RESEARCH ON PRECISE POSITIONING CONSTRUCTION TECHNOLOGY OF CONCRETE FILLED STEEL TUBULAR COLUMN IN SUBWAY STATION
Based on the research on the construction technology of internal support in a prefabricated station project of Guangzhou metro line 11,this study puts forward a construction technology of prefabricated support of prefabricated metro station,which is also used as the beam of the main structure.The prefabricated support with holes is adopted to reduce the dead weight of the support,replace the traditional cast-in-situ support and also serve as the beam of the main structure.Through the application of prefabricated support,the construction process of formwork installation and removal is reduced and the construction efficiency is greatly improved,provide reference for similar projects in the future.
