恐龙园中心广场拔桩关键技术研究

Key Technology Research of Pile Pulling in the Dinosaur Park Central Plaza

常州市恐龙园中心广场工程桩基础为PHC管桩,后因规划地铁斜穿该区域,需将影响地铁施工的587根管桩拔除。针对现场实际情况,总结前人有效经验,自主研发了一套拔桩系统和一套快速施工的施工方法。结果表明,该拔桩系统有效地完成了任务,节省了工期。

The pile foundation of the Dinosaur Park Center Plaza is PHC pile. Because the metro is planed to cut through the region,587 piles should be removed that influence the subway construction. For the site actual situation,after summarizing the previous experience effective,the authors research and development a pulling pile system independently and a rapid construction method. The results showed that the pulling pile system complete the task effectively,and reduce the construction period.
