Assembly type bridge integrated transporting and erecting construction method
The invention belongs to the technical field of road traffic transportation, and particularly relates to an integrated transporting and erecting construction method for a fabricated bridge. Construction procedures are reasonably planned in a fixed time period, a completed on-bridge structure is used as a transportation channel, a beam erecting machine and a pier erecting machine are coordinated and matched, the time for erecting a pier main body and connecting the pier main body with a bottom bearing platform is used for transporting a prefabricated box beam main body, and the procedure for erecting the box beam main body is implemented; and the cast-in-place concrete equal-strength process between the bridge pier body and the bearing platform is conducted at night time, the initial condition of next hole erection circulation is guaranteed, iteration is conducted step by step in each circulation, and finally transportation and erection integrated construction of the overall assembly type bridge is completed. The problem that in the prior art, cast-in-place concrete cannot carry out load bearing in the equal-strength process is ingeniously solved, so that the advancing construction time of each span of the fabricated bridge is prolonged, the integrated erection construction period of the whole bridge is prolonged, and the construction cost is increased.
本发明属于道路交通运输技术领域，特别涉及一种装配式桥梁一体化运输架设施工方法。通过在固定的时间段合理的规划施工工序，利用已经完成的桥上结构作为运输通道，使架梁机和架墩机两者协同配合，将桥墩主体的架设、桥墩主体与底部承台连接施工的时间，同时用来运送预制箱梁主体，并实施架设箱梁主体的工序，利用夜间时间进行桥墩主体与承台之间的现浇混凝土等强过程，保障了下一孔架设循环的初始条件，每个循环逐步迭代，最终完成整体装配式桥梁的运输架设一体化施工。本发明巧妙地避开了现有技术中现浇混凝土在等强的过程中不能进行承重从而延长了装配式桥梁每一跨前进施工的时长，进而使整体桥梁的一体化架设施工周期延长，增加了施工成本。
