摘要
全套管钻孔咬合桩作为一种新型的基坑支护结构已经成功地应用于深圳、广州、中山等珠江三角洲软土地区的多个基坑工程项目中,施工工艺已较为成熟。通过介绍几个软土深基坑工程应用实例,阐述了这种支护结构的技术特点,可供类似基坑支护工程参考。
Cased secant piles as a new type of excavation supporting structure have been successfully applied in many deep excavations in soft soil engineering projects in Shenzhen,Guangzhou,Zhongshan and other Pearl River Delta.This technology has a mature construction process.This paper describes a number of soft soil deep excavation engineering application examples in order to explain the technical features of such supporting structure for pit support.This can provide reference for similar projects.
