摘要
为了进一步提升隧道仰拱栈桥的使用性能,并提高施工效率,提出了24 m履带自行式仰拱栈桥与半幅仰拱模板联合设计施工的方法。优化了主桥结构、前坡桥及整体模板系统,实现了栈桥操作的方便性、配合开挖清渣的便捷性、模板施工的自动性及开挖衬砌同步性,并在黄黄铁路3标段铁家冲一号隧道和刘元隧道项目中试验,验证了该设备的良好性能。
In order to further improve the service performance of invert trestle and improve the construction efficiency,a collaborative construction method of 24 m caterpillar self-propelled invert trestle and semi-range invert formwork is proposed.The main structure of trestle,fore slope bridge and overall formwork system are optimized.The convenience of trestle operation,excavation and residue clean,the automaticity of formwork construction and the synchronization of excavation and concreting are realized.By experiment in huang-huang railway 3 standard Tie-jiachong 1 tunnel and Liuyuan tunnel project,the excellent performance of the device is verified.
