PURPOSE:To simplify reinforcing work for slope as well as save power required for the reinforcing work by a method in which I-shaped steels are vertically set in large numbers on a slope, cross iron bars are set on the I-shaped steels, they are coupled with anchors, and then cement motar is sprayed on the I- shaped steels and hardened. CONSTITUTION:A large number of I-shaped steels 1 are vertically set at intervals laterally on a slope 2, and the rib portions of the I-saped steels 1 are set jointedly with cross iron bars 3 at intervals in a latticed form. Then, anchor holes are drilled properly in the flange portions of the I-shaped steels 1 and anchors 4 are driven into the hard ground 5 of the slope 2 for fixation. Then, cement concrete or mortar 6 is sprayed on the I-shaped steels 1, and also the concrete or mortar 6 is sprayed on the peripheries of the cross iron bars 3 and hardened. |
