CONSTRUCTION TECHNOLOGY FOR TALL INCLINED LARGE-DIAMETER CONCRETE CIRCULAR COLUMNS
Keywords:
Inclined circular column, Formwork support scaffold, Construction technologyAbstract
To meet the demands of architectural form and spatial layout, tall inclined large-diameter concrete circular columns are widely used in construction projects. Taking a project in Jiaxing as a case study, there are 26 inclined circular columns on the lower three floors and 14 on the upper three floors, with a maximum height of 13.9m and an inclination angle of 76°. To address the difficulties in inclination control, safety verification of formwork support scaffolds, and compaction control during concrete placement, a collaborative support system combining traditional disk-lock steel tubular scaffolds and steel wire ropes is adopted to ensure construction safety. The forming quality is guaranteed through real-time surveying and monitoring, concrete pouring techniques, and other measures.References
