摘要
崇贤特大桥是宣杭铁路复线的重点控制工程之一,其中第40号～41号墩跨间梁部为1×64 m栓焊下承式钢桁梁,跨越杭州市北绕城高速公路崇贤高架桥,钢桁梁架设施工中采取在高架桥两侧用军用墩搭设2个临时支墩,同时利用高架桥桥梁中分带70 cm的空隙,用8根[30槽钢对扣搭设临时支墩,在不加前端导梁的情况下进行反向拖拉,顺利完成了钢桁梁的架设施工.
Congxian Outsize Bridge is one of the major projects in the railroad double line of the city Xuan cheng to Hangzhou. The beam from NO. 40 to NO. 41 pier which spans Congxian viaduct of the north freeway around Hangzhou city, is 1.64 m slug welding through steel beam. During the steel boom erect construction, two military piers were used beside the viaduct as temporary abamurus. At the same time, making use of the 70 cm interspaces of the viaduct, eight irons were used to erect temporary abamurus, making reverse drag without front-end nose girder, and successfully accomplished the erect construction.
