Steel truss arch bridge and construction method
The invention discloses a steel truss arch bridge and a construction method. The steel truss arch bridge comprises main piers, tie bars, steel pipe piles, temporary buttresses, chord members, hangingrods, support steel pipes, support crawling ladders, #-shaped ladders, steel bar hanging cages, leveling steel pipes, H-shaped cross beams, cross beams, movable longitudinal beams, channel steel, a guardrail with a safety green net, flange plates, steel pipe stand columns, a jig frame, an anti-falling net, a rest platform, longitudinal-transverse bridge construction channels, wood springboards andguardrail net arch ribs. According to the construction method, construction is conducted according to the sequence of first bridge and then arch. The construction method comprises the following stepsof firstly mounting side spans and combination sections, then mounting mid-span bridge decks, finally mounting main arch rib hanging rods, chord members, transverse braces, parallel braces and web members, assisting construction by utilizing a temporary buttress system, arranging safety protection crawling ladders and #-shaped ladders at the side parts of temporary brackets, and erecting construction channels between the temporary brackets. Working of workers among all parts is facilitated, and the safety coefficient is increased.
本发明公开了一种钢桁拱桥及施工方法，钢桁拱桥包括主墩、系杆、钢管桩、临时支墩、弦杆、吊杆、支架钢管、支架爬梯、井字梯、钢筋挂笼、调平钢管、H横梁、横梁、移动纵梁、通道槽钢、带安全绿网护栏、法兰板、钢管立柱、胎架、防坠网、休息平台、纵横桥向施工通道、木跳板、护栏网拱肋，施工方法采用先桥后拱的顺序进行施工，先进行边跨及结合段安装，再进行中跨桥面板安装，最后进行主拱肋吊杆、弦杆、横联、平联、腹杆安装施工，利用临时支墩体系辅助施工，临时支架侧部设置安全防护爬梯及井字梯，临时支架之间搭施工通道。本发明方便了工人在各个部件之间的作业，增加了安全系数。
