Core Insights - The project team of China Railway Sixth Group's Shijiazhuang Company has significantly improved the anchoring quality of the rail in the continuous beam construction of the Tianwei High-speed Railway project, raising the qualified rate from 56.9% to 95.4% through a small innovation in component positioning [1][2] Group 1: Project Overview - Tianwei High-speed Railway is a crucial part of the national "eight vertical and eight horizontal" high-speed rail network, specifically the Beijing-Shanghai second corridor and the coastal corridor [1] - The No. 6 bid section of the project includes the 31.907 km long Wudi Grand Bridge, which consists of 11 continuous beams [1] Group 2: Challenges and Solutions - The project faced a significant challenge with the anchoring quality of the precision-rolled threaded steel, which was below 60%, with over 72.7% of the issues attributed to non-vertical installation [1][2] - A dedicated team was formed to address the issue, focusing on quality improvement, efficiency enhancement, and safety assurance through a closed-loop process of design verification, on-site measurement, and plan optimization [2] Group 3: Implementation and Results - The team identified conflicts in the construction design that hindered the vertical installation of the threaded steel and opted for a "site adaptation adjustment" approach instead of complex design changes [2] - The optimized plan demonstrated strong adaptability, achieving a qualified rate exceeding 94% in three continuous beam sections, surpassing the preset target of 85.8%, with a further increase to 98.6% during the consolidation period [2] - The construction efficiency improved by 40%, eliminating safety risks associated with inadequate anchoring precision and saving approximately 60,000 yuan in rework costs [2]
