超高层地下室超长倾斜钢柱整体吊装施工技术

INTEGRAL LIFTING TECHNIQUE OF SUPER-LONG INCLINED STEEL COLUMN IN SUPER HIGH-RISE BUILDING BASEMENT

依托厦门英蓝国际金融中心项目地下室倾斜钢柱的施工,对20.4 m超长倾斜钢柱的吊装技术进行综合分析、研究。总结了倾斜钢柱地面拼装、整体吊装以及倾斜钢柱防止倾覆等技术措施,采用"两层一节分段、地面拼装、整体吊装"的施工方案,提高了施工效率,保证了施工质量和安全。

Based on the construction of inclined steel column in the basement of Xiamen WINLAND international financial center project, the lifting technique for 20.4 meters long inclined steel column was comprehensively analyzed and studied. The technical measures such as ground assembly, integral lifting and anti-overturning of inclined steel column were summarized. The construction scheme of "two stories per construction segment, ground assembly and integral lifting" could improve the construction efficiency and ensure the construction quality and safety.
