On March 11, 2020, Shaoxing City Investment Group hosted a project initiation meeting for the “Smart Bridge System: Intelligent Connector Research.” Attendees included IEC Inc.’s Technical Center Director Jason Wang, East China Sales Director Jing Wang, and R&D Chief Engineer Meng Hu. Other participants comprised representatives from Shanghai Urban Construction Design Institute, China Construction (Shaoxing) Infrastructure Construction Co., Ltd., China State Construction Eighth Engineering Bureau, and China Railway 22nd Bureau.
Jason Wang presented IEC’s core technologies, fostering technical discussions with all parties. The meeting emphasized the importance of intelligent connector research within smart bridge systems, advocating a phased, multi-project approach for development. The Jianhu Bridge was selected as a pilot site to implement IEC’s Smart Force-Bearing System and control technologies. This system monitors real-time bridge reaction forces, providing critical data for overload and void warnings, structural health assessments, and maintenance decision-making.
Jianhu Bridge, a key project for the 2022 Asian Games, spans 195 meters with a maximum span of 85 meters. It is part of Shaoxing’s West Ring Road expressway and has been recognized as one of 12 major technical research challenges for 2020 by China Railway Construction Corporation.
IEC has upgraded its BEARINGSMART system to version 2.0, enhancing it with advanced optical fiber sensors that offer high sensitivity, strong anti-interference capabilities, and a lifespan verified through 200 million fatigue cycles. The system now integrates real-time monitoring with adaptive post-monitoring adjustments, a significant leap from the earlier BEARINGSMART 1.0 deployed in the Jialing River Bridge.
The upgraded system includes:
· Prototyping and validation.
· A BIM+GIS-based software display platform.
· An overload warning system for support reaction forces.
Currently, several bearings have been installed, and the project is progressing steadily. Experts are invited to visit the Jianhu Bridge for on-site observation and guidance as the initiative moves forward.
