摘要
以广州白云国际机场综合交通枢纽项目地铁车站北凸出部基坑工程为例,分析了基坑支护结构拆除重难点,确定采用绳锯切割方法来实现本工程基坑支护结构的拆除。详细阐述了地下连续墙、混凝土内支撑等基坑支护结构拆除及处理方法,实现了节材、节地与降噪的绿色施工。
Taking the north slope foundation excavation project of the integrated transportation hub project of Guangzhou Baiyun International Airport as an example,the key points of the demolition of the retaining structure of the foundation excavation are analyzed,the method of wire saw cutting is adopted to realize the demolition of the retaining structure of the foundation excavation.The demolition and treatment of retaining structure of underground continuous wall and concrete inner support are expounded in detail,which realize the green construction of material saving,land saving and noise reduction.
