Summary of tunnel construction and settlement by high water head mining method When the sleeve valve pipe is limited in the construction site, directional slant hole grouting can be targeted at the fault section to strengthen the soil. It is a one-way valve device that can only inject into the outside of the pipe and cannot return grout into the pipe. During grouting, the pressure will open the rubber sleeve outside the hole, and the slurry will enter the stratum. If the pressure outside the pipe is greater than that inside the pipe, the rubber sleeve outside the hole will automatically close. Sleeve valve pipe structure mainly consists of Φ 52 -
Construction plan of a mine tunnel Observe the water inflow according to the exploratory water hole in the tunnel face. If no dewatering is required, stop dewatering. If the water pressure and volume are large and dewatering is necessary, increase the reinjection hole. Use the method of combining dewatering and reinjection to reduce the stratum settlement, so that the influence range of the dewatering well point does not exceed the scope of the reinjection well point, forming a water screen to ensure the normal tunneling. -
