Project Background：
The low-vacuum magnetic levitation transport system operates in a challenging environment, where the concrete structure is exposed to low vacuum, pressure variations, and high temperatures. These factors present significant challenges to the long-term safety and performance of the system. Additionally, the issue of electromagnetic interference from steel reinforcement to the magnetic levitation system requires urgent resolution. It is necessary to develop high-performance special concrete and surface reinforcement technologies targeted for this system.
Aims & Goals:
1. To understand the performance evolution mechanism of concrete, non-metallic fiber and coating materials suffering low-vacuum;
2. To develop high performance special concrete by employing non-metallic petroleum-substrate fiber reinforcement system;
3. To innovate high quality petroleum-substrate coatings for concrete surface reinforcement in new transport infrastructure such as ultra-high speed low vacuum pipeline system.
