摘要
以上海陆家嘴某邻江基坑工程为背景,将基坑围护桩作为永久地下室结构外墙的一部分,实现"桩墙合一";围护桩采用成桩质量可靠、垂直度好的压灌桩施工工艺;通过本项目的成功经验,为"桩墙合一"新技术的推广运用提供参考。结合项目特点,对支撑体系、坑中坑等关键问题提出了相应的技术措施,取得了良好的实施效果。
Dual-purpose pile wall was used in a deep excavation project adjacent to Huangpu River at Lujiazui district in Shanghai. The technology of auger drilling pressure-grouting pile was used to make the sheet piles be full of good quality and stability and verticality.. Through the successful practice of this project,it can provide reference for the application of new technology of " unity of support pile and basement external wall ". Combined with the characteristics of the project,technical measures were put forward to achieve good results,which included the support system and deep excavation in foundation pit.
