摘要
鸿吉商贸中心超高层建筑的基坑支护采用地下连续墙。深墙深30 m , 用于开挖时基坑支护, 同时也是建筑结构的一部分。浅墙深18 m , 仅用作基坑支护。深、浅墙均采用抓斗挖槽, 因其具有工效高、移动方便、施工无震动等特点。连续墙墙段接头采用接头管法、接头板法和型钢柱法, 均取得了较好的效果。
The underground continuous wall has been adopted in the foundation pit support of the super high building of Hongji Commercial and Trade Center. The height of deep wall is 30 m and is used as the support to the foundation pit during excavation and also as a part of the building. The height of shallow wall is 18 m and is only used as the support of the foundation pit. The clamshell excavates the deep and shallow wall troughs because it has the characteristics of high working efficient, easy to move and no vibration in construction. The continuous wall junctions are connected by the methods of junction pipe method, junction plate method and section steel pillar method and good effectiveness has been gained.
