Key Technology of Industrialized Intelligent Construction of the Cable-stayed Bridge with Modular Composite Structure
The main bridge of Kongchenghe Super-large Bridge in Hefei-Zongyang section of Dezhou-Shangrao Expressway is designed as a two-span single tower cable-stayed bridge with(85+165)m cantilever spine beam.The main bridge is designed as a cable-stayed bridge with modular composite structure.The main girder and cable tower are designed as modular standard units for the first time in China.In order to improve the construction efficiency and promote the industrialized construction of bridges,the construction technology of factory prefabrication and on-site construction of modular composite structure cable-stayed bridges is formed according to the characteristics of modular composite structure cable-stayed bridges,and the fast installation technology of modular composite structure cable-stayed bridges based on self-balancing erection is proposed.Practice proves that compared with the traditional single tower cable-stayed bridge of the same scale,the construction efficiency of the modular composite structure cable-stayed bridge is significantly improved,the construction period is saved by about 6months,and it is more conducive to construction organization and quality control.
