塔式起重机钢承台基础施工技术

Construction Technology of Steel Pile Cap Foundation of Tower Crane

施工有时会遇到先立塔式起重机后挖基坑的施工方法,但塔式起重机混凝土基础施工却成为难题。结合天津于家堡会议中心项目成功使用混凝土灌注桩+钢承台新技术作为塔式起重机基础的案例,详细介绍了灌注桩+钢承台的施工技术、原理,包括塔式起重机基础受力计算、钢承台受力分析、装配焊接方法、钢管桩加强措施等。

Concrete foundation of tower crane construction is a problem when tower crane set up first and then excavation. Based on Yujiapu Conference Center project in Tianjin, this paper introduced construction technology for tower cranes foundation of concrete bored piles and steel cap, including the calculation of tower foundation, force analysis on steel pile cap, assembly method and strengthening method of steel pipe pile.
