Background
Among the tunnel excavation process, inevitably can meet the interior infiltration phenomenon of hole, according to the difference of infiltration volume, generally divide into three grade, be respectively: drying, water seepage and water dripping; linear running water and gushing water. The tunnel roof is dry and seeps water, water drops are not treated, and sparsely distributed linear running water is rarely treated. The influence of densely distributed linear running water or gushing water on the tunnel construction at the top of the tunnel mainly comprises the following four aspects: first, it is very inconvenient to walk the tunnel flowing water section, influences personnel's sight, especially during the construction at night to rivers impact the cavern bottom plate and produce great sound, hinder personnel's information transfer, lead to the safety risk. Secondly, tunnel roof flowing water is more dispersed and irregular, has left very big potential safety hazard for the power consumption. And thirdly, a protective layer is generally reserved on a bottom plate excavated by the tunnel, and the protective layer is extremely easy to damage under the conditions of flowing water corrosion and repeated rolling of heavy vehicles, so that the amount of the base is increased, and the engineering cost is increased. Fourthly, the excavation is carried out along the slope direction, accumulated water can flow to the excavation face ceaselessly, and the excavation progress of the cavern is influenced. Therefore, when dense linear flowing water or gushing water is distributed at the top of the tunnel, the dense linear flowing water or gushing water needs to be treated, the construction environment is improved, and the influence of underground water on construction safety is reduced.
