Embodiment Construction
[0035] The present invention provides a method for designing an underground water-sealed cavern water curtain system. The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0036] Such as figure 1 As shown, the design method of the underground water-sealed cavern water curtain system provided by the present invention not only includes the design improvement of the conventional water curtain roadway 2, the horizontal water curtain hole 4 and the vertical water curtain hole, but also innovatively proposes Set grouting holes on water curtain roadway 2, and design scheme for pre-grouting treatment of weak rock mass and leakage channels in the main cavern. The specific steps are:
[0037] (1) Carry out detailed geological survey of the area to be built, and set up several main caverns 1 and traffic lanes 3 underground. In particular, the traffic roadway 3 should surround the outside of t...
