轨道交通高架穿越结构交叉施工关键技术

Key Technology of Crossing Construction of Rail Transit Elevated Crossing Structure

轨道交通17号线徐泾北城站交通枢纽及配套设施项目,施工环境复杂,基地内有已建轨交U型高架梁,轨交穿越结构交叉施工的工况复杂,施工难度大,地铁保护要求高。按照项目施工的整体目标,以严格控制项目的进度节点为目的,研究在施工策划、技术创新、安全防护、进度管理方面的各项措施,确保整个工程的顺利推进。

The transportation hub and supporting facilities project of Xujing Beicheng station of rail transit Line 17has a complex construction environment. There are already U-shaped viaduct beams in the base,and the cross construction of rail crossing structure is complicated,difficult to construct,and the subway protection requirements are high. According to the overall goal of the project construction,in order to strictly control the progress of the project node as the purpose,this paper studies the construction planning,technical innovation,safety protection,schedule management measures to ensure the smooth progress of the whole project.
