PURPOSE:To form a vertical slope at low cost by a method in which a banking using water-granulated slag is divided into plural hitozontal layers and tamped for every layer, temporary frames are provided on the vertical slope, and plural latticed materials with a high strength are horizontally set in the banking. CONSTITUTION:A temporary frame 8a is provided at predetermined slopes 3-4 and a temporary banking 7 is provided on the outside of the temporary frame 8a. The first layer banking l1 is constructed by tamping water-granulated slag, and the temporary banking 7 is also constructed to the height of the banking. Water-granulated slag L1 in about 50-cm area from the slopes 3-4 to the banking side is mixed with about 8% cement with a proper amount of water for stabilization. A high-strength latticed material R1 is laid in about 1-m area from the slopes 3-4 to the banking side. The same processes are repeated thereafter to form banking layers l1-l7, and then the temporary banking 7 and the temporary frames 8a-8e are removed. |
