摘要
目前国内铁路建设在道岔连续梁工程施工中,多为等梁高设计、支架现浇施工,我单位施工的道岔连续梁从跨径上及变宽变高上、不平衡施工,结构设计不对称存在较大不平衡弯矩,悬灌施工难度大,施工过程中采用五片桁架组成的挂篮主体与渐变系统、行走系统相结合的方式,解决了施工中的变宽、变高与不平衡弯矩上的困难,取得了明显效果。
At present, the domestic railway construction in the continuous beam project construction, the construction of the bridge, the construction of the bridge, the construction of the continuous beam from the span and the variable width, unbalanced construction, structure design, structure design, the construction process of a large number of difficult, the construction process using five pieces of truss structure with the gradient system, walking system, to solve the problem, the change in the construction, and achieved remarkable results.
