Preliminary Study on Tunnel Pre-lining Method and Machine

摘要

Mining method was mainly used for the tunnel construction in many areas of our country, which requires more human resources relatively. With the labor force Increasingly, the application of mining method was relatively limited. Pre-lining technology was used to build the pre-lining arch shell in the tunnel arch before the tunnel was excavated. With the protection of the pre-lining arch shell, the whole section or step excavation method were prior choice to realize the mechanized excavation, further to improve the construction efficiency and to save the labor costs. It was showed that the pre-lining equipment has good match with the pre-lining construction method and can meet the requirements of the pre-lining technical.
