摘要
结合某工程拆除内支撑结构时,在汽车坡道处采用的钢管临时回顶措施,将外墙与汽车坡道内墙连成一个整体,起到临时加固与换撑的作用。此种钢管支顶技术达到了提高施工效率,降低工程成本的良好效果。
Aimed at a foundation pit support structure demolition project,temporary steel pipe jacking measures are adopted at the car ramp to connect the external wall and the inner wall of the car ramp as a whole,which plays the role of temporary reinforcement and support replacement.This kind of steel pipe jacking technology improves the construction efficiency and reduces the project cost.
