摘 要:随着一带一路的实施,我国在国外钢架桥施工越来越多,为减少大型起吊设备的限制,拖拉法具有将施工中各个系统分离运输安装,部分工装现场制作的优点。达到节约成本的效果。在国外钢架桥施工中运用较广。以厄瓜多尔西蒙玻利瓦尔公路项目的威俪萨桥为研究对象,总结钢架桥推拉法系统组成,各工序注意事项,施工中测量监控要点,现场控制方法,展开钢架桥拖拉法的技术应用研究。充分挖掘推拉法的工法优点。With the implementation of one-way construction,more and more steel framing bridges are constructed in China abroad.In order to reduce the restriction of large-scale lifting equipment,the traction method has the advantage of separating,transporting and installing various systems in construction and making some tooling on-site,thus achieving the effect of cost saving.It is widely used in steel frame bridge construction abroad.This paper takes the Velisa Bridge of the Simon Bolivar Highway Project in Ecuador as the research object,and summarizes the composition of the steel frame bridge push-pull system,precautions for each procedure,key points of measurement and monitoring during construction,and on-site control methods.In this paper,the technical application research of steel frame bridge pulling method is also carried out and the advantages of pulling method are fully excavated.
