摘　　要：以罗湖食品大厦项目为例,提出了将塔吊基础与深基坑支护体系相结合的设计与施工技术。该技术阐述了一种不在既有内支撑结构范围外单独设置高桩承台塔吊基础的情况下,充分利用深基坑支护结构体系,使塔吊基础与深基坑支护结构体系相结合,并最终完成了塔吊基础与深基坑支护体系相结合的设计与施工。该技术与传统在内支撑结构范围外单独设置塔吊基础的技术相比,不仅减少了单独设置高桩承台塔吊基础的成本,同时有效解决了基坑支护结构施工期间垂直运输难的问题,取得了较好的经济效益,具有较大的推广价值。Taking the Luohu Food Building project as an example,the design and construction technology of combining the tower crane foundation with the deep foundation pit support system is proposed.The technology expounds a kind of not outside the scope of the existing internal support structure to set up a high pile cap tower crane foundation alone,make full use of the deep foundation pit support structure system,so that the tower crane foundation and the deep foundation pit support structure system are combined,and finally complete the design and construction of the tower crane foundation and the deep foundation pit support system.Compared with the traditional technology of setting up the tower crane foundation separately outside the scope of the inner support structure,thistechnology not only reduces the cost of setting up the tower crane foundation ofthe high pile cap alone,but also effectively solves the problem of difficult vertical transportation during the construction of the foundation pit support structure,and has achieved good economic benefits and has greater promotion value.
