The Application of Hydraulic Vertical Insertion Steel Pipe Column Technology in Subway Construction with Cover and Cut-top Down Method
With the development of urban rail transit and the development and utilization of underground space,the cover and cut-top down method has become a common method in subway construction.As the main bearing and mechanical transmission structure of cover and cut-top down construction,the construction quality of steel pipe column directly affects the overall construction quality and safety of subway station.For this reason,combined with construction example of cover and cut-top down method in Xili Station of Shenzhen-Huizhou Intercity,this paper summarizes the key and difficult points of the steel pipe column construction with cover and cut-top down method,and discusses the application of hydraulic vertical insertion steel pipe column technology in the construction of subway station by the cover and cut-top down method,in order to provide reference for the construction of steel pipe column in similar subway stations.
