中铁七局“高标准支撑+高质量建设”打造城市建设标杆工程

Core Viewpoint - The Qiaocheng East Road North Extension Project is a significant infrastructure initiative in the Guangdong-Hong Kong-Macao Greater Bay Area, with a focus on high-quality construction and innovative building techniques [1][6]. Group 1: Project Overview - The Qiaocheng East Road North Ring Interchange, part of the project, features a total bridge length of 2887.1 meters and is the first in China to use octagonal socket-type segment assembly for bridge piers [1][2]. - The project includes two mainline bridges and eight ramp bridges, achieving an assembly rate of over 95% for the prefabricated bridge [2]. Group 2: Construction Techniques - The construction employs modular and factory-based prefabrication, allowing for simultaneous construction of pile foundations and piers, significantly accelerating the construction process [2][6]. - The installation time for prefabricated piers has been reduced from at least 7 days in traditional methods to just 1.5 days [2]. Group 3: Technological Innovations - The project utilizes advanced technologies such as dual total station positioning, laser leveling, and a hydraulic stainless steel template system to ensure precision in construction [6][7]. - An information traceability management system has been established to maintain transparency throughout the construction process, covering aspects like model specifications and quality inspection reports [6]. Group 4: Quality and Safety Management - The company emphasizes meticulous safety and quality management throughout the project, integrating smart technology and green practices to enhance construction quality [1][6]. - Proactive geological forecasting and monitoring are employed to ensure the stability of tunnel construction, with advanced monitoring systems in place [7].
