  • Located in Songshan Mountain National Nature Reserve, the Songshan Mountain Tunnel stretches about 9.4km. In the beginning, the original design was only 4.7km long. However, to avoid the core region of Songshan Mountain National Nature Reserve, the planning department selected a new environment-friendly route, changing the tunnel entrance and position of the crossover, moving the route from the core region to the buffer region. In the end, the construction length was doubled.

  • Due to complex geology in Songshan Mountain, short construction period and heavy task, the tunneling risks and difficulties doubled. Considering such working conditions, XCMG Railway Equipment and the CCCC Ltd. subsidiary worked closely. They sent professional technical teams to collect and analyze data while making detailed construction plan. After making sufficient market comparisons and feasibility study, the CCCC Ltd. subsidiary decided to select three XCMG three-arm drill jumbos to participate in tunneling work.
