Prefabricated box girder multi-section cantilever asymmetric splicing system and method
The invention relates to the technical field of bridge construction, and discloses a prefabricated box girder multi-section cantilever asymmetric splicing system and method. The prefabricated box girder multi-section cantilever asymmetric splicing system comprises a first suspension splicing device, a girder conveying device, a second suspension splicing device and a lifting device, the first suspension splicing device is located on one side of a bridge pier and abutment and comprises a first truss structure, a first moving platform and a first lifting appliance, and the second suspension splicing device is located on the other side of the bridge pier and abutment and comprises a second truss structure, a second moving platform and a second lifting appliance. The second suspension splicing device comprises a second truss structure, a second moving platform and a second lifting tool. The lifting device is used for lifting the first suspension splicing device, the second suspension splicing device and the second cantilever units which are not spliced to the bridge abutment. According to the method, the safety risk in the construction process of crossing the existing railway can be reduced, meanwhile, the construction efficiency is improved, the construction time is shortened, and the method has the advantages of being time-saving, low in risk, saving, small in influence of the surrounding space environment and low in construction cost.
本发明涉及桥梁施工技术领域，公开一种预制箱梁多节段悬臂非对称拼接系统及方法。所述预制箱梁多节段悬臂非对称拼接系统包括第一悬拼装置、运梁装置、第二悬拼装置和起重装置，第一悬拼装置位于桥梁墩台的一侧，第一悬拼装置包括第一桁架结构、第一移动平台和第一吊具，第二悬拼装置位于桥梁墩台的另一侧，第二悬拼装置包括第二桁架结构、第二移动平台和第二吊具，起重装置用于将第一悬拼装置、第二悬拼装置以及未拼接的第二悬臂单元起吊至桥梁墩台上。本发明既可以减少横跨既有铁路施工时的安全风险，同时也提高了施工效率，缩短了施工时间，具有省时、低风险、节约的优点，受周边空间环境影响小，施工成本较低。
