| description | The invention discloses a water disaster treatment method for a tunnel and a roadway obliquely penetrating an aquifer. The method comprises the specific steps that design and construction data of the tunnel and the roadway are collected; dividing an inner section still water range and a peripheral drainage range for water disaster treatment of the tunnel and the roadway obliquely penetrating water-bearing rock stratum; water drainage and precipitation prediction and drainage system construction and evaluation; dynamically constructing the drainage hole and lowering a first-stage sleeve and a second-stage sleeve; grouting in an inner section still water range to form an inner section still water grouting range; and grouting is conducted on the annular strip in the peripheral drainage range, and a water sealing curtain in a larger range is formed. The method is suitable for the working conditions that the water outlet flow of the aquifer section is large, the hydrodynamic strength is large, water outlet points |
