Construction method for safety ladder cage of underwater pier continuous rigid frame bridge
The invention relates to the technical field of highway bridges, and discloses a construction method for a safety ladder cage of an underwater pier continuous rigid frame bridge. Comprising the following steps that a temporary pile sinking platform is erected; prefabricated steel pipe piles are sunk to obtain an installation foundation; a first transfer channel is erected between the temporary pile sinking platform and the prefabricated steel pipe piles; longitudinal beams are installed on the installation foundation; mounting a second prefabricated ladder cage on the first in-water pier; and erecting a third transfer passage between the first in-water pier and the second in-water pier. According to the construction method for the safety ladder cage of the underwater pier continuous rigid frame bridge, the working procedure is simple, the safety ladder cage can be rapidly erected in water flow in a low-cost and environment-friendly mode, and continuous operation can be conveniently switched between the adjacent underwater piers.
本发明涉及公路桥梁技术领域，公开了一种水中墩连续刚构桥安全梯笼施工方法。包括以下步骤搭设临时沉桩平台‑沉桩预制钢管桩得到安装基础‑在临时沉桩平台与预制钢管桩间搭设第一中转通道‑在安装基础上安设纵梁‑在纵梁上安设梯笼安装平台‑在梯笼安装平台上安设第一预制梯笼‑在第一预制梯笼与第一水中墩之间搭设第二中转通道‑在第一水中墩上安设第二预制梯笼‑搭设第三中转通道。本申请的水中墩连续刚构桥安全梯笼施工方法，工序简单，可以快速、低成本、环保的在水流中搭设安全梯笼，且便于在相邻的水中墩间转换连续作业。
