Research on Water Prevention and Control Technology for Excavated Tunnels under Rich Water Aquifer
In response to the problems of high water pressure and difficulty in controlling surrounding rock in the excavation of 61206 transport roadway under rich water aquifers,advanced directional long drilling and short drilling methods were comprehensively adopted for drainage based on site conditions.Then,deep hole grouting and anchor net spraying were used to seal the water conducting cracks and control the deformation of surrounding rock.Good results were achieved in field application.
