METHOD FOR STRENGTHENING AND CONSOLIDATING UNDERGROUND BUILDING CAVITIES, MINES AND TUNNELS, DEVICE FOR EXECUTING THE METHOD, AND ANCHORING ANCHOR BOLT IN A HOLE IN THE WALL OF A CAVITY. / P P This method consists of drilling a hole 10 whose inner diameter is larger than the outside diameter of the tube 11, to engage the tube 11 in the borehole 10 and to keep it firmly there by the inner end 11b, then to PUT A GLUE B, KA TWO CONSTITUENTS IN THE HOLE DRILLED BY THE TUBE, UNTIL THE INTERVAL INCLUDING BETWEEN THE OUTER WALL OF THE TUBE AND THAT OF THE FORCED HOLE IS EMPLOYED. / P P MINES AND TUNNELS. / P
