The invention relates to a device for fastening a wall lining 15, 16 in a rock cavity, especially a road tunnel 10a. The wall lining 15, 16 is arranged in the rock cavity at a certain distance from the walls 12 and roof 11 of the rock cavity by the use of rock bolts 14. The wall lining 15, 16 extends freely over the regions between the rock bolts 14. A liquid-tight cloth material in outstretched state forms a rear mould 15 for the injection of a layer of gunite 16. The cloth material and the clamping members are fixed to the walls 12 and roof 11 of the rock cavity at a distance therefrom. Certain clamping members are included, together with additional reinforcement material, supported by the clamping members and associated rock bolts 14, as reinforcement in the wall lining. <IMAGE> |
