Emergency disposal method for initial stage of water bursting and mud bursting in tunnel construction process

The invention discloses an initial emergency disposal method for water bursting and mud bursting in the tunnel construction process, in the initial stage of water bursting and mud bursting in the tunnel construction process, emergency disposal is conducted on a tunnel through the four steps of (1) water filtering and plugging, (2) first drainage and then irrigation, (3) advanced shallow layer reinforcing and timely surface layer supporting and (4) concrete lining construction in sequence. The initial stage of water gushing and mud bursting refers to the stage that local muddy water gushing occurs near the tunnel face of the tunnel in the water gushing and mud bursting risk tunnel section, and the situation that large-scale water flow with silt suddenly enters the tunnel does not occur temporarily. The emergency disposal method for the initial stage of water bursting and mud bursting in the tunnel construction process has the advantages of being feasible in technology, safe, reliable and convenient to implemen
