The applications of gallery ventilation technology and energy conservation heating technology to Guanjiao Tunnel (32.645 km long and twintube single line) are introduced. The intermediate separating plate is set in the inclined shaft; the space of inclined shaft top can provide space for ventilation, transportation and drainage pipelines. The ventilation distance is shortened and the air needed is guaranteed by setting transportation gallery and ventilation gallery in main tunnel. Meanwhile, energy conservation heating system is developed and good effect has been achieved.
