Pier and beam integrated bridge girder erection machine and hole passing construction method
The invention provides a pier and beam integrated bridge girder erection machine and a hole passing construction method, and belongs to the technical field of bridge erection, the pier and beam integrated bridge girder erection machine comprises a longitudinal guide beam, a main beam, a crown block, four sets of support leg devices and a cross beam. The main beam is installed below the longitudinal guide beam, the cross beam is connected with the longitudinal guide beam, the crown block is installed on the cross beam, and the support leg devices are installed below the main beam. A carrier roller assembly and a hanging assembly are arranged on the support legs, the carrier roller assembly drives the main beam to move in the front-back direction, and the hanging assembly drives the support legs to move in the front-back direction. According to the machine, the pier columns and the split cover beams in the span are firstly installed, then hole passing operation is conducted to the next span to conduct pier column and cover beam hoisting operation, circulation is conducted, the pier columns and the split cover beams in the whole line are installed through one bridge girder erection machine, the problem that the wet connection waiting time of the split cover beams is long is solved, and the construction efficiency is high. Hoisting operation of pier columns, bent caps and box girders can be completed in an operation area with poor foundation bearing capacity, the foundation does not need to be reinforced, construction cost is low, and safety risks are low.
本发明提供了一种墩梁一体化架桥机和过孔施工方法，属于桥梁架设技术领域，包括纵导梁、主梁、天车、四套支腿装置以及横梁。主梁安装在纵导梁下方，横梁与纵导梁相接，天车安装在横梁上，支腿装置均安装在主梁下方。支腿上设置有托辊总成和吊挂总成，托辊总成驱使主梁在前后方向上移动，吊挂总成驱使支腿在前后方向上移动。本发明先安装本跨内的墩柱、分片式盖梁，再过孔作业至下一跨进行墩柱、盖梁吊装作业，循环往复，将全线内的墩柱、分片式盖梁使用一台架桥机完成安装，解决了分片式盖梁湿接等待时间长的问题，施工效率高。地基承载力不好的作业区域也能完成墩柱、盖梁和箱梁的吊装作业，无需加固地基，施工成本低，安全风险低。
