Process method for assembling high-speed rail bridge sections
The invention provides a process method for assembling high-speed rail bridge sections. A large-span bridge fabrication machine is used for splicing high-speed rail bridge sections, and a high-speed rail bridge is divided into multiple sections of precast beams. The process method comprises the following steps: a presetting step: dividing a section of precast beam to be erected into multiple sections according to a preset length in the extending direction of the bridge, and respectively carrying out prefabricated construction to form multiple section beams with preset lengths; a splicing step:splicing the large-span bridge fabrication machine on the erected bridge, and dragging the large-span bridge fabrication machine to the erection position of the precast beam; transporting a pluralityof segmental beams to the tail part of the large-span bridge fabrication machine, hoisting the plurality of segmental beams to a preset position by using the large-span bridge fabrication machine, and splicing the segmental beams; and a fixing step: pouring the connecting parts of the plurality of segmental beams to form a whole-segment precast beam, and carrying out prestress tensioning on the whole-segment precast beam; and for each section of precast beam behind the section of precast beam, respectively executing the preset step, the splicing step and the fixing step until the erection ofthe high-speed rail bridge is completed.
本发明提供了高铁桥梁节段拼装的工艺方法，使用大跨度造桥机进行高铁桥梁节段拼装，高铁桥梁分为多段预制梁，工艺方法包括：预置步骤：将待架设的一段预制梁沿桥梁的延伸方向按预定长度划分为多个节段，并分别预制施工形成多个预定长度的节段梁；拼接步骤：在已架设完成的桥梁上拼装大跨度造桥机，拖拉大跨度造桥机至预制梁架设位置；将多个节段梁运输至大跨度造桥机的尾部，使用大跨度造桥机将多个节段梁吊装至预定位置并进行拼接；固定步骤：对多个节段梁的连接部位进行浇筑以形成整段预制梁，对整段预制梁进行预应力张拉；对于该段预制梁之后的每一段预制梁，分别执行上述预置步骤、拼接步骤和固定步骤，直至完成高铁桥梁的架设。
