Quick disassembly and construction method for superstructure of overpass bridge
The invention discloses a quick disassembly and construction method for the superstructure of an overpass bridge, which comprises the following steps: (1) erecting a protective shed for avoiding the influence of bridge disassembly and construction at the bottom of a bridge, (2) synchronously carrying out bridge disassembly preparation work and bridge construction preparation work, (3) connecting a lifting appliance of a lifting mechanism with a lifting point of a to-be-disassembled structure, and then starting the lifting mechanism, (4) pushing equipment is started, a guide beam and a newly-built main beam are pushed, the newly-built main beam is fixed to the existing bridge pier after being in place, then the guide beam is dismantled, (5) the structure to be dismantled is put down to the newly-built main beam, and then the structure to be dismantled is dismantled; and (6) a beam lifting portal, a beam splicing support and the pushing equipment are dismantled, and construction is completed. The construction method is simple in step, reasonable in design, convenient to construct, small in safety risk and good in social effect response, the quality is guaranteed, the construction period of overpass bridge dismantling and new construction is greatly shortened, and the influence on traffic, the environment and the like under the bridge is effectively avoided.
本发明公开了一种跨线桥梁上部结构快拆快建方法，包括①在桥梁底部搭设用于避免受到拆建桥影响的防护棚②同步进行拆桥准备工作和建桥准备工作③将提升机构的吊具与待拆结构的吊点进行连接，然后启动提升机构，使待拆结构整体提升并脱离桥梁支座④启动顶推设备，推移导梁和新建主梁，新建主梁到位后将其与既有桥墩进行固定，然后拆除导梁⑤将待拆结构下放至新建主梁上，之后对其进行拆除⑥拆除提梁门架、拼梁支架和顶推设备，完成施工。本发明步骤简单，设计合理，施工便捷，安全风险小，质量有保证，极大地缩短了跨线桥梁拆除和新建的施工工期，还有效避免了对桥下交通、环境等的影响，社会效应反响良好。
