Abstract

Take Hutuo River Bridge as an example, study the key technology of construction of shaped steel-hybrid combined cable-stayed tower, due to the structural specialties of the main tower, the main tower adopts scroll modeling, elliptical gradient cross-section, double-layer end-plate bearing connection in the steel-hybrid combined section, fabrication and installation of spatially curved steel tower sections, anti-cracking control of ultra-wide section concrete tower columns, and the construction of the lower tower columns adopts the adjustable arc suspension system, which can achieve millimeter-level positioning of the main reinforcement through the strong skeleton + positioning steel plate. Adjustable arc suspension system is adopted for the construction of the lower tower column, millimeter-level positioning of the main reinforcement is realized through the strong skeleton + positioning steel plate, and “2 + 1” vertical matching assembly technology is adopted for the installation of the steel tower, which effectively improves the working efficiency.
