Construction method and construction structure for mounting prefabricated cover beam of bridge in place
The invention discloses a construction method and a construction structure for mounting a prefabricated cover beam of a bridge in place, and the construction method comprises the following steps: a gantry crane track is mounted, and a foundation of the gantry crane track is treated; the detachable gantry crane rail is assembled in a bolting mode, wherein the length of the gantry crane rails is set to be 60 m, every 6 m serves as a section, the adjacent gantry crane rails are connected through bolts, and the 60 m gantry crane rails are connected and combined into a whole; a slurry storage tank is installed, specifically, the slurry storage tank is arranged at the bottom of the bent cap, and the slurry storage tank is fixed to the pier column according to the preset position; and a cover beam is installed, and the cover beam is hoisted and installed through walking of the gantry crane on the track and adjustment of a cover beam crown block. The cover beam can be rapidly aligned in the bridge prefabricated cover beam mounting process, the safety risk of rotation and movement in the cover beam mounting process is reduced, the synchronism problem of collaborative operation of multiple devices is solved, the mounting efficiency is improved, it is guaranteed that cover beam bedding is full, the appearance quality of a pier column is prevented from being affected, and the slurry storage tank mounting and dismounting efficiency is improved.
本发明公开一种桥梁预制盖梁安装就位施工方法和施工结构，所述施工方法包括步骤：安装龙门吊轨道，将龙门吊轨道的地基进行处理；将可拆卸的龙门吊轨道进行栓接组装；龙门吊轨道的长度设置为60m，每6m一节，将相邻的龙门吊轨道之间采用螺栓进行连接，将60m的龙门吊轨道连接组合成的整体；安装蓄浆槽，将盖梁底部设置蓄浆槽，将蓄浆槽按照预设位置固定在墩柱上；安装盖梁，通过龙门吊在轨道上的行走及调整盖梁天车进行起吊及安装盖梁；其能在桥梁预制盖梁安装中使盖梁快速对位，降低盖梁安装过程中旋转、移动的安全风险，解决多台设备协同作业的同步性问题，提高安装效率，保证盖梁坐浆饱满，避免影响墩柱外观质量，提高蓄浆槽安拆效率。
