| titleOfInvention | A kind of newly-built antiseepage mine shaft |
| abstract | The utility model provides a kind of newly-built antiseepage mine shaft, and pit shaft includes outer tube wall and inner tube wall；Gap is provided between inner tube wall and outer tube wall, is filled in gap location using water proof material；What is be spaced on the depth direction of outer tube wall connects stubble seam provided with multiple horizontal constructions, and connects stubble in multiple constructions and sew on and be respectively provided with copper seal；Pit shaft sequentially passes through freezing top soil, freezing basement rock section and non-freeze section from up to down.The utility model uses step-like borehole wall injection molding die build the construction that wall obtains and connects stubble seam also for step-like, and the construction, which connects stubble seam, can extend infiltration lane, improve impermeability.The utility model connects stubble and sewed in construction is provided with the copper seal of arc shape, and the water-stagnating effect of the copper seal is fine, can effectively stop that the water of soil layer is flowed into pit shaft.Effectively solves the problems, such as pit shaft percolating water using a variety of closure processing modes, mine shaft of the present utility model is simple in construction, good seepage-proof property, and antiseepage operating method is succinctly easy to operate. |
