a tower crane base, a first support rod piece and a first arch rib section; installing a second support rod piece and a second arch rib section; mounting third to sixth bracket rod piecesand third to sixth arch rib sections; mounting a seventh bracket rod piece, a seventh arch rib section, a tower crane and a lower tower of a lifting tower; mounting eighth to tenth bracket rod pieces,installing eighth to tenth arch rib sections and an upper tower of the lifting tower; an eleventh support rod piece and an eleventh arch rib section, detaching a mast crane, and installing a horizontal inhaul cable; mounting an arch rib closure section; dismounting the sixth to eighth support rod pieces, and installing three pairs of hanging rods; adjusting a horizontal inhaul cable; removing theremaining assembled supports, removing the lifting tower and installing the remaining suspenders; and detaching tower crane and temporary pier.
本发明公开了基于下承式钢桁梁的柔性拱施工方法，用于设置水平索，拱肋整体提升，完成拱肋合龙，安装拱肋吊索，确保下承式钢桁梁的结构稳定性。具体包括：安装临时墩、塔吊基座、第一支架杆件及第一拱肋节段；安装第二支架杆件及第二拱肋节段；安装第三至第六支架杆件、第三至第六拱肋节段；安装第七支架杆件、第七拱肋节段、塔吊和提升塔架的下部塔架；安装第八至第十支架杆件、第八至第十拱肋节段和提升塔架的上部塔架；安装第十一支架杆件、第十一拱肋节段、拆除桅杆吊机和安装水平拉索；安装拱肋合龙段；拆除第六支架杆件至第八支架杆件，安装3对吊杆；调整水平拉索；拆除剩余拼装支架、拆除提升塔架并安装剩余吊杆；拆除塔吊和临时墩。
