特长富水隧道施工涌水防控技术研究

Research on Prevention and Control Technology of Water Gushing in Extra-long Water-rich Tunnel Construction

特长富水隧道在土木工程领域是公认的难点项目,施工过程中出现的涌水现象,严重影响工程整体安全和质量。文中结合黄沙界特长富水隧道施工实例,分析隧道涌水模式,采取必要的超前地质预报手段,针对性地提出排堵结合、注浆堵水的涌水防控方案,保证了项目安全和进度,为其他特长富水隧道施工涌水防控提供了重要参考。

The extra-long water-rich tunnel is a recognized construction problem in the field of civil engineering construction.The phenomenon of water gushing during the construction seriously affects the overall safety and quality of the project.Combined with the construction example of the super-long water-rich tunnel in Huangshajie,by analyzing the water gushing mode of the tunnel and adopting the necessary advanced geological forecasting methods,a water gushing prevention and control plan combining drainage and plugging,grouting and water blocking is proposed to ensure the safety and progress of the project.It provides an important reference for the prevention and control of water gushing in the construction of other super-long water-rich tunnels.
