Karstic water treating method for diversion tunnel
The invention discloses a karstic water treating method for a diversion tunnel. According to the method, based on the state of exposed surrounding rocks during the diversion tunnel excavation process, and the position and the water pouring volume of a water pouring point of karstic water in the diversion tunnel, the position and development condition of a karstic water channel above the diversion tunnel is predicted. A drainage tunnel which is in space-crossing with the diversion tunnel is dug in the direction from the ground to the position of the karstic water channel above the diversion tunnel, the karstic water channel above the drainage tunnel is cut off by the diversion tunnel, the karstic water is drained through the drainage tunnel, and dangers to the diversion tunnel from the karstic water is eliminated, so that the structural safety of the diversion tunnel is guaranteed. According to the karstic water treating method for the diversion tunnel, be means of a comprehensive treating principle of 'relying mainly on discharging and combined with prevention, draining, intercepting and blocking', and a treating plan is made in accordance with local conditions, the potential safety hazard to the diversion tunnel from the karstic water is thoroughly eliminated, the possible occurrence of a water bursting risk in the diversion tunnel is effectively solved, and the structural safety of a water diversion system is guaranteed.
