摘要
上海虹桥国际机场T1航站楼交通中心工程位于软土地区,且周边环境复杂、文明施工要求高。为减小基坑工程施工过程对周边环境的影响,尝试采用了长螺旋钻孔压灌桩作为基坑围护,收到了理想的效果。介绍了长螺旋钻孔压灌桩施工工艺要点,并与钻孔灌注桩进行了优缺点对比,总结的经验可供类似项目参考。
Shanghai Hongqiao International Airport T1 terminal traffic center project is located in the soft soil area, with complex surrounding environment and high requirements of civilized construction. In order to reduce the impact of the foundation pit construction process on the surrounding environment, the long auger drilling and pressure-grouting piles have been used as foundation pit support and achieved ideal effects. The key points of the construction process of the long auger drilling and pressure-grouting piles have been introduced in this paper. Compared with the advantages and disadvantages of the bored piles, the summarized experience can provide references for similar projects.
