Multi-mode Technology for Reinforcing and Constructing the Channel When Using Large-tonnage Crawler Crane Work Yard with Complex Conditions

杭州东站东侧临近东广场地下结构,而站房屋盖管桁架及支撑柱吊装需采用大吨位履带式起重机。介绍了为满足履带式起重机施工作业的要求,根据该结合部区域的结构形式和场地情况进行通道多形式加固施工技术。

The underground structure of the east side of Hangzhou East Railway Station which is next to the east square, but the truss system of the roof structure and the hoisting of supporting beam need to adopt large-tonnage crawler crane. According to the structure of joint-part and the condition of work yard, this paper introduced the multi-mode technology for reinforcing and constructing channel in order to satisfy the construction requirements when using crawler crane.
