Bridge and tunnel overlapping area precast beam installation method
The invention relates to the technical field of road and bridge construction, and discloses a bridge and tunnel overlapping area precast beam installation method. Before a precast beam to be installed is installed, transverse moving rails are installed on a cover beam and a bridge abutment in the width direction of a tunnel, then the precast beam to be installed is placed at a first preset position on the transverse moving rails, and then the precast beam to be installed is driven to move from the first preset position to a second preset position along the transverse moving rails. By installing the transverse moving rails, the precast beam to be installed can be conveniently moved from the first preset position to the second preset position along the transverse moving rails so as to adjust the transverse position of the precast beam to be installed. Compared with a method for installing the precast beam directly through a transverse moving bridge girder erection machine in the prior art, the bridge and tunnel overlapping area precast beam installation method is not affected by the bridge girder erection machine and the clearance of the tunnel, the precast beam to be installed is directly and transversely moved, then the precast beam at the two ends of the bridge abutment in the tunnel can be installed, the installation method is simple, and the construction efficiency is effectively improved.
本发明涉及道路桥梁施工技术领域，公开一种桥隧相叠区预制梁安装方法，待安装预制梁安装前，分别在盖梁和桥台上沿隧道宽度方向安装横移轨道，然后将待安装预制梁置于横移轨道上的第一预设位置，再驱动待安装预制梁沿横移轨道由第一预设位置移动至第二预设位置。通过安装横移轨道，能够方便地将待安装预制梁由第一预设位置沿横移轨道移动至第二预设位置，以调节待安装预制梁的横向位置。相比于现有技术中直接通过横移架桥机安装预制梁的方法，本发明提供的桥隧相叠区预制梁安装方法，不受架桥机与隧道净空的影响，通过直接横向移动待安装预制梁，即可实现隧道内桥台两端的预制梁安装，安装方法简单，有效提高了施工效率。
