| Abstract: | In order to solve the problem of safety and quality in the construction of ventilation shaft of a tunnel, and to improve the construction efficiency, the inverted drilling rig method is adopted to carry out the construction of shaft in an efficient, safe and environment-friendly manner. In this paper, the construction technology of the inverted drilling rig is introduced in detail, with emphasis on the measures to deal with the adverse geological conditions encountered in the drilling process of the guide hole, which can provide references for similar projects. |
