Abstract Research purposes: According to the features of rapid construction of Qinghai General Main Water Diversion Channel Project from Datong River to Huang River conducted by double-shield TBM and its long-distance transport, the research was made on how to realize the long-distance centralized automatic dispatch and control of railed vehicles inside tunnel by dispatch centralization control system so as to ensure safety, continuity, effective operation and efficiency of the vehicles during rapid construction of TBM driven long tunnel.
Research methods: Based on the research and analysis of the features of railed carrier vehicle and railway signal blocking equipment, the technical measures were proposed for long-distance centralized automatic dispatch and control of railed carrier vehicles inside tunnel by dispatch centralization control system. It was decided to adopt single-track transport railed line to undertake transport with some fixed passing stations at a certain interval for construction of extreme-long tunnel based on the transport value and transport system capacity.
Research results: The introduction was given to equipment composition and control principle of dispatch and control system of railed carrier vehicle for construction of extreme-long tunnel, and the technology of realizing section blocking with station interlocking control and switching. Two control modes were presented for train entering control and section blocking control of arriving and departing trains. It proposed to adopt the Geld bus distribution control system with optical cable transmission, computer interlock and PLC control.
Research conclusions: The dispatch and control system of railed carrier vehicle used for construction of extreme-long tunnel could much increase transport capacity and efficiency of single-track railed line and provide technical reference to long-distance railed transport system for the rapid construction of TBM driven long tunnel.
