To crack the asphalt concrete tunnel lining and its support complex method

The present invention discloses a ground fissure tunnel asphalt concrete composite lining in the ground fissures affect the interval provided in accordance with the initial lining, asphalt concrete composite lining, lined, lined along the tunnel from the surrounding rock and soil to turn the axis of the tunnel a deformation joint axis intervals, at the bottom of both sides of the liner deformation joint a reserved grouting hole in the asphalt and concrete composite lining the lateral displacement installed monitors. The present invention also discloses a method to support the cracks of asphalt concrete tunnel lining compound, using a step-step excavation, mine construction method, the modified bitumen melt with sand, stone and asphalt mix made of concrete pouring material; deformation a seam filled with asphalt mastic material, flexible connecting two adjacent construction lined, lined with waterproof seam zone treatment. Simple composite liner of the present invention has a structure, convenient construction, safe and reliable for ground fissure zones or earthquake areas.
