Research on the Application of Digital Pier Building Machine for Bridge Super-high Pier
As an important solution for areas with fluctuating terrain and large height difference,the development of super-high pier large-span bridge construction technology plays an important role.Based on the super-high pier construction in Longchuanjiang grand bridge engineering in Chongqing-Hunan double-track expressway project,this paper makes an in-depth analysis on a series of problems such as single function,insufficient verticality control accuracy,and low intelligence degree of commonly used traditional hydraulic climbing formwork structure in the construction process of bridge super-high pier.A new type of digital pier building machine for bridge super-high pier is successfully developed,which realizes the functions of synchronous climbing of internal and external formwork,real-time monitoring of status,automatic adjustment of shape and size,etc.,ensuring the forming accuracy and quality of the pier,improving the construction efficiency and ensuring the construction safety.
