AI Technical Summary
In existing TBM tunnel construction, traditional passing platforms suffer from low transportation efficiency in sections with poor geological conditions due to insufficient traction, failing to meet the continuity and adaptability requirements of complex tunnel construction.
Design a dual-mode drive self-propelled TBM tunnel passing platform. By combining the detachable structure of the traction beam assembly and the support roller with the hydraulic power system, the platform can be towed by the TBM in normal sections and self-driven by the hydraulic cylinder in high-resistance sections, thus having a dual-mode drive function.
To ensure the continuity of tunnel transportation operations and construction safety, improve construction efficiency, reduce frictional resistance, extend equipment life, and enhance construction adaptability and safety.
