| Abstract: | In tunnel excavation in overburden at lower horizontal section of penstock at Liziping hydropower station, pre-reinforcement is successfully applied by constructing long and large pipe shelf crossing 24m thick overburden to ensure safety in tunneling. In practice, pipe shelf hole drilling and grouting technology is improved and optimized according to real conditions. Good results are gained. |
