Technical Problem

[0002]造桥机是一种用于桥梁施工的大型移动式设备,能够实现桥梁上部结构的现浇混凝土或节段拼装作业,与现有造桥机技术相比,仍有如下缺陷:1、以往造桥机只能沿线路向前顺序推进施工,如遇现场施工断点多的情况,往往需要进行反复安拆转运,安全风险高,施工繁琐;2、其结构箱型结构布局紧凑,净空不足,采用封闭式的截面,自重大,稳定性不足;3模板拆除时需人工在狭窄悬空作业平台上拆卸高强螺栓,同时多台千斤顶协同作业,易因受力不均匀导致倾覆,操作繁琐,安全风险激增;4、其主梁结构采用固定横向定位设计,缺乏主动横向调位机构,导致在复杂桥梁线形施工中暴露出显著局限性

Benefits of technology

1、该实用新型具备安装便捷高效、调试简单,结构重心低,行走快速便捷的特点,在行走过程中,可实现模板与主体结构的同步前进与后退,在桥上直接调转方向施工新的工作面,降低了拆装安全风险和因调头引起的窝工损失,缩短施工工期,节约施工成本。
