Tunnel portal girder erection construction method
The embodiment of the invention discloses a tunnel portal girder erection construction method. The influence of weather on girder erection construction can be reduced. The method comprises the steps that a sliding way and a tackle are installed on a bridge abutment and a cover beam; the first prefabricated boundary beam is placed on the tackle through the bridge girder erection machine, the first prefabricated boundary beam is moved to the first preset position through the sliding way and the tackle, and the first prefabricated boundary beam is installed at the first preset position; a prefabricated secondary edge beam which is preset to be adjacent to the first prefabricated edge beam is placed on the tackle through the bridge girder erection machine, the prefabricated secondary edge beam is moved to a second preset position through the sliding way and the tackle, the prefabricated secondary edge beam is installed at the second preset position, and the first prefabricated edge beam and the prefabricated secondary edge beam are connected; a second prefabricated boundary beam is placed on the tackle through the bridge girder erection machine, the second prefabricated boundary beam is moved to a third preset position through the sliding way and the tackle, and the second prefabricated boundary beam is installed at the third preset position; and the other precast beams are installed at the corresponding preset positions, and all the precast beams are connected.
本申请实施例公开了一种隧道口架梁施工的方法，可以减小天气对架梁施工的影响。本申请实施例方法包括：在桥台以及盖梁上安装滑道和滑车；通过架桥机将第一预制边梁放置于滑车上，并通过滑道和滑车将第一预制边梁移动至第一预设位置，将第一预制边梁安装在第一预设位置；通过架桥机将预设与第一预制边梁相邻的预制次边梁放置在滑车上，通过滑道和滑车将预制次边梁移动到第二预设位置，将预制次边梁安装在第二预设位置，连接第一预制边梁与预制次边梁；通过架桥机将第二预制边梁放置于滑车上，并通过滑道和滑车将第二预制边梁移动至第三预设位置，将第二预制边梁安装在第三预设位置；将其他预制梁安装在对应的预设位置，并连接所有预制梁。
