Based on the immersed tunnel element prefabrication of the Hongkong-Zhuhai-Macao Bridge, we analyzed the reinforcement cage self-steady feature and the anti-deformation requirements, propounded the method statement of anti deformation for large-scale reinforcement cage, analyzed and optimized the designing scheme of strengthening rib structure by stress simulation calculation. A binding technology of reinforcement cage with large-scale strengthening rib has been formed through practice and continuous optimization and improvement.
