Group 1: Project Overview - The Jingtai Expressway Qijizhan expansion project spans 23.999 kilometers, starting from the Yancheng hub and ending at the Yinjialin hub, and is a key project of the Ministry of Transport and a major project in Shandong Province [1]. - The project is the first of its kind in the country to implement a "Six to Twelve Lanes" expansion, addressing the long-standing congestion issues due to the original six-lane design [2]. Group 2: Technical Innovations - The project features a unique design combining an overall twelve-lane structure at the start and end points with a separated design for other sections, which is a first for similar projects in China [2]. - It introduces a comprehensive expansion method that includes side separation and widening of elevated bridges, as well as a new type of emergency rescue passage [2][3]. Group 3: Quality Control and Safety Management - A "75432" quality control system has been established to ensure high construction quality, incorporating seven strict control mechanisms and various technical guidelines [3]. - The project employs advanced safety management techniques, including a third-party safety consulting team and a comprehensive safety monitoring system utilizing drones and smart warning devices [3][4]. Group 4: Smart Technology Integration - The project integrates digital and intelligent technologies, developing a BIM collaborative management platform for online management and visualization throughout the construction process [4]. - New technologies such as "contactless payment" and "intelligent green inspection" are expected to enhance toll station efficiency by over 30% [4][5]. Group 5: Bridge Construction Innovations - The project includes the construction of a new Yellow River bridge with a main span of 530 meters, utilizing a pioneering steel-concrete hybrid bridge tower structure [6]. - Innovative construction techniques, such as a custom-built large segment intelligent bridge construction machine, have been developed to ensure precision and safety during the construction of complex bridge segments [7]. Group 6: Economic Impact - The completion of the project is part of Shandong Highway Group's commitment to the national transportation strategy, with significant investments made in major highway projects throughout the year, totaling 440 billion yuan [7].
